A quasi-experimental trial. Orthoses are effective to
decrease pain and improve function in patients with carpometacarpal
osteoarthritis (CMC OA). However, current research does not support one design of
an orthosis as more effective and/or more favorable than another.
The aim of this study was to compare the effectiveness of 2 different
static orthosis on pain and functional abilities on CMC OA. METHODS: Eighty-four
patients, 91.7% females (mean +/- standard deviation age, 60.1 +/- 9.6 years),
with thumb CMC OA were randomized into 1 of 2 groups. For group A, a Ballena
orthotic was constructed, and for group B, a Colditz orthotic was constructed.
Both static orthoses were worn for 3 months. The outcome measures included pain
with activity measured with the visual analog scale and functional abilities
assessed with the Disabilities of the Arm, Shoulder and Hand. RESULTS: Both
orthoses improved pain level and functional abilities (F[1.0] = 413.327 and
F[1.0] = 211.742; both P < .001). There was no statistically significant
difference between 2 groups regarding to pain recovery and functional improvement
(F[1.0] = 0.075 and F[1.0] = 7.248; both P > .05). DISCUSSION: The main purpose
was to compare the effect of 2 different thermoplastic thumb orthoses. Previous
studies support the use of CMC orthoses to decrease hand pain and improve hand
function, but different orthoses have been described and in most cases, orthotic
interventions were accompanied by other medical treatments. CONCLUSIONS: A
clinically significant reduction in pain intensity and improvement in functional
abilities was achieved with both orthoses in patients with thumb CMC OA. LEVEL OF
EVIDENCE: 2. TRIAL REGISTRATION: ClinicalTrials.gov registration number:
NCT02780999.
