RESUMO
STUDY DESIGN: Randomized, interventional trial with 1 year follow-up. INTRODUCTION: Though recommended, evidence is lacking to support specific exercises to stabilize and strengthen the first carpometacarpal (CMC) joint for cases of osteoarthritis (OA). PURPOSE OF THE STUDY: To determine in a naturalistic setting, whether standard treatment plus a home exercise program (ST+HEP) is more effective than standard treatment (ST) alone in improving Quick Disabilities of Arm, Shoulder and Hand (qDASH) scores, and secondarily, in other patient-centered (pain, function) and clinical outcomes (range of motion, strength). METHODS: A total of 190 patients from a hand therapy practice in northwestern PA were enrolled by informed consent and randomized into ST or ST+HEP groups. Average age was 60 years, most were female (78%) with sedentary occupations most common (36%). ST group received orthotic interventions, modalities, joint protection education and adaptive equipment recommendations, while the ST+HEP group received a home exercise program in addition to ST for 6-12 months. Follow-up occurred at 3, 6, and 12 months. Outcomes included grip strength, pinch strength, range of motion (ROM), qDASH, Patient Specific Functional Scale (PSFS) and pain ratings. At the 6 month mark, all subjects could change groups if desired. Efficacy data analysis included both parametric and non-parametric tests. The threshold for statistical significance was 0.05 and adjusted for multiple comparisons. RESULTS: Repeated measures ANOVA failed to show a statistically significant difference in strength and ROM assessments between treatment groups over the 12 month follow-up (P ≥ .398). Differences between groups did not exceed 13%. Both the ST and ST+HEP groups evidenced improvement over time in most patient-focused assessments (P ≤ .011), including improvements exceeding reported clinically important differences in pain with activity and PSFS scores. Scores for these measures were similar at each follow-up period (P ≥ .080) in each group. The presence of CTS exerted no effect on outcomes; longer treatment time was weakly related to poorer qDASH and PSFS scores initially. Of those enrolled, 48% of subjects completed the study. CONCLUSIONS: The addition of a high-frequency home exercise program did not improve clinical or patient-centered outcomes more so than standard care in our sample however, study limitations are numerous. Both groups had decreased pain with activity and improved PSFS scores, meeting the established minimally clinically important difference (MCID) of each at 6 and 12 months. Adherence with the home program was poor and/or unknown.
RESUMO
BACKGROUND: There are a variety of postoperative immobilization and therapy options for patients with basal joint arthritis. Although prior systematic reviews have compared surgical procedures used to treat basal joint arthritis, none to our knowledge compares therapy protocols for this condition, which are considered an important part of the treatment. QUESTIONS/PURPOSES: (1) We sought to determine whether differences in the length and type of postoperative immobilization affect clinical results after basal joint arthritis surgery. (2) We also compared specific therapy protocols that were prescribed. (3) Finally, we evaluated published protocols to determine when patients were released to full activity to see whether these appeared to affect clinical results. METHODS: A systematic review of English-language studies in the PubMed and Cochrane databases was performed. Studies were then reviewed to determine what postoperative immobilization and therapy protocols the authors used and when patients were released to full activities. A total of 19 studies were identified using the search criteria. RESULTS: All but one of the studies included a postoperative period of immobilization in either a cast or splint. Immobilization time varied depending on whether Kirschner wires were used for the surgery and whether an implant was placed. Postoperative therapy protocols also varied but followed three general patterns. Some therapy protocols involved teaching patients a home exercise program only, whereas some authors described routine referral to a therapist. The third group consisted of studies in which patients were only referred for therapy if the physicians determined it was necessary during followup. Many studies did not give a specific time for full return to activity and instead described a gradual transition to full activity after immobilization was discontinued. Because of the variability and small numbers, no conclusive recommendations could be made on any of the three study questions. CONCLUSIONS: Comparative, multicenter studies comparing different immobilization and therapy protocols after the surgical treatment of basal joint arthritis would be helpful for both surgeons and therapists looking to refine their treatment protocols.
