Effects of oscillatory mobilization as compared to sustained stretch mobilization in the management of cervical radiculopathy: A randomized controlled trial

Abstract

BACKGROUND:

Cervical radiculopathy is a relatively common musculoskeletal disorder resulting in a significant social and occupational impact. Manual therapy is thought to provide relief in cervical radiculopathy; however, evidence is lacking regarding the comparison of different manual therapy concepts.

OBJECTIVE:

To determine the effects of Maitland’s oscillatory mobilization as compared to Kaltenborn’s sustained stretch mobilization in the management of cervical radiculopathy.

METHODS:

A randomized controlled trial was conducted at Fauji Foundation Hospital comprising of 46 patients randomized into oscillatory and sustained stretch mobilization groups. Numeric Pain Rating Scale (NPRS), Neck Disability Index (NDI) and cervical range of motion (ROM) were used as outcome variables.

RESULTS:

No significant differences were observed at base line between the two groups ( $P>$ 0.05) except for ROM in extension and left side bending ( $P<$ 0.05). In terms of pre and post treatment comparison, P value of less than 0.05 was observed for both groups, indicating both treatments to be effective in isolation. However, post treatment comparison between both groups showed oscillatory mobilization to be superior to sustained stretch mobilization ( $P<$ 0.05) in the management of cervical radiculopathy except for the outcomes of pain and side bending.

CONCLUSION:

Both oscillatory and sustained stretch mobilization techniques are found to be effective in the management of cervical radiculopathy in terms of pain, range and disability. However, oscillatory mobilization is found to be superior in terms of functional ability and range of motion.
