# Clinical Cases: Physical Medicine and Rehabilitation ## Case 1: Spinal Cord Injury Rehabilitation ### Patient Presentation **Demographics:** 24-year-old male college student and recreational athlete **Chief Complaint:** "I can't feel or move my legs after a motorcycle accident" **History of Present Illness:** This 24-year-old male college student was involved in a high-speed motorcycle collision 3 weeks ago when he lost control on a wet road and struck a guardrail. He was wearing a helmet. At the scene, he was unable to move his lower extremities and reported no sensation below his chest. He was immobilized with a cervical collar and backboard and transported by air ambulance to a Level I trauma center. In the emergency department, primary and secondary surveys revealed a T6 burst fracture with posterior ligamentous complex disruption and spinal cord compression. There were no other significant traumatic injuries aside from a left clavicle fracture managed conservatively. He underwent emergent T5-T8 posterior spinal fusion with decompressive laminectomy within 8 hours of injury. Postoperatively, his neurologic examination remained consistent with a complete T6 spinal cord injury. He is now 3 weeks post-injury and medically stable. He has been weaned from the ventilator (briefly intubated for surgery), his blood pressure has stabilized with discontinuation of vasopressors, and he has been started on a bowel and bladder program. He has been cleared by the spine surgery team for active rehabilitation and is being transferred to the inpatient rehabilitation unit. **Past Medical History:** - No significant past medical history - No prior surgeries - No history of psychiatric illness - Up to date on immunizations **Medications:** - Enoxaparin 40 mg subcutaneous daily (DVT prophylaxis) - Oxybutynin 5 mg three times daily (neurogenic bladder) - Docusate 100 mg twice daily - Bisacodyl suppository every other day - Gabapentin 300 mg three times daily (neuropathic pain) - Baclofen 10 mg three times daily (spasticity) - Famotidine 20 mg twice daily (stress ulcer prophylaxis) - Acetaminophen 1000 mg every 6 hours as needed **Social History:** - College senior studying engineering - Varsity soccer player and recreational motorcyclist - Lives in a second-floor apartment with no elevator (will need accessible housing) - Non-smoker, occasional alcohol use (social) - Strong family support system - No illicit drug use **Family History:** - Non-contributory - No family history of neurologic disease ### Physical Examination - **Vital Signs:** BP 108/62 mmHg (supine), 82/50 mmHg (sitting — orthostatic), HR 62 bpm (supine), RR 16/min, Temp 37.0°C, SpO2 98% on room air - **General:** Well-developed, well-nourished young male in wheelchair, alert and cooperative.

She was found by her husband with left-sided weakness, slurred speech, and left facial droop. She was brought to the emergency department within 90 minutes of symptom onset and received IV alteplase. Despite thrombolytic therapy, she retained significant left-sided hemiparesis. She completed a 3-week inpatient rehabilitation program and was discharged home 2 months ago. Since discharge, she has continued outpatient physical and occupational therapy twice weekly. Her left lower extremity strength has improved to the point where she can ambulate with a single-point cane and an ankle-foot orthosis, though her gait is slow with circumduction. However, her left upper extremity has become progressively more spastic and functionally useless over the past 6 weeks. Her left arm is now held in a flexed posture with the elbow flexed at 90 degrees, forearm pronated, wrist flexed, fingers clenched in a fist, and thumb adducted across the palm. She cannot actively extend her fingers or open her hand. She reports pain in the left shoulder (rated 6/10) and difficulty with hygiene in the left palm (maceration and odor from clenched fist). Her occupational therapist has noted plateau in progress and recommended botulinum toxin injections for spasticity management. **Past Medical History:** - Right MCA ischemic stroke (3 months ago) - Atrial fibrillation (likely embolic source of stroke) - Hypertension - Hyperlipidemia - Type 2 diabetes mellitus - Obesity (BMI 32) - Left hemiplegic shoulder pain - Depression (post-stroke) **Medications:** - Apixaban 5 mg twice daily - Metoprolol succinate 50 mg daily - Lisinopril 20 mg daily - Atorvastatin 80 mg daily - Metformin 1000 mg twice daily - Baclofen 20 mg three times daily - Tizanidine 4 mg at bedtime - Sertraline 100 mg daily - Acetaminophen 1000 mg three times daily **Social History:** - Retired schoolteacher (30 years of elementary education) - Lives with husband in a single-story home - Former social drinker, no alcohol since stroke - Non-smoker - Previously independent in all ADLs, now requires moderate assistance for dressing and bathing - Uses a single-point cane and AFO for ambulation - Unable to drive **Family History:** - Father had stroke at age 68 - Mother had atrial fibrillation and heart failure - Brother with hypertension and diabetes ### Physical Examination - **Vital Signs:** BP 138/82 mmHg, HR 72 bpm (irregular), RR 14/min, Temp 36.8°C, SpO2 97% on room air, BMI 32 - **General:** Pleasant, cooperative female ambulating with single-point cane in right hand and left AFO.

