Effects of Cervical Mobilization on Balance and Proprioception in Patients With Nonspecific Neck Pain

Abstract

ObjectiveThis study investigates the effect of cervical mobilization on balance and cervical proprioception in patients with nonspecific neck pain. MethodsA prospective, double-blind, randomized clinical trial was conducted involving a 3-week treatment protocol for which 66 patients were randomly assigned to 2 groups. Both groups underwent conventional physiotherapy (hot pack and transcutaneous electrical nerve stimulation) twice a week for 3 weeks along with additional cervical mobilization in the mobilization group, and sham mobilization in the sham control group. Static and dynamic balance, cervical proprioception, cervical mobility, and pain intensity were evaluated using a Kinesthetic Skill Training System 3000 device, the “Joint Position Error Test,” Cervical Range-of-Motion Instrument, and the visual analog scale, respectively. ResultsAfter treatment, significant improvements were noted in dynamic balance, mobility, pain intensity (P < .001, P < .001, P < .001, respectively), and proprioception in the left direction of rotation in the mobilization group (P = .003) that were significantly greater than those observed in the sham mobilization group (P < .001, P < .001, P < .001, P = .003, respectively). Although a significant decrease was observed in the deficits of static balance (P = .044) and proprioception in the right direction of rotation (P = .011) after mobilization, the changes were similar in both the mobilization and sham mobilization groups (P = .192, P = .154, respectively). ConclusionCervical mobilization led to significant improvements in dynamic balance, pain intensity, mobility, and partial improvements to proprioception in a comparison with a sham mobilization group, while the effect on static balance was not significant.
