OBJECTIVES: Occupational carpal tunnel syndrome (CTS) due to upper extremity overuse has in recent years been the most commonly recognized occupational disease in the Czech Republic and its prevalence has steadily increased. This pilot observation aimed to assess the effects of exercise techniques and oral enzyme therapy in automotive plant workers with early CTS. PATIENTS AND METHODS: The observation comprised automotive plant assembly line workers in whom nerve conduction study revealed incipient CTS. The subjects were divided into three groups: a group practicing exercise techniques (exercising; N=15), a group receiving oral enzyme therapy (N=16), and a group of controls (N=14). Subjects in the control group were only observed without any specific intervention, which is a common procedure in incipient CTS. Throughout 9-week observation, the workers did their jobs. Prior to and after that period, the workers' CTS-related symptoms were ascertained through structured interviews with a physician and the following median nerve parameters were measured: sensory conduction velocity (SCV) and distal motor latency (DML). RESULTS: In both the exercise and enzyme therapy groups, statistically significant decreases in the total score for symptoms were achieved (p<0.0001), unlike controls. On final examination, both treated groups demonstrated significantly increased SCV as compared with the initial values (p=0.00013 and p<0.0001, respectively); in controls, the mean SCV did not significantly change. Similarly, a statistically significant shortening of DML was noted in the enzyme therapy group (p=0.008). CONCLUSION: The results showed the efficiency of both exercise and oral enzyme therapy in incipient CTS. These methods may be recommended for preventing more severe forms of CTS.
