Background: This study was planned to assess and compare the effectiveness of cervical region stabilization exercise and strengthening exercise on pain and range of motion in patient with chronic neck pain. Methods: Fifty-one patient with chronic neck pain were randomly allocated into strengthening and stabilization exercise (SSE) group (n=27) and Strengthening exercise (SE) group (n=24). The program was carried for 12 sessions, 3 days/week in 4weeks. Pain intensity with visual analog scale (VAS), cervical range of motion, deep cervical flexor strengthening were evaluated before and after the intervention. Results: After the program, pain intensity decreased in group SE and SSE were found (p<.05). Range of motion and deep cervical muscle strength increased in group SE and SSE were found(p<.05). The intergroup comparison showed that significant difference in range of motion and deep cervical muscle strength (p<.05). Conclusions: The study suggest that both SSE program and SE program might be a useful treatment for patients with chronic neck pain. However SSE program might be superior in improving cervical range of motion and deep cervical flexor strength compare to SE program.

Background: More women than men experience genu recurvatum, which can lead to knee pain and arthritis if left unattended. Pilates combined with taping is a suitable rehabilitation method for women with genu recurvatum. Objectives: To aimed the effect of taping and Pilates stabilization exercise on physical alignment and improvement of genu recurvatum in women with genu recurvatum. Design: A Randomized controlled trial. Methods: Twenty-one women were divided into three groups: taping group (back of knee taping and quadriceps femoris taping, n=7), Pilates exercise group (hip, knee and abdominal muscles exercise, n=7), and combined group (taping with pilates exercise, n=7). The measured variables were sagittal plane alignment and back and abdominal muscle, knee flexor and extensor strength. Results: After the intervention, all sagittal plane alignments were significantly improved in both the Pilates and combined groups. Sagittal plane alignment was significantly improved in the combined group compared with the taping group. Back and abdominal muscle strength were significantly improved in the Pilates and combined groups compared with the taping group. Knee flexor and extensor were significantly improved in the combined group compared with the Pilates group and in the Pilates group compared with the taping group. Conclusion: Pilates exercise with taping or Pilates exercise alone was effective intervention methods to improve physical alignment and strength in women with genu recurvatum.

Purpose: The purpose of this study was to investigate the exercise effect of two types of training with a recumbent cycle ergometer on ankle muscle strength (dorsiflexor strength, DFS; dorsiflexor strength/weight, DFS/kg; plantar flexor strength, PFS; and plantar flexor strength/weight, PFS/kg) in healthy male subjects. Methods: Twenty-three healthy males (27.91±8.66 yr) were randomly allocated into two groups (high-intensity interval training (HIIT), and aerobic exercise training (AET) after the first measurement. The subjects were trained for 24 sessions (40 min/rep, three times/week) and ankle strength was measured for a second time. Two-way mixed model analysis of variance (ANOVA) was used to identify significant differences between changes in ankle muscle strength between before and after training (within factors) in the HIIT and AET groups (between factors). The statistical significance level was set at α=0.05. Results: In both HIIT and AET groups, all variables of ankle muscle strength were significantly increased after training compared to before training (p=0.001). However, there were no differences in all variables of ankle strength between the HIIT and AET group (p>0.05). Conclusion: Both types (HIIT and AET) of recumbent cycle exercise training could be effective training methods to increase ankle muscle strength in healthy individuals, and the HIIT type with high intensity and low frequency pedaling could be recommended more to strengthen ankle muscles.

Background: This study was conducted in order to see if muscle strength is different according to fall experience in female elders by comparing their muscle strength of waist and knee, which is one of factors inducing fall. Method: For this study, 22 female elders aged over 65 sampled from senior centers in D City were surveyed on their fall experiences using a questionnaire asking clinical history. Then, 8 elders with fall experience (FE) and another 8 without (NFE) were selected and participated in the research. Isokinetic muscle strength was measured with isokinetic equipment BIODEX SYSTEM 3 PRO, and the peak torque was obtained from the highest of 9 measurements at angular velocity $60^{\circ}/sec$ according to the method recommended in the manual. Measured items were waist flexion and extension, and knee flexion and extension. Results: The FE group showed higher extensor and flexor muscle strength of the waist, but the difference was not significant (p<.05). In addition, no difference was observed in extensor muscle strength of the knee (p<.05). In flexor muscle strength, however, the FE group was significantly higher than the NFE group (p<.05). Conclusion: The application of regular exercise programs for improving muscle strength, endurance, etc. to those with fall experience will be effective in preventing falls among them.

