# Pharmacologically Induced Accommodation Palsy and the Bioelectrical Activity of the Muscular System: A Preliminary Investigation

## TL;DR

This study explores how inducing eye accommodation paralysis affects muscle electrical activity in people with myopia and normal vision.

## Contribution

The study introduces a novel approach to investigate the relationship between pharmacologically induced accommodation palsy and muscular bioelectrical activity.

## Key findings

- Electromyographic assessments were conducted on multiple muscle groups after inducing accommodation palsy.
- No definitive clinical significance was established for the observed effects.
- Further research is recommended to validate the findings.

## Abstract

The aim of this study was to pharmacologically induce accommodative paralysis and evaluate its effects on the bioelectrical activity of the muscular system. The study included two participant groups: those with myopia and those with normal vision (emmetropes). Electromyographic assessments were performed using the Noraxon Ultium DTS 8-K MR 3 myo Muscle Master Edition system. The muscles analyzed in this study were the temporalis, masseter, sternocleidomastoid, trapezius, abdominal muscles, biceps brachii, and the external oblique muscles of the abdomen. It is important to acknowledge that, based on the current findings, it cannot be definitively stated that the observed effects have clinical significance, and additional studies are encouraged.
