A Modeling Investigation of Obesity and Balance Recovery
… loss and strength training to be beneficial to balance, but knowing which is more beneficial will allow researchers to design interventions to maximize the benefits in terms of balance and reducing risk of falls. Therefore, the purpose of the first study was to evaluate the effects of weight …

Visual Contributions to the Vestibulo-Ocular Reflex during Balance Recovery Tasks
… method was used to assess the role of vision in balance reactions. Methods: Experiment 1 : Ten Young subjects were fitted with an eye tracker linked to an EM kinematic recording system. This allowed for the recording of head, trunk and eye kinematics during the performance of gaze stabilization …

The Effects of Obesity and Age on Balance Recovery After Slipping
… peak slip velocity) and slip outcome (fall or recovery) were compared between groups. Obese individuals experienced 8.25% faster slips than non-obese individuals in terms of average slip velocity (p=0.022). Obesity did not affect slip distance, slip duration or peak slip velocity. Obese …

Effects of Obesity on Balance Recovery in Response to Small Postural Perturbations
… was to investigate the effects of obesity on balance recovery in response to small forward postural perturbations. Twenty male participants, including 10 lean (mean BMI ± SD: 21.9 ± 1.4) and 10 obese (BMI: 33.2 ± 2.3), were exposed to two types of postural perturbations (force impulses applied …

Effects of Obesity and Age on Muscle Strength, Gait, and Balance Recovery
… of obesity and age on muscle strength, gait, and balance recovery. Three experimental studies were conducted. The purpose of the first study was to investigate the effects of obesity and age on extension and flexion strength at the hip, knee, and ankle. Absolute strength among obese participants …

Understanding the effects of obesity and age on likelihood of tripping and subsequent balance recovery
… age on the likelihood of tripping and subsequent balance recovery. Four experimental studies were conducted. The purpose of the first study was to investigate the effects of obesity, age and gender on the likelihood of tripping during level walking. Likelihood of tripping was assessed with median …

Association of Obesity and Lower Limb Muscle Strength and Power with Balance Recovery from a Forward Leaning Position
… measured the ability of older adults to recover balance when released from a forward leaning position. This forward leaning assessment was used as a surrogate for a balance recovery from a fall. The maximal body lean angle from which the subject could recover their balance was referred to as …

An experimental and simulation based approach toward understanding the effects of obesity on balance recovery from a postural perturbation
… important to understand how obesity influences balance recovery from a postural perturbation. There is limited information on the effects of obesity on balance recovery, and the limited available information is ambiguous. Therefore, the purpose of the research within this dissertation was to …

Maximum Absolute and Relative Joint Torques during Recovery from a Simulated Trip
… have shown that obesity negatively affects balance during quiet standing, yet little is known about its effect on the ability to recover after a postural perturbation. The purpose of this thesis was to investigate the effects of obesity on single-step balance recovery from an incipient …

Experimental and simulation-based assessment of the human postural response to sagittal plane perturbations with localized muscle fatigue and aging
… of factors that have a deleterious effect on balance and postural control such as LMF and aging. An initial study was conducted to investigate the effects of LMF and aging on balance recovery from a postural perturbation without stepping. Sagittal plane postural perturbations were administered …

Aging effect on successful reactive-recovery from unexpected slips: a 3D lower extremity joint moment analysis
… generation in both normal walking and reactive-recovery conditions was examined. Dataset collected during previous slip and fall experiments, which were conducted in a typical gait analysis setting, were analyzed in current study. All the participants were subjected to the screening criteria, …

The effect of perturbation warning on attention switching abilities during dual-task performance in young and older adults
… performed a tracking task while recovering their balance from a support surface translation. For half of the trials, an auditory warning was presented to inform participants of the upcoming translation. Performance was quantified through electromyographic (EMG) recordings of the lower limb …

Reactive stepping strategies following lateral surface translations in individuals with a unilateral lower limb amputation
Following a loss of balance, individuals may utilize specific stepping strategies to prevent themselves from falling. The stepping strategies that are used by lower limb amputees, which likely consist of unique properties because of the limitations when using a prosthesis, have not been thoroughly …

Application of a model of cerebellar function to the maintenance of human upright posture
… systems can realistically model human posture balance recovery is evaluated by simulating human postural maintenance during backward translation of a support surface. The simulation is compared with actual human postures and movements. The simulation realizes the ankle and hip strategy that …

The Influence of Occupational Footwear on Slip Responses
… of this study was to investigate how OF affects balance recovery strategies and slip outcome in response to an unexpected slip during walking. Twenty-five individuals (13 males, 12 females) completed a total of 12 walking trials at a self-selected pace in either barefoot (BF) or while wearing OF. …

Development of a Locomotion and Balancing Strategy for Humanoid Robots
… the chance of collisions. Several human-inspired recovery strategies have been studied and adopted to humanoid robots in order to face unexpected and avoidable perturbations. These strategies include hip, ankle, and stepping, however, the use of the arms as a recovery strategy did not enjoy as …

Transition between single and multiple stepping strategies in forward fall recovery
Background. Following a balance disturbance, one or more steps are often taken. Studies have shown that older adults are more likely than young adults to take multiple steps, and that number of steps is a predictor of fall risk. In order to better understand how a stepping strategy is chosen, we …
