Comparison of custom-made and prefabricated neoprene splinting In patients with the first carpometacarpal joint osteoarthritis

Aim: The objective of this study was to compare the effect of prefabricated and custom made thumb splints on pain, function, grip strength and key pinch In patients with basilar joint osteoarthritis. Method: Volunteer patients (n = 35) with first carpometacarpal joint osteoarthritis were assigned randomly to wear either a prefabricated or custom-made thumb splint or assigned to a control group. This was designed as a cross over study with two 4-week treatment periods, 2 weeks of wash out time for intervention groups between the test conditions and 10-weeks follow-up for the control group. All parameters were measured at the first visit and during the 4th, 6th and 10th weeks In the three groups. Results: In the control group, paIn increased and pinch strength decreased but no statistically significant differences were found In function and grip strength. Both splints changed grip strength with no significant differences between them. PaIn was reduced with the splints, and functions and pinch strength increased significantly as compared to the baseline and control groups. In comparing the two splints only significant differences were observed In pain. Conclusion: In comparing two splints, paIn was the only significantly different parameter between tested parameters; with the custom-made splints demonstrating better results In paIn reduction.

Implications for Rehabilitation

• A high level of disability has been reported In those patients with thumb carpometacarpal joint osteoarthritis.

• Custom-made and prefabricated neoprene splinting is an effective method to improve pain, pinch strength and function by patients with the first carpometacarpal joint osteoarthritis.

• The custom made splint demonstrated better results In paIn reduction.
