Objective: This study aimed to assess the impact of using the LED light electromyographyfeedback system (EMG-light) during Pilates exercises in women to maintain consistent muscle contraction in the abdominal external oblique muscles and reduce muscle contraction in the upper trapezius muscles. This study compared Pilates training using the EMG-light with Pilates training only in healthy women for 4 weeks. Design: This study was conducted as a cross-sectional study. Methods: A total of 17 healthy women were divided into an experimental group (n=9) and a control group (n=8). Both groups performed Pilates exercises as assigned, twice per week for four weeks, with each session lasting fifty minutes. The experimental group were used the EMG-light feedback system during pilates exercise while the control group did not use EMG-light. We used cervical vertebral angle (CVA), shoulder tilt angle to evaluate neck posture and standing balance with closed eye for 30s before and after exercise. Results: The control group exhibited a significant change in CVA (p<0.05). Both groups showed significant changes in shoulder tilt, center of pressure (COP) path-length, and COP velocity during eyes-closed conditions (p<0.05). However, there were significant differences between the experimental and control groups in terms of CVA, shoulder tilt, COP path-length, and COP velocity. Conclusions: This study demonstrated that Pilates exercises had positive effects on shoulder posture and balance. The use of EMG-light provided real-time visual feedback on muscle contraction during Pilates exercise. However, the experimental group did not show significant improvements compared to the control group, which performed Pilates exercises without feedback.

본 논문에서는 키넥트 센서를 기반으로 한 휘트니스(Fitness) 동작의 정확성을 피드백 하는 윈도우 애플리케이션 KITNESS를 설계하고 구현한다. 이 애플리케이션의 특징은 키넥트의 카메라와 관절 인식 센서를 활용하여 사용자가 정확한 휘트니스 자세로 운동할 수 있도록 피드백을 주는 것이다. 이때 키넥트의 IR Emitter와 IR Depth Sensor를 이용하여 사용자와 키넥트 간의 거리를 측정하고, 사용자의 관절 위치인 조인트(Joint)와 각 관절의 스켈레톤(Skeleton) 데이터를 측정한다. 이러한 데이터를 이용하여 사용자의 관절 위치와 자세마다 일정 거리를 계산하고 자세의 정확도를 판단한다. 그리고 키넥트의 RGB 카메라를 통해 사용자가 본인의 자세를 확인할 수 있도록 구현한다. 즉, 사용자의 자세가 정확하면 스켈레톤 정보를 초록색 선으로 표시하고, 정확하지 않으면 정확하지 않은 부분을 빨간색 선으로 표시하여 직관적으로 알려준다. 사용자는 이 애플리케이션을 통하여 운동하는 자세의 정확도를 피드백 받기 때문에 혼자서도 정확한 자세로 운동할 수 있다. 이 애플리케이션은 운동 부위를 목, 허리, 다리 세 가지 영역으로 분류하고, 각 운동 부위의 자세에서 관절이 겹쳐서 키넥트가 인식하지 못하는 자세를 제외함으로써 키넥트의 인식률을 높인다. 그리고 애플리케이션 종료 시에는 마지막 운동 모습을 이미지로 5초간 보여줌으로써 성취감을 고취시키고 지속적으로 운동할 수 있도록 구현한다.

PURPOSE: This study examined the effects of the craniovertebral angle, proprioception (joint error test), and the upper trapezius on the muscle tone when comparing cervical stabilization and scapula stabilization exercises and when two exercises were performed together. METHODS: The participants in this study agreed in advance, and this study was carried out by recruiting 27 university students in their twenties with mild frontal posture. The subjects were assigned randomly to three groups that performed cervical stabilization exercises, scapular stabilization exercises, and both cervical and scapular stabilization exercises. One-way repeated ANOVA was used to analyze the evaluation values of the 1^st, 3^rd, and 6^th weeks of exercise intervention within the group, and one-way ANOVA was used to compare the difference in the effects of exercise intervention among the three groups. RESULTS: Proprioception was significantly different in the cervical stabilization exercises (CSE) group and the cervical stabilization exercises + Scapular stabilization exercises (CSE+SSE) groups at three weeks, and there was a significant difference between the scapular stabilization exercises (SSE) group and the CSE+SSE group (p < .05). At six weeks, there was a significant difference between the CSE group and the CSE+SSE group, and there was a significant difference between the SSE group and the CSE+SSE group (p < .05). There was a significant difference between three and six weeks in the CSE group (p < .05). In the SSE group, there was a significant difference between pre and six weeks, and between three and six weeks (p < .05). In the CSE+SSE group, there was a significant difference between pre and three weeks, and between pre and six weeks (p < .05). On the other hand, there were no significant differences between CVA and muscular tone in all three groups (P > .05). CONCLUSION: In all groups, the proprioception (joint error test) showed significant improvement, and the CSE+SSE group showed greater improvement than the other groups. As a result, the appropriate combination of neck stabilization exercise and scapular stabilization exercise effectively improved proprioception in the presence of forward head posture (FHP).

