“…[22] You also may notice that your hamstrings feel tight after a long day of sitting at your desk; this can cause them to pull on your lower back and create back pain. Along with all the focus on back pain, it has been ignored that prolonged sitting has proved to be one of the prime causes of "The dead butt syndrome" or so called in the textbooks "Lower cross syndrome" [23] .…”

This study has been undertaken to assess the back-leg muscle strength in administrative job workers and then compare the readings/values of physically active population with physically inactive population of administrative staff, in Dr. Vithalrao Vikhe Patil Memorial hospital and medical college. The study used “IPAQ-sf Questionnaire” to estimate the level of physical activity and amount of sitting behaviour in hours throughout the day of the week and “Isometric back-leg-chest dynamometer” to assess the back and leg muscle strength of the 74 administrative staff, male (68.9%) and female (31.1%) involved in the study. The findings of the study indicated significant differences in the back-leg muscle strengths of both physically active and inactive population in both the male and female groups. On comparing the physically active population with physically inactive, in the male group inactive the results showed a significant difference in back muscle strength (0.0224) and leg muscle strength (0.0289) and in female group the leg strength (0.0200) showed a higher significant difference than back strength (0.0003). This workplace delivered that the more the physical active of an individual irrespective of the age and genders the better the back-leg muscle strength and the more number of years a person worked in a sitting-environment weaker the back-leg muscle strength. Keywords: Physical activity, Physical inactivity, Dynamometry, Isometric Dynamometer, BLC dynamometer, Administrative workers.

“…In [10], CoP measurements obtained from a MatScan ® PSM and AMTI ® AccuSway force platform were compared in single-legged balance trials with healthy volunteers. In [7], a Tekscan ® HR Mat and an AMTI ® force plate were used to assess standing balance in typical children and in children with cerebral palsy. In general, the studies found moderate-to-strong agreement between the instruments for some CoP parameters.…”

Center-of-pressure (CoP) displacements play a key role in studies assessing postural stability. The accepted instrument to measure CoP trajectories is the force platform, but pressure-sensitive mats (PSMs) are an alternative composed of a matrix of sensitive cells. A typical cell comprises two electrodes with piezoresistive material in between, while a force platform has a force sensor at each of its corners. In this paper, we compare a homemade Velostat-based PSM and an affordable commercial mat with a commercial force platform in a test series with 42 healthy volunteers in single-legged trials (29 males, 13 females; height 1.74 (0.09) m, weight 74.3 (16.34) kg, age 31.21 (12.66) years). The aim of the research was to perform a preliminary study of the performance of our prototype to measure CoP, and more specifically, the standard deviation of the CoP path on both axes, the medial–lateral and anterior–posterior. We could thus discover several improvements for future clinical applications. The intraclass correlation coefficient (ICC) for agreement in the base experiment showed a moderate value for the prototype (0.38 to 0.63) and lower values for the commercial mat (0.11 to 0.12). However, we identified several factors that were relevant to improve ICC and reduce error by considering several processing options: (i) the known crosstalk problem between cells that appears in this kind of mats must be eliminated; (ii) the response time of the sensor has to be taken into account; and (iii) increasing the mat resolution also improves agreement. Therefore, as future work, we plan to test the improved version of the prototype in a clinical environment.

“…Balance function is also compromised in children with SEN, in terms of static and dynamic balance. Children with more severe cerebral palsy (higher gross motor function classification system level) recorded a greater magnitude of postural sway during a static balance measure than children with normal development, 10 as well as dynamic balance function measured with the Timed Up and Go (TUG) test. 11 Children with Down syndrome tended to spend more time to execute in functional balance tasks, such as performing a standing reach 12 and the TUG test.…”

Introduction Vision is a critical factor for children′s development. However, prevalence of visual impairment (VI) is high in students with special educational needs (SEN). Other than vision disability, this group of students is prone to having functional deficits. It is unclear whether visual problems relate to these compromised functional deficits. This study aimed to assess the impact of vision on visual processing functions and balance performance in SEN students through a community service in special schools. Methods A total of 104 (age 14.3 ± 4.3 years, 43 girls) SEN students in Taiwan were assessed, who were classified as having normal vision (NV) or vision impairment (VI). Visual acuity (distance and near) and contrast sensitivity (CS) were measured as the visual outcomes. Visual processing function assessment included orientation recognition (mailbox game, MB) and facial expression recognition [Heidi expression test, in terms of card matching] (HC), and examiner′s facial expression matching (HF)]. Dynamic balance was assessed with Timed Up and Go (TUG) test, while static standing balance was assessed using a force plate to measure the postural sway in double-legged feet-together and tandem stance with eyes open and closed conditions. Static balance was presented in terms of the change in the centre of pressure in maximal medial-lateral (ML) and antero-posterior (AP) sways, sway variability (V), and sway path length (L). Results Although visual acuity was significantly worse in VI than NV (p < 0.001), CS was similar in the two groups (p = 0.08). MB, HC, and HF also did not differ significantly between groups (p > 0.05). NV performed better in the TUG than VI (p = 0.03). There was a significant interaction between eye condition and the vision group (p < 0.05) for static balance. Pairwise comparisons showed that NV swayed significantly less in ML than VI under tandem stance-open eye condition (p = 0.04), but significantly more in closed eye condition (p = 0.03). Conversely, VI had less V and shorter L than NV under tandem stance-close eye condition (p = 0.03). Conclusion This study is the first to our knowledge to examine the effect of vision on visual processing functions and balance performance in SEN students. Vision did not appear to be the major reason for impairment in visual processing. However, vision plays an important role in maintaining dynamic and static balance in SEN students.
