Osteoporosis is characterized by low bone mass and the microarchitectural deterioration of bone tissue with a consequent increase in bone fragility and susceptibility to fracture. It has been suggested that speed of sound (SOS) and broadband ultrasound attenuation (BUA) of quantitative ultrasound sonography (QUS) may provide information about not only bone density but also the microarchitecture and elastic properties of bone. Physical inactivity reduced mechanical usage and it made process to the bone changes. This study aimed to association between the physical activity and the QUS parameters in 1305 (593 men, 712 women) aged 20 years over in a rural population. Two QUS parameters, BUA (p=.23) and SOS(p=.73) were measured at the right calcaneus of postmenopausal women, no significant associations were observed between sports index and SOS and BUA. These results suggest that work, non-sports leisure physical activity (p<.01) have a significant influence on QUS parameters in a rural population. Physical activity are meaningful predictor of QUS parameters of the calcaneus in a rural population.

본 연구는 스포츠 아우터웨어용 나일론 직물의 소리에 대한 주관적 감각과 이에 관련된 객관적 측정치를 규명하기 위하여, 서로 다른 8종의 나일론 직물의 소리의 스펙트럼 파형을 고찰하였으며, 소리 파라미터로 총음압(level pressure of total sound, LPT),세 가지 AR (autoregressive)계수, Zwicker의 심리음향학적 모델에 따른 크기(Z)와 날카로움(Z)를 계산하였고, Kawabata Evaluation System(KES)으로 직물의 물리적 성질을 측정하였다. 주관적 감각 평가를 위하여 피험자에게 녹음된 각 직물소리를 들려주어 7개 소리 감각 (부드러움, 시끄러움, 날카로움, 맑음, 거 침, 높음, 유쾌함)을 의미분별척도로 답하게 한 후, 단계적 선형 회귀식을 이용하여 직물 소리의 주관적 감각에 대한 예측 모델을 제시하였다. 울트라스웨이드를 제외한 태피터 나일론 직물들은 스펙트럼 파형 에서 다른 조성 섬유의 직물들보다 음압 값이 높고, 총음압이 60dB 안팎의 값을 보여, 착용자에게 불쾌감을 줄 것으로 예상되었으며, 주관적 감각 평가에서도 소리의 부드러움과 맑음, 유쾌함에서 음의 점수를, 시끄러움과 날카로움, 거침, 높음에서 양의 점수를 얻었다. 주관적 감각의 예측모델에서 총음압은 시끄러움과 거침에 정적 영향을, 유쾌함에 부적 영향을 미쳐서 나일론 직물 소리의 총음압이 50dB 이하일 때 주관적으로 유쾌하게 느껴지는 것으로 나타났다.

This study compared the effect of therapeutic exercise with conservative treatment in women with chronic neck pain. Subjects were allocated to control, neck isometric exercise, and cervical stabilization exercise groups consisting of 29, 32, and 31 patients, respectively. The conservative treatment for the control group consisted of hot packs, ultrasound, interferential current therapy, and intermittent cervical traction. The neck isometric exercise group performed a neck isometric exercise and the cervical stabilization exercise group performed a cervical stabilization exercise. To compare the three groups, the levels of perceived pain, neck disability, and psychological depression were assessed on admission, at discharge, and one month after discharge. On admission and at discharge, the pain and neck disability scores did not differ significantly among the groups. However, one month after discharge, both the neck isometric and cervical stabilization exercise groups had significantly improved perceived pain levels as compared to control (p<.05). The improvement in the degree of neck disability was most significant in the cervical stabilization exercise group (p<.05). On comparing the changes in the variables at the three assessments for each group, there was a significant difference between the control and cervical stabilization exercise groups (p<.05). The findings indicate that therapeutic exercises, especially cervical stabilization exercises, are more effective for improving pain and neck disability than conservative treatment.

Purpose: The main causes of chronic neck pain (CNP) are wrong postures and degenerative changes. This study investigated the effects of specific exercise on elderly women with CNP. Methods: 29 elderly women who complain of CNP were classified into experimental group (14) and control group (15). The experimental group was treated with specific exercise and minimal conventional therapy, whereas the control group was treated only with conventional therapy. Then the effects on the visual analogue scale (VAS), neck disability index (NDI), self-rating anxiety scale (SAS), Korean form of geriatric depression scale (KGDS), and range of motion (ROM) were compared between the two groups. Results: The experimental group showed significantly improved results in VAS, NDI, SAS, KGDS, and ROM after intervention (p<0.05), as did the control group (p<0.05). The comparison of changes in the experimental group before and after intervention showed superior results in the SAS, NDI, and ROM (flexion, rotation, lat. flexion) results when compared with the control group (p<0.05). Conclusion: Specific exercise is effective in the improvement of SAS, NDI, and ROM for elderly women with CNP.
