Relationship between limb movement speed and associated contraction of the trunk muscles

Article Abstract:

Researchers investigated the response of trunk muscles to differing speeds of movement of the shoulders. Contraction of trunk muscles precedes shoulder movement and is part of the posture and spine stabilization mechanism. Subject performed shoulder flexions at varying speeds and the researchers used electrodes to measure the onset of EMG in the different trunk muscles. They found that speed of movement of the limbs influenced the reaction time of trunk muscle contraction only at slow speeds, when it was considerably slower than in the other two modes.

Evaluation of impact loading in overhead work using a bolt pistol support

Article Abstract:

A study was conducted to analyze the effect of a bolt pistol support on impact loading of the hand-arm system in the process of firing spiked bolts into a steel beam. The study tested 10 male volunteers who fired the bolts with and without the support. Results show that acceleration peak values were reduced during firing with the bolt gun support. Damping effect was felt at the thumb and elbow bones.

Effectiveness of overhead lifting devices in reducing the risk of injury to care staff in extended care facilities

Article Abstract:

The effectiveness of an overheard ceiling lift programme at reducing the risk of injury from resident handling was evaluated by comparing injury data and staff perceptions before and after implementation of the programme. A significant reduction was observed in the perceived risk of injury and discomfort to the neck, shoulders, back, hands, and arms of care staff.
