Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
This study aims to directly compare the acute effects of mirror therapy and VR therapy on upper limb motor function in hemiplegic patients. Forty-two participants aged 18-75 with hemiplegia due to stroke (6-12 months post-stroke) will be randomly assigned to either mirror therapy or VR therapy. The evaluation includes motor function (Fugl-Meyer Assessment), spasticity (Modified Ashworth Scale), activities of daily living (Barthel Index), fine motor skills (Box and Block Test), proprioception, and reaction time.
The goal is to identify the effectiveness of the mirror therapy and VR therapy on motor function, spasticity control, proprioception, daily activity performance, and reaction times, contributing valuable insights to clinical rehabilitation practices.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Group A : Mirror Therapy Protocol: Participants will be seated comfortably in a stable and ergonomically supportive chair. A mirror measuring approximately 40 cm by 50 cm will be strategically positioned along the mid-sagittal plane, effectively reflecting the unaffected limb and creating the visual illusion of bilateral symmetrical movements. This visual feedback aims to activate motor-related cortical regions within the affected hemisphere, thus enhancing immediate functional motor improvements. Participants will engage in structured therapeutic exercises, each carefully designed to target various aspects of upper limb motor function:
* Reaching Task: Participants will perform reaching movements towards standardized objects positioned at varying distances and spatial orientations. They will complete 3 sets of 10 repetitions, progressively challenging their spatial accuracy, visual-motor integration, and motor planning skills.
* Joint Range Movements: Participants will execute comprehensive movements involving finger flexion-extension, wrist flexion-extension, elbow flexion-extension, and shoulder flexion-abduction. Each movement will be repeated 10 times, systematically activating multiple joints and muscles to promote functional range of motion and coordination.
* Grasp and Release Exercises: Participants will complete grasping and releasing tasks with objects of different sizes, textures, and weights. This task includes 3 sets of 10 repetitions designed to enhance tactile feedback, grip strength, fine motor coordination, and functional hand dexterity.
Group B: Virtual Reality (VR) Therapy: Participants in the VR group will utilize advanced virtual reality equipment, including high-resolution VR headsets and handheld controllers, immersing themselves in an interactive, three-dimensional virtual environment. This environment is specifically developed to simulate realistic and engaging scenarios, enhancing ecological validity, motivation, and patient engagement through multisensory stimulation. Therapeutic tasks in the VR environment will mirror those in the mirror therapy protocol to facilitate direct comparative analysis:
* Virtual Reaching Tasks: Participants will perform interactive tasks, engaging in accurate reaching movements toward virtual targets displayed at various locations and distances within the virtual environment, emphasizing hand-eye coordination and spatial orientation.
* Virtual Joint Movements: Virtual tasks will guide participants through movements involving finger flexion-extension, wrist flexion-extension, elbow flexion-extension, and shoulder flexion-abduction. Visual and auditory cues in the VR environment will enhance proprioceptive feedback and facilitate precise motor execution.
* Virtual Grasp and Release Tasks: Participants will virtually grasp and manipulate various digital objects, practicing controlled grasp and release movements that mimic real-world functional tasks. Task complexity will vary to address different aspects of motor control, strength, and dexterity.
Assessment Methods: Objective and reliable clinical assessments will be conducted immediately before and after each therapy session to measure changes in motor function, muscle tone, sensory-motor integration, and functional independence. The assessments will include:
* Motor Performance: Evaluated by the Fugl-Meyer Motor Assessment (FMA), providing comprehensive data on upper limb motor function.
* Spasticity: Quantified using the Modified Ashworth Scale (MAS), providing reliable measurements of muscle tone.
* Activities of Daily Living (ADL): Assessed with the Barthel Index to objectively measure functional independence and performance in daily activities.
* Fine Motor Skills: Evaluated using the Box and Block Test, offering precise measurement of hand dexterity and coordination.
* Proprioception: Evaluated using standardized joint position matching tasks, assessing sensory-motor integration and proprioceptive accuracy.
* Reaction Time: Assessed via computerized Simple Reaction Time (SRT) testing, precisely measuring sensorimotor responsiveness and processing speed.
This multidimensional assessment approach ensures a detailed evaluation of the acute therapeutic impacts of each intervention. By systematically comparing the immediate effectiveness and therapeutic advantages of mirror therapy and virtual reality therapy, this study aims to generate evidence-based recommendations, contributing significantly to clinical decision-making processes and potentially optimizing rehabilitation strategies for individuals recovering from stroke-related hemiplegia.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Group A
Mirror Therapy
Mirror Therapy will be applied to the affected upper extremity of hemiplegic patients by placing a mirror in the midsagittal plane, reflecting movements of the non-paretic limb to create the illusion that both limbs are moving symmetrically. Each session will include task-specific, functional hand and arm movements (e.g., grasping, wrist flexion/extension) performed for 30 minutes. Patients will be instructed to focus on the mirror image while actively engaging in the exercises.
Group B
Virtual Reality (VR) Therapy
Virtual Reality (VR) therapy will consist of a single 30-minute immersive session designed to engage the upper extremity of hemiplegic patients. Participants will wear a VR headset and interact with a virtual environment using motion-tracking controllers. Activities are task-oriented and aim to stimulate functional movement through simulated real-life scenarios (e.g., reaching, grabbing, stacking). This intervention offers multisensory feedback and high user engagement.
