Objective: This study was carried out to compare changes in pain, swelling and range of motion (ROM) between the two groups according to physical therapy intervention. Design: Randomized controlled trial. Methods: There were a total of 20 elderly subjects ages 65-75 years old who have been admitted to the hospital for a total knee arthroplasty. After surgery, the experimental group (n=10) carried out quadriceps femoris muscle strengthening exercise, hamstring stretching exercises and gastrocnemius stretching exercise with a physical therapist for 30 minutes and additionally, received ice pack therapy for 20 minutes once a day. The control group (n=10) carried out continuous passive motion for 30 minutes and received ice pack therapy for 20 minutes once a day. The experimental group and control group carried out each intervention program for 2 weeks 3 times a week. The Visual Analogue Scale was used to assess pain, tape measurements were taken to assess swelling, and a steel goniometer was used to assess knee joint ROM. Results: As a result, the experimental group showed a statistically significant decrease in the pain and swelling, and a significant increase in knee flexion ROM after the intervention, compared to the control group (p<0.05). There was a significant improvement in pain, edema, and knee flexion and extension ROM in all subjects after intervention (p<0.05). Conclusions: According the results of this study, exercise in the experimental group is effect on the pain, swelling and ROM for total knee arthroplasty.

Purpose: The purpose of this study was to review articles in order to establish optimal contraction intensity and duration in the performance of relaxation techniques for maximal increase in range of motion. Methods: The Cochrane, EBSCO, Embase, Medline, ProQuest, PubMed, ScienceDirect, and Scopus databases were used to search articles from 1990 to January 2016. The search terms were "contract relax," "hold relax," "muscle energy technique (MET)," and "proprioceptive neuromuscular facilitation (PNF) stretching." Only experimental human studies (randomized controlled trials) that compared the effects of varying intensity and duration of isometric contraction were included. Non-English language and unpublished studies were excluded. Results: A total of 2,156 articles were initially identified, with only five eventually meeting the inclusion and exclusion criteria. Three studies compared the effects of varying intensity in isometric contraction and two studies compared the effects of varying duration in isometric contraction with regard to range of motion (ROM). Two articles suggested that submaximal voluntary isometric contraction was more effective than maximum voluntary isometric contraction (MVIC) in the improvement of ROM. One article showed that a longer contraction time led to greater increases in ROM. Conclusion: Submaximal voluntary isometric contraction was recommended during contract-relax exercises in healthy people. Lack of evidence makes it difficult to suggest the optimal duration of isometric contraction during relaxation techniques. For future research, high-quality evidence will be needed to establish the optimal contraction intensity for maximum improvement of ROM.

Purpose : The purpose of this study was investigated to find the approach in the PNF and TC for frail elder Method : This is a literature study with books, articles, seminal note and books for PNF and TC international course. Result : Neural mechanisms contribute significantly to the gains that occur in the range of motion about a joint with stretching exercises. The participation in a stretch-training program decreases tonic reflex activity and increases flexibility and decreases in force production and muscle activation. Also the stretching-induced decreases may be due to a central nervous system inhibitory mechanism. PNF stretch techniques can increase ROM in older adults. These results may differ from those of studies performed with younger populations because of age-related physiologic changes. TC exercise improves balance control and muscle strength and were associated with reorganized lower extremity neuromuscular patterns. Conclusions : The stretch training program of the PNF and TC contribute to increase the balance and coordination for frail elder. Therefore, The frail elder prevent falling. Further study, The PNF and TC be introduced as the new therapeutic intervention for frail elder.

In this paper a cervical rehabilitation robot for Mckenzie exercises to be effective to neck pain relief is proposed. The robot has two degrees of freedom (DOF) for Lateral flexion and extension, Dorsal and Vental flexion which enable user to perform cervical stretching and isometric exercises for neck muscles. The mechanical parts of the cervical rehabilitation robot can be mounted on a back- or head-rest of chair, and user can perform the Mckenzie exercise with seated. In experiments we measured the range of motion of cervical part, EMG signals from neck muscles and the contact forces of a head bracket fixing the head part of user, and then evaluated their performances. From the experimental results, we showed a feasibility of the cervical rehabilitation robot proposed in this study.

A Literatur Review of Physical and Breathing Exercises for Ear Health, the results were as follows. 1. The most common using way is rubbing your ears and auricle with warm palms. 2. To stimulate inner acoustic meatus, obstruct external acoustic meatus for a short time by the palm or fingers and then to stimulate it by the sudden opening. 3. This method is a common way to press aurical or orifice of external acoustic meatus for example, TE21(耳門), TE20(角孫), GB2(聽會), TE19(노息), TE18(계脈), GB11(竅陰), TE17(예風) etc. 4. The best time to pratice is early in the morning or before go to bed, but a litter difference by the writer's opinion, so there is not consistency. 5. Since tinnitus and hardness of hearing is related to the who1e body, it is known that you can relax your whole body by pressing the acupuncture points located in the head of occipital region or by stretching the upper half of the body. 6. There is method that obstruct your ears with palms and 3rd finger on your occipital region and splash by the 2th fingers.(sound the celestial drum)

