Response

Top 5 points to make:

  1. Be compassionate and listen.
  2. Inquire about life circumstances.
  3. Consider psychology referral.
  4. Potential anti-depressant medication.
  5. Any questions?

I understand that your medical conditions are frustrating. Is there an issue with the dialysis facility that makes you not want to go? Is there anything going on in life that is making you feel sad or depressed? Do you want to kill yourself or harm anyone else? I am happy to speak with you more about any issues that I may help you with.

I can also refer you to a psychologist for further in-depth discussion of what may be bothering you.

If you are interested, I can also start you on an anti-depressant medication if it is okay with your primary doctor.

Is there anything else I can do for you?

(the key is to be empathetic and offer other resources, medical options).

Treatment

Top 5 management actions to take:

  1. Admit to the hospital.
  2. Nephrology referral for dialysis support.
  3. Neuropathic agent.
  4. Diabetic shoes.
  5. Order wound prevention measures.

This is most likely a case of uremic polyneuropathy secondary to end-stage renal disease. She most likely needs to be admitted to the acute care unit to have severe uremia managed. Addressing the cause of uremia would be to consult/communicate with the primary physician managing her CKD and dialysis. Adjusting her dialysis schedule or considering peritoneal dialysis may be beneficial.

In the mean time, symptom management may include a renal-dosed trail of a neuropathic agent.

Diabetic shoes may be offered and counseling regarding checking her feet regularly for open wounds should be provided.

Top 5 points to make:

  1. Be compassionate and understanding.
  2. Discuss the diagnosis.
  3. Resend a copy.
  4. Discuss how you will work to improve the issue.
  5. Any questions?

I apologize that you did not receive a copy of the note from this office visit. I made a note to have it sent to you, but for whatever reason it did not get to you. To update you, your patient is diagnosed with Parkinson’s disease and our treatment plan is to…

I will be sure to investigate this issue with my office staff to find out why you did not receive the note. I will also report this to our Quality Improvement team to improve physician to physician communication across the system.

I will resend a copy of this note for your records. Again, I apologize and please let me know if there are any further issues.

Treatment

Top 5 management actions to take:

  1. Neurology referral.
  2. Provide information about medications.
  3. Provide an exercise protocol.
  4. Consult PT/OT.
  5. Discuss alternative therapies.

From a medication standpoint, treatment towards Parkinson’s should be aimed at improving symptoms and protecting neurons. At this point of publication, there are not proven neuroprotective agents.

Levodopa/carbidopa – (Sinemet for example)

Remember that carbidopa inhibits the decarboxylation of levodopa in the body to make levodopa more available for the CNS.

Monoamine oxidase inhibitors (MAO)-B – (Selegiline, Rasagiline, which may also have a neuroprotective effect).

Therapy is also an appropriate consideration. Specifically, therapy can improve mobility, walking speed and balance.

More importantly; however, may be to recommend a regular exercise program. Early research suggests that vigorous exercise increased the production of brain-derived neurotrophic factor, which may be neuroprotective.

Review other treatment strategies for more advanced disease

Verrucous Hyperplasia

Top management actions to take:

  1. Education about keeping the limb clean and dry.
  2. Prosthetic adjustment for total contact.

It appears that you have developed verrucouse hyperplasia. This is thought to result from a prosthesis that fits too tightly around the limb. Venous return is cut off and this skin condition develops. Let’s send you back to the prosthetist to either add an end pad to the socket or revise the socket to improve total contact. Continue to keep it clean and monitor for signs of infection.

Phantom Limb Pain

Top 3 management actions to take:

  1. Medication management.
  2. Desensitization techniques.
  3. Rehab psychology.

We can most likely help to decrease pain and abnormal sensation with medical management. If the pain only bothers you at night and you can tolerate it during the day, maybe we will try and antidepressant, such as amitriptyline or mirtazapine at night. We can also try an anticonvulsant, such as gabapentin or carbamazepine. Let us know if they help or if you are experiencing any side effects from these medications.

Post Amputation Care

Top 5 points to make:

  1. Discuss wound care.
  2. Give information about controlling edema.
  3. Discuss post op pain control.
  4. PT/OT referral.
  5. Discuss the role of prosthetics.

