Participants in this group will receive a standard physical therapy program including range of motion exercise, electrical muscle stimulation, and Mental practice with motor imagery and stretching exercise, isolated muscle facilitation using electromyography (EMG) biofeedback for six weeks, followed by task-oriented training ofthe upper limb for six weeks

Participants in this group will receive a standard physical therapy program, including a range of motion exercise, electrical muscle stimulation, Mental practice with motor imagery, and stretching exercise, synergetic muscle facilitation for six weeks, and followed by task-oriented training of the upper limb for six weeks

• Soft tissue technique (stretch) will be applied for the anterior pectoral region, elbow flexors, pronators, wrist flexors, and finger flexors(for both research groups.
• Passive Range of motion exercises will be applied for the glenohumeral joint, scapulothoracic articulation, elbow joint, radioulnar joint, and wrist joint(for both research groups).
• Muscular electrical stimulation will be applied for supraspinatus, anterior and posterior deltoid, biceps and triceps, pronators and supinators, wrist and finger extensors, and finally the lumbricals (Each muscle group 20 min) (for both research groups).

In mental practice, the patient adheres to a set of imagined task performances ( picking up a cup) or movements (reaching out with the arm).

- Action Reach Arm Test (ARAT): It will be used to assess upper extremity performance (coordination, dexterity, and functioning). It is a 19-item observational measure. Items are categorized into four subscales (grasp, grip, pinch, and gross movement) and arranged in order of decreasing difficulty. Subjects are first asked to perform the most difficult task within a subscale, followed by the least difficult task. while scoring the individual based on their performance of each task

-Required Equipment: Chair without armrests, Table, Wooden blocks of various sizes, Cricket ball, Sharpening stone, Alloy tubes, Washer and bolt, 2 glasses Sharpening stone, Marbles, Ball bearings, and a Tin lid.

-scoring: Task performance is rated on a 4-point scale, ranging from 0 (no movement) to 3 (movement performed normally). Scores on the ARAT may range from 0 to 57 points, with a maximum score of 57 indicating better performance.

Kinovea is a valid, precise, and reliable computer program for measuring angles and distances. Kinovia software will be used to analyze the kinematics (Position and acceleration speed)of the shoulder, elbow, and wrist. while patients perform the subscales of the Action Reach Arm Test.

• Instrumentation: Digital video camera and Computer equipment for the measurement process.
• procedure: All participants were instructed to wear light clothes for the determination of the selected bony landmarks and to allow easy forward reaching motion. An adhesive marker dot will be placed on preselected anatomical landmarks like the acromion, lateral epicondyle, and wrist (ulnar styloid/mid-forearm) to measure joint angles (shoulder, elbow, wrist) and movement speed. Then, patients will be asked to perform the subscales of the Action Reach Arm Test, such as reaching and grasping. Patients will be captured while performing these tasks using video camera and will be analyzed using Kinovia program.
