Prediction of forearm muscle activity during gripping

Article Abstract:

A set of equations was developed and validated to predict forearm muscle activity from grip force and posture of the wrist and forearm. Detailed error analysis during validation revealed that inclusion of posture in the model effectively decreased error at grip forces above 25% maximum, but was detrimental at very low grip forces. The study presents a potential new tool to estimate forearm muscle loading in the workplace using grip force and posture, as a surrogate to use of a complex biomechanical model.

The development and validation of equations to predict grip force in the work place: Contributions of muscle activity and posture

Article Abstract:

The measuring forces in ergonomics workplace led to the need for equations to predict grip force, where a family of equation was developed, and validated by using forearm electromyography and inclusion of muscle activity. The study presents an educated decision to be made on which muscles to monitor depending on expected force levels, costs and error deemed acceptable by the potential user.

The effects of posture on forearm muscle loading during gripping

Article Abstract:

An attempt made to quantify the response of the forearm musculature to combinations of wrist and fore arm posture and grip force, is presented. Rotation of the forearm, wrist was measured along with electromyography (EMG) amplitude for both the genders.