The aim of this study was to compare the electromyographic (EMG) activity levels of the scapular upward rotators [upper trapezius (UT), lower trapezius (LT), and serratus anterior (SA)] and other scapular muscles [posterior deltoid (PD), levator scapulae (LS), and infraspinatus (IS)] during isometric lower trapezius exercises. Twenty males with no medical history of shoulder pain or upper extremity disorders were recruited for this study. EMG activity was recorded from the UT, LT, SA, PD, LS, and IS while subjects performed three different exercises: Prone arm lift (PAL), Backward rocking diagonal arm lift (BRDAL), Modified Prone Cobra (MPC). One-way analysis of variance (ANOVA) was used to determine any significant differences among the three exercises. A lower relative activation of UT, LT, and SA was seen with the MPC than with the other exercises (p<.05). The relatively lower activation of the UT identified, the MPC exercise as the preferred choice for preferential strengthening the LT (p<.05). However, a higher activation in the PD, LS, and IS occurred with the MPC than with the other exercises (p>.05). The recruitment pattern of synergist varied depending on the exercise posture. These findings suggest that exercise posture is an important factor in the selection of strengthening exercise for weak muscle.

Objective: The purpose of this study was to investigate the effect of treadmill exercise on the posture and walking speed of chronic stroke survivors with an ankle-foot orthosis. Design: Randomized controlled trial. Methods: Twenty-four chronic persons with chronic stroke admitted to Bobath Memorial Hospital in Seongnam city were divided into two groups by random blind method. Treadmill exercise with an elastic ankle-foot orthosis was performed in the experimental group and treadmill exercise was performed in the control group. The experiment was carried out for 6 weeks, and the experiment was carried out three times a week for 20 minutes per session. To measure the effect, static balance was measured using the MTD system before and after training, and the Berg Balance Scale (BBS) was used to measure functional balance. Results: There was a statistically significant difference between the 2 groups in the BBS measurement results for confirming the functional balance (p<0.05). Also, there was a significant difference between the 2 groups in single limb support time, step time and step length (p<0.05). Conclusions: In this study, it was found that treadmill exercise with an elastic ankle-foot orthosis in persons with chronic stroke was effective in maintaining functional balance, walking ability, step length, and step time. Therefore, it is necessary to use a flexible ankle-foot orthosis with proper treadmill exercise as a method of improving balance and walking speed of chronic stroke survivors.

Purpose: The study aims to determine the effect of a breathing exercise on shoulder pain, range of motion (ROM), and forward head posture in patients with rotator cuff repair. Methods: In total, 25 patients with rotator cuff repair were included in this study. The experimental group (n = 13) underwent a breathing exercise, while the control group (n = 12) received traditional physical therapy. The visual analogue scales (VASs) for pain, flexion and abduction ROM, and the craniovertebral angle (CVA) of both groups were recorded at both pre- and post-intervention. Paired t-tests were used to determine significant changes in the post-intervention compared with the pre-intervention period, and independent t-tests were used to analyze differences in dependent variables between the two groups. Results: After the two-week intervention, the experimental group experienced a significantly decreased VAS (p < 0.05) and significantly increased ROM and CVA (p < 0.05), while the control group experienced a significantly decreased VAS (p < 0.05). Further, the experimental group that underwent the breathing exercise showed greater improvements in flexion and abduction ROM and in the CVA than the control group (p < 0.05). Conclusion: The results suggested that a breathing exercise can reduce shoulder pain and enhance ROM and posture in patients with rotator cuff repair.
