MIMU sensors for joint kinematic estimation: anatomical landmarking and frame correction
(2016-08-09)
The ability to capture human motion allows researchers to evaluate an individual’s gait. Gait can be measured in different ways, from camera-based systems to Magnetic and Inertial Measurement Units (MIMU). The former uses ...
An investigation of lower limb joint powers as a predictive measure of countermovement vertical jump height.
(2016-09-07)
Measuring and tracking athletic performance is crucial to an athlete’s development and the countermovement vertical jump is often used to measure athletic performance, particularly lower limb power. The linear power developed ...
Effect of Foot Shells on Mechanical Properties of Prosthetic Foot Systems
Prosthetic foot systems are typically composed of both structural keel and foot shell components. The interaction between these components is considered by the prosthetic device industry with respect to designing higher ...
Quadriceps Avoidance Characteristics of Persons with a Reconstructed Anterior Cruciate Ligament during a Forward Lunge
(2015-08-26)
Anterior cruciate ligament (ACL) tears are injuries that often require surgery and physical therapy. Previous research have shown that patients after ACL reconstruction develop a compensatory mechanism called quadriceps ...
Two muscles are better than one: Co-contraction engages antagonistic muscles in response to perturbation
Co-contraction is a common strategy when performing difficult or unstable motor tasks. For example, we co-contract muscles of the arm when generating downward force to turn a screw and co-contract muscles of the leg when ...
Strength Requirements and Energy Efficiency of Different Stair-Stepping Strategies in Persons With Chronic Stroke and Healthy Adults
(2013-10-01)
The majority of stroke survivors return to living in the community; however, muscle weakness and cardiovascular deconditioning can restrict mobility, limit community access and independence, particularly when challenging ...
Improved Accuracy in Optical Motion Capture Measurements Leads to Increased Sensitivity to Kinematic Changes
(2016-08-18)
Clinical optical motion capture allows us to obtain kinematic and kinetic outcome measures that aid clinicians in diagnosing and treating different pathologies affecting healthy gait. The long term aim for gait centres is ...
Factors Affecting the Stability of Reverse Shoulder Arthroplasty
(2012-01-04)
Reverse shoulder arthroplasty is a relatively new procedure that is used to treat shoulders with massive rotator cuff tears combined with arthritis, a condition that is not well managed using conventional shoulder arthroplasty. ...
Biomechanical and physical requirements of stair negotiation with respect to aging and stroke
(2011-08-25)
The ability to safely and efficiently negotiate stairs is an essential skill for independent ambulation. To date, basic research to identify biomechanical and physical costs is limited in older adults. In persons with ...
Deformable Link Segment Model for Analysis of Prosthetic Foot-ankle Components
Recent literature suggests that passive prosthetic foot-ankle devices, when optimized, may provide similar energy performance as the natural foot, but this has yet to be realized with current designs. Of concern is the ...
