Effects of IASTM and Vibration Therapy in Cervical Disc Herniation

Participants in this group will receive percussion-based vibration therapy applied using a percussion massage device (Compex Fix 2.0) with a soft head attachment. Therapy will target trapezius, levator scapula, and cervical paravertebral muscles along their origin-insertion lines for 3 minutes per muscle group.

Participants will receive instrument-assisted soft tissue mobilization applied using specially designed stainless-steel instruments. Techniques (Sweep, Fan, Brush) will be applied to cervical and upper-back musculature (splenius, suboccipital, upper-middle-lower trapezius) and related fascia between C1-T1 vertebrae, parallel to muscle fibers for approximately 6 minutes per session. Each technique will consist of 8-10 repetitions.

Participants in this control group will receive conventional physiotherapy treatment alone. The treatment includes heat therapy applied to the cervical region for 20 minutes, TENS application at a frequency of 100 Hz to painful areas, ROM exercises performed in all cervical directions (2 sets of 10 repetitions, 2-second holds at end-range), and isometric strengthening exercises in cervical flexion, extension, and lateral flexion directions (2 sets of 10 repetitions, 6-second holds per repetition). Sessions will take place 4 days per week for 3 weeks.
