    BackgroundFew studies have investigated the dry needling (DN) approach on knee osteoarthritis (KO) patients. The study's aim was to evaluate the short-term efficacy of adding DN to a therapeutic exercise protocol in the treatment of KO in older adults.MethodsA double-blind, pilot clinical trial with parallel groups [NCT02698072] was carried out for 12 weeks of treatment and follow-up. Twenty patients aged 65 years and older with myofascial trigger points (MTrPs) in the muscles of the thigh were recruited from older-adult care centers and randomly assigned to a DN + Exercise group or a Sham-DN + Exercise group. The Numeric Rating Scale (NRS; primary outcome) and Western Ontario and McMaster Universities Osteoarthritis Index questionnaire (WOMAC) were assessed before and after the intervention.ResultsThe NRS (analysis of variance, ANOVA) showed statistically significant differences in the time factor (F = 53.038; P < .0001; ηp = 0.747). However, it did not show a significant change in the group-time interaction (F = 0.082; P = .777; ηp = 0.005). The WOMAC scores (ANOVA) showed statistically significant differences in the time factor for total score WOMAC questionnaire (F = 84.826; P < .0001; ηp = 0.825), WOMAC pain (F = 90.478; P < .0001; ηp = 0.834), WOMAC stiffness (F = 14.556; P < .001; ηp = 0.447), and WOMAC function (F = 70.872; P < .0001; ηp = 0.797). However, it did not show a statistically significant change in the group-time interaction.ConclusionDespite the pain intensity and disability clinically relevant improvement for both DN and Sham-DN combined with exercise, 6 sessions of DN added to a therapeutic exercise program for older adults with KO did not seem to improve pain intensity and functionality.
