Background: This study aimed to investigate the effect of hold-relax and antagonist contraction (HR-AC) technique and Kinesio taping on pain changes in delayed-onset muscle soreness (DOMS) of 20's adults. Methods: Based on voluntary participation, 14 participants with induced-DOMS were randomly divided into control (non-treatment, n=7) and experiment group (HR-AC technique and kinesio taping, n=7). Measurement were used visual analogue scale (VAS), heart rate variability (HRV), and brain wave (alpha). There were 5 sets of the HR-AC technique application on the 5th day from the day of DOMS induction (rest for 30s between sets). Kinesio taping was applied to the same area after HR-AC. Results: The VAS showed significant changes according to the period and in the interaction between the period and the group (p<.01). HRV and alpha wave (Fp1) showed significant changes according to the period (p<.001). The analgesic effect was more rapid and continuous in the experimental group than in the control group. Conclusion: This study showed that the HR-AC technique and Kinesio taping are effective interventions for the management of pain and stress caused by DOMS.

본 연구는 뇌병변으로 상지경직이 관찰되는 환자를 대상으로 자극방식에 따른 진동자극이 경직에 미치는 영 향에 대하여 알아보고자 하였다. 뇌병변으로 인해 상지경직이 있는 21명의 환자가 연구에 참여하였고, 실험군Ⅰ: 길항 근(상완삼두근)자극, 실험군Ⅱ: 주동근(상완이두근)자극, 실험군Ⅲ: 동시(상완삼두근 및 상완이두근)자극에 각 7명씩을 배정하여 진동자극을 실시하였다. 척수운동신경원 흥분성을 알아보기 위해 Neuro-EMG_Micro를 이용한 F파를 자극 전, 자극 직후, 자극 10분 후, 자극 20분 후에 측정하였고, 임상적 평가로는 MAS(Modified Ashworth Scale)와 MFT(Manual Function Test)를 자극 전, 자극 20분 후에 평가하였다. 본 연구의 결과, MAS는 세군 모두 유의한 감소 를 나타냈고, F파 진폭 및 F/M비에서는 세군 모두에서 자극 직후에서부터 유의한 감소를 나타냈으며, 실험군Ⅲ에서 시간 경과상 변화량이 가장 크게 나타났다. MFT에서는 실험군Ⅱ와 Ⅲ에서 유의한 증가를 나타냈으며 특히, 실험군Ⅲ 에서 기능적 변화량이 가장 크게 나타났다. 이러한 결과는 경직근에 대한 진동자극시 경직 주동근이나 길항근에 대한 단일 자극 방식보다는 동시자극 방식이 척수운동신경원의 흥분성 감소 및 상지 운동 기능 향상에 더 효과적임을 확 인할 수 있었다. We studied the effects of vibration stimulation method on upper limbs spasticity in patients with brain lesion. 21 patients with spasticity of the upper limbs selected and divided randomly 3 groups. And then vibratory stimulation was applied to the triceps brachii muscle in group Ⅰ(n=7), to biceps brachii muscle in group Ⅱ (n=7), and to both muscles in group Ⅲ (n=7). Using Neuro-EMG_Micro to investigate the changes in spinal neuronal excitability, F-waves were measured at before and directly after stimulation, and 10 minutes later and 20 minutes later after stimulation especially. MAS(Modified Ashworth Scale) test for muscle tone and MFT(Manual Function Test) for the upper extremity motor function were performed before stimulation and 20 minutes later after stimulation for the purpose of clinical evaluation. In our study, MAS was significant decreased in all groups, F wave and F/M ratio parameters were decreased in all groups and more decreased specially in group Ⅲ. MFT was increased in group Ⅱ and Ⅲ, and more increased specially in group Ⅲ. Vibration stimulation reduced the neuronal excitability of spinal cord and also muscle tone, and improved the motor function of the upper extremity. These results suggested that vibration stimulation giving to both muscles(triceps and biceps brachii muscle) at the same time was more efficiency in reducing the neuronal excitability of spinal cord and improving the motor function of the upper limbs.

