Lower Extremity Orthotic Treatment in Stroke Rehabilitation
Orthotic approaches and motor learning-based neurophysiological methods are crucial in stroke rehabilitation. Traditionally used in the subacute phase, recent studies indicate that early use of orthotics in the acute phase enhances patient functionality.
Orthotics in stroke rehabilitation aim to prevent complications and provide functional independence, adapting to both acute and chronic phases. They support neurophysiological treatments, maintain ankle neutrality, prevent contractures, correct walking compensations, and offer sensory input through proper positioning and joint stabilization.
Types of Orthotics:
Positioning Orthoses:
- Used early to maintain proper positioning during bed rest and ambulation.
Functional Orthoses:
- Provide biomechanical support for walking, conserving energy to combat fatigue common in stroke patients. Examples include in-shoe supports, insoles, and shoe modifications for addressing deformities like inversion, flexion, extension, and equinus deformities.
Static Ankle-Foot Orthoses (AFO):
- Commonly used to keep the foot in a neutral position during walking. They provide correct sensory input, prevent synergistic walking patterns, facilitate balance, and reduce energy consumption and fatigue.
- Knee Orthoses:
- Address knee problems such as genu recurvatum due to quadriceps weakness, spasticity, or plantar flexor issues. They may involve AFOs or specialized orthoses like Supracondylar Recurvatum Orthosis or Swedish Knee Cage.
Walking Orthoses (KAFO, HKAFO):
- Used for patients needing long-term support, although they are generally avoided in stroke rehabilitation due to their extensive support. Suitable for those unable to regain ambulation after multiple cerebrovascular events or prolonged acute care.
Using appropriate orthotics can significantly improve postural control, gait velocity, and overall mobility in stroke patients by addressing specific biomechanical issues and supporting the recovery process.
