Study Notes
Amyotrophic Lateral Sclerosis (ALS)
- Etiology: 5-10% genetic; 90-95% sporadic (oxidative stress or immune abnormality).
- Life Expectancy: 3-5 years from onset.
- Mean Age Onset: 57 years.
- Gender Prevalence: Men are affected 1.5-2 times more frequently.
- Diagnosis: Electromyogram, gene testing, nerve conduction studies.
- Pathophysiology: Death of upper motor neurons (UMN) and lower motor neurons (LMN) leads to muscle atrophy and eventual loss of function in speaking, eating, breathing, and mobility.
- Signs and Symptoms: Muscle weakness, fasciculations, swallowing/speech difficulties (if corticobulbar involved), cognition initially unaffected but risk for dementia later, spasticity.
- Possible Complications: Respiratory failure, pneumonia.
- Functional Impairments: Loss of mobility, inability to speak, inability to walk.
- Treatment Approaches: No cure; medications manage symptoms (pain, sleep disturbance, spasticity, fatigue, saliva).
- Therapeutic Assistant (TA) Role: Transfers, positioning, environmental adaptations, equipment education to patients and families, equipment provision, maintaining range of motion (ROM) and strength, mental health support.
Multiple Sclerosis (MS)
- Etiology: Unknown; genetic predisposition, infection triggers, abnormal immune response (inflammation and CNS damage), obesity, smoking, low vitamin D, geography, and environmental factors.
- Life Expectancy: Minimal change; significant impact on quality of life.
- Mean Age Onset: 32; typically between 20-50 years of age.
- Gender Prevalence: Women are affected 3 times more frequently.
- Pathophysiology: Immune-mediated disease attacking the Central Nervous System (CNS); inflammation damages myelin sheath and axons, slowing or preventing message transmission.
- Signs and Symptoms: Initial symptoms include bladder dysfunction, walking problems, and vision issues; also bowel dysfunction, MS hug (dysesthesia), spasticity, numbness/tingling, pain/itching, vertigo, emotional changes (mood swings), cognitive changes (short-term memory, learning, slow processing), depression, fatigue (worsens with heat/humidity). Less common: taste/hearing loss, breathing issues, tremors, speech/swallowing issues.
- Possible Complications: Suicide, severe fatigue, chronic pain, falls, seizures.
- Functional Impairments: Inability to walk, inability to see.
- Treatment Approaches: Modify disease, treat relapses, manage symptoms, promote function, provide support (emotional), find MS care provider.
- TA Role: Assistive aids (showering, energy conservation), assistive aids (cooking, energy conservation), environmental modifications, education on relapses/remissions, mobility equipment, exercise programs, social connections (online groups).
- Definitions: Uhthoff's phenomenon (exacerbation of symptoms with heat), clinically isolated syndrome, relapsing-remitting, primary progressive, secondary progressive.
Spasticity
- Etiology: Upper motor neuron (UMN) lesion; velocity-dependent increase in tonic stretch reflexes.
- Signs and Symptoms: Joint/muscle stiffness, exaggerated muscle jerks, abnormal posture/position, pain.
- Possible Complications: Skin breakdown, pain, permanent muscle shortening.
- Functional Impairments: Inability to walk, self-feed, dress, drive.
- Treatment Approaches: Maintain muscle length, relaxation techniques (knowing triggers), medications (baclofen, botulinum toxin), functional electrical stimulation (FES).
- TA Role: Education on positioning, splint use, exercises for active and passive range of motion (A/PROM).
- Definitions: UMN lesion vs. LMN lesion characteristics, tone, rigidity, flexor spasticity, clonus spasticity, spastic paralysis, flaccid paralysis.
Parkinson's Disease
- Etiology: Unknown; likely a combination of genetic and environmental factors. Increased risk with age.
- Mean Age Onset: 65; 10% onset before 50.
- Gender Prevalence: Men are affected 1.5 times more frequently.
- Diagnosis: Alpha-synuclein misshapen protein clumps (Lewy bodies) accumulate in the substantia nigra, slowing dopamine production.
- Signs and Symptoms: Rigidity, bradykinesia/akinesia, resting tremor, decreased arm swing, poor balance, festination, freezing, stooped posture, difficulty standing/turning, dysarthria/hypophonia, mask-like face, micrographia, anxiety, depression, apathy, hallucinations, delusions, sleep disturbances, fatigue, loss of sense of smell, cognitive decline.
