Study Notes
Clinical Presentation of ALS
- Widespread muscle weakness leads to total paralysis
- Respiratory failure leads to death
- Faster degeneration in brainstem, cervical, and lumbar regions
- Limb involvement in men is more vigorous than in women
Five-Point Scale of Severity
- Stage 1: Mild disease
- Stage 2: Moderate disease
- Stage 3: Severe disease
- Stage 4: Non-functional movements
- Stage 5: Death
Prognosis of ALS
- Poor
- Death due to respiratory failure
- Death within 2-5 years after diagnosis
- Some patients may survive 5-20 years after diagnosis
Treatment (Rx)
- Medical Rx: No curative treatments, only minimal effective therapies
- Riluzole: Mildly better than placebo treatment for ALS
- Regular Vitamin-E intake: Has only minimal evidence
- Cannabis for spasticity reduction
- Multidisciplinary treatment can increase lifespan
Treatment for Muscle Spasm & Pain
- 73% of patients complain of pain in later stages
- Baclofen, NSAID, Dantrolene Sodium, Diazepam, Opioids
- Botulinum toxin injection
- Moderate exercise regimen reduces spasticity at 3 months
- Hydrotherapy with medications
- Spasm relief by stretching and increased movements
- Regular medication log needed to modify drug therapy
Treatment for Dysphagia & Dysarthria
- Dysphagia: Hydration to increase saliva viscosity to reduce aspiration
- Decongestants, antidepressants, and atropine type drugs
- Surgical removal of salivary glands or severing the PSN supply
- Percutaneous Endoscopic Gastrostomy (PEG) in severe cases
- Nutrition
- Dysarthria: Palatal lift prosthesis to reduce hypernasality
- Breathing exercises
Treatment for Respiratory Insufficiency
- Breathing exercises at early stage
- Thoracic mobility exercises
- Ventilator support for severe cases
- Oxygen therapy
- Tracheotomy
- Physiotherapy
Treatment Exercise Prescription
- Improve compliance
- Formal exercise program and enjoyable physical activity
- Include activities with opportunities for social and personal development
- Strengthening exercises: concentric > eccentric
- Endurance training not more than 15% minutes
- Adequate oxygen, hydration, and carbohydrate loads
- Avoid overwork exercise training
Physiotherapy Stage 1 Characteristics
- Mild weakness
- Clumsiness
- Ambulatory - CAN WALK
- Independent ADLs
- Rx: Continue normal activities, ROM, stretching, and yoga
- Add gentle strengthening exercises
- Provide psychological support
Physiotherapy Stage 2 Characteristics
- Moderate selective weakness
- Slightly decreased independence in ADLs
- Ambulatory
- Rx: Continue ROM, stretching to prevent contractures
- Continue cautious strengthening exercise
- Consider orthotic support
- Use adaptive equipment to facilitate ADLs
Physiotherapy Stage 3 Characteristics
- Severe selective weakness
- Moderately decreased independence in ADLs
- Easily fatigability with long-distance ambulation
- Ambulatory
- Increased respiratory effort
- Rx: Continue stage 2 program
- Continue ROM, stretching to prevent contractures
- Continue cautious strengthening exercise
- Consider orthotic support
- Use adaptive equipment to facilitate ADLs
- Encourage deep breathing exercises, prescribe wheelchair
Physiotherapy Stage 4 Characteristics
- Hanging arm syndrome with shoulder pain, edema in hand
- Wheelchair dependent
- Severe lower extremity weakness
- Increased respiratory effort
- Able to perform ADLs but fatigue easily
- Rx: Heat, massage, edema management
- Active assisted ROM exercises
- Encourage isometric exercise programs
- Arm slings, motorized wheelchair with arm rest
- Encourage deep breathing exercises
Physiotherapy Stage 5 Characteristics
- Severe lower extremity weakness
- Moderate to severe upper extremity weakness
- Wheelchair dependent
- Increasing dependence on ADLs
- Pressure sores
- Rx: Positioning, encourage family members to care for the patient
- Home modifications
- Electric hospital bed with antipressure mattress
- Active assisted ROM exercises
- Mechanical ventilation support
Physiotherapy Stage 6 Characteristics
- Bedridden
- Completely dependent on ADLs
- Rx: Dysphagia management: soft diet, tube feeding, PEG
- Positioning, encourage family members to care for the patient
- Suctioning, surgery
- Oxygen therapy
- Tracheotomy
- Electric hospital bed with antipressure mattress
- Medications to decrease impact of dyspnea
