Latent Myofascial Trigger Points Are Associated With an Increased Intramuscular Electromyographic Activity During Synergistic Muscle Activation

The aim of this observational study was to measure both intramuscular and surface electromyographic (EMG) activity of latent neuro-trigger points (LNTP) compared to non-LNTP in the upper trapezius (UT) during shoulder abduction in asymptomatic subjects. The investigators recorded intramuscular EMG activity of the UT and surface EMG recordings for the middle deltoid, and upper, middle, […]
