Fall Risk for Older Adults is Impacted by the Frequency and Intensity of Physical Activity Open
Engaging in physical activity is known to prevent falls in older adults, however the relative influence of the intensity, duration and frequency of physical activity is unclear. This study investigated the relationship between fall history…

The Minimum Number of Strides Required for Reliable Gait Measurements in Older Adult Fallers and Non-Fallers Open
While the value of walking gait metrics collected using pressure-sensing walkways has shown promise for fall risk assessment, there is no consensus on the minimum number of strides required to obtain reliable metrics. This study aimed to d…

The Determination of On-Water Rowing Stroke Kinematics Using an Undecimated Wavelet Transform of a Rowing Hull-Mounted Accelerometer Signal Open
Boat acceleration profiles can provide valuable information for coaches and practitioners to make meaningful technical interventions and monitor the determinants of success in rowing. Previous studies have used simple feature detection met…

Erosion of Stumble Correction Evoked with Superficial Peroneal Nerve Stimulation in Older Adults during Walking Open
In healthy young adults, electrical stimulation of the superficial peroneal cutaneous nerve (SPn) innervating the dorsum of the foot has been shown to elicit functionally relevant reflexes during walking that are similar to those evoked by…

A Comparison of Bioelectric and Biomechanical EMG Normalization Techniques in Healthy Older and Young Adults during Walking Gait Open
This study compares biomechanical and bioelectric electromyography (EMG) normalization techniques across disparate age cohorts during walking to assess the impact of normalization methods on the functional interpretation of EMG data. The b…

Wheelchair Rugby Sprint Force-Velocity Modeling Using Inertial Measurement Units and Sport Specific Parameters: A Proof of Concept Open
Background: Para-sports such as wheelchair rugby have seen increased use of inertial measurement units (IMU) to measure wheelchair mobility. The accessibility and accuracy of IMUs have enabled the quantification of many wheelchair metrics …

A Simple and Valid Method to Calculate Wheelchair Frame Rotation Using One Wheel-Mounted IMU Open
Wheelchair sports have been using Inertial Measurement Units (IMU) to measure mobility metrics during training, testing and competition. Presently, the most suitable solution to calculate wheelchair speed and frame rotation is the 3IMU met…
View article: NOVEL INSIGHTS ON THE RELATIVE IMPORTANCE OF CLINICAL AND GAIT MEASURES FOR DETECTING FALL RISK IN OLDER ADULTS
NOVEL INSIGHTS ON THE RELATIVE IMPORTANCE OF CLINICAL AND GAIT MEASURES FOR DETECTING FALL RISK IN OLDER ADULTS Open
We sought to extend recent research that explored model-based approaches for combining clinical and gait measures to determine the most sensitive grouping for retrospectively classifying fallers from non-fallers which resulted in a model w…

Age-related erosion of obstacle avoidance reflexes evoked with electrical stimulation of tibial nerve during walking Open
In young healthy adults, characteristic obstacle avoidance reflexes have been demonstrated in response to electrical stimulation of cutaneous afferents of the foot during walking. It is unknown whether there is an age-related erosion of th…
View article: Targeted use of technology to assist with fall risk classification in older adults
Targeted use of technology to assist with fall risk classification in older adults Open
Falling is a significant risk for older adults in Canada. Suffering a fall can result in injury and reduced quality of life which may include loss of autonomy. Additionally, injuries and rehabilitation from falls are a significant resource…
View article: Comparing executive function, evoked hemodynamic response, and gait as predictors of variations in mobility for older adults
Comparing executive function, evoked hemodynamic response, and gait as predictors of variations in mobility for older adults Open
These results are in keeping with assertions that diminished executive control is related to fall risk. Notably, the group differences observed in prefrontal cortical activation and in gait parameters may ultimately precede those observed …
