영상처리 기술은 현대 사회에서 다양한 분야에 응용될 수 있다. 현대인들이 관심을 가지고 있는 헬스케어도 그 분야 중 하나이다. 운동기구등을 가지고 하는 헬스케어는 정확한 동작이 우선시 되어야 하는데, 일반인들은 비용의 문제 등으로 혼자서 운동을 하고 있는 실정이다. 이러한 경우에는 운동의 효율성을 보장할 수 없고, 때에 다라서는 운동자에게 역효과가 나기도 한다. 본 논문에서는 영상처리 기술을 이용하여 일반인이 혼자서 운동을 할 때 자세를 잡아 주고 교정해 주는 프로그램을 개발하였다. 사용자들은 운동 시 본 프로그램을 통하여 정확한 자세를 가르치는 개인트레이너를 고용하는 효과를 얻을 것으로 기대한다.

PURPOSE: This study aimed to compare the effects of manual therapy with stabilization exercises to manual therapy alone, on neck pain and body functions in patients with chronic mechanical neck pain. METHODS: Twenty patients with chronic mechanical neck pain were recruited and randomly allocated into two groups. A control group(n = 10) was given the manual therapy alone and an experimental group(n = 10) was given the manual therapy with stabilization exercises. The intervention was carried out 3 days per week for 4 weeks. The cervical resting pain, the most painful motion pain, craniocervical flexor endurance, forward head posture and neck disability index were used to assess participants at baseline and after 4 weeks. RESULTS: A comparison of the parameters before and after the intervention showed that both groups experienced significant improvements in the resting pain, the most painful motion pain, craniocervical flexor endurance, and forward head posture except for the forward head posture in the control group. A comparison of the parameters between the groups did not show a significant difference. CONCLUSION: The results of this study suggest that the combined intervention of manual therapy with stabilization exercise does not seem to be more effective than manual therapy alone for improving neck pain, craniocervical flexor endurance, forward head posture, and the neck disability index in patients with chronic mechanical neck pain.

To examine the changes in pain, the severity of the neck disorder, craniovertebral angle, and muscle activity in young adults with forward head posture. 37 "N" University students in their 20s with forward head posture, including both male and female participants. Measurement of pain, NDI (neck disorder index) craniovertebral angle, and muscle activity were taken before and after the 6 week intervention period. The pain was measured using the visual analog scale. The severity of the neck disorder was measured using the NDI The craniovertebral angle was measured by taking a photo. The muscle activity was measured using surface electromyography. Neck posture correction exercises paired with proprioceptive training is the most effective intervention for reducing pain. Both neck posture correction exercises paired with Kinesio taping or proprioceptive training are effective interventions for addressing neck disability, craniocervical angle, and muscle activity. Neck posture correction exercises paired with Kinesio taping or proprioceptive training are more effective at addressing pain, neck disorder, craniocervical angle, and muscle activity than performing the neck posture correction exercises alone.

Purpose: The purpose of this study is to acknowledge the effects that have the strength exercise done only on the neck extensor, only on the thoracic extensor, and both the neck and the thoracic extensor on forward head posture(FHP) and cervical range of motion. Also is to discover which of the exercise is the most effective. Method: This experiment will be done by selecting 40 people who have 16cm or more FHP and they will be divided into four groups: three experimental groups and a control group. The first experimental group will do only the neck extensor strength exercise(NESE). The second experimental group will do only the thoracic extensorstrength exercise(TESE) and the third experimental group will do both the NESE and the TESE. The experimental groups will make a day three times each ten sets of extensor isometric strength exercise but the time will be increased from 4 to 6 and8 seconds until it will be done the ten sets. Then after four weeks, they will be compared which had the best results for the FHP and the cervical range of motion. Result: After the experiment, it was compared the experimental groups with the control group. Every experimental group had an improvement on their FHP and cervical range of motion. However, the only NESE and the only TESE did not have a significantly difference(p>.05). Only the group who did both the NESE and the TESE had a sign ificantly improvement compared to the control group. Conclusion: 1. The only NESE and the only TESE seem that had a positive effect on FHP and cervical range of motion. However, it cannot be conclude that it is effective. 2. When both the NESE and the TESE are done, it is showed statistically a significant difference(p<.05) on FHP and cervical range of motion. The refore, it would be note worthy if this exercise is used to improve the FHP and the cervical range of motion.

PURPOSE: The aim of this study was to provide evidence for the treatment of Forward Head and Rounded Shoulder Posture (FHRSP) using posture correction exercises by comparing muscle activity and onset time around the neck and shoulder area during an arm elevation task. METHODS: The subjects were divided into FHRSP (21 persons) and non-FHRSP (19 persons) groups to measure muscle activity and onset time of muscle contraction. Wireless surface electromyography was used to assess the muscle activity and onset time of the right and left sternocleidomastoid (SCM), splenius capitis, anterior deltoid, middle deltoid, serratus anterior, upper trapezius, pectoralis major, and infraspinatus during an arm elevation task. After the pre-measurement, the participants performed the postural correction exercises, and then the post-measurement was conducted. RESULTS: After the posture correction exercises, there were significant differences in the muscle activity and onset time of all muscles in the FHRSP group. The results of the comparison of the muscle onset time during an arm elevation task demonstrated that after the postural correction exercises, the muscle onset time was significantly reduced in the right and left SCM and left splenius capitis, but there were no significant changes in the onset time of other muscles. CONCLUSION: The results of this study help us understand the change in muscle activities and muscle contraction onset time in a person with FHRSP when lifting the arm and suggest the relevant basis to apply the posture correction exercise in clinical settings.

