Effects of Cervical Traction With and Without EMG Biofeedback in Patients With Cervical Radiculopathy

Cervical radiculopathy is a neurological condition which is caused by underlying musculoskeletal disorders including herniated disc and degenerative changes in cervical spine that results in narrowing or stenosis of intervertebral foramen. This narrowing leads to compression of nerve root at the respective foramen. The compressed nerve root produces symptoms like numbness, tingling, pain and motor weakness in neck and upper extremity. These symptoms appear at the dermatome and myotome distribution of the affected nerve root. Mostly the cervical radiculopathy is present unilaterally but in severe cases it can appear bilaterally where bony spurs are found at various levels and nerve root in under compression on both sides.

The annual incidence rate of cervical radiculopathy is reported to be 107.3 per 100,000 of men and 63.5 per 100,000 of women. So accordingly, the condition is more common in males than females. Although no definitive treatment plan for cervical radiculopathy has been developed, there is a general consensus in the literature that using manual therapy techniques in conjunction with therapeutic exercise is effective in terms of increasing function and active range of motion (AROM). The focus will most likely be on reducing pain and disability. Recent researches have shown that exercise therapy has the highest beneficial outcomes. Treatment options for rehabilitation plan includes: Education and advice, Manual Therapy - PAIVMs (Passive Accessory Intervertebral Movements) / PPIVMs (Passive Physiological Intervertebral Movements) / NAGs (Natural Apophyseal Glides) / SNAGs (Sustained Natural Apophyseal Glides),Exercise Therapy - AROM, stretching and strengthening and Postural re-education Cervical traction and electromyography (EMG) biofeedback have been administered by many physiotherapists and positive outcomes are revealed. Traction not only relives nerve root compression but also helps in managing acute pain instantly whereas EMG biofeedback is used to generate an electrical feedback signal in response to muscle activation and helps patients to learn a more effective way of using their weak muscles
