: Quantifying muscle strength is critical in clinical and research settings. A rapid and objective method is ideal. The primary objective of this study was to examine the reliability of a novel device, the rapid objective quantification― tibialis anterior (ROQ‐TA), which quantifies the dorsiflexion force of the tibialis anterior, and to assess its validity against isokinetic dynamometry (IKD). Methods : Ankle dorsiflexion of 20 healthy subjects was assessed by 3 modalities, ROQ‐TA, manual muscle testing, and isokinetic dynamometry, over 2 testing sessions. Results : The intraclass correlation coefficient [ICC (2,1) ] for reliability was 0.872 (0.677–0.949) for the ROQ‐TA and 0.892 (0.728–0.957) for IKD. For validity, the ICC (2,1) values for the ROQ‐TA and IKD were in good agreement, with 0.672 (0.17–0.87) in the first testing session and 0.769 (0.42–0.91) in the second session. Discussion : The ROQ‐TA is a valid and reliable device to test ankle dorsiflexion force in a healthy population. Muscle Nerve , 2018
