“…Alkjaer [6] found partly unloaded ankle and knee joints due to reduced knee extension and plantar flexion. These findings agree with a significant reduction in lower-limb muscle activity [7]. This effect was stronger if weight-bearing was increased.…”

Despite the common use of jogging strollers, only a few studies cover their influence on running patterns. Kinematic studies have shown differences in the upper body movement, while potential changes in plantar pressure remain unclear. Therefore, 30 healthy sport students were asked to run at a self-selected speed with and without a jogging stroller on a treadmill. Via bilateral insole pressure measurements, the plantar pressure distribution and the stride length were quantified. A significantly decreased pressure for running with a jogging stroller was found in the forefoot, metatarsus, inner edge, outer edge and for the total pressure of the left foot. The right foot showed similar significances for all foot areas except the metatarsus. Stride length was significantly shorter when running with a jogging stroller. As stride length and plantar pressure are known to correlate, the reduced stride length in running with a jogging stroller can partially explain the measured decrease in plantar pressure. Further, the partial weight-bearing, which is needed to keep the jogging stroller in line, can also contribute to the decrease in plantar pressure. Moreover, the unilateral weight-bearing enlarges the base of support and could also be a reason for the decrease in plantar pressure. In conclusion, our results show statistically significant changes in plantar pressure, but these are not of clinical importance as the effect sizes are very low. Therefore, no specific training recommendations for running with a stroller have to be made.

“…It is important to understand the interaction with FWWs so that appropriate modifications can be made using mechatronic components of SWs. Although FWWs are widely used, detailed understanding of their functioning, and limitations of their design, is still lacking because most research has focused on prescriptive suitability and the risks and effects of use on a patient (Alkjaer et al, 2006;van Riel et al, 2014;Suica et al, 2016).…”

Walking is essential to our everyday lives, both socially and in our ability to perform basic everyday tasks. However, a significant number of people suffer from walking difficulties, especially people of older ages. Smart walkers are assistive devices that support independent living by extending the capabilities of four-wheeled walkers. The augmentative nature of this device means that there is a need for compatibility with the user's gait and balancing needs. This aspect has not yet been fully explored as most previous studies have focused upon the technological features of smart walkers. This paper aims to highlight and elaborate upon some of the challenges associated with developing smart walkers from an ergonomics perspective.

Background: Sit-stand workstations are available for office work purposes but there is a dearth of quantitative evidence to state benefits for lower limb outcomes while using them. And there are no guidelines on what constitutes appropriate sit/stand time duration. The primary aim of this study has been to compare muscle activity and perceived discomfort in the lower extremity during various combinations of sit/stand time duration associated with a sit-stand workstation separately and to evaluate the effects of the sit-stand workstation on the lower extremity during the text entry task. Material and Methods: During the 5 days, all participants completed a 2-h text entry task each day for various sit/stand time duration combinations as follows: 5/25 min, 10/20 min, 15/15 min, 20/10 min, 25/5 min. Lower extremity muscular exposure of 12 male and 13 female participants was collected at 8 sites by surface electromyography and body discomfort was calculated by a questionnaire under those 5 conditions. Results: Results have demonstrated that lower extremity muscle activity has been significantly varied among the 5 sit/stand time duration groups. Perceived level of discomfort (PLD) has not differed significantly for 9 out of 10 body parts. Conclusions: The muscle activity of the thigh region was influenced by sit/stand time duration significantly. Ergonomic exposures of lower extremity when using a sitstand workstation were increased, particularly during the long time standing posture. Results indicate that body mass index (BMI) and gender were not significant factors in this study. Combination of sit/stand time duration 25/5 min appears to show positive effects on relief of muscle exposure of back of thigh in the shifts of sitting and standing work position.
