Prognosis prediction of the effect of botulinum toxin therapy and intensive rehabilitation on the upper arm function in post-stroke patients using hierarchical cluster analysis

In this study, BoNT-A and intensive rehabilitation showed improvement in spasticity and UL function. A high therapeutic effect is expected in patients with moderate impairment levels who have voluntary movement in whole UL or in UL except for the wrist.IMPLICATIONS FOR REHABILITATIONHierarchical cluster analysis focusing on the Fugl-Meyer Assessment of the Upper Extremity sub-categories may be useful for studies aimed to improve the upper arm function.Botulinum Neurotoxin A therapy (BoNT-A) and intensive rehabilitation in post-stroke patients showed improvement in spasticity and upper arm function.The degree of the upper arm function before the intervention may affect the improvement effect of BoNT-A and intensive rehabilitation.In the motor function, the post-stroke patients with a moderate impairment level who have voluntary movement of the whole upper limb or upper limb except for the wrist are most likely to receive these therapeutic effects.
