Abstract
Various approaches to stroke rehabilitation, such as facilitation techniques including proprioceptive neuromuscural facilitation techniques (PNF), Brunnstrom's approach, and Bobath's approach, have been studied to improve the functional recovery of hemiplegia due to brain damage. However, there is some controversy surrounding these facilitation techniques with regard to their efficacy in stroke rehabilitation. Specifically, there is insufficient evidence that these techniques are superior to conventional exercise therapies.
Recent studies have shown that brain plasticity results in functional recovery in humans. Recovery depends on the plasticity of the synapse, and changes in the strength of a synapse are controlled by a basic mechanism:An increase in synaptic efficacy arises from the repeated stimulation of the postsynaptic cell by the presynaptic cell. The basic theory of repetitive facilitation exercises (RFE) using novel facilitation methods for the hemiplegic limb mainly aim to strengthen the neuronal circuits through the injured descending motor tracts by repetition of the movements that are to be recovered. The patient's intentions to move the hemiplegic limb are realized by using multiple sensory stimulations to target the neural circuits related to each movement. The effects of RFE on the functional recovery of hemiplegic limbs have been confirmed by scientific studies.
Combined therapy using vibratory or electrical stimulation might promote efficacy of RFEs for patients with hemiplegia.