PURPOSE: The aim of this study was to investigate the effect of scapular dynamic taping on pain, disability, upper body posture, and range of motion (ROM) in the postoperative shoulder. METHODS: Twenty-two patients who underwent acromioplasty and rotator cuff repair surgery volunteered for this study. The subjects were randomly divided into an experimental group (EG, n=11) and a control group (CG, n=11). For the EG, exercise therapy, manual therapy, and scapular dynamic taping were applied for 6 weeks; for the CG, only exercise therapy and manual therapy were applied for 6 weeks. Shoulder pain, disability, upper body posture, and ROM were evaluated at baseline, after 3 weeks of intervention, and after 6 weeks of intervention. Assessment tools included quadruple visual analog scale (QVAS) for level of pain; shoulder pain and disability index (SPADI) for functional disability level; forward head angle (FHA), forward shoulder angle (FSA), and pectoralis minor index (PMI) for upper body posture; and ROM testing. RESULTS: Significant differences were observed between the EG and CG in SPADI total scores; internal rotation and external rotation ROM of the glenohumeral joint ; FSA ; and PMI. All groups showed statistically significant improvement in QVAS; SPADI; flexion; abduction; external rotation and internal rotation ROM of the glenohumeral joint; FSA; and PMI. CONCLUSION: These results suggest that, for patients who have undergone acromioplasty and rotator cuff repair surgery, the addition of scapular dynamic taping during therapy is effective for improvement of shoulder disability level, ROM, and upper body posture.

Purpose : Various studies effects of mental practice. However, there is a lack of research on the effects of practice on postural alignment. Therefore this study to the effect of ankle exercise combined with mental practice on postural alignment of legs. Method : Subjects were randomly assigned to mental practice group (experimental group n=15) and general exercise group (control group n=15). Postural alignment was the hip, knee, and ankle joints. When viewed from the side, an arbitrary point in front of the malleolus makes a straight line with the plumb line. Exercise was performed a week for weeks. Exercise programs included muscle strengthening, relaxation, and proprioception exercise. The experimental group mental practice. Result : Both groups showed significant differences in postural alignment ankle joint, knee joint, and hip joint. In particular, the experimental group showed a larger change than the control group. However, significant difference in postural alignment change only the knee joint (p<0.05), and there was no significant difference the hip joint (experimental group=$0.77{\pm}0.81$, control group=$0.87{\pm}1.13$) and ankle joint (experimental group=$0.52{\pm}0.63$, control group=$0.48{\pm}0.41$). Conclusion : This study suggests that mental practice is effective as an exercise method postural alignment. Mental practice also expected to be musculoskeletal disorders. Therefore, additional studies should be conducted to verify the effect of mental practice on the alignment of various parts.

Background: Cervical dysfunction is a common pathomechanical marker in individuals with forward head posture (FHP). To overcome the limitations of the isometric chin-tuck (ICT) exercise, dynamic neuromuscular stabilization (DNS), which emphasizes an entire spinal chain exercise, has recently shown promising clinical results. Objects: Purpose of this study was to compare the immediate effects between ICT and DNS techniques. Methods: 43 young subjects (mean age, $24.0{\pm}5.0$ years) were recruited. Group of subjects with FHP were measured under baseline, ICT, and DNS conditions. Outcome measures included sitting height, longus colli (LC) and sternocleidomastoid (SCM) muscle thickness and LC/SCM thickness ratio. One-way repeated measures ANOVA was used to compare the continuous dependent variables among FHP, ICT, and DNS conditions at p<.016. Results: Both ICT and DNS exercise conditions yielded significantly increased LC muscle thickness, LC/SCM thickness ratio and sitting height than did FHP condition (p<.0001, respectively). Sitting height was significantly greater in DNS exercise than in the ICT exercise (p<.0001). Conclusion: The present results demonstrated that sitting height was greater in the DNS exercise than in the ICT exercise, as well as both corrective postural training exercises were effective on LC/SCM muscle balance ratio when compared with the baseline FHP condition. Therefore, it is considered that DNS exercise can be the recommended exercise for people with FHP.

Purpose : The purpose of this study was compared for rounded scapular between strechting on pectoralis minoor and strengthening on scapular stabilizer muscles. Methods : The main laboratory had an experiment of the exercise for rounded shoulder posture with 30 patients on a pectoralis minor stretching and scapula to stabilize the elastic band to divide into two groups in this study which were conducted. Results : Acromial height measured from changes of the rounded shoulder posture changes before and after workouts; stretching before exercise in the exercise group is from $94.19{\pm}3.47$ to after result of $94.84{\pm}3.19$, and the after exercise of an elastic band pre-exercise in the exercise group is from $93.60{\pm}3.42$ to $88.68{\pm}3.49$, dividing into two groups, which increased significantly. Compared to an acromial height variation results before and after workouts; stretching exercise group made $3.07{\pm}1.43$, $4.91{\pm}2.24$ and elastic band exercise group, $4.91{\pm}2.24$, which shows the difference between the two groups and was not statistically significant. Conclusion : Against a pectoralis minor that cause the findings of this study, RSP proximately shows serratus anterior and the strengthening of trapezius by exercises of the shoulder peaks which decrease in height arbitration scheme of a pectoralis minor stretching effect as shown. Therefore, it is expected RSP patients in clinical intervention methods combined with stretching exercises strengthens muscles against an elastic band exercise effective.