본 연구의 목적은 뇌졸중 환자에서 주관절 각도 변화에 따른 상완이두근(biceps brachii)의 근구조 및 탄성 변화에 관하여 알아보고자 하였다. 연구대상은 주관절 수동 ROM범위가 10°∼90°가능하며 MAS(modified Ashworth scale) 1∼3등급인 뇌 졸중 환자 12명을 대상으로 하였다. 이완(resting) 상태의 건측과 환측 상완이두근의 우모각, 근섬유속길이, 근탄성의 측정 은 초음파 영상 촬영장치와 근긴장도 측정기(myotonometer)를 이용하여 주관절을 10°∼90°로 변화시키면서 측정하였다. 본 연구 결과, 환측 상완이두근을 건측과 비교 시 우모각은 신전위치(<40°)에서 큰 값을 나타냈으며(p<.05), 근섬유속길이 는 굴곡위치(>20°)에서 짧은 길이를 나타냈으며(p<.05), 근긴장은 신전위치(<50°)에서 전위 값이 낮게 나타나 근긴장이 높 아짐을 나타냈다(p<.05). 이렇듯 이완 시 상완이두근의 근구조 및 탄성은 주관절 각도에 의해 영향을 받는다는 것을 알 수 있었다. 본 결과를 뇌졸중 환자의 근구조 변화 및 임상치료의 연구 자료로 사용할 수 있을 것으로 생각된다. The aim of this study was to find on muscle architectural and tissue compliance of biceps brachii in stroke patient based on elbow joint angle. The subjects of this study were twelve hemiplegic adults after stroke with passive range of motion in the elbow from 10° to 90° and Modified Ashworth Scale score 1 to 3 were recruited. Ultrasonography and Myotonometer was used to measure biceps brachii muscle pennation angle, fascicle length, and tissue compliance at the rest condition and pennation angle, fascicle length, and tissue compliance of the biceps brachii muscle were measured in the affected and unaffected sides of people after stroke at 9 different elbow angles ranging from 10° to 90° at the rest condition. The results of this study, comparisons found that the pennation angles of the affected biceps brachii muscle were significantly larger(p<.05) than the unaffected muscle in the most extended positions(<40°), whereas the affected fascicle lengths were significantly shorter(p<.05) than the unaffected muscle in most flexed positions(>20°), and the affected tissue compliance were significantly lower(p<.05) than the unaffected muscle in most extended positions(<50°) Therefore, pennation angles, fascicle lengths, and tissue compliance were found to be joint-angle-dependent in both the affected and unaffected sides at the rest condition. Suggest that, the results data can be used as a muscle architectural changes and clinical treatment research in stroke patients.

배세현(Bae, Sea-Hyun),이정인(Lee, Jeong-In),김경윤(Kim, Kyung-Yoon) 한국산학기술학회 2012 한국산학기술학회논문지 Vol.13 No.3

본 연구의 목적은 뇌졸중 환자의 족관절 저측굴근 경직에 대하여 Myotonometer와 surface Electromyography (sEMG)를 이용하여 경직의 정량적 평가에 유용한 지표를 알아보고, 이 지표들과 임상적으로 평가되는 modified Ashworth scale(MAS)과의 관계를 알아보고자 하였다. 족관절 저측굴근의 경직평가는 물리치료사 5명(임상경력 5년이 상)이 MAS를 이용하여 MAS 2, 3, 4 해당 군에 각 5명씩을 무작위로 15명씩 배정하였다. 각 군의 조직탄성과 근활 성 측정은 Myotonometer와 sEMG로 이완(relaxed)상태와 최대 수의적 수축(contracted)상태에서 측정하였다. 연구 결과, MAS 등급이 높아짐에 따라 이완과 수축상태 간의 조직저항도 전위차와 근활성도의 차이는 작아졌고, 상관관계 분석 에서도 MAS 등급이 높아질수록 이완 시보다 수의적 수축 시 실린더가 받는 낮은 강도에서의 상관성이 더 높아짐을 확인할 수 있었다. 따라서 Myotonometer는 경직을 평가하는 방법으로 다양한 인체의 관절에 비교적 쉽게 적용할 수 있으며 경직의 변화를 민감하게 반영할 수 있어 보다 객관적이고 정량적인 경직의 평가 도구로 사용될 수 있을 것이다. The aim of this study was to find useful parameters of the between myotonometer and surface electromyography(sEMG) on the medialis gastrocnemius of stroke patients and investigate between these parameters and modified Ashworth scale(MAS) relationship. 5 years clinical experience physical therapist using the Modified Ashworth Scale(MAS) was selected 15 patients with ankle spasticity and divided randomly MAS2, MAS3, MAS4 groups. Myotonometer and sEMG was measured during relaxed and maximum voluntary contractions of the gastrocnemius muscle. The results of this study, the higher MAS score was the lowered the relaxation and contraction state tissue compliance and muscle activity and in the correlation analysis the higher MAS score during voluntary contraction in the cylinder receiving low-intensity correlation could see that increased than relaxation. Therefore, the myotonometer is a useful clinical and research tool with spasticity muscle and can provide objective quantitative data about the efficacy of physical therapy interventions.

PURPOSE: The purpose of this study was investigate the changes of gastrocnemius (GCM) muscle activity by applying different hot and cold therapeutic modalities. METHODS: A total of 20 healthy subjects were enrolled into the study. We selected transfer modalities that are frequently used in clinical settings: conduction, radiation, and convection. We performed hot pack, ice pack, and infrared therapy for 10, 20, and 30 minutes. After each application, a break was taken between each day. In addition, we performed cryotherapy for 3 min (airflow rate = -6~-20℃). We measured muscle activity changes in the GCM muscle. RESULTS: For the conduction method, muscle activity significantly increased after ice pack therapy for 10 min and 20 min but decreased after hot pack therapy for 10 min and 20 min. For the radiation method, muscle activity significantly decreased after infrared therapy for 10 min and 20 min. For the convection method, muscle activity significantly increased after cryotherapy for 3 min and 10 min. There were no differences in the change of muscle activity in the conduction and radiation transfer method using heat. However, there were differences in the change of muscle activity in the conduction and convection transfer method with cold application. CONCLUSION: For a reduction in muscle activity, regardless of the transfer type, thermal application for 20 min would be effective. For an increase in muscle activity, cold pack application or cryotherapy for 20 min would be effective. This study could contribute toward therapeutic modality application in changing muscle activity.
