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 training will be performed using a pressure biofeedback unit to facilitate selective activation and improve the strength and endurance of the deep cervical flexor muscles, particularly the longus colli and longus capitis. The participant will be positioned in supine lying with the hips and knees comfortably flexed, and the pressure biofeedback cuff will be placed beneath the cervical spine at approximately the C4-C5 level. The cuff will be inflated to a baseline pressure of 20 mmHg. The participant will be instructed to perform a gentle cranio-cervical flexion movement by slowly nodding the head and drawing the chin inward while maintaining contact of the head with the treatment surface. The pressure will be gradually increased to the prescribed target while avoiding head lifting, excessive cervical flexion, jaw clenching, shoulder elevation, or compensatory activation of the superficial cervical muscles. The target pressure will be 22 mmHg during the first week, 2

• 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 to improve scapular control, postural alignment, and the strength and endurance of the scapular stabilizing muscles. During the first week, scapular retraction and depression exercises will be performed in sitting for 3 sets of 10 repetitions with a 5-second hold and 60 seconds rest between sets. During the second week, scapular retraction will be progressed using light TheraBand resistance for 3 sets of 10 repetitions with controlled movement and 60 seconds rest between sets. During the third week, wall slides and prone Y and T raises will be introduced and performed for 3 sets of 8-10 repetitions with controlled movement and 30-60 seconds rest between sets. During the fourth week, scapular stabilization exercises will be progressed with shoulder flexion and abduction while maintaining appropriate scapular control, performed for 3 sets of 10 repetitions with 30-60 seconds rest between sets. All exercises will be performe

• 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.
