Neuromusculoskeletal modeling: estimation of muscle forces and joint moments and movements from measurements of neural command.
This paper provides an overview of forward dynamic neuromusculoskeletal modeling. The aim of such models is to estimate or predict muscle forces, joint moments, and/or joint kinematics from neuralExpand

The isometric functional capacity of muscles that cross the elbow.
We hypothesized that muscles crossing the elbow have fundamental differences in their capacity for excursion, force generation, and moment generation due to differences in their architecture, momentExpand

Dynamic stability in the anterior cruciate ligament deficient knee
Some individuals can stabilize their knees following anterior cruciate ligament rupture even during activities involving cutting and pivoting (copers), others have instability with daily activitiesExpand

Abnormal muscle coactivation patterns during isometric torque generation at the elbow and shoulder in hemiparetic subjects.
To study abnormal spatial patterns of muscle activation in hemiparetic stroke, we compared EMG activity in paretic and contralateral elbow and shoulder muscles of 10 hemiparetic subjects during 1.5-sExpand

Variation of muscle moment arms with elbow and forearm position.
We hypothesized that the moment arms of muscles crossing the elbow vary substantially with forearm and elbow position and that these variations could be represented using a three-dimensional computerExpand

Strategies of muscular support of varus and valgus isometric loads at the human knee.
In this paper we studied how subjects activate their muscles in response to static varus and valgus loads at the knee. The muscles' contributions to the external moments were estimated using an EMGExpand

Characteristics of synergic relations during isometric contractions of human elbow muscles.
We studied the patterns of EMG activity in elbow muscles in three normal human subjects. The myoelectrical activity of 7-10 muscles that act across the human elbow joint was simultaneously recordedExpand

Ankle inversion injury and hypermobility: effect on hip and ankle muscle electromyography onset latency.
OBJECTIVE Changes in reflexes associated with chronically sprained ankles were examined by measuring the reflex response latency of hip and ankle muscles during instantaneous ankle/foot inversion. Expand

Laxity in healthy and osteoarthritic knees.
OBJECTIVE Although it is a cause of osteoarthritis (OA) in animal models, laxity in human knee OA has been minimally evaluated. Ligaments become more compliant with age; whether this results inExpand

How muscle architecture and moment arms affect wrist flexion-extension moments.
The purpose of this investigation was to determine how the moment arms and architecture of the wrist muscles influence their isometric moment-generating characteristics. A three-dimensional computerExpand
