PURPOSE: Forward head posture (FHP) is a head-on-trunk malalignment that results in musculoskeletal dysfunction and neck pain. To improve forward head posture, both the craniocervical flexion exercise (CCFE) and the visual guide (VG) technique have been used. This study compared the immediate effects of CCFE and VG combined with CCFE on craniovertebral angle (CVA), as well as on the activity of the sternocleidomastoid (SCM) and anterior scalene (AS) muscles during CCFE in subjects with FHP. METHODS: In total, 16 subjects (nine males, seven females) with FHP were recruited using the G-power software. Each subject conducted CCFE and CCFE combined with VG in random order. The CVA was recorded using a digital camera and the ImageJ image analysis software. The EMG data of SCM and AS were measured by surface electromyography. A paired T-test was used to assess differences between the effects of the CCFE and VG combined with CCFE interventions in the same group. RESULTS: The CVA was significantly greater for CCFE combined with the VG than for CCFE alone (p<.05). The activity of the SCM and AS muscles was also significantly greater when the VG was combined with CCFE than during CCFE alone across all craniocervical flexion exercise phases (p<.05). CONCLUSION: Use of the VG technique combined with CCFE improved FHP in subjects with FHP compared to CCFE alone.

Purpose : The purpose of this study was to provide more effective interventions for elderly men with weak core muscles by measuring the thickness of the muscles according to the five core stabilization exercise and comparing the thickness differences in muscles in each posture. Methods : The study selected 29 elderly men aged 65 to 80 years old among outpatient patients at S Medical Center in B city, and measured the muscle thickness by exercise posture once. In order to find out the thickness of the external oblique (EO), internal oblique (IO), and transverse abdominis (TrA) muscles were measured by using rehabilitative ultrasound imaging (RUSI) in five exercise conditions. Results : A significant change in the thickness of the EO muscles in each group was measured by the method of motion, followed by the abdominal crunches (1.67±0.15), the lower body rotations (1.54±0.07). As a result of measuring the thickness of the IO muscles of each group according to the exercise method, the bridge group (1.14±0.22) was the highest, followed by the abdominal drawing group (1.05±0.03). As a result of measuring the thickness of the TrA muscles of each group according to the exercise method, the abdominal crunches (0.98±1.00) were the highest, and the bridge group (0.57±0.05) were higher in order of magnitude. Conclusion : Consequently, the five core stabilization exercises all affect changes in abdominal thickness and are expected to continue to require training studies on muscle posture.

Background: In patients with forward head posture (FHP), the head is positioned forward, causing increased tension in the muscles and structures of the head, neck, and shoulders. This can result in joint dysfunction that may lead to abnormal afferent information. The purpose of this study was to investigate the effect on foot pressure through the isometric hip abduction (IHA) bridge exercise using elastic bands in patients with FHP. Methods: Twenty patients with FHP were randomly assigned to a study group that applied joint mobilization, soft tissue mobilization, a deep neck flexor strengthening exercise, and the IHA bridge exercise using an elastic band. A control group was also constituted, and members were given joint mobilization, soft tissue mobilization therapies, and the deep neck flexor strengthening exercise. Ten patients were assigned to each group. The static foot pressure and dynamic foot pressure of each patient were measured before and after the intervention, and the interventions for each group were applied twice a week for 4 weeks. Results: Both the study group and the control group showed significant differences in static and dynamic foot pressure before and after the interventions (p<.05). There were no significant differences in foot pressure between the study and control groups. Conclusion: : The results of this study revealed that there were no significant differences between the group doing the IHA bridge exercise using the elastic band and the control group. However, the intervention methods applied to both the groups were effective in improving the body center control of FHP patients.

Purpose : The aim of study was to determine the effect of lower trapezius muscle strengthening exercises on the height of rounded shoulder posture and muscle activity in patients with rounded shoulder posture. Methods : Thirty-one subjects with rounded shoulders were selected and assigned, with the use of a random number table, to an experimental group (EG, n=16) that received resistance exercises of the trapezius (lower) muscles or a control group (CG, n=15) that received isometric exercises of the lower trapezius muscles. In the EG, with the subject in a prone position, both arms were abducted at the angles suggested for each posture (145 °, 45 ° abduction), with the hands holding dumbbells to assume a functional posture. The CG performed only isometric exercises without dumbbells in the same conditions. At the start signal, with the thumb raised, the arm was raised to the level of the ear. Both groups were assessed by the height of the rounded shoulder posture (RSP) and muscle activity (EMG). The intervention was performed three times a week. Results : The RSP significantly decreased during the intervention period in both the EG and CG (p<.05), and a significant difference was determined between the RSP of the two groups (p<.05). In the EG, the EMG significantly increased during the intervention period (p<.05), but the CG did not show any significant increase (p>.05). The final EMG was significantly higher in the EG than in the CG (p<.05). Conclusion : Both the EG and CG showed positive improvement in rounded shoulder posture during the intervention period. In particular, lower trapezius resistance exercise appears to reduce shoulder height and positively affects the activity of muscles around the shoulder.
