OBJECTIVES: This study compared soft versus hard resting hand splints on pain and hand function in 39 persons with rheumatoid arthritis. Splint preference was also evaluated to determine its effects on splint wear compliance. METHOD: A repeated measures research design was used to compare the two experimental conditions, wearing a soft splint versus a hard splint on the dominant hand for 28 days at night only, and an unsplinted control period of 28 days. RESULTS: Arthritis pain was considerably less during both splinted periods when compared with the pretest. Subjects identified fewer joints as being painful during the soft splint condition than during the unsplinted condition. There were no significant differences among conditions on hand function measures. Splint preference was 57% for the soft splint, 33% for the hard splint, and 10% for no splint. Splint wear compliance was significantly better with the soft splint (82%) than with the hard splint (67%). CONCLUSION: The findings indicate that resting hand splints are effective for pain relief and that persons with rheumatoid arthritis are more likely to prefer and comply with soft splint use for this purpose. Individualized splint prescription that focuses on client comfort and preference may enhance splint wear compliance.
The purpose of this study was to compare the objective, subjective, and radiographic responses of patients with carpometacarpal joint osteoarthritis (CMCJ-OA) wearing a prefabricated neoprene splint (PFN), which crosses the CMCJ and metacarpophalangeal joint, with those of patients wearing a custom-made thermoplastic short opponens splint (CMT), which crosses only the CMCJ. Patients ( N = 25) with first CMCJ stage I and II osteoarthritis were assigned randomly to wear either the PFN splint or the CMT splint for one week. After one week, the subjects rated their function in the splint and their satisfaction and pain levels on visual analogue scales. Pinch measurements were performed and x-rays were taken to assess carpometacarpal subluxation. The second splint was then applied for one week and all measures were repeated. The subjects rated the PFN splint significantly higher, and most reported that they would choose the PFN splint over the CMT splint for daily and long-term use. Both pain and function were improved with splinting, but the effect was amplified with the PFN splint compared with the CMT splint. Both splints reduced subluxation at the first carpometacarpal joint, but the CMT effect was greater. This study further supports current evidence that subjects with stage I and II first CMCJ-OA will have pain relief with thumb splinting. In addition, the PFN splint will provide greater relief when compared with the CMT splint. Furthermore, this study reveals that patients prefer the PFN splint to the CMT splint.
Predisposing factors contributing to the development of first carpometacarpal (CMC) osteoarthritis include an inherent laxity or incongruency of this joint, a shallow trapezium saddle, and heavy stresses placed on the joint with pinching and grasping. Splinting is a common mode of conservative treatment for CMC osteoarthritis. This study assessed the objective and subjective responses of patients with CMC osteoarthritis who wore short and long opponens splints, as well as radiographic changes associated with wearing of the splints. The study evaluated 26 hands. Each patient was assigned at random to wear the long or the short splint first. Patients wore the splints for one week. They then documented function in their splints (on 22 activities of daily living) and rated splint satisfaction and pain levels on visual analog scales. One week after application of the first splint, the second splint was applied and worn for one week, and all measures were repeated. On the final visit, tip pinches were evaluated and x-rays were taken to assess subluxation. One-way repeated-measure analysis and paired comparison were used to analyze the pinch, pain, radiographic, and splint-rating measures. Descriptive statistics were used to assess activity-of-daily-living function and splint preference. Both splints appear to reduce subluxation at the first CMC joint in patients with grades 1 and 2 osteoarthritis. The majority of the patients picked the short splint when asked at the end of the study which splint they preferred. The splints do not appear to increase pinch strength or affect pain levels associated with the performance of pinch strength measurements. This study supports anecdotal evidence that patients with CMC osteoarthritis get pain relief with splinting.
