BackgroundTreatment of movement faults in the neck is known as an important factor in treatment of chronic neck pain. Along with the identification of site and direction of the faults, direction-movement control intervention retrains the control of the movement faults.PurposeThis study was designed to investigate long-term effects of a direction-movement control training on pain, disability, head repositioning accuracy, function, cervical flexor endurance, and range of motion in female patients with chronic nonspecific neck pain.Material And MethodsThirty women (36.5 ± 5.7 years) with chronic nonspecific neck pain were randomly allocated into two groups, i.e., an experimental group (n = 15) and a control group (n = 15). The experimental group performed the direction-movement control training for 30 min/day, three days per week for six months. All subjects were evaluated using the visual analog scale (VAS), range of motion (TOM), progressive iso-inertial lifting evaluation (PILE), neck disability Index (NDI), helmet attached with laser pointer using for head repositioning accuracy (HRA), and Trott's test (deep neck flexor endurance), in pre- and six-months post-treatment intervention.ResultsSignificant differences were observed for the pain, neck disability Index, function endurance, head repositioning accuracy, range of motion, and cervical flexor endurance in the experimental group compared to that of control group.ConclusionDirection-movement control training is likely to be an effective training program to enhance body functionality through improvement of pain, function, endurance, head repositioning accuracy, range of motion, and cervical flexor endurance. Due to the high reported effect size for direction-movement control exercises, the application of the training is suggested as a supplementary method to improve chronic nonspecific neck pain in females.Copyright © 2017 Elsevier Ltd.
