High-pass filtering to remove electrocardiographic interference from torso EMG recordings
(Elsevier, 1993-01)
SummaryRemoval of electrocardiographic (ECG) contamination of electromyographic (EMG) signals from torso muscles is often attempted by high-pass filtering. This study investigated the effects of the cut-off frequency used ...
EMG Biofeedback as a Tool for Simulating the Effects of Specific Leg Muscle Weakness on a Lifting Task
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1999-12)
This study investigated the use of EMG biofeedback to simulate weakened rectus femorii and gastrocnemii muscles during the performance of a lifting task. Eight healthy women performed 15 kg free-style lifts from floor ...
Work-related musculoskeletal disorders: Comparison of data sources for surveillance
(John Wiley & Sons, Inc., 1997-05)
Work-related upper extremity musculoskeletal disorders “associated with repeated trauma” account for more than 60% of all newly reported occupational illness, 332,000 in 1994 according to the U.S. Department of Labor. These ...
Reliability of nerve conduction studies among active workers
(John Wiley & Sons, Inc., 1999-10)
Nerve conduction studies play an important role in clinical practice and research. Given their widespread use, reliability of tests merits careful attention. We assessed interexaminer and intraexaminer reliability of median ...
The relationship between body mass index and the diagnosis of carpal tunnel syndrome
(Wiley Subscription Services, Inc., A Wiley Company, 1994-06)
Increased weignt and, more recently, body mass index (BMI), have been suggested as risk factors for carpal tunnel syndrome (CTS). In an effort to determine the relative risk (RR) of obesity in the development of CTS, 949 ...
A strategy for evaluating occupational risk factors of musculoskeletal disorders
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1992-03)
There is a large and increasing incidence of work-related muscoloskeletal disorders, both upper extremity cumulative trauma disorders and low back pain. Several occupational risk factors have been linked with the development ...
A kinematic model of the human hand to evaluate its prehensile capabilities
(Elsevier, 1992-02)
A kinematic model has been developed for simulation and prediction of the prehensile capabilities of the human hand. The kinematic skeleton of the hand is characterized by ideal joints and simple segments. Finger-joint ...
Lumbar muscle size and locations from CT scans of 96 women of age 40 to 63 years
(Elsevier, 1990-02)
Computed tomography scans of 96 women aged between 40 and 63 years were systematically measured to determine torso muscle moment arms and cross-sectional areas at L2/L3, L3/L4 and L4/L5 disc levels. The major findings were ...
Median and ulnar nerve conduction studies among workers: Normative values
(John Wiley & Sons, Inc., 1998-08)
To determine normative values for nerve conduction studies among workers, we selected a subset of 326 workers from 955 subjects who participated in medical surveys in the workplace. The reference cohort was composed ...
Analysis of the tonic vibration reflex: influence of vibration variables on motor unit synchronization and fatigue
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1997-05)
The influence of vibration frequency (40, 80, 100, 120, 150, or 200 Hz) at selected displacement amplitudes (0.2, 0.3 mm) on tonic vibration reflex (TVR) characteristics was investigated. The degree of synchronization of ...
