This study examined the effects of a physical therapy program on quality of life (QOL), and neck and shoulder disability in head and neck cancer patients. The program included neck and shoulder range of motion (ROM) exercises, massage, progressive strengthening exercises, and stretching exercises. Sixteen patients who were assigned to an experimental group performed physical therapy for 40 minutes three times a week for eight weeks. Fifteen other patients were assigned to a control group who did not performed the physical therapy program. The European organization for research and treatment of cancer (EORTC QLQ-C30) and head and neck (EORTC QLQ-H&N) instruments, and the Neck Disability Index (NDI) were assessed before and after the rehabilitation program. The 40-minute program consisted of a 10-minute ROM exercise for the neck and shoulder, a 10-minute massage and 15-minute of progressive resistance exercises, followed by a five-minute stretching exercises. Statistically significant differences were noted for changes in global health, physical function in the EORTC QLQ-C30 and cancer related symptoms in the EORTC QLQ-H&N35 (p<.05). The NDI also showed significant differences (p<.05). Physical therapy may therefore benefit the physical aspects and QOL and improve neck and shoulder disability in patients with head and neck cancer.

This study examines the effects of a rehabilitation program on quality of life (QOL), cardiopulmonary function and fatigue during radiotherapy for breast cancer patients. The program includes aerobic exercise, stretching and strengthening exercises. Sixty-five women participated in this study and they were asked to perform supervised exercises that last for 60 minutes five times a week for six weeks. The European organization for research and treatment of cancer-cancer (EORTC QLQ-C30) and the breast (EORTC QLQ-BR23), predicted maximal volume of oxygen consumption () and fatigue severity scale (FSS) were assessed before and after the rehabilitation program. The 60-minute program consisted of a 10-minute warm-up, 30-minute of aerobic exercises, and 15-minute of strengthening exercises, followed by a five-minute cool-down. Heart rates were monitored throughout the exercise class to ensure that patients were exercising at the target heart rate of 40~75% of the age-adjusted heart rate maximum. There were statistically significant differences in the changes of physical function and cancer related symptoms in the EORTC QLQ-C30 and EORTC QLQ-BR23 (p<.05). There was a statistically significant improvement in the predicted (p<.05), although there were no significant differences in the FSS (p>.05). The results of our study suggest that a supervised rehabilitation program may benefit the physical aspects and QOL of patients receiving radiotherapy for breast cancer.

The purpose of this study was to compare the anaerobic threshold (AT) between subjects with and without non-specific chronic low back pain (NCLBP). The patient group included 15 women with NCLBP. The normal group included 15 women without NCLBP who were age-, height-, weight-, and activity level-matched. The subjects performed a Balke treadmill protocol which was symptom-limited progressive loading test. Their heart rate (HR), ventilatory gas and metabolic equivalents (METs) were measured using the automatic breath gas analyzing system. After the test, each subjects' ratings of perceived exertion (RPE) were evaluated. The visual analog scale (VAS) was assessed pre- and post-test. The independent t-test and Wilcoxon's signed-rank test were used for analysis of the data. Time, HR, the volume of oxygen consumption (), relative , and METs at the AT level of the patient group were significantly lower than those of the healthy group (p<.05). However, there were no significant differences in RPE, VAS, and breathing frequency at the AT level (p>.05). The findings of this study indicate that patients with NCLBP had a lower aerobic fitness than healthy subjects. Thus, implementation of rehabilitation program to increase aerobic fitness may be considered in patietns with NCLBP, and further studies are required to determine the etiological factors of decreased aerobic fitness.

본 연구는 산의 남쪽 면에 동서 방향으로 길게 건축한 두 동의 개방돈사 간의 이격거리와 높이차가 환기에 어떤 영향을 미치는지를 시뮬레이션 기법을 이용하여 비교분석하고자 수행되었다. 개방돈사 간의 이격거리는 6과 12 m로, 개방돈사 간의 높이차는 0과 2 m로, 그리고 평균풍속은 여름 1.3과 겨울 1.1 m/s로 각각 설정하였다. 여름철 조건 하에서, 남쪽에 있는 첫 번째 개방돈사 내부의 풍속은 이격거리 및 높이차와는 상관없이 0.75 m/s로 각각 나타났으나 북쪽에 있는 두 번째 개방돈사의 풍속은 높이차가 없을 때 첫 번째 개방돈사의 풍속과 같은 0.75 m/s였고 높이차가 2 m일 때 0.0 m/s에 매우 가깝게 나타났다. 겨울철 조건 하에서, 남쪽에 있는 첫 번째 개방돈사 내부의 풍속은 높이차와는 상관없이 0.15 m/s로 각각 나타났으나 북쪽에 있는 두 번째 개방돈사의 풍속은 이격거리가 12 m일 때 첫 번째 개방돈사의 풍속과 같은 0.15 m/s였고 이격거리가 6 m일 때 0.0 m/s에 매우 가깝게 나타났다. 따라서 개방돈사 간의 이격거리를 12 m 정도로 하고 계단형태보다는 평지형태로 정지작업을 하여 개방돈사를 건축하는 것이 바람직한 것으로 판단되었다.
