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 ...
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 ...
Obesity is associated with higher absolute tibiofemoral contact and muscle forces during gait with and without knee osteoarthritis
(Elsevier, 2016-01)
Background
Obesity is an important risk factor for knee osteoarthritis initiation and progression. However, it is unclear how obesity may directly affect the mechanical loading environment of the knee joint, initiating ...
Activation amplitude patterns do not change for back muscles but are altered for abdominal muscles between dominant and non-dominant hands during one-handed lifts
(SpringerLink, 2009-05)
It is assumed when lifting with the dominant hand that the relationship between contralateral and ipsilateral trunk muscle responses are similar to when lifting with the non-dominant hand. The purpose of this study was to ...
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 ...
Electromyographic assessment of trunk muscle activation amplitudes during a simulated lifting task using pattern recognition techniques
(Elsevier, 2009-12)
This study sought to determine the patterns of neuromuscular response from 24-trunk muscle sites during a symmetrical lift and replace task. Surface electromyograms (EMG) and kinematic variables were recorded from 29 healthy ...
