  • 본 연구에서는 Pneumatic air fitting system을 적용한 기립보조기 제품을 뇌병변 소아환자를 대상으로 기립보조기의 신체 고정용 폼패드(foam pad)와 에어패드(air pad) 사용 시, 뇌병변 장애아동들의 체간 및 하지근육의 수축 양상을 비교 분석하였다. 연구결과, 패드(foam pad vs. air pad) 유형에 따른 근육별 근력 활성도는 차이가 있었다. 이러한 차이는 큰 동작(식사동작)에서 크게 나타나고, 작은 동작(쓰기동작, 읽기동작)이 작게 나타났다. 이는 Pneumatic air fitting system을 적용한 기립보조기 제품 사용 시, 기존 폼패드에 비해 사용자에게 좀 더 편안함을 제공하는 것으로 나타났다.

  • 본 연구는 태권도 겨루기 경기에서 많이 사용되고 있는 받아차기 종류 중에서 반달차기 동작을 운동학적 변인과 근전도적 변인들에 대하여 카메라와 근전도 시스템 기법을 통해 분석하여 규명함으로써 태권도 겨루기 선수들과 지도자들에게 경기력 향상을 위하여 보다 효율적인 반달차기 수행능력을 제시함을 연구목적으로 하며 운동학적 및 근전도를 분석한 연구 결과는 다음과 같다. 태권도 겨루기 경기에서 반달차기는 발을 차는 다리의 슬관절 각 변위 변화가 상대를 임팩트 하는 순간 대단히 중요한 요인이 되며, 고관절 각변위는 발을 차는 다리와 상체 젖히기 각변위 변화는 매우 중요한 요인이다. 또한 근전도 변인들 중에서 반달차기 동작 수행 시에 차는 발의 반대쪽에 위치한 왼쪽부분의 척추기립근 근육들이 높은 근활동에 기여되고 있어 경기력 향상을 위한 효율적인 반달차기 수행능력을 위해서는 왼쪽부분에 위치한 척추기립근 근육들의 강화 훈련이 필요하다고 할 수 있으며, 체간운동에 따른 오른발반달차기 동작 시 오른쪽 부분에 위치한 복근이 높은 근활동에 기여함으로서 효과적인 반달차기 수행능력을 발휘 할 수 있을 것이다.

  • 본 연구의 목적은 무중력 운동기구를 활용한 하이플랭크 운동 동작 차이에 따른 상완, 체간 및 코어근육의 근활성도를 비교하는 것이었다. 본 연구의 대상자는 20대 남성 6명을 대상으로 진행하였고(연령, 23.00±0.73 세; 신장, 172.95±2.05 cm; 체중, 66.83±2.75 kg; 신체질량지수, 22.33±0.72 kg/m2), 4가지(HP, HPAW, HPSB 및 HPWT)의 하이플랭크 동작을 수행하였으며, 근활성도 분석을 위하여 구체적인 표면전극의 부착 부위는 신체 근육의 우측 삼각근, 상완삼두근, 광배근 및 외복사근으로 설정하였다. 본 실험 결과, 삼각근, 상완삼두근, 광배근 및 외복사근의 근활성도는 HPSB 동작 시 가장 높게 나타났다(p=.000). 따라서 본 연구의 결과는 추후 무중력 운동기구를 활용한 하이플랭크 동작 시 효과적인 운동 프로그램의 기초자료가 될 것으로 기대된다.

  • Purpose: This study examined the muscle activity of the trunk muscles during weight shifting exercises on a stable and unstable surface. Methods: Ten healthy young subjects (4 males, 6 females) with no medical history of lower-extremity or lumbar spine disease were enrolled in this study. The muscle activity was recorded using surface electromyography (EMG) electrodes from the both sides of the external obliques and erector spinae muscles. Results: The EMG activities of the both rectus abdominalis, both external obliques and erector spinae muscles were significantly higher when the weight shifting exercise was performed on a firm surface than when a balance pad with a balance ball was used. In weight shifting exercises, the EMG activity of the contralateral external obliques and erector spinae muscles was significantly higher than that of the ipsilateral external obliques and erector spinae muscles under all three support surface conditions. Conclusion: Performing weight shifting exercise using an unstable surface is a useful method for facilitating the trunk-muscle strength and trunk stability.

  • PURPOSE: The purpose of this study was to investigate the effect of distance between trunk and desk on forward head posture and muscle activity of neck and shoulder muscles during computer work. METHODS: Twenty subjects who have healthy conditions were asked to perform computer work in two conditions (distance between trunk and desk was 0 and 15 cm). Forward head angle was analyzed with a SIMI motion analysis system. Surface electromyography recorded the upper trapezius and splenius capitis muscles. The significance of differences in distance between trunk and desk (0cm and 15cm) was tested by paired t-test. The alpha level was set at .05. RESULTS: The results showed that the change of forward head angle was significantly higher during the computer work when the distance between trunk and desk was 15cm than 0cm. The muscle activity of upper trapezius and splenius capitis was also significantly higher during the computer work when the distance between trunk and desk was 15cm than 0cm. CONCLUSION: Our study suggest that the distance between trunk and desk was should minimized for prevention of forward head posture during computer work.

