Relaxation phenomenon in lumbar trunk muscles during lateral bending.
This paper reports myoelectric activity measurements in the lumbar trunk muscles when subjects performed tasks involving various degrees of lateral bending. Biomechanical model analyses were made to estimate the tensions in the lumbar trunk muscles required to perform those tasks. The tensions and the activity measurements were compared to see if a muscle relaxation phenomenon occurred. A relax...
متن کاملSpasm and flexion-relaxation phenomenon response to large lifting load during the performance of a trunk flexion-extension exercise
BACKGROUND The flexion relaxation phenomenon (FRP) has been widely investigated. Nevertheless, no study has been reported on the FRP as well as spasm response to large lifting load. The aim of this study was to evaluate the effect of large lifting load on the FRP response and spasm during execution of a flexion-extension exercise. METHODS Twenty-two healthy male university students without lo...
متن کاملEvaluation of the flexion relaxation phenomenon of the trunk muscles in sitting.
STUDY DESIGN A normative, single-group study was conducted. OBJECTIVE To investigate the flexion relaxation phenomenon in the thoraco-lumbopelvic muscles among a pain-free population when moving from an upright to a slump sitting posture. SUMMARY OF BACKGROUND DATA The presence of the flexion relaxation phenomenon (FRP) of the back muscles is well documented at end-range spinal flexion when...
متن کاملLoad and speed effects on the cervical flexion relaxation phenomenon
BACKGROUND The flexion relaxation phenomenon (FRP) represents a well-studied neuromuscular response that occurs in the lumbar and cervical spine. However, the cervical spine FRP has not been investigated extensively, and the speed of movement and loading effects remains to be characterized. The objectives of the present study were to evaluate the influence of load and speed on cervical FRP elec...
