연구배경: 호흡곤란은 심폐질환 환자의 가장 흔한 증상이며 호흡 장애 결과로 인한 운동 능력저하는 일상 생활을 불가능하게 한다.(daily disability) 운동시 산소 소모량은 운동 능력 평가의 기능적 척도이며 심폐기능 정도를 반영하는 가장 좋은 지표로 얄려져왔다. 그러나 운동 부하 검사는 장비가 비싸고 복잡하며 증상이 심하거나 노령층의 환자에는 수행에 많은 제약점이 따른다. 반면 걷기검사는 일상 생할과 비슷한 운동량으로 실시하여 특별한 장비가 필요없고 재현성이 높은 좋은 방법으로 알려져 있다. 따라서 호흡 곤란을 호소하는 환자에서 걷기검사를 시행하여 동맥혈검사 및 폐기능 검사, Modified Borg Scale(MBS), 최대 산소 흡수율(maximal oxygen uptake; 이하 VO2max) 간의 상관 관계 및 6분과 12분 걷기검사간의 상관 관계를 알아보고자 본 연구를 시행하였다. 방법: 호흡곤란을 주소로 내원한 37 명의 환자를 대상으로 COPD, 심혈관질환, 기관지 천식, 운동시 호흡곤란을 호소하였으나 정상 소견을 보인 네 군으로 분류하여 각각의 환자에서 안정 상태에서 폐기능 검사와 동맥혈 가스 분석을 실시하였다. 안정 시 MBS를 이용하여 호흡곤란 지수를 기록하고, 걷기검사를 실시하였다. 증상 제한적 최대 운용 검사(Symptorn-limited maximal exercise)는 자전거 타기 검사로 시행하였다. 결과: (1) 전체 환자에서 VO2max 은 COPD 및 심혈 관질환에서 다른 두군에 비해 유의하게 낮았으며 (p<0.05), 걷기검사 역시 현저히 낮았다. (2) 전체 환자에서 12분 걷기 검사는 VO2max, PaCO2, FVC(% predicted), FEV 1 (% predicted)과 상관관계가 있었으며, COPD 환자군에서는 걷기검사와 VO2max간에만 상관 관계가 있었다. (3) COPD 환자군에서 VO2max와 FEV1, FVC간의 상관관계가 가장 컸고, VO2 max와 걷기검사간에 유의한 상관관계가 있었으나 걷기검사와 FEV1 FVC간에는 상관관계가 없었다. (4) 6분 걷기검사와 12분 걷기검사는 매우 유의한 상관관계가 있었다(r=0.92, p<0.01). 결론: 걷기검사는 심폐기능을 반영하는 운동능력 평가의 간단한 방법으로 VO2max의 간접적인 지표로 유용하였으나 최대 운동 능력과는 다른 개념인 'daily disability'를 평가할 수 있는 방법이다. 또한 6분 걷기검사는 12분 걷기검사보다 환자의 부담은 줄이면서 심폐질환자의 폐기능 및 운동 기능 평가에 비슷한 결과를 보였다.

PURPOSE: The purpose of this study was to determine if an exercise program with vertical vibration can improve balance, walking speed, muscle strength and falls efficacy in the healthy elderly. METHODS: A total of 28 elderly were randomly divided into two groups: vertical vibration exercise group (exercise with vertical vibration) (N = 14) and control group (exercise without vibration) (N = 14). The exercise program, comprising calf raise, deep-squat, semi-squat, front lunge, and leg abduction was conducted with or without vibration, respectively. Subjects in each group participated in the 30 minutes training program, 2 times per week for 6 weeks. In both groups, the balance evaluation system (BT4) was used to evaluate standing balance, and walking speed was measured using the 10MWT. The manual muscle test system was applied to evaluate the knee extensor and ankle planter flexor muscle strength of the subjects, whereas the Korean falls efficacy scale (K-FES) evaluated the falls efficacy. RESULTS: After intervention, the vertical vibration group showed significantly higher changes compared to the control group, in the parameters of standing balance (P < .05), 10MWT (P < .05), left knee extensor (P < .05), right knee extensor (P < .01), both ankle plantar flexors (P < .05), and K-FES (P < .05). CONCLUSION: The exercise program with vertical vibration has the potential to improve balance, walking speed, muscle power and falls efficacy in the elderly.

