Input: We included two trials (105 participants) comparing ergonomic versus placebo keyboards. Neither trial assessed the primary outcome (short-term overall improvement) or adverse effects of interventions. In one small trial (25 participants) an ergonomic keyboard significantly reduced pain after 12 weeks (MD -2.40; 95% CI -4.45 to -0.35) but not six weeks (MD -0.20; 95% CI -1.51 to 1.11). In this same study, there was no difference between ergonomic and standard keyboards in hand function at six or 12 weeks or palm-wrist sensory latency at 12 weeks. The second trial (80 participants) reported no significant difference in pain severity after six months when using either of the three ergonomic keyboards versus a standard keyboard. No trials comparing (i) ergonomic positioning or equipment with no treatment, (ii) ergonomic positioning or equipment with another non-surgical treatment, or (iii) different ergonomic positioning or equipment regimes, were found. There is insufficient evidence from randomised controlled trials to determine whether ergonomic positioning or equipment is beneficial or harmful for treating carpal tunnel syndrome.
Output:

This review aimed to find out how effective ergonomic treatments were in treating CTS. Only two studies were found (involving 105 participants). Both were designed to minimise research biases, but neither was of high quality. Neither study assessed short-term overall improvement, adverse effects or need for surgery as outcomes. One small study (25 participants) found an ergonomic keyboard reduced pain after 12 weeks but the second study reported no difference in pain severity between the keyboard groups at six months. Neither study found improvements in hand function or signs of CTS by people using ergonomic computer keyboards more than those experienced by people using standard keyboards. Based on the two studies in this review, which represent all the available evidence of sufficient quality for inclusion, there is no strong evidence for or against the use of ergonomic keyboards for the treatment of CTS.
