Background and purpose-GMI is a dynamic state during which the representation of a specific motor action is internally reactivated within working memory without any overt motor output. The imagery of movement activates largely the same brain areas that are activated when movement is actually performed. Motor impairment after stroke is a major cause of permanent disability. Recovery of the upper extremity is crucial in order to perform activities of daily living but is often variable and incomplete. It is proven that prolonged passive movement therapy in stroke patients neither improves performance nor induces cortical plasticity. And an early initiation of active movement becomes difficult due to lack of motor performance. Graded motor imagery (GMI) can be used to bridge this gap between passive therapy and active therapy. The method-a descriptive case study was carried out on two patients screened from the community and selected through purposive sampling. They were given graded motor imagery (GMI) for 5 days a week for 4 weeks 60 minutes per session along with conventional therapy for 30 minutes. The outcome measures were Fugl Meyer assessment of sensorimotor function after stroke (FMA) and The Chedoke arm and hand activity inventory (CAHAI) which were administered to the patient before and after the intervention period of 4 weeks. Result-for FMA the one-tailed p-value is 0.0155 which is statistically significant at 95% confidence interval. For CAHAI the one-tailed p-value is 0.0155 which is statistically significant at 95% confidence interval. Discussion- GMI is known to stimulate the premotor area, supplementary motor area, cingulate area and parietal cortical area as well as basal ganglia and cerebellum by inducing cortical plasticity leading to improvement in motor function which goes in accordance with our result. Conclusion-upper extremity function shows significant improvement after graded motor imagery along with conventional therapy on FMA Scale and CAHAI scale.
