Summary

The aim of this study is to assess the effectiveness of therapeutic modalities (paraffin, ultrasound and orthotics) versus corticosteroid injection for trigger finger.

Detailed description

There are several forms of nonsurgical treatment for trigger finger, the most used are: * Oral nonsteroidal and steroidal antiinflammatory's drugs use to resolve the inflammatory process * Corticosteroids local injection: that proposes to control the inflammation, these injections have shown good effectiveness for trigger finger treatment. * Orthotic: with the aim of to immobilize the affected joint until the resolution of the inflammatory process. * Electrotherapeutic modalities: * Paraffin that increases cellular metabolism and promotes peripheral vasodilatation, favoring the transduction tissue fluid, lymph flow, hyperemia and consequent absorption of exsudato. * LASER -Lower Level Laser Therapy (LLLT): the absorption of light through the skin's photoreceptors stimulates mitochondrial chain reactions, promoting adenosine triphosphate (ATP) synthesis, acting on gene expression, which raises the level of growth factors and Tissue repair Although the non-surgical treatment is often used there is no evidence in the literature of which is the most effective conservative treatment for trigger finger. Thus, it is necessary use appropriate methodology to define the benefits and harms of each treatment modality and assess the effectiveness of these nonsurgical treatments, and may define which one has a higher resolution and lower rates of trigger finger recurrences in short, medium and long term.

Conditions

• Trigger Finger

Interventions

Type	Name	Description
PROCEDURE	Therapeutic modalities: Orthotic (Group 1)	participants will be instructed to remove the orthosis only two hours in the morning, two hours in the afternoon and two hours at night to avoid joint stiffness
PROCEDURE	Therapeutic modalities: LLLT (Group 2)	The LLLT parameters are: * LASER 904nm * P: 1.5W/cm² * 30mV/cm² * Area 2 cm² * 1 Joule por ponto ( in the A1 pulley)
PROCEDURE	Therapeutic modalities: Paraffin (Group 3)	Paraffin will be heated and maintained at 50 ° C. Participants will immerse their affected hand 10 times in heated paraffin, then they will roll up their affected hand in a towel that they will bring, after 20 minutes timed by a trained professional, the subjects will remove the towel and "paraffin glove":
PROCEDURE	Corticosteroid injection (Group 4)	The injection solution is composed of 1 ml of betamethasone and 1 ml of 2% lidocaine.This group may repeat the procedure in two weeks if they report that there was no improvement of the triggering or pain.
