“…This result does not seem to fit the real situation considering that walking upstairs should be more stable than walking downstairs. Walking downstairs is riskier than walking upstairs because of the acceleration added by gravity [ 24 ]. A past study by Chang Gung Medical Foundation also found that 10% of falling cases in the elderly in Taiwan were caused by walking upstairs and walking downstairs with more cases in walking downstairs [ 25 ].…”

Evaluation of human postural stability is important to prevent falls. Recent studies have been carried out to develop postural stability evaluation in an attempt to fall prevention. The postural stability index (PSI) was proposed as a measure to evaluate the stability of human postures in performing daily activities. The objective of this study was to use the PSI in developing the stability scales for human daily activities. The current study used two open datasets collected from mobile devices. In addition, we also conducted three experiments to evaluate the effect of age, velocity, step counts, and devices on PSI values. The collected datasets were preprocessed using the ensemble empirical mode decomposition (EEMD), then the complexity index from each intrinsic mode function (IMF) was calculated using the multiscale entropy (MSE). From the evaluation, it can be concluded that the PSI can be applied to do daily monitoring of postural stability for both young and older adults, and the PSI is not affected by age. The revised stability scales developed in this current study can give better suggestions to users than the original one.

“…It can be assumed that with the lack of integration between the various mechanisms responsible for maintaining the body balance, people with ID compensate their dysfunction by lowering the COG. When adolescents with ID had been analysed during stair climbing, the lowering of the COG as a manner to increase the perception of a safety zone was indicated (Shieh et al 2016). This can result in fixation of the flexion in the hip joints and in destabilisation of muscle tone within the lower leg and ankle joints, which reduces the functional stabilisation of the lower limbs and can contribute to increased sway in the AP direction.…”

Background Children and adolescents with intellectual disabilities (IDs) are an identified group with postural disturbances resulting from a lack of integration among the visual, vestibular and proprioceptive systems. The insufficient level of maturity of the sensory systems is at least partly responsible for disturbances in maintaining body balance. More sway can increase the risk of falls and body injuries. The aims of the study were (1) to compare the ability to maintain the body balance of children and youth with a varying degree of ID, both with the eyes open and closed, and (2) to determine to what extent factors such as sex, level of ID, visual stimulus and body height independently affect the ability to maintain body balance in children and adolescents with ID. Method The study involved 131 people aged 13–21 years (65 girls and 66 boys). The participants were classified as (1) with mild disability (42 girls and 47 boys) and (2) with moderate disability (23 girls and 19 boys), based on IQ test results. Sway measures were collected with the Zebris platform, with the eyes open and closed. Sway path, sway path in anterio‐posterior and medio‐lateral directions and sway area were analysed. Results Boys with moderate ID were characterised by a significantly more sway indicating their worse postural balance ability than boys with mild ID, both in the trials with open eyes and closed ones. The type of test (eyes open/eyes closed) to a small extent had influenced the body balance of the examined children with ID. Results of analyses of covariance had showed that all analysed factors (sex, level of ID, type of the test performance and body height), irrespectively from direction of sway (sway path in anterio‐posterior and medio‐lateral directions), worked independently influencing body balance. Conclusions It could be assumed that lower height, moderate disability and male sex are factors significantly reducing ability of maintenance of balance of children and youth with ID.

“…The first limitation is the relatively small number of participants involved in the programs and the consequent difficulty to determine the strength of the present findings and to shed some light on the performance differences across participants. New studies would need to extend the assessment, which should also include follow-up data ( 31 , 40 ). The second limitation concerns the lack of any specific data regarding (a) the possible benefits of the participants’ response performance (exercise) and (b) the supposed enjoyment of such performance ( 15 ).…”

BackgroundPeople with severe/profound multiple (e.g., intellectual, motor, or sensory–motor) disabilities are frequently restricted to a situation of inactivity and dependence, which may be modified by promoting functional activity engagement through assistive technology.MethodsThis study assessed the possibility of promoting functional activity engagement via microswitch-aided programs with nine participants with multiple disabilities between 10 and 29 years of age. Functional activity consisted of constructive interaction with the immediate environment (e.g., reaching/touching or putting away objects) through the use of response schemes considered practical and beneficial for the participants’ physical exercise and general condition. Microswitch-aided programs were used to monitor the participants’ responses and to automatically provide stimulation opportunities contingent on those responses.ResultsAll participants had a large/significant increase in their activity engagement (i.e., response frequencies) during the microswitch-aided programs, when compared to the baseline periods. These data, which are in line with previous findings in the area, indicate that the programs targeted activity and responses suitable for the participants and ensured contingent stimulation effective to motivate them.ConclusionPeople with severe/profound multiple disabilities can engage in functional activity with the help of microswitch-aided programs.