  1. Wound care. Taking care of the wound itself is probably the most important post-operative issue to manage. The limb should be washed with soap and water daily, not iodine or peroxide , which could make healing difficult (unless there is an infection). Check it frequently, and avoid hitting it on anything. Also be sure to eat well, and we may give you supplemental vitamins or nutrition. Let us know if there is anything about the wound that is concerning.
  2. Swelling control. The limb will swell after surgery, and this can continue to occur for up to 1 year. One option is to give you a stockinet to slip over your stump. Another option that may provide additional benefit is a rigid dressing, which is like a cast. Typically, we will leave one on for 3-6 days that is not removable. After that we will give you a removable rigid cast so the wound can be checked and cleaned regularly. These casts can also help to prevent contractures of the knee. We will be sure to discuss these options with your surgeon.
  3. Pain.  Pain control will be similar to pain control prior to your surgery. We typically keep patients on IV pain medications for a few days and switch to pain medications by mouth as previously discussed. The most important part for you is to begin using desensitization techniques, such as massage and tapping the limb. This can greatly help to reduce your pain now and over the long-term. Our therapists can show you how to do this.
  4. Rehab. Therapy will address transfers, self-care, mobility, ambulation, range of motion, stretching, strengthening education and proper positioning of the limb to maximize your functional outcome. Expect to perform upper body exercises also, to assist with crutch or walker ambulation. Weight-bearing generally begins within a few days after the surgery and the wound does not need to be fully healed. Just be sure to keep your limb as straight as possible and avoid prolonged bending, hanging on the side of the bed, etc.
Pre-op Counseling

Top 5 points to make:

  1. Discuss the surgical options.
  2. Discuss pain control.
  3. Inform the patient about the support available.
  4. Begin a rehab protocol prior to surgery.
  5. Prescribe a formal therapy script.

This question is getting at pre-op counseling. Four areas should be addressed.

  1. Type of surgery. Of course, this is up to the discretion of the surgeon at the time of your amputation. In the case of a dysvascular limb, a closed procedure is usually performed. Other procedures include open and guillotine procedures, but are reserved for traumatic amputation or in cases of severe infection. The surgeon then anchors the muscles into the bone in a myodesis procedure or ties them to the end of the distal bone in a myoplasty. This will depend on the perfusion of the limb at the time of surgery.
  2. Pain control. We are aggressive with pain control so that you can perform you best during rehabilitation. Preferably, we would like your pain to be well-controlled prior to the surgery. Typically opiate analgesia is provided in the early stages and throughout rehabilitation. A long-acting agent is given throughout the day, and you will have a “rescue” medication to be used as needed for pain. If we need to, we can also provide nerve blocks or epidural anesthesia. We will assess your pain regularly and make adjustments as needed.
  3. Psychologic support. Of course we are here for support during this process. We can provide you with pamphlets, books or online sites to help you understand the amputation process. Family and friends are important to help you cope with the loss of a limb, but we can also provide a psychologist if needed. It is normal to feel sad, chances are that you will accept the new change well.
  4. “Pre-hab.” I would like to place you in a rehab program prior to your surgery to maximize your outcome.

What should the therapy script say?

Precautions: Cardiac

PT frequency and duration

ROM, conditioning, stretching, transfers, ambulation with one-legged gait with an assistive device, upper and lower limb strengthening

Fractures In Children: AAOS

Pediatric Ankle Fractures: Orthobullets

Tarsal Coalition and Peroneal Spastic Foot: Orthobullets

Response

Top 5 points to make:

  1. MRI/CT of the ankle.
  2. Provide a brace.
  3. Continue PT.
  4. Orthopedic referral.
  5. Any questions?

This patient most likely has a tarsal coalition, resulting in a peroneal spastic foot. Tarsal coalition is an abnormal connection between two bones in the foot.  The most commonly involved are the talus, calcaneus, and navicular.  A CT or MRI should be ordered for further evaluation.

This may resolve with conservative measures. Continued therapy and ambulation in a lace-up ankle brace may help to improve range of motion. An orthopedic evaluation is warranted in the event that conservative measures fail and a surgical resection of the coalition is needed.

Any questions?

Treatment

Top 5 management actions to take:

  1. Place the ankle in a cast.
  2. Orthopedic referral.
  3. Repeat x-ray at cast removal.
  4. Consult PT after cast removal.
  5. Give a home exercise program at cast removal.

Salter-Harris Type 1 fractures should still be treated similar to a bone fracture. In this case, casting for a total of 4-6 weeks is required. If the widened physis is greater than 2mm, then an orthopedic referral is recommended.

