Efficacy of three interventions at mitigating the adverse effects of muscle fatigue on postural control

Abstract

We examined the effects of three control strategies on postural control in the presence of muscle fatigue induced by a simulated occupational task. The findings can facilitate the development of future strategies or practical interventions to reduce falling risk and prevent falls.

The Impact of a Rigorous Multiple Work Shift Schedule and Day Versus Night Shift Work on Reaction Time and Balance Performance in Female Nurses

“…33 Such findings may demonstrate that (1) postural stability may not only be compromised by general fatigue, but that wholebody postural consequences may also result from localized neuromuscular stress/fatigue, 32 (2) fatigue may be implied as a contributor to an increased risk of falling, 32,34 and (3) that certain interventions may be effective in mitigating fatigue-related impairments in balance and falls risk. 31 Although Sobeih et al 35 examined firefighters, their findings support the present findings in which they found that postural stability decreased across a long work shift, which prompted the conclusion that this may contribute to the high falls prevalence observed in firefighters. This model may also be applicable to nurses, as they also have a very high prevalence of falls, work very long hours, and demonstrate poorer balance performance than either construction workers or firefighters.…”

Musculoskeletal and neurological injuries associated with work organization among immigrant latino women manual workers in North Carolina

“…Work demands, particularly in terms of posture and psychological demand, for the types of manual work held by the participants in this research need to be examined in light of current ergonomic standards. Ergonomic changes can reduce the risk of some musculoskeletal and neurological injuries [Lin et al, 2012;Kim and Nussbaum, 2013]. Increased frequency of breaks can reduce work injuries, sometimes without impeding productivity [Dababneh et al, 2001;Tucker et al, 2003].…”

Effects of different weights and lifting postures on balance control following repetitive lifting tasks in construction workers

“…However, akin to other proprioception studies that examined repetitive lifting tasks (Sparto et al, 1997a;Lin et al, 2012) the current study has some limitations. First, the sample size was relatively small albeit, significant and second, the study was conducted on student participants in a laboratory setting.…”