- Possible Complications: Falls, head trauma, suicide.
- Functional Impairments: Difficulty walking, sleeping, social interaction.
- Treatment Approaches: Medications (dopamine), surgery (deep brain stimulation), exercise, complementary therapies, bilateral movements, mental rehearsal.
- TA Role: Exercise programs, balance work, maintaining ADLs, gait training (visual, auditory, kinesthetic aids).
Progressive Supranuclear Palsy (PSP)
- Etiology: Faster progression than Parkinson's; onset in late middle age. Abnormal protein tau accumulation in brain regions causes neuron death.
- Signs and Symptoms: Difficulty walking, loss of balance, difficulty swallowing, slowed/slurred/monotone speech, slow eye movements, difficulty looking up/down, eye lid control issues, involuntary eye closing, decreased blinking/difficulty opening, head movements instead of eye movements, depression, lack of motivation, changes in judgment, insight, problem-solving, apathy, irritability, sudden laughing/crying/anger, personality changes, mask-like face, sleep problems.
- Possible Complications: Pneumonia, choking, head injuries.
- Functional Impairments: Falls, mobility, difficulty with transfers, feeding/dressing/driving, social interaction, safety risks due to cognition changes.
- Treatment Approaches: Botox for eye symptoms, antidepressants.
- TA Role: Aids and education, exercise programs, compensatory strategies.
Huntington's Disease
- Etiology: Mutation in the huntingtin gene causes brain cell death.
- Onset: Middle age.
- Life Expectancy: 15-20 years after onset.
- Signs and Symptoms: Clumsiness, postural instability, chorea, muscle rigidity, apathy, inability to concentrate, depression, mood swings, psychosis, cognitive decline, dementia, speech difficulties, swallowing difficulties, weight loss, tremors, insomnia, fatigue, seizures.
- Possible Complications: Pneumonia, suicide, extreme weight loss, violence.
- Functional Impairments: Safety risks, strained relationships, loss of speech/walking/feeding/driving, bed bound.
- Treatment Approaches: Antipsychotics/antidepressants, pre-birth testing, mobility aids, fall prevention, assistive devices, harm reduction, seating/positioning.
- TA Role: Mobility/provision and education, fall prevention, equipment adjustment, repair.
Charcot-Marie-Tooth Disease (CMT)
- Etiology: Mutation in genes supporting proteins of the peripheral nervous system (PNS); damage to axons/myelin sheath affecting long nerves first.
- Signs and Symptoms: Initial weakness in hands, feet, arms, legs, reduced muscle bulk/reflexes, sensory loss, foot/orthotic issues, progressive paralysis, high-stepped gait, balance issues, inverted champagne bottle shaped legs, reduced senses, difficulty with fine motor, diminished proprioception, hip displacement, contractures, nerve pain, fatigue, hearing loss.
- Possible Complications: Chronic pain, deformities from muscle imbalance, swallowing/breathing issues.
- Functional Impairments: Falls, loss of independence in ADLs, safety risks, reduced socialization due to hearing loss.
- Treatment Approaches: Hearing aids, orthopedic surgery, medications, pain relief, splinting (AFOs, hand/finger), exercises (maintain strength/ROM/cardio), assistive devices.
- TA Role: Splinting fitting, exercise programs, assistive device provision and education.
Muscular Dystrophy (MD)
- Etiology: Group of genetic myopathies; primarily affecting men; hereditary X-linked (females are carriers). Dystrophin protein production is abnormal/insufficient.
- Life Expectancy: Without treatment, adolescence; with treatment, 20-30s.
- Pathophysiology: Duchenne's MD (no dystrophin): Rapid muscle fiber destruction and replacement by fat/scar tissue. Becker's MD (abnormal dystrophin): Slower muscle fiber destruction.
- Duchenne's MD Progression: Gradual loss of fine/gross motor skills, muscle weakness, wheelchair dependence, non-invasive ventilator, cardiac/respiratory complications.
- Signs and Symptoms: Delayed developmental milestones, falls, pseudohypertrophy of calves, abnormal gait, Gowers maneuver, anxiety, depression. Specific gait characteristics include shoulder back, belly forward, foot drop, Achilles tendon contracture, thick calves, locked knees, weak glutes.