At follow up and cast removal, repeat x-rays may be considered, but reducing radiation exposure is optimal. If there is still significant tenderness or pain with weight-bearing, a repeat x-ray is definitely reasonable.

Be sure to evaluate ROM and gait pattern, which will likely be altered. A home exercise program may be reasonable if the child is reliable. If not, a physical therapy referral can also be considered.

In kids, always consider a growth plate injury in joints that may be “sprained.”

Response

Top 5 points to make:

  1. Be compassionate.
  2. Avoid opinions on the surgeon’s management.
  3. Suggest they discuss the case with neurosurgery.
  4. Offer rehabilitation assistance.
  5. Any questions?

I understand how you feel about this complication. I too, wish the outcome was different as this has been a difficult few years for you and your husband.

I suggest speaking with the surgeon who performed the surgery to get more clarification. As you may be aware, all surgeries and procedures have their risks and benefits, and unfortunately, a hemorrhage is a complication of surgery.

As far as suing, I can’t say because I don’t know all of the facts surrounding the surgery and complication. However, I am glad to help your husband get better from here on out from a rehab standpoint.

Any questions?

Treatment

Top 5 management actions to take:

  1. Urgent Neurosurgical consult.
  2. Headache pain control.
  3. Speech therapy consult.
  4. Education on the diagnosis.
  5. Rehab consult after surgery, if chosen.

Considering his gradual decline in function it is quite reasonable to strongly consider recommending intervention. If headaches were the only presenting symptom, more conservative management may be best. The risks and benefits must be explained, and this may be beyond the physiatrist’s scope alone.

According to Emedicine.com: 

Treatment of AVMs is best achieved with a multispecialty team comprising a neurologist, neuropsychologist, neurosurgeon, interventional neuroradiologist, and neuroanesthesiologist.

Headache management should follow standard headache/migraine headache protocols.

A speech therapy referral is also reasonable considering his academic decline and deficits in reading, writing and recognizing symbols.

Concussion: Emedicine

Concussion Statement: BJSM

SCAT3: BJSM

Response

Top 5 points to make:

  1. Be compassionate and understanding.
  2. Provide education on repeat concussions.
  3. Referral for neuropsych testing.
  4. Consider neurology referral.
  5. Any questions?

The health of your brain is most important. Researchers are still learning a lot about the long-term effects of concussions, and more specifically, repeated concussions. There are quite a lot of unknown variables.  What we know is that each concussion you sustain makes you more vulnerable to another concussion and the symptoms usually remain longer than the previous.

With that being said, I recommend further evaluation with MRI testing, neuropsychological testing and a neurology referral. It is best to make sure that there are no underlying causes for your frequent concussions and to have more than one doctor’s opinion regarding your continued play.

Overall, this is a tough decision that only you can make. Any questions about this?

Treatment

Top 5 management actions to take:

  1. She should be removed from play.
  2. Place her in the return to play protocol.
  3. Provide education on what to avoid, i.e. screen time.
  4. Discuss medication management.
  5. Discuss school restrictions.

Concussion management is rapidly evolving. However, the athlete should certainly be removed from play and not allowed to return for the rest of the day regardless of the circumstance. She should be monitored closely for any concerning change in status. She should be in the care of another responsible adult until symptoms resolve.

The mainstay of treatment is cognitive rest, and this may be relative. In general, advising to avoid alcohol use, physical activity and school is recommended. These activities can prolong healing, and may even exacerbate symptoms.  In addition, screen time should be minimized as much as possible with no screen time 1 hour prior to bed time to encourage restorative sleep.

Medications have not been shown to speed recovery, but can help with headache symptoms. It is probably best to avoid NSAIDs and prefer acetaminophen in the case of an intracranial hemorrhage.

“Being comfortable, and taking it easy” is probably the best advice at this point. Advising all-day sleep in a dark room may not be necessary for speed recovery. This, of course, is admittedly debatable.

Once symptoms resolve, or if symptoms last more than 7-10 days, the athlete should return to your clinic for further assessment. The SCAT3 should be repeated, as well as, a computer-based concussion evaluation. If the athlete is back to baseline, the return to play protocol can be instituted.

If symptoms last more than 7 days, a review of the rest period may reveal improper rest (such as going out with friend to drink alcohol, or continuing to exercise). If the athlete rested properly, considering further evaluation with an MRI or neuropsychological testing should be considered. Further counseling regarding post-concussive syndrome and second impact syndrome should be provided.