이 연구의 목적은 사이클 선수를 대상으로 슬관절 등속성 근기능의 좌 우측 불균형이 무산소성 페달링 파워 관련 변인에 미치는 영향을 조사하는 것이다. 슬관절 등속성 근력 기준으로 비주측과 주측의 근력균형지수가 매우 균형적인 집단(High Symmetry Group, HSG), 적정수준의 집단(Moderate Symmetry Group, MSG), 불균형이 존재하는 집단(Asymmetry Group, AG)으로 분류하여 페달링 기능을 비교하였다. 그 결과 신근력의 비주측과 주측의 근력 불균형은 페달링 기능의 집단 간 차이점이 없었다. 한편, 굴근력의 비주측과 주측 근력균형지수의 불균형은 무산소성 페달링 파워 관련 변인에서 집단 간 차이점이 미세하게 존재하였지만, 페달링 기능에 부정적인 영향을 미치는 수준은 아닌 것으로 판단된다. 그러므로 좌 우측 근기능이 거의 동일하게 적용되는 사이클 선수에게도 근력 불균형이 존재하였으나, 이러한 불균형이 페달링 기능에 부정적인 영향을 미치지 않는 것으로 판단된다.

Background: Spinal Mobilization is one of the manual therapy technique that clinicians have used to treat pain, however, there is still a lack of research on changes in strength in healthy people. Objectives: To investigate the effect of posterior-anterior lumbar mobilization on lower limb strength in healthy individuals. Design: Two-group pretest-posttest design. Methods: In this study, 23 healthy subjects aged 20 years were assigned to 12 lumbar mobilization group (LMG) and 12 sham group (SG) to perform intervention and measurement through pre- and post-design. Intervention was performed in LMG with grade III~IV on L3-5 of the lumbar spine, and lumbar mobilization was performed for each segment. After intervention, knee flexion and extension strength were measured. To measure the main effect on muscle strength, a comparative analysis was conducted using paired t-test and independent t-test. Results: In LMG, knee flexor and extensor strength were increased significantly at 60°/s (P<.05). In addition, the extensors of LMG and SG were significantly different only at 60°/s, and the flexors were significantly different between groups at both 60°/s and 180°/s (P<.05). Conclusion: In healthy individuals, lumbar mobilization results in improvement of strength of knee flexor and extensor, and additional experiments on the effect of mobilization on the lumbar spine on functional changes in the lower limbs will be needed.

임상학적인 관찰에 따르면, 반복적인 하중에 의하여 뼈/건의 접합부분에 발생하는 부분적인 파손은 병리학적인 변화를 유발시킴으로 인하여 주관절의 상골과염(Epicondylitis)으로 발전시킬 수 있는 주요한 원인으로 간주되고 있다. 반복적인 하중이나 정적인 하중 하에서의 주관절에 위치한 신전건 및 굴곡건의 기계학적인 물성치와 파괴양상은 지금까지 잘 알려져 있지 않다. 본 연구에서는 상골과염과 직접적인 관계가 되는 신전건 및 굴곡건의 기계학적인 물성치인 파괴강도, 반복하중의 회수와 변형율(Strain)간의 연관관계 및 반복하중에 있어서의 생체조직학적 변화의 향상, 특히 파괴의 진행양상을 관찰하였다. 적용하중의 속도에 따르는 신전건 및 굴곡건의 파괴강도의 통계학적인 차이는 보이지 않고 있으나, 파괴강도에 있어서 신전건은 1199.0 N/$cm^2{\pm}$388.8, 굴곡건 1922.0 N/$cm^2{\pm}$764.4로, 굴곡건이 신전건에 비하여 1.6배 정도 크게 나타났으며, 상호간의 파괴강도에 있어서 통계학적인 차이가 있음을 보여주고 있다.(p<0.05). 조직학적 관찰에 의하면, 반복하중 하에서 뼈/건의 접합부분 특히 Uncalcified Fibrocartilage 부분에서 분리가 시작되었으며, 이는 상골과염을 발생시키는 주요생체조직부분이라는 것을 시사하고 있다.
