Predictive balance control during backward walking and effects of a haptic input based intervention on predictive balance control during walking
… during walking. Understanding and improving balance control during walking can help reduce falls. One way of improving balance control may be to add haptic input during walking and including backward and tandem walking in gait training programs. Purpose The overall purpose of this study was …

Kalman filtering of IMU sensor for robot balance control
… information on the orientation of a robot for balance control. A test bed was created to characterize the random noise and errors inherent to orientation sensing in the MicroStrain 3DM-GX1 IMU for static cases as well as after experiencing an impact force. Balance simulations were performed to …

Attention focus and balance control in young and older adults
This thesis investigated attention focus and balance control in eighteen healthy young adults and eighteen healthy older adults. All participants performed sixteen consecutive trials of a balance task which involved standing for 30-s on an unstable platform that could rotate only in the roll …

Design and implementation of balance control in a humanoid robot
A proportional derivative control strategy was developed for the purpose of achieving balance in a humanoid robot. An artificial muscle model was adapted which modified physiological parameters for the purpose of controlling a lightweight robot skeleton. Gains were modified as a function of joint …

Reactive Balance Control after Stroke: Towards Enhanced Clinical Understanding and Assessment
… goal for those with stroke, of which balance control is a key determinant. The risk of falls post-stroke is high and fall rates rise dramatically soon after discharge from the hospital. Previous research has revealed the essential role that reactive balance control, specifically the …

Balance control and locomotion planning for humanoid robots using nonlinear centroidal models
Balance control approaches for humanoid robots have traditionally relied on low-dimensional models for locomotion planning and reactive balance control. Results for the low-dimensional model are mapped to the full robot, and used as inputs to a whole-body controller. In particular, the linear …

Angular momentum in turns and abrupt starts : strategies for bipedal balance control
… of elderly has increased and understanding balance control in healthy subjects will be more important. In addition, humanoid bipeds are rapidly becoming a more common part of our everyday life. Therefore, they must also be able to navigate our environments adroitly if they are to assist us …

Impact of Spasticity on Balance Control During Quiet Standing in Persons Post-Stroke
Statement of the problem: Balance impairments and falls are common among people with stroke. Muscle spasticity is also common and may influence balance control. However, the effect of spasticity on balance control among people with stroke is not well understood. Methods: Twenty-seven post-stroke …

Contribution of Modified Visual Gain to Human Balance Control During Quiet, Upright Stance
… visual feedback indirectly can improve postural control, such as by providing individuals with biofeedback during balance tasks. When studies have manipulated vision directly, the conditions have been restricted to include an absence of visual feedback and sway referenced paradigms. Therefore, …

Development and evaluation of postural control models for lifting motions and balance control
… novel motion simulation model using fuzzy logic control is presented. This model was motivated by the fact that humans use linguistic terms to guide their behaviors while fuzzy logic provides mathematical representations of linguistic terms. Specifically in this model, fuzzy logic was used to …

Giving the head a hand : constructing a microworld to build relationships with ideas in balance control
… this potential through children learning about Balance Control in Dynamic Systems (BCDS), which adds a particular value given that BCDS is considered too complex for young learners. A Balance Control Microworld was created to help learners think about how to program physical robots to perform …

The effect of the Nintendo Wii Fit on the balance control and gross motor function of children with spastic hemiplegic cerebral palsy
Background: Balance and postural control are an integral part of gross motor function in activities of daily living. Studies have shown that children with hemiplegic cerebral palsy have poor directional specificity as well as problems with the temporal and spatial modulation of appropriate muscle …

Sensory re-weighting for balance control and the effects of ankle foot orthoses and stance width: A comparison of people with diabetic peripheral neuropathy and healthy participants
… stability contributing to falls risk. Standing balance requires the integration of sensory information from somatosensory, vestibular and visual systems. Alterations in distal sensory input may result in a re-weighting of the effectiveness of remaining sensations in mediating a stabilising …

The Effect of Subthreshold Vibration on Lateral Reactive Balance
… subthreshold vibratory noise improves standing balance control in a diverse range of populations (i.e., young adults, older adults, and persons with diabetic neuropathy). However, there is limited literature examining whether these effects extend to reactive balance contexts. Therefore, the …

Gait and Postural Analysis in Healthy Young Adults and People with Parkinson's Disease
… used to assess potential abnormalities in the balance control system and to understand how the balance control system changes with time. However, compared to other medical fields of study, postural analysis is relatively new [1]. In fact, although widely used in clinical and research studies, …

Estimation of ground reaction force and zero moment point on a powered ankle-foot prosthesis
… extremity amputees, such as a lack of adequate balance control during standing and walking. The ground reaction force (GRF) and the zero moment point (ZMP) are known to be basic parameters in bipedal balance control. This thesis focuses on the estimation of these parameters using two prostheses, …

Design of novel timing paradigms for investigation and rehabilitation of predictive and reactive postural response for hemiparetic stroke
… tasks, and understanding of timing effects in balance control may contribute to refine balance retraining paradigms for hemiparetic stroke. This thesis opens with a review on predictive and reactive modes of balance control. The initial review concludes there is unexplored potential in …

Quantifying Human Balance Performance and Control to Inform Therapy
Maintaining balance is essential for daily activities and overall health. However, balance capability often declines with age or due to health conditions such as stroke, increasing fall risk. Falls among older adults are a major public health concern, affecting 14 million older adults annually in …

Effect of Age on Visual Dependence for Spatial Orientation and Postural Control
Effective spatial orientation and postural control requires the integration of proprioceptive, vestibular and visual inputs. Increased visual dependence has been reported in older adults but the underlying mechanisms remain unknown. The aims of this research were to investigate the methodological …
