Many low-back patients undergo electromyography (EMG)-based evaluations of muscle performance but present to the clinic after being prescribed muscle relaxants. The question that needed to be addressed was, do centrally acting muscle relaxants (methocarbamol; Robaxin) affect the EMG spectral indices of muscle fatigue that are often used to assess muscle performance. Participants performed an isometric spine extension protocol involving a 30 s fatigue exertion trial, then 1 min rest, and finally… Expand
Influence of Trunk Extensor Muscles Fatigue on the Postural Control and Sensorimotor Integration
Results indicate that proprioceptive information remains reliable after the used fatigue protocol, allowing subjects to keep a satisfactory straight posture. Expand
Lumbar and cervical erector spinae fatigue elicit compensatory postural responses to assist in maintaining head stability during walking.
Overall, the results of this study suggest that erector spinae fatigue differentially altered segmental attenuation during walking, according to the level of the upper body that was fatigued and the direction that oscillations were attenuated. Expand

Electromyographic Median Frequency Changes During Isometric Contraction of the Back Extensors to Fatigue
Endurance appears to be limited by the most fatigable region of the muscle group, and MFGRAD is a suitable technique for monitoring back muscle fatigue, even when it is determined over a submaximal time period. Expand
Myoelectric signal characteristics in lumbar back muscles during fatigue
Abstract The present study examines the possible differences in electrophysiological manifestations of low back muscle fatigue between symptomatic (CON) and symptomatic (LB) persons by means of EMGExpand
Fatigue, recovery, and low back pain in varsity rowers.
Results from this study demonstrate that low back pain and asymmetrical muscle function in rowers can be assessed on the basis of EMG spectral analysis. Expand
Fatigue of the Erector Spinae Muscles: A Quantitative Assessment Using “Frequency Banding” of the Surface Electromyography Signal
Changes in the 5–30 Hz band of the EMG power spectrum provide a more reliable and linear index of fatigue in the erector spinae muscles than do changes in median frequency. Expand

The practical implication of this work is that the experimental condition must have sufficiently large changes in MedPF (signal)--at least larger than the variability inherent in theMedPF (noise)--to constitute a valid measure. Expand
Use of the surface EMG signal for performance evaluation of back muscles
The pattern of fatigue exhibited by the six median frequency curves can be used to distinguish individuals who have low-back pain from those who do not with an accuracy of at least 84%. Expand
Lumbar Muscle Fatigue and Chronic Lower Back Pain
A Back Analysis System for objectively measuring local fatigue in the back extensor muscles is presented and the applicability of this technique as a treatment outcome measure and diagnostic screening method for lower back pain patients is discussed. Expand
Classification of Low Back Pain With the Use of Spectral Electromyogram Parameters
The use of spectral parameters to classify subjects with low back pain from those without appears to have merit and models based on 60% ofmaximum voluntary contraction demonstrated results comparable with those of previous research using 40% and 80% of maximum voluntary contraction. Expand
Myoelectrical manifestations of localized muscular fatigue in humans.
The essence and results of pertinent publications are discussed with emphasis on the relationship between the spectral shift of the myoelectric signal, conduction velocity of muscle fibers, pH of the interstitial fluid and blood flow within a muscle. Expand
Reproducibility of isometric trunk extension torque, trunk extensor endurance, and related electromyographic parameters in the context of their clinical applicability
The reproducibility of measurements of maximum trunk extension force, trunk extension endurance, and related electromyographic parameters was investigated and the clinical applicability of the parameters studied is severely limited by a lack of reproducible. Expand
