An Exploratory Study Investigating the Time Duration of Slip-Induced Changes in Gait
… in gait. The required coefficient of friction (RCOF), a parameter highly predictive of risk of slipping, was measured on thirty-one young male adults during level gait on three separate days before slipping, immediately (<10 minutes) after slipping, and either one, two, four, or six weeks later. …

The Effects of Age on Stress and The Biomechanics of Slips and Falls
… step length, required coefficient of friction (RCOF), slip distance, and heel contact velocity. Physiological parameters included: stress and anxiety. Overall, the results indicated that there were differences between older and younger adult's biomechanical parameters of walking, and their …

Effects of Quadriceps Fatigue on the Outcomes of Slips and Falls
… (HCV), required coefficient of friction (RCOF), slip distance II (SDII), peak average knee joint moment during slip recovery (kneemompeak), fall frequency and, a decrease in the transitional acceleration of the whole body COM (TA) in the fatigue session further indicating higher slip …

Assessing the Effects of Exoskeletons on Physical Demands, Trip and Slip Risks, and User Perceptions in Manual Mining Tasks
… (MFC) and required coefficient of friction (RCoF). Rigid BSEs increased right foot MFC and RCoF, whereas the soft BSE largely preserved baseline gait mechanics, with no significant effects on objective slip or trip risk metrics. Overall, we found that the efficacy of ASEs and BSEs are highly …

Evaluation of Gait and Slip Characteristics for Adults with Mental Retardation
… a lower required coefficient of friction (RCOF) and slower heel contact velocity which, alone, would suggest a reduced slip propensity as compared with the healthy group. A greater peak sliding heel velocity and greater slip distance measures, however, indicate greater slip severity for the …

Relationships between Hamstring Activation Rate and Biomechanics of Slip-induced Falls among Young and Older Adults
… of older adults’ slower walking velocity, lower RCOF, shorter slip distance, and slower peak sliding heel velocity, suggested that the recovery phase of the slip-induced fall accidents should be studied further.

Age-Related Ankle Strength Degradation and Effects on Slip-Induced Falls
… results also indicated that older individuals' RCOF was less than their younger counterparts. However, older individuals fell more often than younger individuals. It is concluded that friction demand characteristics may not be a total deterministic factor of fall accidents. Thus, the further …

Toward understanding factors affecting falls among individuals who are obese
… faster walking speed, longer step length, higher RCOF, worse executive function (working memory), and lower BMI. Slower reactive recovery response was also associated with lower BMI. As such, better selective attention and stronger muscle strength exhibited limited benefit in slip recovery among …
