Effect of Kinetic Control Training on Flexion Relaxation Phenomenon and Craniovertebral Angle in Cervical Radiculopathy Patients

The conventional physical therapy program will be received for 8 weeks by the two groups. It includes the application of moist heat using a hot pack for ten minutes, followed by continuous ultrasound therapy operated at a frequency of 1 MHz and an intensity of 1.5 W/cm² for five minutes. Transcutaneous Electrical Nerve Stimulation (TENS) will also be utilized, with its development and application based on the Gate Control Theory. TENS will be applied for twenty minutes, with electrodes positioned on either side of the neck at the level of pain, using a pulse rate ranging from 2 to 50 Hz.

The Kinetic Control Retraining Program will be received for 8 weeks by the experimental group. It focuses on addressing uncontrolled movement (UCM) and muscle synergy retraining. UCM retraining starts with patient education on movement deficiencies, their symptoms, and adherence to training. Movement coordination is retrained in test positions, progressing to challenging ones using feedback from mirrors, walls, or hands. Corrections focus on lower cervical flexion, upper cervical extension, mid-cervical translation/extension, side-bending, and rotation, emphasizing controlled dissociation in supported and unsupported postures. Muscle synergy retraining targets global stabilizers (e.g., deep neck flexors and extensors) and mobilizers (e.g., sternocleidomastoid and suboccipital muscles) to enhance coordination, stability, and motor control.
