The purpose of this study was to investigate whether the application of deep trigger point dry needling (TDN) to latent trigger points within the gluteus medius musculature affected strength measurements of the gluteus medius immediately following intervention. A control and an intervention side were randomly assigned for each participant (N = 39). Hand held dynamometer (HHD) force measurements and surface electromyography (sEMG) amplitude readings were recorded during maximal volitional isometric contraction break tests of the gluteus medius in two separate positions (SL0 and SLIR) both before and after application of TDN. Comparison of within and between group data were conducted. A statistically significant interaction between time (pre-TDN to post-TDN) and groups (intervention side and control side), p < .001 was found for HHD measurements in both positions. Post hoc analysis revealed a statistically significant difference (p < .001) for all comparisons in the SL0 position, while, for the SLIR position, statistically significant differences (p < .001) were found for pre and post-TDN measurements within intervention side as well as between the intervention and control side for post-TDN measurements. For sEMG amplitude measurements, statistically significant differences were found only in the SL0 position for within group comparisons on the intervention side (p = .009) as well as for between group comparisons for post-TDN measurements (p = .002). Application of deep TDN to latent trigger points within the gluteus medius can significantly increase gluteus muscle force production immediately following intervention while reducing the level of muscle activation required during contraction.
