Flexion-relaxation response to cyclic lumbar flexion
Clinical Biomechanics, 2004The epidemiology classify cyclic lumbar flexion as a risk factor for the development of cumulative low back disorder. Experimental biomechanical data confirming the epidemiology in humans are lacking. The purpose of this study, therefore, is to investigate the flexion relaxation response to sustained cyclic lumbar flexion in humans.Twelve normal ...

Repeated spinal flexion modulates the flexion–relaxation phenomenon
Clinical Biomechanics, 2003To determine if repeated spinal flexion and loading modulate the deactivation of lumbar muscles near full flexion (flexion-relaxation).Repeated measures experimental study of the effect of repetitive trunk flexion and added mass on the flexion-relaxation phenomenon.Repeated flexion causes muscular fatigue, creep of passive tissues and diminished ...

The authors review the anatomy, surgical technique and the physical factors involved in the restoration of elbow flexion. They conclude that there are distinct mechanical advantages to Clark's method of transfer of muscle from the pectoralis major.

Active elbow flexion is required to position the hand in space, and loss of this function is debilitating. Nerve transfers or nerve grafts to restore elbow flexion may be options when the target muscle is viable, but in delayed reconstruction when the biceps and brachialis are atrophied or damaged, muscle transfer options should be considered.

» Restoration of elbow flexion in the setting of brachial plexopathy is crucial and can be accomplished in a number of ways. Current options include non-free muscle transfers, including tendon, nerve, and pedicled flap transfers, and free functional muscle transfers, most frequently involving transfer of the gracilis muscle.»

Journal of Back and Musculoskeletal Rehabilitation, 2016
BACKGROUND: The flexion-relaxation phenomenon (FRP) in standing is a specific and sensitive diagnostic tool for low back pain. Seated flexion as an alternative could be beneficial for certain populations, yet the behavior of the trunk extensors during seated maximum flexion compared to standing flexion remains unclear.

Flexion–relaxation response to static lumbar flexion in males and females
Clinical Biomechanics, 2003To determine if creep developed in the lumbar viscoelastic tissues during a period of static flexion elicited changes in the muscular responses of the flexion-relaxation phenomenon.Static lumbar flexion is a risk factor in workers, yet the physiological biomechanical and histological processes active in the evolution of the consequent low back disorder

Fixed flexion deformity and flexion after knee arthroplasty.
The Knee, 2003Abstract Fixed flexion deformity and flexion of 284 knee replacements were recorded pre-operatively at 6 weeks and 12 months after surgery. Eighteen knees (6.3%) achieved unsatisfactory movements at 12 months. Seven knees (2.4%) had a fixed flexion greater than 10°, six (2.1%) had flexion less than 90° and five (1.8%) had both.
