Purpose : This paper reviews on the method of PNF stretching. Methods : This is literature study with Pubmed, medline, SPORT Discus, EBSCO, ProQuest and books. Results : PNF stretching is effective for increasing range of motion than static and ballistic stretching. CR(contract-relax) technique is effective and CRAC(contract-relax with agonist contraction) technique including agonist contraction is more effective. A minimum of one repetition, twice or three times per week is required for range of motion gains, needs to be conducted continueously. A minimum of 20% contraction intensity and more than 3 seconds contraction duration are needed to increase range of motion. Inclusion of static stretching of antagonist and agonist contraction is more effective. Conclusions : PNF stretching is more effective for increasing range of motion than other stretching methods, but, clinicians need to select proper techniques according to subjects and muscles, and conduct carefully when applying technique.

In this paper, we propose new adaptive search range motion estimation methods where the search ranges are constrained by the probabilities of motion vector differences and a search point sampling technique is applied to the constrained search ranges. Our new methods are based on our previous work, in which the search ranges were analytically determined by the probabilities. Since the proposed adaptive search range motion estimation methods effectively restrict the search ranges instead of search point sampling patterns, they provide a very flexible and hardware-friendly approach in motion estimation. The proposed methods were evaluated and tested with JM16.2 of the H.264/AVC video coding standard. Experiment results exhibit that with negligible degradation in PSNR, the proposed methods considerably reduce the computational complexity in comparison with the conventional methods. In particular, the combined method provides performance similar to that of the hybrid unsymmetrical-cross multi-hexagon-grid search method and outstanding merits in hardware implementation.

PURPOSE: The respiratory function and range of joint mobility deteriorate due to aging, respectively, and the respiratory function may be related to the range of joint mobility. To the best of the authors' knowledge, there has been little research on how the deterioration of the range of joint mobility caused by aging is related directly to the respiratory function. This study investigated the relationship between the respiratory function and the range of joint motion in the cervical and lumbar regions of older adults. METHODS: Thirty-two older adults participated in the study. The forced vital capacity (peak expiratory flow: PEF and forced expiratory volume in 1 second: FEV1) and the range of cervical joint motion were assessed in all subjects. The results were analyzed using the Pearson's correlation coefficient. RESULTS: The respiratory function moderately correlated with age. A moderate correlation was observed between FEV1 and right cervical lateral flexion. PEF was moderately correlated with the lumbar lateral flexion. In addition, FEV1 correlated strongly with lumbar lateral flexion. CONCLUSION: The respiratory function was correlated with the cervical and lumbar lateral flexion. Therefore, rehabilitation of the respiratory function should involve improving the limited range of motion of the joints, and a stretching program is needed for older adults.

The purpose of this study was to find the effects of the lumbar stabilizing exercise on the isometric lumbar extension strength and the range of motion of lumbar extension. 16 healthy subjects were recruited (9 males, 7 females, mean age 25${\pm}$3.2). They performed 5 types of exercises 5 times per week for 4 weeks. We evaluated isometric trunk extension strength (0, 12, 24, 36, 48, 60, $72^{\circ}$) by MedX(Ocala, FL) and measured range of motion of lumbar extension. All measurements were measured at pre-exercise and 4 weeks post-exercise. The results of this study were summarized as follows; After 4 weeks of exercise, isometric lumbar extension strength was generally increased but there were only significant differences at $12^{\circ},\;24^{\circ},\;48^{\circ}$. The range of motion of lumbar extension was increased (p<.05). The isometric lumbar extension strength correlated with the range of motion of lumbar extension. In conclusion, our results have shown that lumbar stabilizing exercise influenced both lumbar extension strength and range of motion of lumbar extension.

The purpose of this study is to experimentally analyze swing motion with soft golf clubs and compare with that with normal golf clubs. Soft golf is newly devised recreational sport based on golf but focus on the playability for the elderly. The subject fur the experiment performed swing motion using a normal golf club and a soft golf club in turn. The swing motion of the subjects was tracked using an opto-electric three-dimensional motion analysis system. The results were compared against those obtained with a normal golf club. The range of motion was analyzed along with top head speed for two cases. It was found that higher club head speed could be achieved with reduced range of motion at lumbar joint using soft golf club when compared against the swing using regular club. The lower range of motion fur lumbar bending means reduced risk of injury at the joint. So, it is projected that we can reduce the risk of injury with soft golf while maintaining the club head speed.

Purpose: The purpose of this study is to investigate the effects of interference current therapy and laser therapy on functional recovery after total knee arthroplasty by measuring the Berg balance scale and range of motion. Methods: Subjects were 30 patients who were admitted to G Hospital after total knee arthroplasty. They were randomly assigned to experimental group I in which interference current therapy was applied (n=10), experimental group II in which laser therapy was applied (n=10), or the control group (n=10). The Berg balance scale and range of motion of the subjects were measured before, after 2 weeks, and after 4 weeks of therapy. Results: There was a statistically significant change (p<0.05) in the Berg balance scale and range of motion before and after therapy intervention among the laser therapy group and the interference current therapy group. There was also a significant change between the groups in the Berg balance scale and range of motion. Tukey's post hoc comparison showed a statistically significant difference between the control group and experimental group I and between the control group and experimental group II (p<0.05). Conclusion: The application of interference current therapy and laser therapy resulted in a significant change in both the Berg balance scale and range of motion among patients with total knee arthroplasty. The findings of this study can be used as preliminary clinical data in evaluating functional recovery in patients with total knee arthroplasty in a post-clinic setting.