Objective: Musculoskeletal neck pain have many symptoms which include decreased range of motion (ROM) and muscle strength, and increased pain. However, the management methods are controversial. The purpose of this study was to examine the effects of three interventions on ROM, strength, and pressure pain threshold (PPT) with musculoskeletal neck pain. Design: Pretest-posttest design. Methods: Thirty subjects participated in this experiment. They were randomly assigned to thefollowing groups: passive stretching (PS) group (n=10), massage (MASS) group (n=10), and muscle energy technique (MET) group (n=10). The treatment were applied bilaterally on the upper trapezius. The PS was applied 3 times for 30 seconds each time. The MASS was applied using two different techniques for 2 minutes per technique. For MET, the subjects performed 2 sets of 3 repetitions of isometric resistance exercise that was maintained for 10 seconds, followed by 10 seconds of rest. ROM, strength, and PPT parameters were measured after intervention. Results: In the MASS group, there was a significant improvement in all outcomes except for muscle strength (p<0.05). In the MET group, ROM and strength significantly improved compared to the pre-treatment results (p<0.05). As result of measuring the amount of change in each group, there was a significant difference in ROM (flexion) in the PS group compared with the MASS and MET group, a significant difference in strength in the MET group compared with the PS and MASS groups, and a significant difference in PPT in the MASS groups compared with the PS and MET groups (p<0.05). Conclusions: This study showed that PS, MASS, and MET are effective methods for improving ROM, strength, and PPT for musculoskeletal neck pain. Therefore, various therapeutic interventions for improving ROM, strength, and pain are suggested.

Objective: The purpose of this study was to examine the effectiveness of pelvic displacement when self-hamstring muscle stretches were applied to persons with low back pain. Design: Three-group pretest-posttest design. Methods: Forty persons with low back pain participated in this study. Pelvic tilt angle, hamstring flexibility, Quadruple Visual Analogue Scale (QVAS), Fear Avoidance Beliefs Questionnaire (FABQ), Korea version of the Oswestry Disability Index (KODI) and pelvic mobility were measured at pre-post. All participants were divided into either the pevic anterior tilt group (PAT group, n=12), pelvic midrange group (PMR group, n=18), or the pelvic posterior tilt group (PPT group, n=10). Self-stretching was performed using the pilates ring three times a week for a total of four weeks and the post-test was conducted and compared with the pre-test. Results: Hamstring flexibility, QVAS, KODI scores were significantly different compared to before the intervention (p<0.05). The changes in hamstring flexibility of the three groups were significantly different (p<0.05). Changes in KODI and FABQ results of the three groups were not significant. The pelvic posterior tilt range were significantly different in the PMR and PPT groups (p<0.05). The pelvic anterior tilt ranges showed significant differences after stretching in the PPT group (p<0.05). Conclusions: A large amount of change of hamstring flexibility, pelvic mobility of anterior and posterior tilt test in the PPT group was observed. Furthermore, therapists should consider pelvic displacement of the participant when applying intervention, which may, accordingly, have different effectiveness.

Objective: Jump training helps increase the muscle power by improving the muscle strength and reaction time of the muscle in operation. The purpose of this study was to identify the effects of strengthening, stretching exercise and meditation on electromyographic (EMG) onset timing of rectus femoris and gastrocnemius muscle during vertical jump performance. Design: Cross-sectional study. Methods: Ten healthy adults (5 male and 5 female) who were familiar with the vertical jumping task and had no lower extremity injuries or any bone or joint disorders, were recruited for this study. Muscle onset timing was measured by surface EMG. After EMG onset timing were measured during performing three baseline vertical jump trials, strengthening and stretching exercises of the rectus femoris and gastrocnemius, and meditation were performed in random order. EMG onset timing was measured during vertical jump after intervention, respectively. EMG value was averaged for the three trials and analyzed using one-way repeated ANOVA. Results: During vertical jump, EMG onset timing of gastrocnemius was a significant difference after intervention (p<0.05), and then there was significantly faster in strengthening exercise than meditation (p<0.05). Conclusions: These results indicate the potential positive effect of performing strengthening exercise of the gastrocnemius before a jumping event. Future research is required to identify the effects of intervention over a long period.

PURPOSE: The purpose of this study was to investigate the effects of stage-based training, including core exercises, on scoliosis patients. METHODS: Two patients with scoliosis participated in the study. Both patients participated for eight months and were trained for an hour three times a week. The training program consisted of stretching and strengthening, as well as core exercises, and was divided into five stages. The Cobb angles and trunk lengths of the subjects were measured after one month, two months, and four months of training. Measurements were also taken after the subjects completed training. All of the measurements were taken using Formetric 4D. RESULTS: The Cobb's angle of subject A, which was $41^{\circ}$ before training, measured $30^{\circ}$ following training. The Cobb's angle of subject B also improved from $41^{\circ}$ prior to training to $34^{\circ}$ after training. Furthermore, the trunk lengths of both subjects improved. The trunk length of subject A increased from 438 mm to 450 mm and, and the trunk length of subject B increased from 433 mm to 458 mm. CONCLUSION: This study has shown that stage-based training and core training can be used as effective treatments for scoliosis patients.

Background: The purpose of this study was to compare and analyze the effects of neck and trunk combined exercise program and single exercise on neck angle and neck and shoulder muscle activity. Design: Randomized controlled trial. Methods: In the single exercise group, the basic stretching, head bending and neck bending exercises were performed. The neck and trunk combined exercise group performed torso strength and trunk stability exercises to stabilize the trunk, and then performed the same neck exercise as the single exercise group. The exercise program was conducted 5 days per week for 2 weeks. One-way repeated ANOVA was used to investigate the statistical analysis of neck angle, neck and upper and middle trapezius muscle activity. Results: 1) There was no significant difference in neck angle degree after exercise in neck single exercise group. 2) In the neck and trunk combined exercise, the neck angle degree decreased continuously with the increase of the experimental period and showed a significant difference. 3) In the single exercise group, the muscles which showed significant difference compared to the post-exercise were the right upper, left and right middle trapezius. 4) In the neck and trunk combined exercise group, the right neck muscles showed significant difference after the exercise before the experiment. Conclusion: It was found that the neck and trunk combined exercise was more effective in reducing neck angle and the muscle activity of the subjects with forward head posture was decreased and increased. However, both exercises showed positive effects.
