The number of joint disease patients is increasing every year. Currently, the most CPM(Continuous Passive Motion) equipment uses expensive imported equipment, and one CPM equipment is designed to be used only in one joint, medical personnel or hospitals who are the main users of the medical equipment need to have several types of CPMs for joint rehabilitation. To solve this problem, this paper designed a multifunctional joint medical equipment that enables rehabilitation of knee, shoulder, and elbow joints in one CPM equipment and includes general, intensive, and adaptive exercise functions for effective treatment according to the patient's condition. The patient's condition was diagnosed using a load cell and a current sensor. In this paper, effective rehabilitation methods were presented and high reliability and precision of medical equipment was confirmed through experiments using potentiometer, encoder, and PI controller.

Objective: The purpose of this study was to measure the immediate effect of hip hinge exercise stretching on hamstring flexibility, pelvic tilting angle, proprioception, and dynamic balance in individual with tightness of the hamstring. Design: A randomized controlled trial. Methods: A total of 35 healthy young adults (27 males, 8 females) volunteered for this study and randomly divided into three groups (Hip hinge exercise stretching group, passive stretching group, and PNF stretching group). The hamstring flexibility, pelvic tilting angle, knee joint proprioception, dynamic balance was conducted for 3 times. In order to evaluate the hamstring flexibility, the active knee extension test was performed. Forward bending test was performed to examine pelvic tilting angle.The proprioception was tested by the joint position sense test and dynamic balance was evaluated by Y balance test. Results: The hamstring flexibility, pelvic tilting angle and dynamic balance were significantly improved between three groups before and after intervention (p<0.05). Dynamic balance was significantly difference between the three groups in the posterolateral direction (p<0.05). Conclusions: This study result showed that hip hinge exercise stretching was the most effective method for increasing hamstring flexibility, pelvic tilting angle and dynamic balance. In addition, it is necessary to study whether hamstring stretching is effective in low back pain patient with hamstrings tightness.

The purpose of this study was to analyze the changes in muscle fatigue by using electromyography (EMG) measurements of the median frequency of shoulder muscles of patients who underwent rotator cuff repair, and to provide basic data for efficient exercise methods during rehabilitation after the repair. In the study, 24 male and 8 female patients who underwent rotator cuff repair performed continuous passive shoulder joint motion for 3 weeks and the median frequency of their shoulder muscles before and after the repair were compared using measurements by EMG. The infraspinatus, supraspinatus, and serratus anterior muscles showed significant differences in the changes in the median frequency before and after the repair. Significant differences were also found in the median frequency of the three muscles both before and after the repair. Additionally, the middle deltoid muscle had a lower median frequency than the supraspinatus muscle before the repair and the infraspinatus muscle had a lower median frequency than the middle deltoid muscle after the repair. It is expected that these results will serve as important data in developing rehabilitation exercise programs for the infraspinatus, supraspinatus, and serratus anterior muscles by compensating the middle deltoid muscle with the lowest muscle fatigue after the rotator cuff repair erase.

PURPOSE: Balance exercise as well as lower extremity strengthening exercise (LESE) is known to be effective in patients with knee osteoarthritis (KOA). The purpose of this study was to investigate the effectiveness of performing LESE in conjunction with balance exercise on lower extremity function, range of motion, muscle strength, and balance in patients with KOA. METHODS: The subjects of this study were 25 patients with KOA who were recruited and randomly divided into two groups: 1) those who performed LESE with balance exercise; and 2) those who performed only LESE. Both the groups also received general physical therapy and performed aerobic exercise. The interventions were performed 3 times a week for 4 weeks. To determine the effectiveness of the interventions, we measured Western Ontario and MacMaster Universities Arthritis Index (WOMAC) score, numerical rating scale (NRS) score, passive range of motion (PROM), chair stand test (CST), and Berg Balance Scale (BBS) score at the initiation of the interventions and again after 4 weeks, at the time of completion of the interventions. RESULTS: After 4 weeks of the interventions, both the groups showed significantly improved WOMAC (p<.01), NRS (p<.01), PROM (p<.05), CST (p<.05), and BBS (p<.01) scores. However, there was no significant difference between the groups in terms of the clinical outcomes observed. CONCLUSION: These results suggest that the addition of balance exercise to a LESE regimen in patients with KOA did not provide any additional benefit.

Background Several techniques have been designed to treat fifth metacarpal fractures reported to be effective. However, these methods cannot be easily applied to the fourth metacarpal due to its central anatomical position. In this study, we sought to analyze the functional outcomes of patients who underwent transverse pinning for a fourth metacarpal bone fracture. Methods A total of 21 patients were selected and their charts were retrospectively reviewed. After fracture reduction, two transverse Kirchner wires were first inserted from the fifth metacarpal to the third metacarpal transversely at the distal part of the fractured bone, and then another two wires were inserted at the proximal part of the fractured bone. The splint was removed approximately one week postoperatively and the Kirchner wires were removed four to five weeks postoperatively. Patients started active and passive exercise one week after the operation. Pain visual analog scores, total active and passive motion, and the active and passive range of motion of the metacarpophalangeal joint and grip strength were evaluated. Results Dorsal angulation improved from a preoperative value of $44.2^{\circ}$ to a postoperative value of $5.9^{\circ}$. Six weeks after surgery, functional recovery parameters, such as range of motion and grip strength, had improved to 98% of the function of the normal side. No major complication was observed. Conclusions We suggest that the transverse pinning of fourth metacarpal bone fractures is an effective treatment option that is less invasive than other procedures, easy to perform, requires no secondary surgery, minimizes joint and soft tissue injury, and allows early mobilization.

Purpose: The purpose of this study was to compare the intramuscular activation of the scapular stabilizing muscles and the upper trapezius/middle serratus anterior (UT/MSA) ratios during shrug exercise and proprioceptive neuromuscular facilitation (PNF) scapular pattern exercise. Methods: The participants of this study were 13 young adult men who voluntarily consented to participate in this experiment after listening to its purpose and methods. All participants were instructed on maximal voluntary isometric contraction and scapular exercises. The intramuscular activation of the upper trapezius (UT), lower trapezius (LT), middle serratus anterior (MSA), and lower serratus anterior (LSA) muscles while performing scapular exercises in a side-lying position were measured using surface electromyography. To analyze the muscle activation and UT/MSA ratio between the two exercises, a one-way repeated ANOVA was performed. Post-hoc analyses were conducted using Tukey's multiple comparison and analysis. Hamstring flexibility for each group was measured by a passive straight leg raising test. Results: The shrug exercise showed significantly higher UT activation compared to PNF anterior elevation and posterior elevation scapular patterns. The PNF scapular anterior elevation pattern showed significantly higher serratus anterior activation than the shrug exercise. Additionally, the UT/MSA ratios were significantly lower in the PNF scapular anterior elevation pattern than in the two exercises. Conclusion: Although shrug exercise was effective for strengthening UT, the PNF scapular anterior elevation pattern may be effective for strengthening MSA and improving the UT/MSA ratio.
