Effectiveness of tens versus interferential therapy in patients with cervical radiculopathy

Background: Cervical radiculopathy is a dysfunction of nerve root of the cervical spine where C6 & C7 nerve roots are the most commonly affected. It encompasses important symptoms other than pain, such as paresthesia, numbness and muscle weakness in dermatomal or myotomal distribution of an affected nerve root. A multitude of physical therapy interventions have been proposed to be effective in the management of cervical radiculopathy, including mechanical Interferential Therapy, manipulation, therapeutic exercises and TENS. Studies to find out the effectiveness of TENS versus Interferential Therapy among patients with Cervical Radiculopathy are sparse.Hence the present study was undertaken to find out and compare the effectiveness of TENS versus Interferential Therapy a newer technique towards betterment in treatment of cervical radiculopathy patients.Methodology: 30 patients from Century Super Speciality Hospital, Banajara Hills, Hyderabad. Were chosen based on the inclusion and exclusion criteria. Group A comprised of 15 people with cervical radiculopathy were given TENS with Isometric neck exercises and active neck movements. Group B comprised of 15 people with cervical radiculopathy were given Interferential Therapy with Isometric neck exercise and active neck movements. VAS Scale & Neck Disability Index (NDI) were used as outcome measures pre & post treatment.Results: The pre - test evaluation showed that, there is no significant difference (P> 0.05) between the two groups for all the variables measured. The post-test evaluation of both groups showed a very high significance (P< 0.05) within the group for all the outcome measurements. A post-test comparison of measured variables, between the groups showed that the Group A demonstrated a statistically significant (P< 0.05) reduction in pain and Neck Disability Index.Conclusion: From the above study concluded that TENS was more effective in the management of cervical radiculopathy along with isometric neck exercise, in reducing both neck & arm pain, neck disability & in improving activities of daily living.
