Type I, II, III are regarded as "true" joint receptors, type IV is considered a class of pain receptor. Type I, II and III mechanoreceptors, via static and dynamic input, signal joint position, intraarticular pressure changes, and the direction, amplitude, and velocity of joint movements. Type I mechanoreceptor subserve both static and dynamic physiologic functions. Type I are found primarily in the stratum fibrosum of the joint capsule and ligaments. Type I receptors have a low threshold for activation and are allow to adapt to changes altering their firing frequency. Type II receptors have a low threshold for activation. These dynamic receptors respond to joint movement. Type II receptors are thus termed rapidly adapting. Type II joint receptors are located at the junction of the synovial membrane and fibrosum of the joint capsule and intraarticular and extraarticular fat pads. Type III receptors have been found in collateral ligaments of the joints of the extremities. Morphologically similar to Golgi tendon organ. These dynamic receptors have a high threshold to stimulation and are slowly adating. Type IV receptors possess free nerve ending that have been found in joint capsule and fat pads. They are not normally active, but respond to extreme mechanical deformation of the joint as well as to direct chemical or mechanical irritation. Small amplitude oscillatory and distraction movements(joint mobilization) techniques are used to stimulate the mechanoreceptors that may inhibit the transmission of nociceptors stimuli at the spinal cord or brain stem levels.

This study examined the effect of the theratainment swiss ball exercise on the upper limb function, pain, and daily activities of a patient with axillary nerve injury. The research duration was from November 5^th, 2019 to February 25^th, 2020. The research subject was a 23-year-old female patient living in the metropolitan city of G in South Korea, and the A-B-A' type of single-subject experimental research design was used. In this study, repeated training was provided to the patient in the form of exercises employing different directions and gradually increased weights. The training increased the structural stability and mobility of the shoulder and was effective for pain relief as it strengthened shoulder function. The training helped the subject improve her posture change adaptability and reaction ability in different environments and ultimately enabled her to increase and maximize her performance of independent daily activities. This study thus demonstrated the positive effect of the Swiss ball exercise on the upper limb function, pain and disability, daily activities of a patient with axillary nerve injury and confirmed the potential of the exercise as an intervention method. Continued investigation to develop and test the effect of the Swiss ball exercise will be required for it to be used professionally as a therapeutic approach by occupational therapists in treating a variety of patients.

Osteochondritis dissecans is a common cause of lateral elbow pain in throwing athletes and gymnasts between the age of 10 and 15 years. The pain frequently is insidious and progressive in nature and is relieved with rest in most cases. Compressive forces at the radiocapitellar joint along with a tenuous blood supply to the region may play a role in the etiology of this condition. Treatment is directed according to presenting symptoms, radiographic findings and status of the involved segment. Surgical management involves either an excision of a loose lesion and removal of loose bodies or reattachment of an osteochondral fragment. The role of subchondral penetration of debridement of the defect after fragment excision is unclear. Whether to excise and debride or to fix an unstale fragment is a highly controversial topic. The clinician should recognize osteochondritis dissecans of the elbow as a potentially disabling condition where the prognosis for return to sport is guarded

Purpose: To report the clinical results of patients treated for a rupture of the distal tendon of biceps brachii Materials and Methods: Between February 1987 and March 2004, we treated 16 patients with a rupture of the distal tendon of biceps brachii. 9 of 16 patients underwent surgical treatment. All cases were male, median age was 26.3(range, 16-48) years. The mean interval between injury and surgery was 4.7 days (range, 1~36 days). Operative correction was performed anatomically, using the two-incision technique(3 cases) or one-incision technique(6 cases). Clinical outcomes were evaluated one year after operation by assessing the review about the physical examination finding and radiologic findings with surgical findings, range of motion, muscle strength, subjective satisfaction, activity and return to previous occupation. and via telephone interview in cases of conservative treatment. Results: In cases of surgical treatment, 85.8%, 86.3% of flexion-extension and supination-pronation motion than healthy side were measured respectively. 75% of flexion power than healthy side was measured. Eight of nine(89%) were very satisfied. Eightl of nine returned to original job. In cases of conservative treatment, 65% of flexion power than pre-injury state was reported. Four of seven were satisfied, two were dissatisfied, one was very dissatisfied. Three of seven returned to original job. Conclusion: Early anatomic reconstruction can restore more strength and endurance for supination and flexion range and power. Conservative management may be considered for partial injuries, but operative repair must be considered in complete rupture, athletes, patient with high activity.

