Journal Article
Gill, N., O'Leary, T., Roberts, A., Liu, A., Roerdink, M., Greeves, J., & Jones, R. (in press). Enforcing walking speed and step-length affects joint kinematics and kinetics in male and female healthy adults. Gait & Posture, 103, 223-228. https://doi.org/10.1016/j.gaitpost.2023.05.025

Individuals increase walking speed by increasing their step-length, increasing their step-frequency, or both. During basic training military recruits are introduced to marching "in-step", and thus the requirement to walk at fixed speeds and step-leng...

The immediate effect of backward walking on external knee adduction moment in healthy individuals (2022)
Journal Article
adduction moment in healthy individuals. Journal of Healthcare Engineering, https://doi.org/10.1155/2022/4232990

Backward walking (BW) has been recommended as a rehabilitation intervention to prevent, manage, or improve diseases. However, previous studies showed that BW significantly increased the first vertical ground reaction force (GRF) during gait, which mi...

Prosthetics and Orthotics International, 46(1), 54-60. https://doi.org/10.1097/pxr.0000000000000053

Background: Changes in residuum volume are a common problem in lower-limb amputees during prosthesis usage, and can lead to poor suspension, impaired gait, and tissue damage. Residuum volume can be affected by the in-socket air pressure, which will i...

Postural balance in individuals with knee osteoarthritis during stand-to-sit task (2021)
Journal Article
Fu, S., Duan, T., Hou, M., Yang, F., Chai, Y., Chen, Y., …Chen, L. (2021). Postural balance in individuals with knee osteoarthritis during stand-to-sit task. Frontiers in Human Neuroscience, 15, 760960. https://doi.org/10.3389/fnhum.2021.760960

Objective: Stand-to-sit task is an important daily function, but there is a lack of research evidence on whether knee osteoarthritis (knee OA) affects the postural balance during the task. This study aimed to compare individuals with knee OA and asym... Read More about Postural balance in individuals with knee osteoarthritis during stand-to-sit task.

The immediate effects of foot orthosis geometry on lower limb muscle activity and foot biomechanics (2021)
Journal Article
