Comparison of Muscular Activities in Patients with Covid19 and Healthy Control Individuals during Gait

The aim of the present study was to compare the frequency spectrum of lower limb muscles in patients with Covid-19 and healthy control individuals during gait.

The statistical sample of the present study included 15 patients with Covid-19 (age: 24.6± 9.1) and 15 healthy individuals (age: 23.2 ±8.0) who were selected using convenience sampling. The electrical activity of selected lower limb muscles was recorded using electromyography system during gait. Independent sample t-test was used for statistical analysis.

During loading response phase, the frequency spectrum in the vastus medialis, vastus lateralis, and gluteus medius muscles were significantly greater in the patient group than those in the healthy group (p < 0.05). During mid-stance phase, all of the selected muscles showed a similar median frequency values in the two groups (P>0.05).

Lowering the functional capacity of the lower limb muscles results in a lack of proper control of the ground reaction forces, which could increase the likelihood of injury and falls in patients.
