Abstract

This study investigated the effectiveness of Kendall exercise with and without EMG biofeedback on individuals with forwarding head posture (FHP). Thirty (30) adult males with FHP who volunteered to participate in this study were randomly distributed into the Kendall exercise group (KE), Kendall exercise - EMG biofeedback group (KEEB), and the control group. The exercises were carried out two sessions a week for 6weeks. We measured cranial vertebral angle (CVA) and cranial rotation angle (CRA) before and after the intervention. Data were analyzed using paired t-tests and one-way ANOVA. After the 6weeks of intervention, we observed that Kendall exercise improved both CVA and CRA in both the KE group and the KEEB group. Significant differences were observed between the KE group and the control group in CVA and CRA(p<0.05). We also found significant differences between the KEEB group and the control group in CVA and CRA(p<0.05). However, no significant differences were observed between the KE group and the KEEB group in all outcomes (p>0.05). With the present findings, we can affirm that Kendall’s exercise with or without EMG biofeedback can be effective for improving head posture in individuals with FHP
