Objective: This study aims to compare the range of motion of the joints by applying the contraction and relaxation techniques used in manual therapy as electrical stimulation treatment. Based on this, we would like to propose the possibility of using motor nerve electrical stimulation therapy for musculoskeletal physical therapy. Design: Single-arm interventional study Methods: Active and passive straight leg raising tests were performed on 20 healthy men and women in their 20s to measure the angle of hip joint flexion. Then, the electrical stimulation time was set to 10 seconds and 5 seconds of rest, and motor nerve electrical stimulation of 1 Hz was applied with the maximum strength that could withstand the hamstring muscles for 10 minutes. After electrical stimulation, straight leg raising tests again to confirm the range of motion of the hip joint flexion. Results: As a result of this study, it was confirmed that the joint range of motion was significantly improved for both active and passive straight leg raising tests after application of motor nerve electrical stimulation(p<.05). Conclusions: With a strong electrical stimulation treatment of 1 Hz, the effect similar to the contraction and relaxation technique used in manual therapy was confirmed through the joint range of motion. In the future, motor nerve electrical stimulation therapy can be used for musculoskeletal physical therapy to provide a new approach for patients with reduced pain and joint range of motion due to muscle tension.

Purpose: The purpose of this study was to confirm the immediate effect of wrist joint mobilization with taping on the range of motion, grip strength, and spasticity. Methods: Thirty stroke patients were randomly divided into two groups: the joint mobilization with taping group (n=15) and a taping group (n=15). For measurement of spasticity and joint range of motion, the modified Tardieu scale, active and passive range of motion of wrist flexion, as well as extension were measured by the Rapael smart glove, and for grip strength measurement, grip dynamometer was performed. Results: The experimental group showed a significant improvement in the range of motion, grip strength, and spasticity after 10 minutes of taping (p<0.05), no significant difference was found in the control group (p>0.05). However, there was no significant difference between the two groups (p>0.05). Conclusion: The study found that wrist joint mobilization with taping has an immediate effect on wrist range of motion, grip strength, and spasticity in stroke patients, whereas it was not effective in the control group with just taping. The long-term change still needs to be evaluated, when taking into consideration of the carryover effect.

The purpose of this study was to investigate the effects of the increasing ankle range motion program on ambulation and balance for the elderly with balance disorder. Eighteen elderly subjects were administered with a timed test twice; approximately 4 weeks apart. The exercise group participated in a fall prevention exercise class at the Y.S. Senior Welfare Center of the Seoul Metropolitan Government. The session consisted of a stationary cycle, static stretching ankle joints, balance boards, and progressive resistive exercises using the Thera-band. The results were as follows: Firstly, the increasing ankle range of motion program was effective on the exercise group. Gait-speed was improved (p<.005). Secondly, balance was significantly improved (p<.000). Thirdly, increasing ankle range of motion program was effective in ankle dorsiflexion which was the major risk factor for falls among the elderly. Differences in gait and balance between the groups were examined using a paired t-test (p<.05). The exercise group demonstrated significantly higher values of gait-speed, ankle range of motion, and balance when compared with the non-exercise group. The results of this study suggest that the increasing ankle range of motion program is an effective intervention for the elderly with balance disorder.

Background: This study was planned to assess and compare the effectiveness of cervical region stabilization exercise and strengthening exercise on pain and range of motion in patient with chronic neck pain. Methods: Fifty-one patient with chronic neck pain were randomly allocated into strengthening and stabilization exercise (SSE) group (n=27) and Strengthening exercise (SE) group (n=24). The program was carried for 12 sessions, 3 days/week in 4weeks. Pain intensity with visual analog scale (VAS), cervical range of motion, deep cervical flexor strengthening were evaluated before and after the intervention. Results: After the program, pain intensity decreased in group SE and SSE were found (p<.05). Range of motion and deep cervical muscle strength increased in group SE and SSE were found(p<.05). The intergroup comparison showed that significant difference in range of motion and deep cervical muscle strength (p<.05). Conclusions: The study suggest that both SSE program and SE program might be a useful treatment for patients with chronic neck pain. However SSE program might be superior in improving cervical range of motion and deep cervical flexor strength compare to SE program.

Background: The purpose of this study was to find out the real truth of the effect of PROM (Passive range of motion) and AAROM (Active assistive range of motion) exercise on increasing the knee flexion. This randomized, controlled trial examined whether or not the incorporation of PROME(passive range of motion exercise) to a postoperative rehabilitation protocol would offer a better clinical outcome after TKA (Total knee arthroplasty) Method: The subject (n=36) measured range of motion (ROM).18 consecutive patients who underwent TKAs at SNUH dept. OS received PROME for knee by a physical therapist during the physiotherapy sessions and not for the other 18 patients who underwent TKAs received No-PROME (AAROME) for knee by herself. Result: There were significant differences in the PROME group, No-PROME group ROM progress width And there were significant differences in the PROME group between No-PROME group ROM improvement width. Conclusion: This study demonstrates that the incorporation of PROME does offer additional clinical benefits to the patients after TKA. Our findings may suggest that encouraging patients to perform PROM exercises would be a better option and that physiotherapy session by a physical therapist holds good even now.

