“…Floors, walkways or ground surfaces are a major extrinsic factor for fall accidents, causing over 86% of all fall-related injuries [2]. Occupationally induced localized muscle fatigue (LMF) has been identified as one of the intrinsic factors contributing to slip and fall accidents [3,4,5]. A third of the U.S. workforce exerts considerable strength as part of the demands of their employment and experience consequent fatigue at work [6].…”

Effects of quadriceps fatigue on the biomechanics of gait and slip propensity

This study examines how lower extremity fatigue of the quadriceps alters gait variables related to slip propensity. Sixteen healthy young adults were recruited to walk across vinyl floor surfaces in states of fatigue and no fatigue. Kinematic and kinetic data were collected using a three-dimensional motion analysis system and force plates. The results indicated a significant increase in both the heel contact velocity and required coefficient of friction and a decrease in the transitional acceleration of the whole body center of mass and peak knee joint moment in the fatigue trials. Thus, suggesting that slip propensity could increase with fatigue. Additionally, there was increased knee flexion and reduced ankle dorsiflexion at the heel contact phase of the gait cycle during fatigue trials. These findings provide new insights into the biomechanical relationship between localized muscle fatigue and gait parameters associated with slip propensity. The present study concluded that localized muscle fatigue affects gait parameters and hence can be considered as a potential risk factor for slipinduced falls.

Many causes for falls from ladders in construction are related to the user's activities; however, the extent to which users comply with ladder use best practices is unknown and has not been well quantified before. We developed and tested an audit tool that assesses compliance with best practices guidelines for portable ladder use designed for applications in the construction industry. Implemented on a hand-held computer, the assessment tool consisted of a series of checklists categorized in four groups; ladder condition, setup, moving on a ladder, and completing tasks from a ladder. For these four observational categories, the resulting tool contained 31 and 33 questions for step and extension ladders, respectively. Three individuals trained to use the tool scored a set of photographs and videos depicting 25 ladder conditions, 20 ladder setups, 10 users moving on ladders, and 13 users completing tasks from a ladder for a total of 78 observations. The assessment tool had good agreement across and within raters. For the three raters, agreement ranged from 79% to 97% across the questions. Within one subject, kappa coefficients for the intrarater reliability ranged from 0.67 to 0.91. The tool offers a practical method to quantify best practices associated with ladder use that can ultimately inform targeted intervention efforts. KeywordsLadder; Construction; Falls; Fall Hazard Identification INTRODUCTIONFalls from ladders are a serious and often overlooked cause of falls. In the United States construction industry, falls from ladders are responsible for 16% of all fatal injuries and 24% of non-fatal injuries that involved days away from work (CPWR, 2008). These falls can often disable workers (Smith et al., 2006). Nearly 40% of workers with ladder-related injuries were absent from work for more than a month (Axelsson and Carter, 1995) and half of those injured "experienced continuing, possibly permanent disability." A majority of these ladder injuries involve portable ladders.While many efforts have developed specific design standards (e.g. ANSI.A14) for ladder safety, many of the causes for falls are related to the use of practices (Cohen and Lin, 1991).
