Visually Induced Kinaesthetic Illusion Combined with Therapeutic Exercise for Patients with Chronic Stroke: A Pilot Study.

Abstract

ObjectiveKinaesthetic perceptional illusion by visual stimulation (KINVIS) combined with neuromuscular electrical stimulation (NMES) and conventional therapeutic exercise (TherEX) has been shown previously to enhance motor function in stroke patients with chronic hemiparesis. The aim of this preliminary study is to assess the effects of a repetitive KINVIS intervention combined with TherEX, but without NMES, on upper limb motor function of patients with stroke-induced hemiparesis.DesignA quasi-experimental study, with pretest–posttest for 1 groupPatientsTen patients with stroke-induced, chronic, severe upper limb hemiparesis.MethodsPatients were evaluated before and after a 10-day intervention, during which KINVIS and TherEX were applied for 20 and 60 min, respectively, for 5 days per week (Monday to Friday). Upper limb motor function was assessed using Fugl-Meyer Assessment (FMA) and Action Research Arm Test (ARAT), and resistance to passive movement in flexor muscles was assessed using the Modified Ashworth Scale (MAS). In addition, the amount of use and quality of movement of the affected upper limb in daily life were assessed using Motor Activity Log (MAL).ResultsClinical assessments with FMA, ARAT, MAS, and MAL significantly improved after the intervention period.ConclusionA repetitive KINVIS intervention combined with TherEX may improve upper limb motor function in patients with chronic stroke and severe hemiparesis.LAY ABSTRACTKinaesthetic perceptional illusion by visual stimulation (KINVIS) combined with neuromuscular electrical stimulation (NMES) and a conventional therapeutic exercise (TherEX) enhance muscle use in stroke patients with chronic paralysis. This preliminary study assessed the effects of a repetitive KINVIS intervention with added TherEX, but without NMES, on the use of the arm in Ten patients with stroke-induced paralysis. Ten patients with stroke-induced chronic paralysis were evaluated before and after a 10-day intervention, during which KINVIS and TherEX were applied for 20 and 60 min, respectively, for 5 days per week (Monday to Friday). The use of the paralysed arm improved significantly after the intervention. The repetitive KINVIS intervention combined with TherEX may improve the use of the arm in patients with chronic paralysis due to stroke.
