This study compared how falls can be reduced in disabled elderly people by using the Otago exercise program and ascertained the program's effects on physical function and psychological recovery. The subjects were 30 people, and were assigned to two groups. The experimental group had 17 people, and the other was the control group that had 13 people. The experimental group attended the 50-minute program twice a week for 12 weeks. The outcome measures for lower extremity muscle strength, postural balance, flexibility, and self-efficacy were tested at the pre-test and post-test phases. In the analysis, general characteristics were analyzed by descriptive statistics. Physical function and self-efficacy were analyzed by independent T-test between the two groups, and correspondence T-tests were used within the two groups. The result of this study demonstrated that the experimental group showed significant increases in lower extremity muscle strength, static balance, flexibility and dynamic balance, and self-efficacy showed a small increase in the experimental group. But the control group showed significant decreases in static balance, flexibility and fall efficacy. The control group also showed decreases in lower extremity strength and dynamic balance. So the results of this study proved that the Otago exercise program brought about positive changes to improve physical function and psychological function to help prevent disabled elderly people from falling.

This paper describes a novel type of a walking rehabilitation robot that applies robot technologies to crutches used by patients with walking difficulties in the lower body. The primary features of the developed robot are divided into three parts. First, the developed robot is worn on the patient's chest, as opposed to the conventional elbow crutch that is attached to the forearm; hence, it can effectively disperse the patient's weight throughout the width of the chest, and eliminate the concentrated load at the elbow. Furthermore, it allows free arm motion during walking. Second, the developed robot can recognize the walking intention of the patient from the magnitude and direction of the ground reactive forces. This is done using three-axis force sensors attached to the feet of the robot. Third, the robot can perform a stair walking function, which can change vertical movement trajectories in order to step up and down a single stair according to the floor height. Consequently, we experimentally showed that the developed robot can effectively perform walking rehabilitation assistance by perceiving the walking intention of the patient. Moreover we quantitatively verified muscle power assistance by measuring the electromyography (EMG) signals of the muscles of the lower limb.

The purpose of the present study was to determine the effect of a 4 week course of Cox distraction manipulation (CDM) combined with therapeutic modalities on the treatment of patients with L4-5 herniated nucleus pulposus (HNP). A total of 15 patients with L4-5 HNP (mean age, 37.76 years; age range 20-50years) participated in the study. A 4 week course of CDM combined with therapeutic modalities was delivered to the patients for 6 days per week for the first two weeks, and three times per week for two additional weeks. The entire treatment consisted of 18 visits over 4 week period. Comparisons of changes in the muscle strengthening (MS), straight leg raise (SLR), and oswestry disability index (ODI) at pre-intervention, after two weeks treatment sessions, and at discharge (after 18 treatment sessions) were analyzed. Comparisons of changes in the disc herniation index (DHI) at pre-intervention and at discharge were analyzed using the paired t-test. There were significant improvements in the outcome measures of MS Ibs, SLR test, and ODI score after 2 weeks and 4 weeks sessions of CDM combined with therapeutic modalities as compared with the pre-intervention. However, no significant different pre-test and post-test DHI. CDM combined with therapeutic modalities appears to be a safe and efficacious, noninvasive treatment modality for patients with L4-5 HNP.

The purpose of the present study was to determine the effect of 4 weeks course of motorized spinal decompression delivered via SpineMT(mobilization & traction) combined with therapeutic modalities on the treatment of patients with lumbar radiculopathy(LRP). A total of 15 patients with LRP (mean age, 36.63 years; age range 20-50years) participated in this study. 4 weeks course of spinal decompression delivered via SpineMT combined with therapeutic modalities was delivered to the patients for 6 days per week for the first two weeks, and four times per week for two additional weeks. The entire treatment consisted of 20 visits over 4 week period. Comparisons of changes in the muscle strengthening (MS), straight leg raise (SLR), and Oswestry disability index (ODI) at pre-intervention, after 10 treatment sessions, and at discharge (after 20 treatment sessions) were analyzed. There were significant improvements in the outcome measures of MS test, SLR test, and ODI score after 10 and 20 sessions of spinal decompression treatment combined with therapeutic modalities as compared with the pre-intervention(p<0.05). Spinal decompression treatment combined with therapeutic modalities appears to be a safe and efficacious, noninvasive treatment modality for patients with LRP.

When the eldery with limited mobility and disabled use a wheelchairs to move, it can cause decreased exercise ability like decline muscular strength in upper limb and lower extremities. The disabled people suffers with spinal cord injuries or post stroke hemiplegia are easily exposed to secondary problems due to limited mobility. In this paper, We designed intelligent wheelchair robot system for upper limb and lower extremities exercise/rehabilitation considering the characteristics of these severely disabled person. The system consists of an electric wheelchair, biometrics module for Identification characteristics of users, upper limb and lower extremities rehabilitation. In this paper, describes the design and configurations and of developed robot. Also, In order to verify the system function, conduct performance evaluation targeting non-disabled about risk context analysis with biomedical signal change and upper limb and lower extremities rehabilitation over wheelchair robot move. Consequently, it indicate sufficient tracking performance for rehabilitation as at about 86.7% average accuracy for risk context analysis and upper limb angle of 2.5 and lower extremities angle of 2.3 degrees maximum error range of joint angle.

포근한 날씨가 이어지면서 몸과 마음을 펼치고자 주말 등산에 오르는 사람들이 많다. 초보자들은 무리한 산행을 하지 않도록 한다. 평소 지속적으로 운동을 즐겨하던 사람들도 갑작스런 근육 사용의 증가로 쉽게 지칠 수 있다. 초보자들은 다리가 후들거리는 상태가 되면 가급적 쉬었다 이동하거나 더 이상 을 타지 않고 내려오는 것이 좋다. 근력이 떨어졌을 때 무릎이나 발목이 다치기 쉽기 때문이다. 특히 릎 연골이나 골판은 한 번 손상을 받으면 재생이 되지 않는다. 그러므로 다치지 않는 것이 최상이다. 등산 시 꼭 숙지해야 할 안전사고에 대처하는 요령과 응급처치에 대해 알아본다.

The purpose of this study was to examine the effect of kinesio taping on muscle strength and changes of muscle fatigue and damage. 10 male subjects participated in 1-RM and isometric cybex muscle strength tests with and without taping application. Muscle strength (bench press, leg press) and extension (knee, shoulder) strength were significantly increased after taping, but there was no significant difference in flexion (knee, shoulder) strength. The concentration of fatigue factors (ammonia, phosphorous), muscle damage index substances (CK, LDH), IGF-I and creatinine were reduced after taping, but there were no significant differences.
