Neck Muscle EMG-Force Relationship and Its Reliability During Isometric Contractions
BACKGROUND Susceptible to injury, the neck is subject to scientific investigations, frequently aiming to elucidate possible injury mechanisms via surface electromyography (EMG) by indirectly estimating cervical loads. Accurate estimation requires that the EMG-force relationship is known and that its measurement error is quantified. Hence, this study examined the relationship between EMG and iso...
متن کاملA new isometric quadriceps-strengthening exercise using EMG-biofeedback.
A new isometric contraction quadriceps-strengthening exercise was developed to restore the quadriceps strength lost after knee surgery more rapidly. This study evaluated the results of this new method. Patients were taught to perform the isometric quadriceps-strengthening exercise in the unaffected knee in the supine position, and then they performed it in the affected knee. First, patients wer...
متن کاملMotor unit control properties in constant-force isometric contractions.
1. The purpose of this study was 1) to characterize the decrease observed in mean firing rates of motor units in the first 8-15 s of isometric constant-force contractions and 2) to investigate possible mechanisms that could account for the ability to maintain force output in the presence of decreasing motor unit firing rates. 2. The decrease in mean firing rates was characterized by investigati...
متن کامل[Application of EMG biofeedback to patients with mandibular dysfunction. Part 2. Validity of frontal EMG biofeedback].
The purpose of this study was to investigate the mean integral EMG level of the masseter muscle, which was obtained from the EMG biofeedback of the frontal muscle of those patients whom once had a case of mandibular dysfunction, and to use this as an effective means of treatment. Furthermore, the correlation between the psychological characteristics of mandibular dysfunction patients and EMG bi...
متن کاملThe Usability and Efficiency Human-Computer Interface in Cervical Spinal Cord injury by Game-based Electromyography Biofeedback and EMG Biofeedback
Background and Aims: The purpose of this study was to compare the efficacy and usability of human-computer interface in cervical spinal cord injury with two computer games based and EMG biofeedback. Methods: The sample size was 20 participants (healthy and spinal cervical lesions) who were selected as available. The statistical population of the study was spinal cord injury patients referred t...
