Impact of Verbal Suggestions on Finger Flexor Activation and Strength in Healthy Individuals.

ABSTRACT: BACKGROUND Words uttered by other people can have an enormous influence on how we perceive our surroundings, what we expect, what we experience, and how we behave. This study aimed to evaluate the effect of verbal reinforcement on the placebo effect in the context of finger flexor muscle activation measured with surface electromyography (sEMG) and hand grip strength measured with a hand dynamometer in healthy subjects. MATERIAL AND METHODS Eighty-eight individuals aged 22.64±5.2 years took part in the study. For each person, paper tape was applied (placebo). The participants were randomly assigned to 1 of the 3 groups: positive information group (P) - "the tape increases hand muscle strength", negative information group (N) - "the tape decreases hand muscle strength", and control group (C)
