Brief Summary

Background: One treatment of Muscle trigger points (MTrPs) is deep dry needling (DN) with the purpose of obtaining local twitch responses (LTRs), which are highly effective in releasing MTrPs. In DN procedures the mechanisms associated with LTRs and the LTR intensities required for optimal clinical results are poorly understood, especially in relation to range of motion after intervention. Therefore, evaluating the intensity of LTRs is relevant for implementing DN in different clinical settings, such as in patients with muscular or neurological dysfunctions. One way to assess muscle contractions and LTRs is through ultrasound video analysis. The aim of this report was to evaluate the reliability of semi-automatic LTR intensities tracking during dry needling by assessing ultrasound signals with an image processing method, in addition to evaluating the relationship between LTR intensities and muscle elasticity. Method: Young males without signs or symptoms of musculoskeletal pain were included. Primary outcome measure was the LTR intensities determined by percentage change of muscle thickness. The secondary outcome measures were the muscle elasticity of medial gastrocnemius and hamstring, previous and posterior DN in both lower limbs for each subject. Three LTRs, detected by a physical therapist and ultrasound assessment, were induced by inserting a filament needle into muscle latent trigger points in medial gastrocnemius. The intensities of LTRs were measured by assessing ultrasound images using an optical flow method and through comparisons with manual detection.

Study Arms (1)

Deep Dry Needling

EXPERIMENTAL

Deep Dry Needling (DN) with the purpose of obtaining local twitch responses (LTRs). Description: Latent MTrPs were identified in both MG using according the presence of a palpable taut band and hypersensitive spot in the palpable taut band as diagnostic criteria. The deep DN was administered by a physical therapist with three years of experience in the technique. The ultrasound video (SonoSite Titan; Sonosite, Bothell, WA, USA) was recorded at 60 frames per second captured through an external capture device from Epiphan Systems Inc. (Ottawa, Ontario, Canada). According to the perception of the physical therapist and the ultrasound assessment, the filament needle was inserted into the MTrP to achieve three LTRs. Posterior to DN application, the ROMs of the MG and HA were measured
