Gait training in hemiplegia

Abstract

Restoration of gait is a major goal in neurological rehabilitation. Before starting therapy, a comprehensive assessment is necessary to evaluate the deficits and remaining functions. A wide variety of therapeutic procedures are available and have to be adapted to the individual situation - different concepts of physiotherapy stress different features like: force exercise, reduction of spasticity, gait symmetry, utilization of equilibrium reflexes, stepping automation, endurance training, repetition of rhythmic movements, etc. The spectrum of available therapies was recently widened by treadmill training, with partial body-weight support, locomotor pharmacotherapy, selective reduction of spasticity by botulinum toxin injections, and by musical biofeedback, which have each proved to be successful in the restoration of gait pattern. Treadmill training based on partial body weight support, combined with enforced stepping movements has proved to be successful in the restoration of gait pattern. A common problem in hemiparetic gait, is the spastic inversion of the foot. If spasticity is not severe, an ankle-foot orthosis (AFO) is the appropriate technical aid. In other cases, botulinum toxin injection into spastic leg muscles has been successfully used to improve gait functions. In hemiparetic stroke patients, auditory (musical) rhythm, as a peripheral pacing signal, resulted in a significant increase in weight-bearing stance time on the paretic side. In addition, there was an improved stride symmetry with rhythmic cueing and a normalizations of gait pattern. These methods directed to gait improvement should be combined and adapted to the individual patient's needs, in order to obtain the best results.
