As the elderly population increases, the number of patients with various joint diseases, including degenerative arthritis, is steadily increasing. CPM medical devices are needed to effectively treat degenerative arthritis that is common in the elderly population. Domestic CPM medical devices have limited functions and are highly dependent on imports for expensive imported medical devices. To solve this problem, we designed a ROM measurement function using a current sensor that is not present in existing composite joint CPM medical devices. The algorithm was designed using the fact that the force caused by joint stiffness greatly increases the current flowing through the DC motor. In addition, the need for digital healthcare in the medical field is gradually expanding as the proportion of chronically ill patients increases due to the spread of the non-face-to-face economy due to COVID-19 and the aging population. Therefore, this paper aims to improve the performance of CPM medical devices by allowing real-time confirmation of rehabilitation exercise information and operation range measurement results in accordance with digital healthcare trends through a Bluetooth application developed as an Android studio.

Purpose : The purpose of this study was to investigate the effects of combined cervical stabilization exercise (CSE) and stretching exercise (SE) on office workers with forward head posture (FHP). Methods : A total of 32 office workers with forward head posture were randomly assigned to experimental (n=16) and control (n=16) groups. The experimental group underwent combined CSE and SE, and the control group underwent cervical self-myofascial release and SE. Both groups performed exercises for 40 min per day, thrice per week for a total of 6 weeks. Craniovertebral angle (CVA), respiration, disability, and joint range of motion (ROM) before and 6 weeks after intervention were measured and compared. Results : There was no significant between-group difference in the general characteristics (p>.05). The intra-group comparison showed significant differences in the visual analog scale (VAS) and neck disability index (NDI) of both groups post-intervention (p<.05). CVA and forced expiratory volume in 1 seconds (FEV₁) were significantly improved post-intervention in the experimental group only (p<.05). In the experimental group, all ROM variables were significantly improved post-intervention. In contrast, in the control group, all ROM variables improved significantly post-intervention, except for extension (p<.05). The inter-group comparison showed significant differences in NDI, left lateral flexion, right lateral flexion, and left rotation between the two groups (p<.05). Conclusion : The combination of CSE and SE, which stabilizes the cervical spine, had positive effects on cranial rotation angle, respiration, disability, and joint ROM in office workers with forward head posture. Therefore, the combination of the two exercises may be an effective option to reduce symptoms and prevent postural problems in office workers with FHP.

PURPOSE: The main objective of this study is observing the effects of the functional postural trunk exercise (FPTE) on deep cranio-cervical flexor (CCF) muscle endurance applied on neck pain patients suffering from the acute whiplash-association disorder (WAD). METHODS: The study was tested with 47 patients with neck pain. All patients were equally treated with the ordinary therapy, only experimental group (n=23) was treated with FPTE: assumption of an upright lumbo-pelvic and spinal postural position, adding a neck lengthening manoeuvre in addition. Patients attended physical therapy for 3 times a week, for 4 weeks. Visual analogue scale (VAS) for pain, neck disability index (NDI), range of motion (ROM), were recorded both before and after the intervention. Also muscle activity in the CCF test was employed to analyze the changes between before and after. RESULT: After 4 weeks of training intervention, a remarkable increase in muscle endurance, rotation, extension ROM (p<.05) and decrease in pain and NDI (p<.05) in both groups. Further, the differences between groups were muscle endurance (F=60.350, p<.01), pain, and the left rotation ROM (p<.05). CONCLUSION: From the results, the experimental group had significant the increase in muscle endurance, and the significant decrease in pain. Whilst further research in this category is necessary, these observations suggest that applying exercise in early diagnosis can be of help to treat the neck pain patients suffering from the WAD.

Purpose: This study aims to determine the effect of proprioceptive neuromuscular facilitation (PNF) pectoralis minor stretching and lower trapezius strengthening exercise on posture change, shoulder range of motion (ROM), and pain in rotator cuff repair patients with a rounded shoulder posture (RSP). Methods: Following baseline measurements, the subjects (n = 25) with rotator cuff repair were randomized into two groups: the PNF group (n = 13), which engaged in PNF pectoralis minor stretching and lower trapezius strengthening exercise, and the control group (n = 12), which received traditional physical therapy. Each group participated in the intervention five times per week for two weeks. The RSP values for the postural changes, flexion and abduction ROM, and visual analogue scales (VASs) of both groups were recorded at both pre- and post-intervention. In addition, before and after the intervention, a paired t-test was conducted to compare the within-group changes and an independent t-test to compare the between-group differences. Results: After the two-week intervention, both groups experienced significantly decreased RSP and VAS values (p < 0.05) and a significantly increased ROM (p < 0.05). Meanwhile, the PNF group showed greater improvements in RSP, ROM, and VAS than the control group (p < 0.05). Conclusion: These results suggest that PNF pectoralis minor stretching and lower trapezius strengthening exercise reduce posture and shoulder pain and enhance ROM in rotator cuff repair patients with RSP.

Purpose: This study was to develop and evaluate stability and effects of an early exercise program for patients with open heart surgery. Methods: The subjects of this study were 30 patients who had either a coronary bypass surgery or a valvular heart surgery at a tertiary hospital in Seoul. The data was collected by observation and measurement from October 1, 2004 to November 15, 2004. Results: The early exercise program developed for this study consisted of range of motion exercise and walking. Intensity of walking was 1~3 METs and increased progressively to daily target distance. During exercise, the subjects were monitored heart rate, blood pressure and RPE (Rating of Perceived Exertion). The mean FIM (Functional Independent Measurements) score of subjects was significantly improved after the early exercise program. However, several complaints such as dizziness or pain were also reported. Most complaints were associated with chest tube and RPE. Conclusion: The early exercise program can help to recover patients' physical activities after surgery, and can be applied to most patients. Patients' RPE, dizziness and pain was possible limitations, therefore, active pain control and prevention of accidents for patients would be needed.

Objective: Flexed posture commonly increases with age in older adults and is characterized by kyphosis and forward head posture. Changes in the posture with age affect both balance and mobility. This study was conducted to examine the effects of a cervical stabilization exercise for community-dwelling older adults to improve balance. Design: Two groups pretest-posttest design. Methods: Fifty older adults were randomly assigned into the cervical stabilization exercise group (n=24) and control group (n=25). The cervical stabilization exercise group (n=24) participated in group exercise for 60 minutes twice a week over 4 weeks. Timed up and go test (TUG), four square step test (FSST), functional reach test (FRT), postural sway, cervical range of motion (CROM), proprioception, craniovertebral angle (CVA) were evaluated before and after the intervention. Results: TUG, FSST, FRT, CROM, Proprioception, CVA showed significantly greater improvement, compared with a control group (p<0.05). Conclusions: Findings of this study demonstrate that cervical stabilization exercise can help improve not only neck functional capacities but also balance. Therefore, it may be used as an effective balance exercise program for community-dwelling older adults.