Work Up

Further evaluation remains an area of controversy and should be decided on a case to case basis. In general, a CT scan would be the imaging modality of choice. Strong consideration for ordering a CT scan without contrast should be considered if the GCS score is less than 15. In this case, she was not fully oriented which resulted in her loss of a GCS point. If there are focal neurologic findings or a deterioration in clinical status, a CT scan should be ordered.

No blood work is particularly indicated.

Response

Top 5 points to make:

  1. Be compassionate and follow the patient’s wishes.
  2. Give realistic expectations.
  3. Give prognostic information but do not be overly confident.
  4. Encourage the patient to continue to work hard.
  5. Any questions?

First and most important is to make sure that you do not violate confidentiality laws. Be sure to ask the patient if it is okay for you to answer that question in front of others if this has not already been expressed.

Overall, the prognosis for near to full recover is good. Each case is different, but we expect your strength and ability to function to continually improve day to day. We will no more as time progresses. We typically see the most recovery in the first 6 months to one year.  In the mean time, keep doing your best in therapy and continue to learn as much as you can about your condition. Any questions?

Treatment

Top 5 management actions to take:

  1. Spine surgery consult.
  2. PT/OT and maybe ST consult.
  3. Start bowel and bladder programs.
  4. Discuss neuropathic pain management.
  5. Order wound prevention measures.

Neurosurgery/orthopedic surgery should be consulted to evaluate the surgical indication on a case by case basis. Studies conflict in comparing no surgery vs early surgery vs late surgery in recovery. Generally, if a patient is functionally improving, most surgeons would not intervene.

An inpatient rehabilitation admission if vital in recovery. PT/OT and speech therapist should be consulted. Physical and occupational therapists will help to address the unique issue of immobility associated with patients with central cord syndrome. Because hands are generally weaker than legs, patients have difficulty using an assistive device to ambulate and a platform walker is preferred. The fall risk is high in these patients. Completing ADLs with a likely cervical orthosis or recent cervical fusion can also present as a barrier to progress.

Medically, these patients often have a neurogenic bowel and bladder; however, 52-84% recover urinary function. Issues with skin, neuropathic pain and spasticity must also be addressed.

  1. Acknowledge his thoughts.
  2. Explain the evidence.
  3. Inform him to discuss this further with his PCP/endocrinologist.
  4. Offer second opinions.
  5. Any questions?

Yes sir, you are right that there has been some evidence of immunosuppressive therapy being beneficial in helping to improve pain. However, in reviewing all of the available evidence, a Cochrane review reported that evidence was lacking concerning benefit of immunosuppressive therapy. Also, immunosuppressive therapy is not without risks. This should improve with time, improved blood glucose control and therapy. If you would like a second opinion, please feel free to get one. My office staff can help you schedule this if you would like. Any questions about this?

Treatment

Top 5 management actions to take:

  1. Urgent PCP/endocrinology referral to adjust glucose control.
  2. Outpatient PT/OT.
  3. Exercise program education.
  4. Diabetic shoe/sock prescription with wound prevention education.
  5. Consideration for neuropathic pain regimen.

Recovery from diabetic amyotrophy can be slow. Management of blood glucose is of utmost importance in treatment. Diet and exercise habits should be addressed. It is reasonable to consult an endocrinologist to help with management considering his poor control. While he lost 40 pounds (which raises concern for cancer), extensive weight loss can be associated with diabetic amyotrophy. But cancer needs to be ruled out.

From a rehabilitation standpoint, he has fortunately not lost enough independence to require an inpatient admission; however, if he were worse, this could be considered. Instead, he should be prescribed an assistive device to assist with ambulation and sit to stand maneuvers. He would likely benefit from outpatient physical therapy to assist with strengthening, stretching exercises and to also help with gait training.

He should also be prescribed diabetic shoes and be counseled on the importance of checking his feet daily.

Nerve pain can also be addressed with various medications (gabapentin, capsaicin, etc.).

Thank you for your question. There is a graded chart that includes pitch count recommendations related to age. I do not know the exact numbers, but I can give you a reference before you leave today. Also please give this reference to your child’s league administrators as these rules should be used for all players. I am also happy to write his limitations on a prescription pad if needed. Any questions?

