In this study, we attempted to evaluate whether the levels of thyroid stimulating hormone (TSH), free thyroxine (fT4), and free triiodothyronine (fT3), as well as serum levels of anti-thyroglobulin antibodies (aTG) and anti-thyroid peroxidase antibodies (aTPO), affect hand grip strength (HGS) in patients with thyroid-corrected TS. This evidence concerns the gene TPO and thyroid gland disorder.
