Modulation and modeling of anticipatory postural adjustments for gait initiation in persons with Parkinson's disease
… impair quality of life is freezing of gait (FOG). Currently, the treatments for the motor symptoms of PD (e.g., levodopa, deep brain stimulation) are ineffective at managing FOG as the disease progresses. These treatments only target the cortical-striatal pathways of volitional movement …

Dynamic Postural Stability During Gait Initiation in Individuals with Chronic Ankle Instability: The Influence of Walking Velocity
… in individuals with CAI during varying speeds of gait initiation (GI). There were twenty eight voluntary subjects, 14 (M8:F6) subjects with CAI and 14 (M8:F6) control subjects (healthy young athletes, HYA). CAI was assessed using the Foot and Ankle Ability Measure (FAAM) tool. Control subjects had …

Differences in Balance and Muscle Activation Strategies during Gait Initiation at Different Speeds between Young and Middle-Aged Adults
… on balance variables and muscle activity during gait initiation in the MA compared to YA using an instrumented walkway. The objectives of this study were to assess the effects of age and speed on balance by measuring a) the Center of Pressure (COP) in two planes: COPx (sagittal) and COPy …

Influence of Vibratory Plantar Stimulation on Cortical Motor Planning and Spatiotemporal Step Parameters
… input for anticipatory postural adjustments and gait initiation. Although previous literature suggests that plantar vibratory stimulation can improve balance and reduce gait variability, its influence on cortical motor planning remains unclear. This study examined whether augmenting plantar …

Dynamic Postural Control In Individuals With Multiple Concussions
… in this population. The transitional movement of gait initiation, literally the act of starting to walk, has effectively identified impairments in postural control in a wide range of neurologically impaired populations (e.g., post-stroke, Parkinson's, aging). Therefore, the purpose of this study …

BIOMECHANICAL MARKERS AS INDICATORS OF POSTURAL INSTABILITY PROGRESSION IN PARKINSON'S DISEASE
… if biomechanical assessment of a dynamic task, gait initiation, could provide preclinical indication of postural instability in PD. Specific Aim 1 determined that some biomechanical postural sway variables showed evidence of preclinical postural instability and increased with PD progression. …

Impairment in Dynamic Postural Control Following an Acute Lateral Ankle Sprain
… Dynamic postural control will be evaluated by gait initiation, which will be assessed using the Vicon system and then compared to matched healthy control values. MANOVA revealed no significant difference in dynamic postural control following a lateral ankle sprain when compared to control …

The biomechanical changes in gait and posture as a result of the total knee arthroplasty
… performed three tasks, which were steady state gait, gait initiation and quiet standing whilst their kinematics and kinetics were measured. At these assessments patients completed self-reported questionnaires. Only 10 completed all assessments and were therefore considered in the final analysis. …

Gait and Postural Analysis in Healthy Young Adults and People with Parkinson's Disease
… body is an inherently unstable system. In fact, gait and balance impairments lead to loss of mobility, falls, and a diminished quality of life. Advanced age, orthopedic and neurological conditions affect overall balance control, which leads to gait and balance impairment [1, 2]. In fact, …

Sensory and Cognitive Influences on Oculomotor and Whole-body Coordination during Standing Turns
… however suppressing eye movements delayed gait initiation and decreased stepping frequency throughout the turn. Next we examined the influence of neck muscle vibration on turning and found that stimulating neck proprioceptors to evoke the CNS perception of head rotation with respect to the …

NEW PERSPECTIVES ON POSTURAL CONTROL IN CHILDREN AND ADULTS
… study; the others (RA-2 and RA-3) focused on gait initiation (GI). Specifically, I started a study (RA-2) to assess the existence of Anticipatory Postural Adjustments (APAs) in healthy toddlers that could be relevant in anticipating the diagnosis of paediatric diseases. Finally, I looked at …

Sitting, Standing and Starting: Detailing Postural Control and Gait Anticipation for Children with Hemiplegic Cerebral Palsy
… uninvolved side for stability during balance and gait. Much is still unknown about the biomechanical characteristics of asymmetry in the lower limbs. There are a few previous research studies completed in biomechanics labs that highlight some gaps in knowledge regarding our understanding of …
