Bilateral Idiopathic Carpal Tunnel Syndrome: Clinical‐Functional Characterization and Efficacy of Two Combined Postoperative Physiotherapeutic Treatments

Abstract

ObjectiveTo evaluate the efficacy of combined association instrument myofascial mobilization (IASTM) and stretching in patients with idiopathic bilateral carpal tunnel syndrome (CTS) operated on one hand and to analyze the response of the operated (OH) and non‐operated (NH) hand according to the sequence of therapies. Research on these parameters has not yet been found in the literature.MethodsRandomized controlled crossover study with 43 participants using the objective and subjective outcome variables. Patients were randomly assigned to two groups: starting with stretching followed by IASTM and starting with IASTM followed by stretching. Then patients underwent surgery on the hand with more severe involvement and physical therapy rehabilitation was started 30 days after for a period of 4 weeks. After the 1‐week interval the participants who started with stretching were referred to IASTM and vice versa, following the same previous patterns. The outpatient reassessments took place at 3 to 6 months. Crossover ANOVA and effect sizes were used as analysis methods.ResultsTime was the most significant outcome for all variables both during therapies and at 6‐month follow‐up. Regarding response to the combined therapies between OH and NH, there were differences for both OH and NH, with the greatest impact on NH for the palmar grip and VAS variables. The treatment sequences were significant for pain on the NH and mental SF‐12, suggesting that starting with IASTM followed by stretching had a superior outcome for these outcomes.ConclusionThe combination of IASTM with stretching, used in the postoperative period of bilateral idiopathic CTS, proved to be supplementary, with significant results and large effect sizes for most of the outcomes assessed, both during the time of application of the therapies and in the 6‐month follow‐up for both hands, and may constitute a viable therapeutic alternative for this population.
