“…Although we did not observe a statistically significant difference in our study, we found that gait variables were most efficient when the WAV was loaded with a weight of 5% compared to when no weight was added (0%). This shows that an appropriate weight in the WAV has a positive effect on gait by reducing the limitations accompanying physical activity (Shin et al, 2015). Specifically, using an appropriate weight positively lowers the center of mass of the WAV, thereby enhancing trunk stability, reducing tremor of the WAV during movement, and facilitating efficient, stable gait.…”

“…The excessive force required when carrying too much weight increases physical burden and center of mass and trunk movements, which in turn elevates the risk of gait impairment due to reduced ability to maintain balance. Thus, through the contribution of the WAV instability, the risk of overturning increases, which presents considerable danger to elderly individuals during walking (Shin et al, 2015). For this reason, the carrying weight should be considered when using WAVs (Park and Cho, 2008).…”

“…In addition, studies have investigated the detection of dangerous situations with WAVs (Lee et al, 2013), and to compare gait stability between individuals using a WAV and a stroller as a walking aid (Park et al, 2009). The gait pattern according to position and weight when using a walker (Shin et al, 2015) and with an external load applied (Roh and Shin, 2015) have already been analyzed. However, research on walking aids and weight loading has been limited.…”

PURPOSE: This study was conducted to analyze the effects of carrying weight on the gait of elderly women using a walking-assistant vehicle (WAV) as the weight increased. METHODS: A total of 30 elderly women living in the local community were included as subjects and instructed to walk 50 m using a WAV loaded with sandbags corresponding to 0%, 5%, 10%, or 15% of their mean weight. The subjects' gait was analyzed using a gait analyzer to measure stride length, step length, step width, and gait time. RESULTS: Stride and step lengths were longest when carrying 5% of their weight and shortest when carrying 15% of their mean body weight. Step width and gait time were lowest when carrying weights corresponding to 5% and highest for 15% of their mean body weight. When observing gait with a WAV, the gait time was greatly affected by weights, with carrying weight equivalent to 5% of the body

Effect of upper extremity load on pelvic movements during wheeled upright walker use

et al. 2022

This study aimed to elucidate the effects of upper extremity loading on pelvic movements during wheeled upright walker use. [Participants and Methods] Thirteen healthy male adults participated in this intervention study. Participants walked under five conditions with targeted loads on their upper extremities of 0%, 10%, 20%, 30%, and 40% of their body weights using a wheeled upright walker with armrests. Measured items included gait velocity and stride length; the angle of the maximum trunk anterior tilt; the range of motion of the trunk and pelvis in the movements of obliquity, tilt, and rotation; and the amplitude of the center of mass in the vertical and lateral directions captured and calculated using a three-dimensional motion analysis system. [Results] Increasing the load on the upper extremities did not shorten the stride or restrict pelvic movement during gait using upright walker use. The range of pelvic rotation with walker use increased versus that of the standard gait. [Conclusion] The pelvis showed quantitative movements during gait using the wheeled upright walker with armrests. These results could be helpful in the development of robotic assistive devices.

“…Depending on the damage level, it is possible to recommend the use of walking sticks, walkers, wheel walkers or, in extreme cases, wheelchairs. Walkers are used to help balance and totally or partially reduce the weight support of the lower limbs (12)(13) . In addition to common walkers, locomotion trainings based on the partial weight support provide positive results in the static and dynamic balance and help performing the functional gait (12) .…”

Objective: Develop and evaluate a low-cost walker with trunk support for senior citizens. Method: Two-stage descriptive study: development of a walker with trunk support and evaluation with fourth age senior citizens. Results: Twenty-three fourth age senior citizens were selected. The evaluated criteria were the immediate influence of the walker on the static stabilometry with baropodometer and the evaluation of gait with accelerometers monitoring time and amplitude of the hip movement. There was a significant decrease in the body oscillation of senior citizens with the use of the developed walker, and there were changes in the joint amplitudes of the hip, but they were not significant. Conclusion: Using low-cost materials, it was possible to develop and equipment that met resistance and effectiveness requirements. The walker interfered in the balance of the senior citizens, reducing significantly the static body oscillation.

This plot is growing and, according to demographic projections, they will be 30% of the Brazilian population in 2050 (2) . In spite of this growth deriving from the improvement of basic life conditions, functionality cannot follow the passing of time (3)(4) . Therefore, senior citizens are a heterogeneous group as for the independence in completing activities of interest and in the quality of life (2,5) . Among the possible difficulties related to the age increase, there are balance and gait alterations, known as Postural Instability. With the decline of the sensorial capacities and the decrease of biomechanical skills, senior citizens tend to present unbalances and difficulties to maintain orthostatism and, consequently, an independent gait (6) . The most dangerous consequence of these alterations is falling, which may cause fractures and immobilization (4,7) . In these cases, there may be a decrease in the bone mass, reduction of the blood circulation, alterations in the respiratory function, appearance of pressure ulcers, urinary incontinence and intestinal constipation (8) . In addition, falls are the main mortality and morbidity cause among older senior citizens (9) . The occurrence of falling episodes increases with the age, since around 30% of the individuals aged more than 65 falls at least once a year; above 74, this index increases to 35% and after 85 years old, it goes up to 51% (10) . With the intent to stimulate mobility, independence and functionality in senior citizens, it is possible to introduce gait or locomotion helping devices in their routine (11) . Depending on the damage level, it is possible to recommend the ...
