Objective:
To assess the effectiveness of soft splints on spasticity and hand opening in chronic patients with upper limb spasticity and disorders of consciousness (vegetative state/unresponsive wakefulness syndrome-VS/UWS and minimally conscious state-MCS).
Methods:
In this prospective single-blind controlled trial, a blind evaluator assessed spasticity (Modified Ashworth Scale and Modified Tardieu Scale), range of motion (ROM) at the metacarpophalangeal, wrist and elbow joints and the patients' hand opening before and after soft splinting, manual stretching and a control condition (i.e. no treatment), as well as 60 minutes later.
Subjects:
Seventeen patients with chronic (>3 months) disorders of consciousness were included (five VS/UWS; seven women; mean age = 42 ± 12 years; time since insult = 35 ± 31 months). Patients received either passive splinting, manual stretching treatment or no treatment.
Results:
Thirty minutes of soft splinting or 30 minutes of manual stretching both improved spasticity of the finger flexors. An increase of hand opening ability was observed after 30 minutes of soft splinting.
Conclusion:
Thirty minutes of soft splint application reduces spasticity and improves hand opening of patients with chronic disorders of consciousness. Soft splinting is well tolerated and does not require supervision.