Purpose : The purpose of this study was to investigate the effect of backward walking exercise on changes in the cervical angle and gait parameters in subjects with moderate forward head posture. Methods : Four subjects were selected for this study. In particular, subjects with an average of 43 subjects with moderate craniovertebral angles were selected as the criteria for subject selection. The exercise program consisted of a 5 minutes warm-up exercise, 20 minutes main exercise, and 5 minutes cool-down exercise. In the main exercise, the treadmill speed was 2.5 km/h for men, 2.0 km/h for women in the first week, from the 2nd week to the 4th week, it was increased by 0.5 km/h every week. Results : Craniovertebral angle increased by 2.06±2.46 ° before and after the backward walking exercise, and craniorotational angle decreased by -1.69±3.33 ° before and after exercise. As for the gait parameters, in the amount of change before and after the backward walking exercise, the left foot pressure was 4.58±5.70 % from front to back and the right foot pressure was 5.08±3.06 % from front to back. The left step length and right step length showed a change of -.33±4.43 cm and -2.08±7.26 cm, respectively. stride length showed a change of -2.59±11.18 cm. The left and right stance phase showed a change of -1.02±2.03 % and -1.23±1.54 %, respectively. The left and right swing phase showed changes of 1.02±2.03 % and 1.22±1.53 %, respectively. The left and right step times were -.01±.06 sec and -.02±.12 sec, respectively. The stride time showed a change of -.03±.18 sec. Conclusion : Changes in cervical angle and gait parameters were confirmed by performing backward walking exercise for subjects with moderate forward head posture for 4 weeks. Therefore, additional research should be conducted based on this case study.

Purpose : The purpose of this study is to investigate the effect of strengthening program for improving the muscle strength and body function in rehabilitation of patients with stroke Methods : We found the 15 precedent studies at online portal site of "Korea education and Research information service" and found 5 precedent studies at "Pubmed". We analyzed and describe the total 19 studies involving national and international research. Results : The strengthening exercise was adapted to lower extremities and trunk muscle of participants and the isokinetic (concentric and eccentric) exercise was most of exercise type and then manual isometric exercise, functional activities, progressive task oriented resistance exercise, PNF pattern exercise was following. The studies reported that the strengthening program increased target muscle strength and improved balance capacity and walking function for the participants positively. Conclusion : Conclusionally the several strengthening program can be the intervention to increase the muscle strength without increasing spasticity for patients with stroke. We think that the strengthening of lower extremities an improve balance capacity and walking ability and it can use the intervention to change the quality of life in patients with stroke. More than 3weeks strength program might be effectiveness, in case of acute patients with stroke, the improving of muscle strength is available but need to study for improving balance and walking capacity more in the future.

Purpose: The current study seeks to examine the effect of coordinative pattern exercises of the upper and lower extremities using harnesses and walking rails on the walking and balance abilities of chronic stroke patients, and to develop effective programs and training methods to improve the functions of such patients. Methods: Subjects included 16 patients with hemiplegia caused by stroke. The subjects were randomly divided into an experimental group (n=8), on which coordinative pattern exercises of the upper and lower extremities were conducted, and a comparison group (n=8) that received typical exercise therapy. The experimental group underwent 30 minutes of typical exercise therapy and 30 minutes of coordinative pattern exercises of the upper and lower extremities, while the comparison group underwent typical exercise therapy for 30 minutes twice a day, five days per week for a six-week period. To evaluate walking ability, 10-m walking tests (10MWT) and 6-m walking tests (6MWT) were conducted. To assess balance ability, timed up and go tests (TUG) were performed. Results: After the intervention, significant (p<0.05) differences were seen in the 10MWT, 6MWT, and TUG in both the experimental and comparison groups. As for the 10MWT, the experimental group showed more significant improvement than the comparison group (p<0.05). In terms of the 6MWT, no significant differences were found between the groups, while the experimental group showed more significant differences than the comparison group in the TUG (p<0.05). Conclusion: The results from the current research indicate that training programs that apply coordinative pattern exercises of the upper and lower extremities with harnesses are extremely effective for improving the walking and balance abilities of chronic stroke patients.
