Activation amplitude and temporal synchrony among back extensor and abdominal muscles during a controlled transfer task: comparison of men and women
(Elsevier, 2012-08)
Muscle synergies are important for spinal stability, but few studies examine temporal responses of spinal muscles to dynamic perturbations. This study examined activation amplitudes and temporal synergies among compartments ...
Neuromuscular alterations exist with knee osteoarthritis presence and severity despite walking velocity similarities
(Elsevier, 2011)
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 ...
Maximal voluntary isometric contraction exercises: A methodological investigation in moderate knee osteoarthritis
(Elsevier, 2011)
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 ...
Asymptomatic and symptomatic individuals with the same radiographic evidence of knee osteoarthritis walk with different knee moments and muscle activity
(Wiley, 2016-11-01)
There is an established discordance between the structural joint damage and clinical symptoms of knee osteoarthritis; however, there has been little investigation into the differences in joint level biomechanics and muscle ...
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 ...
Explaining the hip adduction moment variability during gait: Implications for hip abductor strengthening
(Elsevier, 2009)
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 ...
Differences in Abdominal Muscle Activation Patterns of Younger and Older Adults Performing an Asymmetric Leg-Loading Task
(Elsevier, 2009-11)
Objectives: To determine whether differences exist between younger (20-50 years) and
older adults ( 65 years) in abdominal muscle amplitudes, temporal patterns, and threedimensional
(3D) pelvic motion, while performing ...
The interpretation of abdominal wall muscle recruitment strategies change when the electrocardiogram (ECG) is removed from the electromyogram (EMG)
(Elsevier, 2009-04)
The purpose of this study was to determine the effect of the ECG artifact on low-level trunk muscle activation amplitudes and assess the effectiveness of two methods used to remove the ECG. Simulations were performed and ...
Trunk neuromuscular pattern alterations during a controlled functional task in a low back injured group deemed ready to resume regular activities.
(IOS Press, 2014)
BACKGROUND: Trunk neuromuscular alterations have been found in those with chronic low back pain, but less well studied are whether responses are altered in those deemed recovered following an injury. Furthermore, coordinated ...
Pre-operative muscle activation patterns during walking are associated with TKA tibial implant migration.
(Elsevier, 2012-11)
Background
Gait biomechanical variables have been associated with total knee arthroplasty tibial implant migration measured with Radiostereometric Analysis (RSA), but no studies have examined the role of the periarticular ...