Source: Educational illustration.* ### Diagnosis **Post-Stroke Left Upper Extremity Spasticity (Modified Ashworth Scale 3) with Left Hemiplegic Shoulder Pain and Functional Limitation, 3 Months After Right MCA Ischemic Stroke** **Key Diagnostic Criteria:** - Upper motor neuron pattern spasticity with velocity-dependent increase in muscle tone - Modified Ashworth Scale 3 in elbow flexors, wrist flexors, and finger flexors - Functionally limiting: unable to use left hand for ADLs, hygiene complications from clenched fist - Hemiplegic shoulder pain with subluxation contributing to disability ### Treatment Plan 1. **Botulinum toxin injections (onabotulinumtoxinA):** Under EMG or ultrasound guidance, inject the following muscles: - Biceps brachii: 100 units (2 sites) - Brachioradialis: 50 units (1 site) - Flexor carpi radialis: 50 units (1 site) - Flexor carpi ulnaris: 50 units (1 site) - Flexor digitorum superficialis: 50 units (2 sites) - Flexor digitorum profundus: 50 units (2 sites) - Adductor pollicis: 20 units (1 site) - Pronator teres: 50 units (1 site) - Total: 420 units onabotulinumtoxinA 2. **Post-injection rehabilitation (critical window):** Intensive occupational therapy 3-5 times/week for 4-6 weeks following injection (onset of effect 3-7 days, peak effect 2-4 weeks). Stretching program, serial casting of the wrist if needed, task-specific training, constraint-induced movement therapy if candidate 3. **Shoulder pain management:** Subacromial corticosteroid injection for bursitis. Shoulder sling/support for subluxation management during ambulation. Gentle ROM exercises avoiding provocative positions. Electrical stimulation to supraspinatus and posterior deltoid 4. **Oral medication adjustment:** Wean baclofen gradually (generalized tone reduction may impair lower extremity function needed for ambulation). Continue tizanidine at bedtime for nighttime spasms 5. **Splinting:** Resting hand splint for nighttime use to maintain wrist and finger extension after botulinum toxin takes effect. Custom thermoplastic splint fabricated by occupational therapist 6. **Follow-up:** Reassess in 3-4 months for repeat botulinum toxin injections (effect wears off in 3-6 months). Consider intrathecal baclofen pump if spasticity becomes generalized and refractory. Long-term goals: improve hand hygiene, reduce pain, improve functional use if motor recovery permits ### Key Learning Points - Botulinum toxin is the first-line focal treatment for post-stroke spasticity; it selectively weakens overactive muscles without the sedation and generalized weakness caused by oral antispasticity medications - The "therapeutic window" after botulinum toxin injection (weeks 2-8) is the critical period for intensive rehabilitation, as reduced spasticity allows more effective stretching, strengthening, and motor relearning - Hemiplegic shoulder pain affects 30-70% of stroke patients and is multifactorial (subluxation, rotator cuff injury, spasticity, adhesive capsulitis, complex regional pain syndrome); a systematic evaluation is needed to identify treatable causes - Oral antispasticity medications (baclofen, tizanidine, dantrolene) should be used cautiously in stroke patients, as generalized tone reduction may impair functional mobility — particularly standing and ambulation where some tone in the lower extremity may be beneficial - The Modified Ashworth Scale (0-4) is the most widely used clinical tool for grading spasticity, though it has limitations in distinguishing neural (velocity-dependent) from non-neural (contracture) contributions to increased resistance --- ## Case 3: Traumatic Brain Injury Cognitive Rehabilitation ### Patient Presentation **Demographics:** 34-year-old male software engineer **Chief Complaint:** "I can't concentrate, I forget everything, and I can't do my job anymore" **History of Present Illness:** This 34-year-old male software engineer presents to the outpatient brain injury rehabilitation clinic 4 months after a severe traumatic brain injury (TBI) sustained in a cycling accident. He was not wearing a helmet when he was struck by a motor vehicle at an intersection. He was found unconscious at the scene with a GCS of 6 (E1V2M3). He was intubated in the field and transported to a Level I trauma center. CT head revealed bifrontal contusions, a small right temporal epidural hematoma (managed conservatively), and diffuse axonal injury with punctate hemorrhages in the corpus callosum and brainstem. He remained in a coma for 12 days (post-traumatic amnesia lasted 35 days). He underwent tracheostomy and PEG tube placement during the acute hospital stay. He spent 4 weeks in acute inpatient rehabilitation where he was decannulated, transitioned to oral diet, and regained independent ambulation. He was discharged home 2 months ago and has been attending outpatient therapies. His wife reports persistent cognitive deficits that significantly impact his daily life. He has difficulty sustaining attention for more than 10-15 minutes, cannot multitask, frequently loses track of conversations, and forgets appointments and recent events. He becomes easily frustrated and has had several episodes of verbal outbursts toward his wife and children. He attempted to return to work part-time 3 weeks ago but was unable to perform his programming tasks and became overwhelmed. His employer has placed him on medical leave. **Past Medical History:** - Severe TBI (GCS 6, PTA 35 days) 4 months ago - Bifrontal contusions and diffuse axonal injury - Right temporal epidural hematoma (managed conservatively) - Post-traumatic seizure (one episode during acute hospitalization, on levetiracetam) - No prior medical or psychiatric history **Medications:** - Levetiracetam 500 mg twice daily (seizure prophylaxis) - Amantadine 100 mg twice daily (cognitive enhancement) - Methylphenidate 10 mg every morning (attention) - Melatonin 5 mg at bedtime (sleep-wake cycle regulation) - Sertraline 50 mg daily (mood/irritability) **Social History:** - Software engineer at a tech company (10 years of experience) - Married with two children (ages 4 and 7) - Master's degree in computer science - Premorbid high functioning, no learning disabilities - Non-smoker, occasional craft beer enthusiast (abstinent since injury) - Previously active: cycling, hiking, rock climbing - Currently unable to drive (visual processing and reaction time concerns) - Wife has reduced work hours to part-time to provide supervision and support **Family History:** - No family history of neurologic or psychiatric disease - Father with hypertension - Mother healthy ### Physical Examination - **Vital Signs:** BP 122/76 mmHg, HR 72 bpm, RR 14/min, Temp 36.8°C, SpO2 99% on room air, BMI 25.4 - **General:** Well-appearing male, ambulatory without assistive device.

