Isodynamic evaluation of trunk muscles and low-back pain among workers in a steel factory

Article Abstract:

An isodynamic study of correlation between dynamic parameters of trunk muscle strength and the instances of lower-back pain in 61 workers with and without the history of backache, shows that workers suffering from acute chronic backache have 18-50% less trunk muscle strength than those having incidental backaches and those having no backaches. Predictions of trunk muscle strength were independent of the occupational risk factors. Potential of this method in evaluating trunk muscle strength and its relation with the backache is discussed.

A comparison of forearm and thumb muscle electromyographic responses to the use of laparoscopic instruments with either a finger grasp or a palm grasp

Article Abstract:

Forearm and thumb muscle tension, measured by electromygraphic (EMG) voltage during the use of a laparoscopic grasper held in a finger-in-ring grasp and a palm or pistol grasp, were compared. It was found that the palm grip is more powerful than the finger grip when grasping such instruments, especially at angles perpendicular to the sagittal plane.
