RISK FACTORS: KEYBOARDING, CLERICAL WORK
In the absence of reliable evidence, it is the opinion of the workgroup that there is no association between high keyboard use and carpal tunnel syndrome.

Rationale

No high- or moderate-quality studies were identified to address the question of the association of keyboard use and carpal tunnel syndrome. A single low-quality study that met inclusion criteria, (Eleftheriou et al. 2012), reported a statistically significant association between high keyboard use and carpal tunnel syndrome.

Benefits/Harms of Implementation
This recommendation is based upon a research question that was specifically focused on the association of high keyboard use and carpal tunnel syndrome. The potential harm in the CPG lies in the lack of recognition of keyboard use as a strong risk factor or causative variable for carpal tunnel syndrome which has implications for worker’s compensation cases and physicians called upon to evaluate causation.