Objective: Patients with stroke generally diminished ankle range of motion, which decreases balance and walking ability. This study aimed to determine the effect of ankle self-mobilization with movement (s-MWM) on ankle dorsiflexion passive range of motion, timed up and go test, and dynamic gait index in patients with chronic stroke. Design: Randomized controlled trial design Methods: Twenty-four post-stroke patients participated in this study. The participants were randomized into the control (n = 12) and self-MWM groups (n = 12). Both groups attended standard rehabilitation therapy for 30 minutes per session. In addition, self-MWM group was performed 3 times per week for 8 weeks. All participants have measured ankle dorsiflexion passive range of motion, timed up and go test, and dynamic gait index in before and after the intervention. Results: After 8 weeks of training, self-MWM group showed greater improvement in ankle dorsiflexion passive range of motion, timed up and go test, and dynamic gait index than in the control group (p<0.05). Further, self-MWM group had significantly improvement in all dependent variables compared to the pre-test (p<0.05). Conclusions: Our investigation demonstrates that self-MWM is beneficial for improving functional ability. Also, self-MWM was superior to control with respect to improving ankle dorsiflexion passive range of motion, timed up and go test, and dynamic gait index.

This paper propose the fast motion estimation algorithm with adaptive search range adjustment using motion activities of temporal and spatial neighbor blocks. The existing fast motion estimation algorithms with adaptive search range adjustment use the maximum motion vector of all blocks in the reference frame. So these algorithms may not control a optimum search range for slow moving block in current frame. The proposed algorithm use the maximum motion vector of neighbor blocks in the reference frame to control a optimum search range for slow moving block. So the proposed algorithm can reduce computation time for motion estimation. The experiment results show that the proposed algorithm can reduce the number of search points about 15% more than Simple Dynamic Search Range(SDSR) algorithm while maintaining almost the same bit-rate and motion estimation error.

The purpose of this study is to define how wrist motion is affected by different postures and supporting devices and to discover functional range of wrist motion for keyboard typing. The range of wrist motion (ROM) needed for fourteen experienced typists to type on a computer keyboard was measured by flexible and biaxial electrogoniometers. The most frequent wrist motion during typing was in extended and ulnarly deviated positions in both wrists. Range of wrist motion was similar in both wrists. The average ROM for keyboard typing with the typists' own posture was about 39 in flexion/extension (FEM) and 29 in radial/ulnar deviation (RUD) in both wrists. The range of wrist motion was significantly reduced to 30 in FEM and 27 in RUD with use of either wrist or forearm supporting devices, which suggests that these devices might help to relieve fatigue, discomfort, or pain during and/or after typing. Results of this study will be of interest to clinicians and helpful to those who are professionally or non-professionally involved in typing.

Objectives Through this study, we investigated the effects of Korean medicine treatments on range of motion recovery and pain reduction in patients with Frozen shoulder. Methods In this study, the medical records of 26 patients diagnosed with frozen shoulder were retrospectively observed and analyzed through the IBM SPSS Statistics 25 program. We used range of motion to observe the patient's motion recovery and numeric rating scale to evaluate pain reduction. Results The shoulder range of motion increased statistically significantly from 160.0 (123.5~170.0) to 170.0 (160.0~180.0) (flexion), 115.0 (90.0~135.0) to 167.5 (130.0~178.8) (abduction), 40.8±22.1 to 58.3±16.0 (external rotation) (p<0.001). The average of numeric rating scale reduced statistically significantly from 6.7±2.0 to 3.2±1.4 (p<0.001). Depending on the period, the range of motion increased statistically significantly when visited within 3 months, also the pain score decreased 7.0 (5.4~8.0) to 3.0 (1.8~3.6) statistically significantly when visited within 3 months. In the treatment intervention, the increase in the range of motion and the decrease in pain were statistically significant, especially when the bee venom acupuncture and chuna manaul therapy were used together. Conclusions Korean medicine treatments was effective in improving the range of motion and reducing pain in frozen shoulders. In particular, when treated within 3 months of onset and when bee venom acupuncture and chuna manual therapy were used together, it was effective in recovering the range of motion and reducing pain.

The purpose of this research is to measure range of virtual hip joint and lower limb joints motion such as the hip, knee and ankle joints for 47 young male students. The results of ANOVA revealed that anthropometric dimensions including weight and stature did not show any significant effects on the range of virtual hip joint and lower limb joints motion and the range of motion with two degrees of freedom at the shoulder, virtual hip and hip joints. Anthropometric dimensions such as age, weight, statuire, arm length, shoulder height and leg length were found to be lowly correlated with the range of virtual hip joint and lower limb joints motion. It is expected that the data on the range of joint motion suggested in this study can be used as a valuable input data when designing workplace, predicting human posture and reach volume, etc.
