Sensory Recovery in Stroke-Affected Fingers

Primary Intervention: Task-Specific Motor Practice

The American Heart Association recommends intensive, repetitive task-specific training focusing on functional activities that challenge the affected fingers, as this approach has been shown to improve tactile sensation 1, 2
Task-specific training should involve repeated, challenging practice of functional, goal-oriented activities that require use of the affected fingers, promoting neural reorganization and increasing proprioceptive feedback to the central nervous system 1

The American College of Rehabilitation Medicine suggests that Functional Electrical Stimulation (FES) applied to the affected hand and forearm muscles is reasonable to consider as an adjunctive therapy, particularly within the first 6 months post-stroke, as it promotes neural reorganization by providing sensory input and facilitating more complete muscle contractions 3, 4
FES should be used as an adjunct to motor practice rather than as a standalone treatment, with strong evidence supporting its efficacy for individuals less than 6 months post-stroke 3
Somatosensory retraining to improve sensory discrimination may be considered for stroke survivors with somatosensory loss, directly targeting sensory deficits through graded sensory discrimination tasks 2

Early intervention within the first 6 months post-stroke shows stronger evidence of efficacy, though recovery can occur even years after stroke with intensive therapy 3
Emphasis should be on progressive task difficulty, repetition, and functional practice, with shorter, more time-intensive programs appearing comparable to longer, less time-intensive programs 5, 6, 7

The American Academy of Physical Medicine and Rehabilitation recommends avoiding the use of splints and taping for prevention of finger spasticity or contractures after stroke, as sensory recovery occurs through active motor rehabilitation, not through passive sensory stimulation alone 7, 8
