RESUMEN
OBJECTIVES: Taxi drivers experience chronic neck pain owing to their posture while driving. The aim of this study was to investigate the effect of self-stretching exercises with kinesio taping on pain, stress, pressure pain threshold (PPT), disability, cervical range of motion (CROM) in this population. DESIGN: A single-blind, randomized controlled trial SETTING: Forty-three taxi drivers with nonspecific chronic nonspecific neck pain were randomly assigned to experimental (n = 22) and control (n = 21) groups. METHODS: In the experimental group, self-stretching exercises were performed 3 times a day, 5 days per week, for 4 weeks, with kinesio taping applied while driving. In the control group, only kinesio taping was applied while driving for 4 weeks. Pain intensity, stress intensity, PPT, neck disability, and CROM were assessed pre-intervention, post-intervention, and at 4 weeks post-intervention. RESULTS: Significant time and group interactions were observed in pain intensity at rest (p = 0.048) and while driving (p = 0.001). In the experimental group, the Pre - Post - Follow-up mean (95% CI) was 4.41 (4.14 to 4.68) - 3.82 (3.57 to 4.07) - 3.78 (3.55 to 3.99). In the control group, the Pre - Post - Follow-up mean (95% CI) was 4.29 (4.01 to 4.56) - 3.86 (3.60 to 4.11) - 4.05 (3.82 to 4.27) for pain at rest. In the experimental group, the Pre - Post - Follow-up mean (95% CI) was 4.91 (4.63 to 5.19) - 4.00 (3.76 to 4.24) - 3.69 (3.69 to 4.22), while in the control group, the Pre - Post - Follow-up mean (95% CI) was 4.81 (4.53 to 5.09) - 4.38 (4.13 to 4.63) - 4.57 (4.30 to 4.85) for pain while driving. PPT on the right (p = 0.029) and left (p < 0.001) sides, and neck disability (p = 0.001) also showed significant time and group interactions. NDI was not clinically significant based on the minimum clinically important difference. All CROM showed significant time and group interactions (flexion, p = 0.008; right lateral flexion, p = 0.009; left lateral flexion, p = 0.004; right rotation, p = 0.001; left rotation, p = 0.001), except for extension. CONCLUSION: This study showed that self-stretching exercises with kinesio taping provided benefits over kinesio taping alone on pain intensity, PPT, disability, and CROM in taxi drivers with nonspecific chronic neck pain. CLINICAL TRIAL REGISTRATION: This study registered with the Clinical Research Information Service (WHO International Clinical Trials Registry Platform) on September 22, 2020 (KCT0005406).
