Relationships between Hamstring Activation Rate and Biomechanics of Slip-induced Falls among Young and Older Adults
… particularly for older adults. Kinematics (heel contact velocity, walking velocity, slip distance, and step length), kinetics (friction demand), and electromyography (EMG) while walking over a slippery surface were collected and examined in the study. Normalized EMG data were examined in …

The Effect of Mental Fatigue on Risk of Falling
… from the required coefficient of friction, heel contact velocity, and heel contact angle. Risk of tripping was inferred from minimum toe clearance and obstacle clearance. The results showed no increase in slip or trip risk. Rest breaks appeared to decrease levels of self-reported mental …

The Effects of Age on Stress and The Biomechanics of Slips and Falls
… 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 physiological stress and …

Effects of Age on Gait Parameters and Muscle Activity During Adjustment, and the Relationship of Fear of Falling
… gait characteristics (friction requirement, heel contact velocity, and step length) and muscle activity characteristics (Integrated EMG). First, a baseline measure was done to study normal gait prior to any exposure to slipping. A second measure was done following a slip from a contaminated …

Evaluation of Gait and Slip Characteristics for Adults with Mental Retardation
… step lengths, and greater knee flexion at heel contact suggesting that their gait patterns share more similarities with the elderly than with healthy adults of an equivalent age. Unexpectedly, the MR group demonstrated a lower required coefficient of friction (RCOF) and slower heel contact …

Effects of Quadriceps Fatigue on the Outcomes of Slips and Falls
… results indicated a substantial increase in the heel contact velocity (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 …

The Effects of Transitioning Between Different Floor Surfaces on Gait Characteristics of the Elderly
… of the whole body center-of-mass (COM), heel velocity at heel contact, perception of slipping/tripping, and toe clearance. It was hypothesized that older participant's gait parameters would be different from their younger counterparts. Also, the older participant's gait adaptation would …
