| Abstract | ||
| Background: Hemiparesis impairs motor function in the upper limbs, affecting a large proportion of stroke survivors and leading to chronic disability. This results in difficulty performing activities of daily living, limits social participation, and negatively impacts quality of life. Purpose: This study aimed to evaluate the effectiveness of kinesthetic illusion by visual stimulation (KINVIS) on upper limb motor function in patients with hemiparesis. Methods: Kinesthetic illusion was induced using a video showing finger extension (KINVIS), combined with electrical stimulation of the finger extensor muscles to enhance proprioception. Transcranial direct current stimulation (tDCS) was applied simultaneously, with the anode placed over the motor cortex and the cathode over the shoulder joint, for 20 minutes per session. Twenty participants with severe upper limb paralysis and inability to extend their fingers received one KINVIS session per week in addition to traditional physical therapy for two weeks. Functional outcomes were assessed using the Fugl-Meyer Assessment (FMA), Modified Ashworth Scale (MAS), and Motor Activity Log (MAL) before and after the intervention. Results: No significant between-group differences were observed. However, within-group analysis revealed significant improvements in FMA, MAS, and MAL scores following the two-week intervention period. Conclusion: Although KINVIS is a passive intervention, its short-term application led to meaningful improvements in motor function and kinesthetic perception in patients with hemiparesis. These findings suggest that KINVIS may enhance motor imagery and promote motor recovery when used adjunctively with conventional therapy. | ||
