The reliable quantitative measurement of TPA power was not established. The purpose of this study was to report on the reliability of TPA strength measurements by the hand-held dynamometry (HHD) in large samples of CTS and its superiority over other tests, including grip, pinch powers, TPA angles and manual muscle testing, in terms of clinical progress indicators. <\/jats:p><jats:p> Methods: We examined the relative and absolute reliabilities of the perioperative TPA strength measured by HHD (HHD-TPA) in 566 participants with CTS and the correlation coefficient between the HHD-TPA and other clinical tests. <\/jats:p><jats:p> Results: The reliability of the HHD-TPA was intraclass correlation coefficients: 97% or higher. The Bland\u2013Altman absolute reliability showed a random pattern of bias, and the minimal detectable changes (MDC) of the inter-rater and intra-rater reliabilities indicated 9.0 N and 7.0 N individually. The HHD-TPA showed statistically significant recoveries between perioperative stages; however, the mean difference larger than the MDC was recognised only between the preoperative and 12-month postoperative stages by intra-rater comparison. More individual patients showed recovery of HHD-TPA beyond the MDC when the same examiner continuously measured HHD-TPA than when multiple examiners continuously measured HHD-TPA. Grip strength and pinch strength measurements showed a strong correlation with HHD-TPA and did not show statistically significant improvement during the perioperative period. <\/jats:p><jats:p> Conclusions: HHD-TPA is the most reliable method for quantifying muscle strength in the perioperative course of TPA force in CTS. HHD-TPA is a more reliable assessment of CTS motor recovery when measured consistently for each patient by the same hand therapist. <\/jats:p><jats:p> Level of Evidence: Level IV (Diagnostic)