  • Purpose : The aim of this study is to compare the trunk muscle activities in trunk stabilization on the stable and unstable supporting surfaces using by sEMG. Methods : The subjects of this study include seventeen male. We measured sEMG activities of rectus abdominis and erector spine in subjects during trunk stabilization such as plank exercise, quadruped position, quadruped position with rising hand and foot on the stable and unstable surface. Results : sEMG activities in plank exercise was significantly higher in left rectus abdominis and left erector spine on unstable surface then stable surface (p<.05). sEMG activities of left rectus abdominis and left erector spine in quadruped position was significantly higher in unstable surface than stable surface (p<.05). In comparison with posture, Plank exercise showed a significant difference increase other postures (p<.05). Conclusion : sEMG activities of muscle in trunk stabilization was significantly higher in unstable surface than stable surface and plank exercise. So, we suggest that trunk stabilization on the unstable supporting surface and plank exercise were more effective method than stable surface to improve trunk muscles activities.

  • Purpose: The aim of this study was to examine the activation of the contralateral upper and lower extremities and trunk muscle during ipsilateral upper extremity diagonal isokinetic exercise. Methods: Twenty-one healthy male subjects with no history of shoulder injury undertook ipsilateral diagonal isokinetic exercise at 60, 120, and $180^{\circ}/sec$, utilizing a standard Biodex protocol. Muscle activation amplitudes were measured in the upper trapezius, pectoralis major, biceps brachii, rectus abdominis, external oblique, rectus femoris, adductor longus, and biceps femoris muscles using electromyography. A one-way analysis of variance and paired t-tests were conducted, and the data were analyzed using SPSS, version 21.0. Results: The results revealed no statistically significant interaction between motion and angular velocity and no statistically significant contralateral muscle activation according to angular velocity (p>0.05). However, they revealed statistically significant contralateral muscle activation according to motion (p<0.05). Conclusion: These results suggest that the movements involved in contralateral upper extremity diagonal isokinetic exercise can enhance muscle strength in patients affected by stroke, fracture, burns, or arthritis.

  • Purpose : Bridge exercise has been commonly used in clinical rehabilitation settings to improve trunk control, and hip adductor muscles were a related muscle that may affect trunk muscle activation. The aim of this study was to investigate whether the co-contraction of hip adductor muscles may affect trunk muscle activation during bridge exercises. Methods : Thirty-eight healthy young subjects (19 men and 19 women) performed bridge exercises (with and without hip adduction movement). Surface electromyography (EMG) data were collected from the dominant-side internal oblique (IO), rectus abdominis (RA), multifidus (MF) and erect spine (ES) during bridge exercises to compare trunk muscles activation patterns. Result : The EMG activities of IO and RA appeared to be significantly higher during bridge exercise with hip adductor co-contraction than during bridge exercise alone (p<.01), but there were no significant differences in those of MF and ES. Furthermore, there were significant differences in the IO:RA EMG ratio during bridge exercise with hip adductor co-contraction (p<.05). Conclusion : These findings suggest that integration of hip adduction during bridge exercise may be beneficial in increasing deep muscles' activity for trunk stabilization.

  • Purpose : The purpose of this study was to analyze the effect of PNF lower extremity flexion pattern on the eletromyographic (EMG) activity in rectus abdominis, internal oblique abdominal, external oblique abdominal, erector spinae. Methods : Twenty-six healthy adults volunteered to participate in this study. Subjects were required complete following two PNF lower extremity patterns; flexion-adduction-external rotation with knee flexion (D1) and flexion-abduction-internal rotation with knee flexion (D2). A paired t-test was used to determine the influence of the PNF two patterns on muscle activity for each muscle and descriptive statistics was used to determine local/global muscle ratio. Results : The D1 pattern was showed significant rectus abdominis (p<.05) and Median of internal oblique/rectus abdominis ratio was 2.23 and internal oblique/external oblique ratio was 1.53. The D2 pattern showed significant erector spinae (p<.05) and Median of internal oblique/rectus abdominis ratio was 3.06 and internal oblique/external oblique ratio was 1.72. Conclusion : The D1 pattern made rectus abdominis activation increase. The D2 pattern made erector spinae activation increase. As compared D1 and D2 pattern on trunk muscle activation, it's will be useful decision making for the trunk muscle strength and stabilization.
