In some cases, exercise is an effective treatment for many chronic conditions.

Exposures to vibratory tools tended to be relatively prolonged and intense. A case-control study of surgically-treated CTS found a more than doubling of risk from work with hand-held vibratory tools, but with exposure durations defined very broadly between 1 and 20 years [ 60 ], and a second reported a RR of 3.

Excess risks were also reported In food processing and food packing — in poultry workers OR 2. Many of these occupations involve prolonged or repeated flexion and extension of the wrist, and in keeping, assessments of risk by main activity Table 6 find higher risks with these exposures.

Four studies [ 53Carpal tunnel syndrome thesis5960 ] found that repeated flexion and extension of the wrist increased the risk of physician-confirmed CTS. Three studies pointed to wrist flexion or extension for at least half of the working day as carrying a notably high risk.

The most telling evidence on force and repetition comes, however, from a well-known and careful survey by Silverstein et al [ 21 ], which videotaped workers from 7 different industries.

Use of the computer keyboard and mouse have also been closely studied, but with far less evidence of elevated risk. Other surveys have also proved generally reassuring [ 5761 ].

The studies mentioned here are not without individual limitations. In particular, almost all collected information about exposures retrospectively, with potential for information bias.

Some studies were small and some may not have fully controlled for confounding. Conceivably, a few investigations were prompted by workplace clusters, which would lead to unrepresentatively high estimates of risk.

Notwithstanding these problems, the body of evidence as a whole is consistent, and the stronger studies, including those that undertook direct assessments of exposure rather than relying on self-report, point in the same direction [ 31 ].

Finally, from a biomechanical viewpoint, the findings are plausible. It can be demonstrated experimentally, in human cadavers and animal models, that extreme flexion and extreme extension of the wrist increase the pressure in the carpal tunnel sufficiently to impair blood perfusion of the median nerve [ 6263 ], so that epidemiological and physiological investigations offer a coherent view of causation.

Compensation and statutory reporting In many countries industrial diseases are compensated by state welfare benefit for workers who develop illness because of their occupation. In Britain, for example, provisions have existed to cover occupational accidents since and occupationally-related diseases since However, only willing, knowledgeable and insured workers employees rather than the self-employed can lodge a claim, and benefit is only paid under qualifying conditions of occupation and severity.

Altogether, the Department for Works and Pensions confirms only about a few hundred cases per year from these causes, most likely the tip of a morbidity iceberg.

In many countries there is also a legal duty to report a scheduled list of work-related illnesses to health and safety enforcement agencies. In Britain, most of the illnesses which are compensable by the State, including CTS, must be notified to the Health and Safety Executive or to local Environmental Health Officers when they occur in qualifying circumstances of exposure.

The onus falls on informed employers to submit a return, and under-reporting is recognised to be a wide-spread and significant problem.

Case management and prevention The management of work-associated CTS is similar to that of non-occupational CTS, with the important exception of advice on control of causal or aggravating exposures. Conservative measures may suffice.

Electrophysiological evidence of nerve entrapment is generally sought before proceeding to the ultimate step of surgical release, which is usually effective. Ahead of this, measures to mitigate workplace exposures, temporarily hand-wrist repetition or permanently hand-transmitted vibrationmay be appropriate.

Preventive measures, based on an assumed mechanical pathogenesis, may include: Box 1 summarises some principles of good ergonomic practice drawn from general principles. Prevention by following good ergonomic principles [ 67 ] Physical risk factors in industry include: Assuming a precautionary line, highly repetitive wrist-hand work should be avoided by ergonomic design of tasks and tools, and by appropriate scheduling of work and rest periods.Carpal tunnel syndrome is the compression of the median nerve as it passes into the hand.
