Ergonomic hand tool design.
The use of ergonomic design and appropriate selection of hand tools can reduce exposure to cumulative trauma. The design and principles presented in this article should help reduce the biomechanical stresses to the workers' hands, arms, and shoulders. Remember, tissues of each individual have a threshold of resistance, and if that threshold is crossed too many times by a defective or ill-fitting tool, pathologic changes can occur. The proper tool design, rotating work schedules, work pacing, scheduling, and exercise programs can, in combination, improve productivity and promote human wellness.
