Sit-to-stand transfer mechanics in healthy older adults: A comprehensive investigation of a portable lifting seat device.
(Taylor & Francis, 2014)
Purpose: To evaluate lower extremity mechanics and muscle activation associated with the sit-to-stand transfer using a portable lifting-seat device and to compare these data to an unassisted transfer in healthy young and ...
Changes in Knee Joint Muscle Activation Patterns during Walking Associated with Increased Structural Severity in Knee Osteoarthritis
Purpose To determine whether alterations in knee joint muscle activation patterns during gait were related to structural severity determined by Kellgren–Lawrence (KL) radiographic grades, for those with a moderate knee ...
Maximal voluntary isometric contraction exercises: A methodological investigation in moderate knee osteoarthritis
Purpose: The objectives were, (i) to determine whether differences exist in relative activation amplitudes for participants with asymptomatic knees and participants with moderate medial compartment knee osteoarthritis ...
Neuromuscular alterations exist with knee osteoarthritis presence and severity despite walking velocity similarities
Background Neuromuscular strategies during walking in individuals with knee osteoarthritis are being explored for diagnostic information; however, isolating differences to disease progression is difficult given walking ...
Explaining the hip adduction moment variability during gait: Implications for hip abductor strengthening
Background There is emerging interest in hip abductor function during gait and its potential relationship to knee joint pathology. During gait, the hip abductor muscles are primarily responsible for generating moments of ...
Reliability of Principal Components and Discrete Parameters of Knee Angle and Moment Gait Waveforms in Individuals with Moderate Knee Osteoarthritis
Gait measures are used to evaluate change in patients with knee osteoarthritis (OA), but reliability has not been fully established in this population. This study examined test-retest reliability of knee angle and moment ...
Hip abductor function in individuals with medial knee osteoarthritis: Implications for medial compartment loading during gait
Background Hip abductor muscles generate moments of force that control lower extremity frontal plane motion. Strengthening these muscles has been a recent trend in therapeutic intervention studies for knee osteoarthritis. ...
Reliability of surface electromyographic recordings during walking in individuals with knee osteoarthritis
To determine test–retest reliability of a surface electromyographic protocol designed to measure knee joint muscle activation during walking in individuals with knee osteoarthritis (OA). Twenty-one individuals with moderate ...
