Stroke is focal neurological disorder that occurs due to the compromised blood flow to the brain. It results in mobility deficit, functional and gait impairment. Multiple rehabilitation methods have been designed and used, motor imagery (MI) and virtual reality (VR) are among the emerging techniques that are being used for the rehabilitation of patients with neurological conditions that improve motor learning through explicit and implicit processes.~After stroke the residual symptoms such as muscle hyper tonicity, attention deficiency, hemi neglect, abnormal reflexes and sensorimotor functional impairment may persist. Additional to these neurological symptoms certain balance issues may cause decrease in proprioception, muscle strength, increased load on non-paretic extremity and postural oscillations. It has been reported that every year approximately 25.7 million people survive stroke attacks, 6.5 million die because of stroke and 113 million people have disability-adjusted life-years.~Kinect based rehabilitation and virtual feedback have shown relevant activation changes in the primary sensorimotor cortex and can be responsible for that part of brain reorganization for improving in upper limb in stroke patients. Use of exer gaming is one of the emerging technologies that are being used for the physical, cognitive and motor rehabilitation of stroke patients. It is combination of video games and motion sensors incorporated in a virtual reality environment that engage the patients and improves motor learning therefore activating the motor areas of the brain for long term results.~Non immersive virtual reality gaming has been used for improving balance among the stroke patients. Not only is it considered more beneficial as compared to the conventional therapies but also maintains the interest of patients in their rehabilitation protocol. The Kinect based games use sensors that catch movements of the patients and they are able to watch them in real time with immediate feedback that becomes a source of motivation for them.~Xbox Kinect virtual gaming creates 3D environment with sensors and requires no controllers for patients to perform exercise whereas motor imagery is a state in which a particular motor action is internally activated without any motor output. Not only is VR and MI training motivating as compare to conventional therapies but also provide positive learning experience and neuroplasticity. With xbox kinect based VR therapies and MI, the exercise plan is tailored according to the needs of the patient.~It will be a single blinded randomized control trial in which control group will be given conventional physiotherapy protocol for 30 minutes and experimental group will receive the VR and MI training with conventional treatment for a total 60 minutes, 3 days a week for 6 weeks. Motor function will be assessed by fugl-meyer scale (LE), dynamic mobility by berg balance scale and 6 minute walk test, quality of life by barthel index and gait with dynamic gait index. Patient will be assessed at baseline and at the end of six weeks. The data will be analyzed using SPSS 25 software.
As virtual reality has therapeutic benefits and improves motor learning by practicing exercises in environment that analogue and mimic occasions and events of real world, as VR is designed and tailored according to the need of patient so it may address the individual issues whereas motor imagery uses explicit learning process for muscle activation and movement. Therefore their combination may yield better outcomes in terms of lower limb function and dynamic mobility, so there is a need to assess the combined effects of Xbox kinect gaming with motor imagery in chronic stroke patients.
