This study will investigate whether adding electromagnetic field therapy (EMT) to a standard physical therapy program is more effective than physical therapy alone for improving balance and walking ability in paraparetic patients. Thirty patients with paraparesis (weakness in the lower limbs) due to spinal cord lesions between levels T6 and T12 will be randomly assigned to one of two groups. Both groups will receive a 45-minute physical therapy session, three times per week for two months. The physical therapy program will include stretching, strengthening, balance, and gait training exercises. The key difference will be that one group (Group II) will also receive active low-frequency (0.5 Hz) electromagnetic therapy applied to their spine during their sessions, while the other group (Group I) will receive a placebo (inactive) EMT device. Patients will be assessed before and after the 2-month treatment period. The assessments will measure muscle spasticity (using the Modified Ashworth Scale), balance (using the Biodex Balance System), and detailed gait parameters like step length, stride length, and base of support (using a 3D motion analysis system
