Effect of Transcutaneous Auricular Nerve Stimulation vs Body Rocking Exercises on Spasticity of Upper Limb

The TANS Group will receive low-frequency electrical stimulation (20-30 Hz) via a TENS device on the auricular vagus nerve for 30 minutes, 3-4 times per week for 8 weeks. This non-invasive therapy aims to reduce spasticity, enhance neuroplasticity, and improve motor function and independence, assessed through standardized scales.

Group 2: Body Rocking Exercise Group Participants will perform rhythmic body rocking exercises for 20-30 minutes, 3-4 times per week for 8 weeks to reduce spasticity and improve motor coordination. Group 3: Control Group (Usual Rehabilitation) Participants will receive standard stroke rehabilitation (therapy, stretching, functional training) for 20-30 minutes, 3-4 times per week for 8 weeks as a baseline comparison.
