Efectividad del entrenamiento propioceptivo en la recuperación funcional de la artrosis en la base del pulgar. Ensayo clínico multicéntrico con aleatorización simple no cegado

Abstract

Background and objectives

Osteoarthritis at the base of the thumb (CMC-1 OA) is a pathology that mainly affects postmenopausal women. The main symptoms including pain, decreased hand-thumb strength and fine motor capacity. Although a proprioceptive deficit has already been demonstrated in people with CMC-1 OA, there is insufficient evidence regarding the effects of proprioceptive training. The main objective of this study is to determine the effectiveness of proprioceptive training in functional recovery.

Materials and methods

A total of 57 patients were included in the study, 29 in the control group and 28 in the experimental group. Both groups underwent the same basic intervention programme, but the experimental group included a proprioceptive training protocol. Variables of the study were pain (VAS), perception of occupational performance (COMP), sense position (SP) and force sensation (FS).

Results

Statistically significant improvement was observed in the experimental group in pain (p < .05) and occupational performance (p < .001) after 3 months of treatment. No statistical differences were found in sense position (SP) or sensation of force (FS).

Discussion and conclusions

The results concord with previous studies focussing on proprioception training. The incorporation of a proprioceptive exercise protocol reduces pain and significantly improves occupational performance.
