This randomized clinical trial aims to compare the effectiveness of Transcutaneous Electrical Nerve Stimulation (TENS) and therapeutic ultrasound, both combined with therapeutic exercises, in the management of mechanical neck pain. A total of 44 participants male and female both with mechanical neck pain will be randomly allocated into two equal groups at the physiotherapy OPD of DOW Institute of Physical Medicine \& Rehabilitation, Dow University of Health Sciences, Karachi. Group A will receive TENS with exercise, while group B will receive ultrasound with the same exercise protocol. Both groups will receive 9 treatment sessions over 2 weeks. Outcomes will include pain intensity, functional disability, and cervical range of motion, assessed before and after the intervention.