Treatment

Top 5 management actions to take:

  1. Rest.
  2. Potential use of sling depending severity.
  3. PT consult.
  4. Graded return to play.
  5. Pitch count and cross training.

This is a straightforward case of Little Leaguer’s Shoulder, or more specifically, a Salter-Harris I proximal humeral fracture. The x-ray in this case does confirm the diagnosis. It also helps to decrease the likelihood of a tumor or fracture. An MRI/MRA is not necessarily indicated at this point considering the provided history, exam and x-ray findings. However, if symptoms do not gradually improve, an MRI/MRA may be ordered to consider other pathology.

For treatment, rest is best. Depending on the severity of pain, a sling for a short time may be helpful. Physical therapy should be initiated, for stretching in the initial stages. Once asymptomatic, a graduated throwing program can be initiated. It must be stressed that pain is the limiting factor in progression.

I understand that you have been through a lot these past few months. It is also unfortunate that your discharge plans are limited.

Because of your limited discharge options, I am happy to call the medical director of your insurance company to see if we can extend your stay to help you achieve another level of function. In the event that a nursing home is your only option, you will then be able to take better care of yourself without much assistance if your function improves with an extension.

Also, many young people in your similar situation are in nursing homes while they recover. It is still early in your disease course, so there is still a chance that you can improve. If you are willing, continue to contact family members and friends that may be able to help you. We will also continue to look for various resources through medical societies that may be able to help. Do you have any questions about this?

Treatment

Top 5 management actions to take:

  1. Admit to the hospital.
  2. Neurology consult.
  3. Counsel the patient on the diagnostic possibilities.
  4. Immunosuppressant agents.
  5. PT/OT consult.

This is a complicated case considering that the absolute diagnosis is unclear. However, it is clear that there is a non-traumatic spinal cord myelopathy. Neurology should be consulted and the patient monitored closely.

Considering the characteristics of the lesion on MRI, chances are this is an early presentation of multiple sclerosis. The plaque is characteristically located in the dorso-lateral cord and does not expand more than 2 segments. Lesions in transverse myelitis typically expand 3-4 segments. Although the brain MRI is negative, lesions that involve solely the spinal cord are present in 5-24% of patients.

Keep in mind that dissemination of lesions/attacks in time are important in diagnosing MS. Because there is one lesion and only one attack, transverse myelitis is most likely the proper diagnosis at this point. However, it is important to counsel the patient that MS is still a possibility.

As far as treatments, aggressive immunosuppression (IV corticosteroids, plasma exchange) would be the initial treatment for both transverse myelitis and MS.

In addition, a rehabilitation admission should be considered after acute treatments are complete. She will not only need daily PT/OT, but will also need to learn how to manage her bowel and bladder. A wheelchair evaluation/assistive device is also appropriate depending on her functional level at discharge.

You may also advise your dad that he should be the only one taking medications prescribed to him. I do understand that your pain can be difficult to tolerate, but let’s work together to come up with a better solution to control your pain. Research is conflicting concerning the use of opiates for CRPS. Because of the risks associated with chronic opiate use, let’s continue to try different non-opiate measures to help treat your pain. Later on, it may be reasonable to try opiates if they have worked for you. We are going to get you through this. Any questions?

Depression

Top 5 points to make:

  1. Listen to the patient.
  2. Ask for the psychologist’s recommendation.
  3. Explain the pros/cons of psychotherapy vs medication management.
  4. Check back with the patient often on mood and effectiveness of treatment.
  5. Any questions?

In the case of post-stroke depression, anti-depressant medication is more appropriate than psychotherapeutic intervention. Psychotherapeutic intervention is both expensive and requires a significant amount of staff time and expertise. Further, improvements may take many weeks.

Treatment

Top 5 management actions to take:

  1. Emergent admission and Neurology consult with code stroke.
  2. Out of the time frame for tPA.
  3. Permissive hypertension.
  4. Consult PT/OT/ST.
  5. Rehab Medicine consult.

The main goal of stroke therapy is to restore blood flow to the brain and preserve the penumbra. tPA, and intra-arterial recanalization techniques are best when performed early to save ischemic brain cells. Stroke evaluation should be completed within 60 minutes upon hospital arrival and tPA given within the first 3 hours if appropriate. An anti-platelet agent should be given. The threshold for blood pressure control is 220/120, as too low of a blood pressure or strict control can decrease blood flow to the penumbra.

