    Study Notes

    Multiple Sclerosis (MS)

    • MS is an immune-mediated inflammatory disease
    • It attacks the myelin sheaths of axons in the central nervous system (CNS)
    • This leads to demyelination, which affects white matter
    • The predominant age of onset is 20-40
    • Worldwide incidence is approximately 0.1%
    • The risk of developing MS in first-degree relatives is 1-3%
    • MS prevalence is higher in Northern European descent and in temperate climates, but the geographical gradient is decreasing
    • The disease course is highly variable and unpredictable
    • The condition involves two primary pathogenic processes: an inflammatory demyelinating process and a neurodegenerative process
    • This can lead to disability
    • Multiple factors are implicated in the development of the disease, including environmental factors, genetic factors, and autoimmune processes.
    • Symptoms are varied and can include sensory, motor, bladder, and cerebellar dysfunctions
    • Visual changes, such as optic neuritis, and oculomotor nerve dysfunction can occur

    Clinical Picture

    • Any myelinated area of the central nervous system (CNS) can be affected
    • Sensory manifestations are common
    • Lhermitte's sign is a frequent symptom
    • Optic neuritis is a common symptom
    • Speech, motor disorders (paraplegia, quadriplegia), ataxia, bladder dysfunction, and precipitancy are other possible symptoms

    Pathogenesis

    • T cells are primed by antigen-presenting cells (APCs) in lymph nodes
    • The blood-brain barrier (BBB) becomes permeable to leukocytes
    • T cells interact with macrophages and microglia
    • Cytokines are released
    • Demyelination of neurons occurs

    Course of Disease

    • Relapsing-remitting MS (RRMS): Characterized by periods of relapse followed by recovery
    • Secondary progressive MS (SPMS): RRMS progression to a continual disability increase
    • Primary progressive MS (PPMS): Gradual decline in neurologic function from onset

    Diagnosis

    • MRI
    • Evoked potentials (visual, auditory, somatosensory)
    • CSF analysis

    Treatment

    • Treatment for attacks (relapses): Short course of corticosteroids
    • Long-term therapy (disease-modifying therapy): Interferon
    • Symptomatic management

    Assessment of the patient

    • Expanded Disability Status Scale (EDSS)

    • Method to quantify disability in MS and monitor changes over time

    • The EDSS assesses various functional systems including pyramidal, cerebellar, brainstem, sensory, bowel, bladder, visual function, mental status.

      Functional Systems for Scoring EDSS

      • Pyramidal functions: Relates to muscle strength
      • Cerebellar functions: Deals with coordination and balance
      • Brainstem functions: Implicates cranial nerves and bulbar function
      • Sensory function: Relates to perception
      • Bowel and bladder function: Assessment of bowel and bladder control
      • Visual function: Examines visual acuity, field, scotoma, and disc pallor
      • Mental functions: Includes fatigue and cognition.

    Assessment of Fatigue

    • Examining the threshold, frequency, and the length of required rest periods
    • The Fatigue Severity Scale (FSS) assesses the severity of fatigue based on a 9-item scale measuring its effect on activities and lifestyles

    Gait Assessment

    • Observation
    • Analysis (kinetics, kinematics)
    • 6-minute walk test (6MWT)

    ADL Assessment

    • Functional Independence Measure (FIM)

    Physical Activity

    • More sedentary behavior
    • Loss of aerobic capacity
    • Impaired muscle strength in MS patients
    • More comorbidities

    Physiotherapy Interventions

    • Every patient's needs vary
    • AIMS (during attacks): Relaxation exercises, psychological reassurance, respiratory exercises, prevention of secondary complications
    • AIMS (during remission): Varying needs depending on patient symptoms and condition

    Sensory Treatment

    • Sensory re-education: Strategies to increase awareness, compensate for loss, and promote safety (e.g., using rough materials for hypoesthesia)

    Deep Sense Treatment

    • Strategies for deep sense deficit: Targeting sensory deficits, promoting safety, using verbal cues, biofeedback, proprioceptive loading, and resistance bands

    Pain Management

    • Pain management strategies in MS: regular stretching, massage, ultrasound, hydrotherapy, postural retraining, stress management, biofeedback, and medication.

    Motor Dysfunction Treatment

    • Treatment varies based on specific symptoms (ataxia, spasticity, weakness)
    • Strengthening exercises
    • Functional exercises
    • Aerobic exercise
    • Coordination exercises

    Postural Control and Gait Exercises

    • Includes various exercises like standing, balance exercises
    • Changing positions

    Treatment of Vertigo

    • Vestibular Rehabilitation Therapy (VRT): Promoting vestibular adaptation
    • Habituation exercises: reducing magnitude of response
    • Cawthorne Cooksey exercises:

    Mental Function Assessment

    • Impaired memory, concentration, attention, depression, anxiety, and emotional liability

    Patient and Family/Caregiver Education

    • avoiding fatigue and heat
    • Importance of sufficient recovery period between exercises, tasks
    • education on disease process, clinical manifestations

    Bladder Rehabilitation

    • Lifestyle modification
    • Pelvic floor exercises
    • Biofeedback
    • Core stability exercises
    • Tibial nerve stimulation

    ADL and Hand Function Assessment

    • Occupational therapy interventions
    • Orthotics and assistive devices for stability and independence

    Cranial Nerve Examination

    • Optic nerve (visual field, acuity, reflexes)
    • Oculomotor, trochlear, and abducent nerves (eye movements)
    • Trigeminal nerve (sensory branches, mastication)
    • Facial nerve (rare) (facial expressions)
    • Vestibulocochlear nerve (vertigo)

    Temperature Control and Cooling Therapy

    • Pre-cooling or cooling during and after therapy to potentially decrease fatigue and improve physical training

    Cognitive Behavioral Therapy (CBT)

    • Reported as a reduction method
    • using specific neurocognitive rehabilitation programs for improving motor planning and stress management