Objective : The study was to investigate the neurophysiological approach to the effect of complex exercise on memory, one of brain functions, and the degree of sleep disorder using experimental animals with sleep disorders. Methods : This study carried out a complex exercise that designed in an animal laboratory for 4 days to 16 sleep - disordered model rats. After the exercise, brain function was confirmed with the changes of BDNF in the hippocampus and the change of sleep level was confirmed with the concentration of melatonin in the blood. Results : First, the effect of the complex exercise program on brain function was significantly increased in the experimental group(p<0.01). Second, the effect of complex exercise program on sleep disturbance was significantly increased in the experimental group and control group(p<0.01)(p<0.05). Conclusion : The rate of increase of the elderly in the community is rapidly increasing, and the sleep disorder of the elderly can affect the quality of life of these elderly people. Secondary memory impairment due to sleep disturbances can also be a problem. Although there are many ways to improve sleep disturbance, it has been scientifically proven through experimental animals that sleep and memory can be improved with complex exercise that is not economically, spatially burdensome.

Bruxism이란, 일반적으로 기능이외의 목적으로 상하악 치아를 악물거나 갈음질 하는 것이라고 정의된다. 동일한 상태를 서술하는 용어로 neuralgia traumatica, Karolyi effect, occlusal habit neurosis, parafunction 등이 있으며, 수면중의 이갈음질을 bruxism, 주간의 습관성 이갈음질을 bruxomania로 구분하기로 한다. 또한 centric bruxism과 eccentric bruxism으로 분류하기도 한다. eccentric bruxism은 통상적 의미의 수면중의 bruxism이며, 하악의 측방운동중의 이갈음질이고 뽀드득하는 갈음질 소리를 냄, 저작근육의 긴장도가 증가되어 있으면서 등장성수축을 나타내고, 비중심위의(eccentric) 교합간섭이 주요 유발인자인 반면에 centric bruxism은 중심교합위에서 상하악 치아를 간헐적으로 악무는 것(clenching)은 의미하고 - 지속적으로 악무고 있는 것은 clamping이라고 함.- 주로 주간에 행하며 갈음질소리를 들을 수 없고, 역시 저자근육의 긴장도가 증가되어 있으며 등률성수축을 나타내고, 중심교합위에 근접하여 존재하는 교두간섭이 유발인자이다. bruxism이나 clenching과 부정교합의 관계는 bruxism과 clenching은 부정교합을 야기할 수 있고, 부정교합도 역시 bruxism과 clenching을 유발시키는 작용을 할 수 있는 악순환적 관계이다. 현저한 부정교합을 가지고 있는 bruxism환자의 교정치료는 그 목적이 bruxism의 치료라기보다는 오히려 부정교합의 치료이며 부차적으로 bruxism의 치료를 기대하게 된다. 그러나 bruxism이 장기간 지속되어 치아 및 그 주위조직, 악관절과 신경근계에 심한 손상을 주었을때의 교정치료는 일반적으로 제한을 받을 뿐만아니라 bruxism의 처치에는 거의 무의미한 치료가 될 수 있다. 따라서 거자는 bruxism 환자의 교정치료라는 제목의 원고 청탁을 받았으나 편집위원의 양해아래 장치를 이용한 bruxism의 치료에 관하여 서술하려 한다.

Purpose: The purpose of this study was to suggest an appropriate treatment method by comparing nonsurgical treatment and surgical treatment for enchondroma in the hands and feet. Materials and Methods: Seventy four cases with enchondroma of the hands and feet from January 1996 to March 2017 were selected to evaluate the functional outcomes. Thirty cases were treated with nonsurgical treatment, and 44 cases were treated with surgical treatment, such as curettage only or curettage with a bone graft. The mean follow-up period was 18.1 months. The functional results were analyzed using the Wilhelm and Feldmeier formula. Results: The mean age was 38 years, and the age range was between eight and 69 years. According to the Wilhelm and Feldmeier formula, the mean score of hand enchondroma was 3.09±0.85 and 3.20±0.91 in the non-operative and operative group, respectively. The mean scores of the foot except for the grip strength were 2.57±0.79 and 2.75±0.50, respectively. No significant difference was observed according to the functional results. Among the 18 cases of enchondroma with pathological fractures, nine cases were treated non-surgically and nine cases were treated by surgically. In all 18 cases, complete bone healing was observed at the final follow-up. Conclusion: Relatively satisfactory results were obtained in both surgical and nonsurgical treatment and there was no significant difference in functional outcomes. In cases of enchondroma in the hands and feet, nonsurgical treatment can also be a good treatment option.

Exercise programs conducted for people with stroke disabilities tend to be monotonous as they are mainly focused on therapeutic effects in the form of physical therapy performed in hospitals. However, the news sports program conducted in this study is thought to deform the intensity and difficulty of exercise in consideration of the exercise ability of each subject and to participate safely and interestingly to use equipment made of special materials. The purpose of the present study was to understand new sports program participation experiences in people with stroke. The qualitative data on eleven participants' new sports program participation experiences were acquired through in-depth interviews. As a result of the study, four subcategories (expectations for the program, experience in participating in the program, and program improvement plan) and ten core concepts were derived. Based on the results of this study, the new sports program for people with stroke living in the community after discharge is expected to be the basis for the development of community-based exercise programs considering the characteristics of stroke.
