Effectiveness of Trapeziometacarpal Splint

Study Overview
=================
Brief Summary
-----------------
The trapeziometacarpal osteoarthritis is a degenerative or inflammatory joint that affects the trapeziometacarpal joint (TMC) of the thumb. Its main symptom is pain that leads to difficulty in manual function and decrease the patient's quality of life. Immobilization of TMC thumb joint by bracing has been effective in reducing pain and improving function. Objective: To compare the effectiveness between day and night functional splint for patients with trapeziometacarpal osteoarthritis in improving pain and function

Detailed Description
-----------------
Randomized clinical trial, and blind where selected 60 patients diagnosed with trapeziometacarpal osteoarthritis.Os patients were assessed by a blinded evaluator at the beginning of treatment and after 45, 90 and 180 days in relation to pain, thumb range of motion, strength hold, tweezers, dexterity, function and satisfaction.

Conditions
-----------------
Osteoarthritis of Trapeziometacarpal Joint

Intervention / Treatment
-----------------
* Device: Day Splint
* Device: Night Splint


Participation Criteria

Eligibility Criteria
-----------------
Inclusion Criteria: Patients with osteoarthritis in accordance with the American College of Rheumatology classification criteria (ACR); of both genders and age above 18 years; Pain in TMC articulation between 3 and 8 cm in numerical pain scale (END) 10cm Exclusion Criteria: Patients with severe deformities in hand with trapeziometacarpal osteoarthritis not possible to achieve pincer movement between the first, second and third fingers Deformity of the distal interphalangeal joint (IFD) of the thumb Use of splint the thumb in the last six months; Have surgery scheduled on hand for the next six months Allergy to the material of the splint Inability to respond to the questionnaire and perform the tests Geographic inaccessibility Infiltration in hand in the previous 3 months Changes in the use of anti-inflammatory and analgesic past 3 months Physiotherapy in hand over the last 3 months Have the following related diseases: carpal tunnel syndrome, carpal fractures of DeQuervain syndrome, tendonitis, fibromyalgia and chronic inflammatory arthropathy.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Functional Splint group<br>Patient will be using the functional splint during their activity daily life | Device: Day Splint<br>* A thermoplastic splint was confected for each participant to stabilize the trapeziometacarpal joint, maintaining the pulp of the distal phalange of the index finger free for gripping with the other fingers and leaving the thumb in a functional position. In this group the slint was used during the daily life activities.<br>|
| Active Comparator: Night Splint group<br>Patients will use the night splint during the sleep time | Device: Night Splint<br>* A thermoplastic splint was confected for each participant to stabilize the trapeziometacarpal joint, maintaining the pulp of the distal phalange of the index finger free for gripping with the other fingers and leaving the thumb in a functional position. In this group the slint was used during the night.<br>|
