Efficacy of TECAR Therapy on Patient With Mechanical Neck Pain

The goal of this clinical trial is to evaluate the effectiveness of TECAR therapy in improving pain intensity, cervical range of motion, and functional disability in individuals with mechanical neck pain. It will also assess whether TECAR therapy provides additional clinical benefits compared with conventional physical therapy treatment. The main questions it aims to answer are: * Does TECAR therapy reduce pain intensity in patients with mechanical neck pain? * Does TECAR therapy improve cervical range of motion (CROM)? * Does TECAR therapy reduce functional disability as measured by the Neck Disability Index (NDI)? Researchers will compare participants receiving TECAR therapy combined with conventional physical therapy to participants receiving conventional physical therapy alone to determine the effectiveness of TECAR therapy in managing mechanical neck pain. Participants will: * Attend scheduled treatment sessions during the study period * Receive either TECAR therapy with conventional physical therapy or conventional physical therapy alone * Undergo assessment of pain intensity, cervical range of motion, and neck disability before and after treatment

Inclusion Criteria: * Presence of neck pain for at least 3 months * Limited cervical range of motion associated with neck pain * Ability to understand and follow study instructions Willingness to participate and sign the informed consent form Exclusion Criteria: * History of cervical spine surgery or fracture * Cervical radiculopathy or other neurological disorders * Presence of inflammatory, rheumatic, or systemic diseases affecting the cervical spine Severe cervical disc prolapse or spinal instability Current participation in another treatment program for neck pain Pregnancy Presence of pacemakers, metal implants, or contraindications to TECAR therapy Skin disorders or open wounds in the treatment area