Source: Educational illustration.* ### Diagnosis **Severe Traumatic Brain Injury with Post-Traumatic Cognitive Impairment (Attention, Memory, Executive Function, and Processing Speed Deficits), Behavioral Dysregulation, and Impaired Self-Awareness — Rancho Los Amigos Level VII (Automatic-Appropriate)** **Key Diagnostic Criteria:** - Severe TBI by criteria: GCS 6, PTA >7 days (35 days) - Neuropsychological testing confirming severe impairments in attention, processing speed, memory, and executive function - MRI evidence of bifrontal contusions and diffuse axonal injury - Functional limitations in work, driving, and complex ADLs - Impaired self-awareness consistent with frontal lobe injury ### Treatment Plan 1. **Comprehensive cognitive rehabilitation program (3-5 days/week for 12-16 weeks):** - **Attention training:** Direct attention training using APT (Attention Process Training) program targeting sustained, selective, alternating, and divided attention. Graded computer-based exercises with progressive difficulty. Environmental modification to reduce distractions - **Memory rehabilitation:** External compensatory strategy training (smartphone reminders, written checklists, calendar system, voice recorder). Spaced retrieval training. Errorless learning techniques for new procedures. Memory notebook/planner system with structured training - **Executive function training:** Goal management training (GMT), metacognitive strategy instruction, problem-solving training, self-monitoring techniques. Use of structured routines and checklists for complex tasks - **Processing speed:** Timed practice activities with progressive demands. Computer-assisted cognitive training 2. **Speech-language pathology:** Pragmatic communication skills training (turn-taking, topic maintenance, emotional regulation during conversation). Cognitive-communication therapy 3. **Behavioral management:** Positive behavioral support plan. Anger management training. Structured behavioral feedback. Family education on TBI-related behavioral changes 4. **Self-awareness intervention:** Structured experiential feedback during therapy tasks. Video self-modeling. Discrepancy-based feedback comparing self-ratings to therapist ratings. Gradual development of metacognitive skills 5. **Medication management:** Continue amantadine 100 mg BID (evidence-based for TBI cognitive recovery). Consider titrating methylphenidate to 20 mg AM if tolerated. Monitor testosterone level (borderline low, may contribute to fatigue and mood; recheck in 3 months, consider endocrinology referral if persistently low). Continue levetiracetam (reassess at 12 months for discontinuation if seizure-free) 6. **Vocational rehabilitation:** Neuropsychological re-evaluation at 6 months. Gradual return-to-work program with workplace accommodations (reduced hours, quiet workspace, written instructions, frequent breaks, simplified tasks initially). Collaboration with employer and vocational counselor 7. **Family support:** Caregiver education and training. Family therapy. Referral to Brain Injury Association support group. Respite care resources 8. **Driving rehabilitation:** Repeat driving evaluation in 6 months after cognitive rehabilitation. Adaptive driving program if appropriate ### Key Learning Points - Post-traumatic amnesia (PTA) duration is the best predictor of long-term cognitive outcome after TBI: PTA >4 weeks is associated with severe disability and prolonged recovery, though meaningful improvement can continue for 1-2 years or longer - Cognitive rehabilitation should use a combined approach of restorative training (directly exercising impaired functions) and compensatory strategies (teaching alternative methods to bypass deficits); compensatory strategies are particularly important for memory rehabilitation - Impaired self-awareness (anosognosia) is common after frontal lobe injury and is one of the greatest barriers to rehabilitation participation and outcome; it requires specific therapeutic interventions - Amantadine is the best-studied pharmacologic agent for cognitive recovery after TBI, with Level I evidence from the IMPACT trial showing acceleration of recovery during the subacute phase - Post-TBI endocrinopathy (particularly hypogonadism and growth hormone deficiency) occurs in 25-50% of moderate-severe TBI patients and should be screened for, as it can contribute to fatigue, depression, and impaired recovery
