Study Notes

Aetiology of Stroke

Stroke is a sudden loss of brain function due to restricted blood flow, leading to cell death.
Two main types of stroke:
- Ischaemic Stroke: Caused by a blockage (usually a clot) in a blood vessel supplying the brain.
- Haemorrhagic Stroke: Results from the rupture of blood vessels in the brain.
Common cardiovascular risk factors often underlie strokes.

Common Effects of Stroke

Muscle weakness and sensory deficits on one side of the body.
Spasticity and changes in muscle tone or synergies.
Impaired balance and coordination.
Increased fatigue.
Difficulties with speech and swallowing.
Visual impairments or changes.

Hemispheric Responsibilities

Right hemisphere injuries lead to perceptual deficits and impulsive behavior.
Left hemisphere injuries cause speech difficulties and cautious behavior.
Both sides can affect memory and cognitive functions.

Case Study: Ben

52-year-old male recovering from stroke, experiencing left shoulder pain.
Aims to return to work involving extensive computer use.
Interested in using an exercise bike for fitness.

Clinical Presentation of Shoulder Pain

Approximately 50% of stroke survivors experience shoulder pain due to hemiplegia.
Common cause: Glenohumeral joint subluxation due to rotator cuff weakness and changes in tone.
Gravity, poor positioning, and improper handling during transfers can worsen shoulder pain.
Immediate post-stroke flaccidity may lead to pain from subluxation, and later spasticity can exacerbate muscle imbalances.

Management Strategies for Shoulder Pain

Electrical Stimulation: Weak recommendation for pain management.
Steroid Injections: Weak recommendation for pain reduction.
Botulinum Toxin A: Weak recommendation to alleviate pain and spasticity.
Taping: Weak recommendation to manage shoulder pain.
Acupuncture: Weak recommendation when combined with comprehensive rehabilitation.

Knee Mechanics Post-Stroke

Poor motor control following stroke can result in knee hyperextension, affecting 20-68% of individuals walking post-stroke.
Knee hyperextension leads to impaired walking speed, decreased efficiency, and potential knee pain.

Underlying Causes of Knee Hyperextension

Weakness in knee extensor muscles.
Spasticity in knee flexors.
Altered hip joint mechanics.
Muscle retraction in the paretic limb.
Limited ankle mobility/strength.
Proprioceptive disorders.

Evidence-Based Interventions for Knee Pain

No specific clinical guidelines for knee pain management in stroke survivors.
Exercise: Individualized programs recommended for improving strength.
Proprioceptive Techniques: Moderate evidence supports their use for motor control, including kinesiotaping and gait training.
Orthoses: Limited evidence for their effectiveness in addressing knee issues.

Biopsychosocial Approach

Links motor impairments to function, emphasizing that improvements in strength do not automatically translate to functional gains.
Understanding how damage in the nervous system produces various impairments aids in developing targeted rehabilitation strategies.

Description

This quiz focuses on the application of clinical reasoning skills in the context of stroke as a model for nervous system impairment. You will explore the aetiology of stroke, understand common clinical presentation characteristics, and evaluate evidence for physiotherapy interventions through a case study. Engage with the material to deepen your understanding of stroke management in a neurological population.
