Effectiveness of Pressure Biofeedback-Assisted Deep Cervical Flexor Training With and Without Scapular Stabilization Exercises on Pain, Range of Motion and Neck Disability in Cervical Spondylosis

Trial design

Treatments tested in this trial

• Pressure Biofeedback-Assisted Deep Cervical Flexor Training

  Other intervention Other interventionAn intervention that does not fit one of the standard intervention types.

  Deep cervical flexor (DCF) training will be performed using a pressure biofeedback unit to facilitate selective activation of the longus colli and longus capitis. Participants will lie supine with hips and knees flexed, with the cuff placed beneath the cervical spine at C4-C5 and inflated to a baseline pressure of 20 mmHg. Gentle cranio-cervical flexion will be performed by nodding and drawing the chin inward while maintaining head contact with the surface and avoiding compensatory superficial muscle activation. Target pressure will progress from 22 mmHg in Week 1 to 24, 26, and 28 mmHg in Weeks 2-4, respectively. Training will consist of 3 sets of 10 repetitions, with 5-second holds in Week 1 progressing to 10-second holds thereafter and 30-60 seconds of rest between sets. Arm lifts will be added in Week 3 and leg marching in Week 4. The intervention will be administered three times weekly for four consecutive weeks.

• Scapular Stabilization Exercises

  Other intervention Other interventionAn intervention that does not fit one of the standard intervention types.

  Scapular stabilization exercises will be performed progressively for 4 weeks to improve scapular control, alignment, and stabilizer strength. In Week 1, seated scapular retraction and depression will be performed for 3 sets of 10 repetitions with 5-second holds and 60 seconds rest. In Week 2, scapular retraction will progress using light TheraBand resistance for 3 sets of 10 repetitions with controlled movement. In Week 3, wall slides and prone Y and T raises will be performed for 3 sets of 8-10 repetitions. In Week 4, scapular stabilization with shoulder flexion and abduction will be performed for 3 sets of 10 repetitions. All exercises will emphasize controlled movement, neutral alignment, and avoidance of compensatory shoulder or trunk movements. Sessions will be conducted three times weekly.

• Standard Physiotherapy

  Other intervention Other interventionAn intervention that does not fit one of the standard intervention types.

  Standard physiotherapy will include therapeutic exercises and postural management techniques aimed at reducing pain, improving cervical mobility, flexibility, and functional performance. Cervical range-of-motion exercises including flexion, extension, lateral flexion, and rotation will be performed within a pain-free range for 10 repetitions in each direction. Stretching exercises for the upper trapezius, levator scapulae, and pectoral muscles will be performed for 20-30 seconds for 3 repetitions. Cervical isometric strengthening exercises including flexion, extension, and lateral flexion will be performed with a 5-10-second hold for 10 repetitions. Postural education and ergonomic advice will also be provided, including instructions regarding proper sitting posture, appropriate head and neck positioning, and avoidance of prolonged static postures. Standard physiotherapy will be provided for approximately 10-15 minutes per session, three times weekly for four consecutive weeks.