Occupational therapy, physical therapy, speech therapy, and physical medicine and rehabilitation experts should be consulted within the first day of hospitalization.

Cardiac Rehab

Cardiac rehabilitation involves 3 different phases to help you recover.

Phase 1 takes place in the hospital setting and is focused on intense cardiac monitoring. Early mobilization, such as walking around the room and up and down stairs get you moving early. Once you are stable for discharge you will enter the second phase of cardiac rehabilitation.

Phase 2 involves going to an outpatient cardiac rehabilitation center 3 times a week for 12 weeks. Here you will perform about 30 minutes of exercise on a treadmill or exercise bike while having your heart monitored with telemetry. A nurse will monitor your heart and a cardiologist is always on-call. You will also receive education regarding ways to lead a heart-healthy lifestyle.

Phase 3 occurs once you have finished 3 months of outpatient cardiac rehabilitation and is focused on continuing to exercise and lead a heart-healthy lifestyle on your own. You will learn how to exercise at home or in a gym. From here you will continue the healthy habits that you have formed over the past few months.

Cardiac rehabilitation has been shown to help in various research studies and is supported by the American Heart Association.

Top 5 questions to ask:

  1. Anything bring on these symptoms?
  2. Any shortness of breath?
  3. Any chest pain?
  4. Has this happened before?
  5. What is the past medical history?

Examinee should also ask all other questions regarding the history of present illness (ROS, Meds, etc).


HPI:  A 59-year-old male presents to the hospital with worsening nausea and shortness of breath. He just caught a big fish and first attributed his symptoms to his excitement and fatigue, but nausea continued to worsen. He decided to leave early, and by the time he got home he noticed that he was also short of breath. When he reached the emergency room, he still did not have chest pain, but symptoms continued to progress.

Response

Top 5 points to make:

    1. Be compassionate.
    2. Give realistic expectations.
    3. Will have a better estimate with time.
    4. Will admit to rehab to address needs at current functional level.
    5. Any questions?

The physician should always attempt to avoid giving false hope when discussing prognosis and functional return. Unfortunately, the data we have about functional prognosis after spinal cord injury is in the traumatic spinal cord injury population and not the vascular population. Although this patient has a compression mechanism, he also has signs of ischemia on MRI/MRA.  You should inform the patient that his function after surgery, his AIS exam after surgery, and functional return over the next few weeks will be very helpful in further addressing the question.

As always, ask if there are other concerns/questions.

Treatment

Top 5 management actions to take:

  1. Admit to the hospital.
  2. Urgent surgery referral.
  3. Start bowel and bladder programs.
  4. Consult PT/OT when appropriate.
  5. Order wound prevention measures.

A vascular surgery/neurosurgery consult should be placed urgently to evaluate for possible decompression.  In addition, foley should be kept in place and the patient should be started on a bowel regimen for upper motor neuron bowel.  Pressure relief ankle foot orthosis should be applied and skin care should be undertaken.  Consult PT/OT when appropriate. Close follow up by the PM&R team should be continued in order to evaluate if return occurs after surgery.  In addition, this patient will make a great inpatient rehab candidate and should be admitted as soon as the patient is medically stable.

Differential Diagnosis

Leading diagnosis: Anterior Spinal Cord Syndrome

Differential diagnoses to include: Epidural abscess, compressive tumor, aneurysm, dissection, stroke, acute disc herniation. Other possible causes of his symptoms include AIDP, and syphilis.

Case #38 Labs and Test Results

Italicized words = examiner response.


Check Syphilis antibodies considering sensory exam – Syphilis studies are normal.

Check CT with and without contrast to rule out compression/fracture – CT does not show fracture but does show compression of the anterior spinal cord in the lower thoracic level.

Check MRI/MRA with and without contrast to further evaluate compression lesion –  MRI/MRA with contrast further defines this as a likely aneurysm of the anterior spinal artery compressing around the T10 level. Signs of ischemia along the anterior section of the spinal cord are also present at the same level as the aneurysm.

Check EMG to evaluate acute onset lower extremity numbness and weakness – The EMG is deferred due to the above findings.

Physical Exam

Top 5 questions to ask:

  1. What are the vital signs?
  2. What is the upper and lower extremity strength exam?
  3. Is pinprick, light touch, pain and temperature, proprioception, and vibration intact?
  4. What are the reflexes?
  5. Is there sacral sparing?

The examinee should also ask about the general exam (heart, lungs, abdomen, etc).
