There is some equipment that helps user to exercise and to walk. But almost all equipments require some physical strength of their muscles. So we developed a system that could assist walking action of the people with lower-limb disability. The system called as walking stand adopted the balancing mechanism which assures the stable walking, and the 4 link-based mechanism that had 2 degrees of freedom on each leg. The walking stand uses four motors and has two sets of the special link-structure to simulate the human walking mechanism. With our system, even serious disabled with lower-limb disability may enjoy walking rehabilitation. And by adjusting the power, it can be used as the walking assistant mechanism instead of conventional wheelchairs. Experiments showed that our walking stand is applicable to the rehabilitation and also to the mobile device in our daily life for those people who do not have enough physical ability to walk by themselves.

Objectives: The purpose of this study was to investigate risk factors for chronic ADL, IADL disability. The study explored clinical and socio-demographic risk factors of functional status decline. Methods: Data from the Survey of Living Condition of Elderly 3-year panel study were analyzed. The study subjects were 5,928 community-dwelling people aged 65 years or older who were no disability in ADL and IADL at baseline. Predisposing factors, pathology, impairment, and functional limitations were regarded as risk factors. Logistic regression analysis was used. Results: During the 3-year study period, 3.9% participants developed chronic ADL disability, 9.4% participants were IADL disabled. After controlling for predisposing factor, the best predictors for ADL disability at 36 months were fall as a pathology factor, cognitive decline, disability judgement, lower limb functional limitation. Comorbidity, fall, cognitive decline, disability judgement, lower limb and upper limb functional limitation were risk factors for IADL disability. Conclusions: Health promotion program focusing elderly is essential to prevent ADL and IADL disability. Mobilizing physical activity should be included in health promotion program for elderly.

The number of reported cases with dual disability is increasing for the past few decades. Currently, dual disability of lower limb amputation and motor weakness after stroke became a strong issue in public concern. The functional levels of patients have shown in the wide range from independent community ambulation to non-ambulation. Thus, it indicates that favorable outcomes for dual disability may depend upon adopted rehabilitative strategies. We present the case of a man with left below-knee amputation and severe right-sided weakness following a huge putaminal hemorrhage. He had suffered from extreme pain and misfit of the prosthetic socket and the complicated residual limb for three years prior to the stroke. Forty days post-stroke, we performed a revision surgery to resolve the complications of bony overgrowth, verrucous hyperplasia, and neuroma and applied an ankle foot orthosis (AFO). Two years post-stroke, he was able to ambulate outside his home and negotiate stairs using a cane. This is the first case with the dual disability of lower limb amputation and contralateral hemiplegia to undergo revision surgery. The results suggest that an early revision surgery and use of an AFO are crucial for achieving a higher level of mobility in such cases.

Objectives: The objective of this study was to identify the differences in obesity rates among people with and without disabilities, and evaluate the relationship between obesity rates and the existence of disabilities or characteristics of disabilities. Methods: Mass screening data from 2008 from the National Disability Registry and National Health Insurance (NHI) are used. For analysis, we classified physical disability into three subtypes: upper limb disability, lower limb disability, and spinal cord injury. For a control group, we extracted people without disabilities by each subtype. To adjust for the participation rate in the NHI mass screening, we calculated and adopted the weight stratified by sex, age, and grade of disability. Differences in obesity rates between people with and without disabilities were examined by a chi-squared test. In addition, the effect of the existence of disabilities and grade of disabilities on obesity was examined by multiple logistic regression analysis. Results: People with disabilities were found to have a higher obesity rate than those without disabilities. The obesity rates were 35.2% and 35.0% (people with disabilities vs. without disabilities) in the upper limb disability, 44.5% and 34.8% in the lower limb disability, 43.4% and 34.6% in the spinal cord injury. The odds for existence of physical disability and grade of disability are higher than the nondisabilities. Conclusions: These results show that people with physical disability have a higher vulnerability to obesity.

Many walking stands, and assisting tools have been developed for the people with low-limb disability to prevent diseases from bedridden state and to help them walk again. But many of those equipments require user to have some physical strength or balancing ability. In our last research, we developed walking assist system for the people with lower-limb disability. With the system, user can be assisted by actuators, and do not have to worry about falling down. The system adapted the unique closed links structure with four servomotors, three PICs as controller, and four limit switches as HMI (human man interface). We confirmed the adaptability of the system by the experiment. In this research, Muscle Stiffness Sensor was tested as the advanced HMI for walking assist system, and confirmed the adaptability by the experiment. As Muscle Stiffness Sensor can attain the muscle activity, user can interface with any device he want to control. Experimental result with Muscle Stiffness sonsor showed that user could easily control the walking assist system as his will, just by changing his muscle strength.

Purpose: The aim of the study was to investigate neck posture, range of motion, muscle endurance and self-report of pain and disability in smartphone users. Methods: Seventy-eight university student volunteers, aged between 18 and 30 years (mean age 23.2), were assessed for: a head-neck posture by measuring cranial vertical angle, neck range of motions using cervical range of motion device, and a deep neck flexor endurance using a stabilizer. Finally, subjects were asked about their neck pain and completed disability questionnaires, ie, Short Form McGill Pain Questionnaire, Neck Disability Index, and World Health Organization Disability Assessment Schedule 2.0. Results: Thirty-eight subjects experienced recurrent neck pain with/without upper limb pain (neck pain group) and 40 reported no current neck pain with/without upper limb pain (no neck pain group). Differences were found between groups on pain and disability questionnaires. Subjects with neck pain had significantly higher disability scores than those of no neck pain group. However, there were no differences observed between groups in a head-neck posture, neck range of motions, and deep neck muscle endurance time. The smartphone usage time was negatively correlated with neck pain intensity and disability score whereas it had positive relationship with flexibility and posture. Conclusion: Group differences were observed as lower capacity not only for neck specific daily activities but for general functioning in daily routine when the neck pain and no neck pain groups were compared. Therefore, functioning in daily activities should be investigated as prevention for further developing neck pain in smartphone users.
