Development of a Caterpillar-Type Walker for the Elderly People

A walker assists elderly people with age-related reduced walking ability and helps to improve stability and balance ability. However, if the general-type walker (GTW) is used on an uneven, obstacle, or sloped terrain, it may cause excessive muscle use and falls. Therefore, in this study, we developed a caterpillar-type walker (CTW) that elderly people can safely use in various terrains. Twelve elderly who were able to walk normally participated in the study. The activity of upper and lower extremity muscles, the number of obstacles overcome, and walking speed was compared and analyzed when using two types of walkers in uneven terrain, obstacle terrain, and sloped terrain. In addition, satisfaction with the use of these walkers was evaluated. When CTW was used, the activity of the muscles of the upper and lower extremities was significantly reduced compared to the use of GTW on all terrains. The walker developed in this study overcame obstacles of all heights, but the GTW failed to overcome obstacles starting from the 2 cm section. In terms of walking speed, when the CTW was used, the walking speed was higher than that of the GTW in uneven terrain and obstacle terrain. In satisfaction, there were significant differences in safety, durability, simplicity of use, comfort, and effectiveness. Through these results, it was confirmed that the CTW can efficiently and safely assist the elderly in walking on uneven terrain, obstacle terrain, and inclined terrain.

The effects of Kinesio taping-combined exercise on the balance and gait ability of hemiplegic patients

Purpose: This study aims to investigate the effect of the Kinesio taping method on the balance ability and gait ability of hemiplegic stroke patients by applying it to the lower extremities of the ankle on the affected side, addressing instability and asymmetry by improving the stability of the muscles and ankle joint. Methods: This study confirmed the general characteristics of hemiplegic patients diagnosed with stroke. Kinesio taping was applied to the lower extremities of 15 subjects in the experimental group, and they performed mat and treadmill exercises. In addition, basic mat and treadmill exercises were performed by the 15 subjects in the control group. The exercise regimens were performed 18 times: three times a week for six weeks. Results: In the paired-sample T-test used for within-group comparison of BBS, TUG and stance time on nonparetic side value, there was a significant difference between pre- and post-test for experimental group. However, in the control group, there was a statistically significant difference only in TUG. In the inter-group comparison, the experimental group showed a statistically significant improvement in BBS, TUG and stance time on nonparetic side value compared to the control group. Conclusion: The experiment’s results demonstrate that the application of Kinesio taping-combined exercise provides stability of the muscles and ankle joints of the lower extremities during walking by improving balance ability, and improves overall gait stability by increasing the stance phase time of the affected side in hemiplegic stroke patients.

RELATIONS OF MOTOR ABILITY OF BALANCE AND SUCCESS OF PERFORMANCE OF GYMNASTICS ELEMENTS ON THE FLOOR EXERCISE

The purpose of this study is to investigate the relationship between motor ability for balance and the performance of selected gymnastic elements on the floor in students aged 7-8 years, to provide an overview of the current motor status of the respondents at this age, and to develop suggestions for possible changes in the curriculum at this age, and to develop suggestions for supplementing training methodology. Training of selected gymnastics elements was conducted on a sample of 42 subjects who had no previous experience in performing gymnastics elements during regular physical education classes, and the predictor variable was tested using four tests assessing motor balance ability. The tests assessing motor balance ability showed a statistically significant predictive value for the performance of all three gymnastics exercises. It is noticeable that the value of the prediction model increased the more complex an item was derived, indicating the complexity of the motor balance space and the high and stable level of the same in the subjects at the time of testing. Regarding the tests used, it can be noted that the test FLAM was significantly involved in the prediction of performance success in all three gymnastic elements, while the other two tests showed their predictive value in the execution of the hand stand. On the other hand, the study shows that the gymnastic elements used should be used in physical education classes to contribute to the promotion and development of all motor skills of students and as part of the preparation for the execution of more complex elements on the floor and apparatus in higher grades.

Static and Dynamic Plantar Pressure and Normalized Plantar Pressure Characteristics among Children, Adults, and the Elderly

Background: A better understanding of plantar pressure while standing and walking would help in improving balance and gait performance across different age ranges. Objective: To clarify the differences of plantar pressure while standing and walking among children, adults, and the elderly. Materials and Methods: Fifty-three participants including eleven aged 3 to 8 years, thirty aged 20 to 40 years, and twelve aged 60 to 90 years were included in the present study. Plantar pressure and related parameters while quiet standing and walking with self-selected speed were assessed. Results: In static plantar pressure, no significant differences were observed of mean different pressure and mean different contact area between dominant and non-dominant limbs among the three groups, while center of pressure (COP) displacement was shown as significantly greater between children and adults (p<0.05). For dynamic plantar pressure, no significant differences in COP velocity were found among the three groups. The elderly showed significant lower normalized maximum plantar pressure in areas of the second and third metatarsal, and internal heel compared with the young adults (p<0.05). Additionally, normalized maximum plantar pressures among children seemed to differ from adults. Conclusion: Plantar pressure characteristics could indicate that children develop gait ability in braking and propulsion phases with greater heel and toe function, while the ability of braking and propulsion declined with aging. These could reflect balance ability while standing or walking. Keywords: Foot pressure; Children; Elderly; Normalization

Association between Ambient Fine Particulate Matter and Physical Functioning in Middle-aged and Older Chinese Adults: A Nationwide Longitudinal Study

Background Exposure to air pollution is associated with several chronic diseases and subclinical processes that could subsequently contribute to physical disability. However, whether and to what extent air pollution exposure is associated with objective measures of physical functioning remains understudied. Methods We used longitudinal data from the China Health and Retirement Longitudinal Study (CHARLS) and included 10,823 participants who were surveyed at least twice. Annual average exposure to fine particulate matter (PM2.5) was assessed using a state-of-the-art estimator. Physical functioning was assessed with four objective tests covering hand-grip strength, balance, repeated chair stands, and gait speed. Mixed-effects models with participants as a random term were used to estimate associations with multiple adjustments. Results We found a significant and robust association between exposure to increased PM2.5 and the reduction in hand-grip strength and balance ability. Each 10-μg/m 3 increase in annual averaged concentrations of PM2.5 was associated with a 220-g (95% confidence interval [CI]: 127, 312 g) reduction in hand-grip strength per 60 kg of body weight and a 5% risk (95% CI: 2, 7) of reduced balance ability. The estimated effect of each 10-μg/m 3 increase in PM2.5 on hand-grip strength and balance ability was equivalent to the effect of aging [1.12 (95% CI: 0.76, 1.48) and 0.98 (95% CI: 0.50, 1.50) years, respectively]. Conclusions PM2.5 may be differentially associated with various dimensions of physical functioning. Improving air quality can prevent physical disability.
