Background Abdominal muscles are important for stabilizing the trunk and reducing stress on the lumbar spine. In patients with neck pain, the cervical deep stabilizing muscles are weak and the cervical superficial muscles, such as the sternocleidomastoid (SCM), are dominantly activated. Craniocervical flexion (CCF) activates the deep cervical stabilizing muscles and reduces overactivation of the SCM. Objectives The purpose of this study was to investigate the effect of CCF on the activity of the abdominal muscles and cervical muscles during pilates hundred exercise in 12 healthy people. Methods Before the intervention, measure the maximal voluntary isometric contraction (MVIC) of the right SCM and rectus abdominis (RA) muscles. The muscle activity of the SCM and RA is measured when performing the Hundred with and without CCF in random order. Results There were statistically significant differences in SCM and RA activity during hundred according to two different neck positions. When performing the hundred with CCF, the activity of the SCM muscle significantly decreased and the activity of the RA muscle significantly increased compared to the hundred without CCF. Conclusions When instructing the pilates hundred, performing it together with CCF will be a way to activate the deep stabilizing muscles of the neck and effectively strengthen the abdominal muscles.

Background : In recent studies on back pain control, various exercises for strengthening the gluteus maximus have been suggested, however most of them imply load bearing exercise or giving resistance. Small knee bending is a movement evaluation that is frequently used in clinical practice and provides basic data for therapeutic intervention. It is also introduced as a safe way to exercise without applying a large load. Objectives : This study was conducted to investigate how the hip squeeze exercise using a tension sensor affects the muscle activity of the hip joint extension muscle during small knee bending. Methods : In this study, 30 subjects without back pain conducted to two conditions, with and without real-time visual biofeedback for small knee flexion. The hip squeeze force was measured using a tension sensor, and this was confirmed by real-time visual biofeedback. The muscle activities of hip extensors acting on the extension of the hip joint were measured by superficial EMG. To compare the difference in muscle activity under the two conditions, it was analyzed using a paired t-test. Results : As a result, the hip extensor muscle (gluteus maximus, both erector spinae) activity (maximum voluntary isometric contraction, %MVIC) significantly increased (p < 0.05) when real-time visual biofeedback using a tension sensor was applied compared to when it was not applied. Conclusions : Our study confirms that even a low-intensity exercise, such as a small knee flexion, can increase selective muscle activity if appropriate visual biofeedback is applied. In addition, the proposed hip squeezing method using a tension sensor induces selective muscle activity in a low-intensity exercise, which renders this method appropriate for subjects who do not exercise with great force, such as the elderly or women.

Background: The maximum voluntary contractile strength (MVCS) and sustained time at 50% submaximal voluntary contractile strength (SMVCS) using a pressure biofeedback unit have been used to measure the muscle strength and endurance of deep neck flexor muscles. However, to date, there has been no test-retest reliability study for this measurement method. Objectives: The purpose of this study was to measure the test-retest reliability of muscle strength and endurance of deep neck flexor using a pressure biofeedback unit, with and without visual feedback. Methods: Thirty healthy subjects were recruited for this study. Muscle strength and endurance of deep neck flexor were measured by pressure biofeedback unit and stopwatch. Intra-rater reliability of the deep neck flexor strength and endurance was analyzed using intraclass correlation coefficients (ICC 3, 1). Furthermore, the paired t-test was used to compare the sustained time of SMVCS of deep neck flexor between with and without visual feedback. Results: For MVCS, the value of ICC with (ICC: 0.965) and without visual feedback (ICC: 0.892) were both excellent. For the sustained time of SMVCS, the value of ICC with visual feedback were excellent (ICC: 0.910) while without visual feedback was fair to good (ICC: 0.654). Additionally, the sustained time of SMVCS of deep neck flexor was significantly greater with visual feedback than without visual feedback (p < 0.05). Conclusions: The measurement of strength and endurance using a pressure biofeedback unit with visual feedback can be recommended for reliable measurement of deep neck flexor muscle. Furthermore, the pressure biofeedback unit with visual feedback may be an effective method to increase the endurance of deep neck flexor muscles.

Purpose : The purpose of this study was to investigate the effect of Dang Dang integrated corrective therapy including myofascial release, chuna therapy, and exercise therapy on height, muscle mass, body fat, and body water in patients with body imbalance. The secondary aim was to investigate whether the percent of change in height, muscle mass, body fat, and body water varied by age group. Methods : In total, 279 patients with body imbalance between the ages of 10 and 79 were recruited at hospitals. All participants had Dang Dang integrated corrective therapy including myofascial release, chuna therapy, and exercise therapy. The patients’ height, muscle mass, body fat, and body water were measured before and after Dang Dang integrated corrective therapy using InBody. Results : The height, muscle mass, and body water significantly increased after Dang Dang integrated corrective therapy in all age groups except for the 70∼79 age group and body fat significantly decreased (p < .05). The age group comparison of the percent change in height, muscle mass, and body water showed significant differences (p < .05). In the post hoc test, the percent change of height in the 10∼19 age group was significantly greater than in the other age groups except for the 70∼79 age group. The percent change of muscle mass and body water in the 10∼19 age group was significantly greater than in the 30∼39 age group. Conclusion : These findings suggest that applying Dang Dang integrated corrective therapy to patients with body imbalance, excluding patients aged 70∼79, may be a useful method to increase height, muscle mass, and body water and decrease body fat through spinal and joint realignment. The best results were observed in teenagers.

Background : Posture imbalance is related to the loss of height and can frequently be managed by myofascial release (MFR), Chuna therapy, and exercise. Postural changes are not only affected by spinal flexibility, muscle activity, and passive tissue, but also exist gender differences. However, no research has investigated gender differences in height growth in patients with body imbalance when applying myofascial release, Chuna therapy, and exercise. Objectives : This study was designed to investigate the effect of integrated correction program (myofascial release, Chuna therapy, and exercise) on height for patients with body imbalance and compared gender differences Methods : In total, 166 patients (67 men, 99 women) with body imbalance were recruited. All participants performed integrated correction program. The height was measured using an Inbody. Differences in outcomes between pre and post integrated correction program were analyzed using a paired t-test. Gender differences of integrated correction program were analyzed using an independent t-test. Results : After 12 weeks integrated correction program, height was significantly increased post than before intervention in both men and women (men: t = -7.351, p < 0.001; women: t = -13.760, p < 0.001). The percent change of height was significantly greater in women compared in men (t = -2.760, p = 0.006). Conclusions : The integrated correction program will be a useful method to increase height by correcting posture imbalance, especially for women.
