Abstract

A survey of those features of hand tools relevant to the physical interaction between the implement and the human operator. Concepts basics to the optimization of forces are mentioned, followed by a description of some of the more common physiological problems and musculoskeletal complaints associated with improper hand tool and design and usage. An account of the distribution of contact pressures and possible consequences, if these are excessive, is followed by a description of the role of working gloves as related to ergonomic problems and their possible relationships to occupational diseases of the hand and wrist. Some aspects of anatomy and anthropometry pertinent to the optimization of posture, motion patterns and tool size precede a list of desirable features for power tools. A glossary is included as an aid to the reader. The concepts and situations described are applicable to the design and use of the vast majority of hand tools.

[Can the carpal tunnel syndrome be work-related?].

The carpal tunnel syndrome is the most commonly reported nerve entrapment syndrome. While a number of medical risk factors are wellknown, accounting for approximately 25% af the cases, the significance of repetitive occupational hand strain has been disputed during several decades. Recently, a number of controlled epidemiological studies concerning this issue have emerged. A critical review arrives at the conclusion that jobs requiring highly repetitive and forceful sustained hand activity are associated with an increased risk for the carpal tunnel syndrome. The risk is, in particular, high when both risk factors are involved concomitantly. Exposure to hand-arm vibration also increases the risk, but it is undecided whether vibration per se or the associated ergonomic strain is the causal factor. It is argued that the evidence is sufficient to justify worker compensation and action should be taken to prevent this work-related disorder.

[Carpal tunnel syndrome. The most frequent pressure-induced peripheral nerve lesion].

Carpal tunnel syndrome is the term given to compression neuropathy of the median nerve in the carpal tunnel. It is the most common pressure-induced peripheral nerve lesion. It is typically associated with numbness of the index, long and ring fingers, and nocturnal brachialgia. The diagnosis is supported by the typical clinical symptomatology and the positive Hoffmann-Tinel sign, and is confirmed by the electroneurographic examination (ENG) of the median nerve, which can also be used for follow-up monitoring. During surgery, careful inspection and palpation of the carpal tunnel must be performed to detect such conditions as synovitis, anatomical variants and tumors.
