TL;DR: The modified Thomas test was used to determine the range of flexibility of 117 elite athletes in tennis, basketball, rowing, and running to provide objective data for a clinical test measuring flexibility of the iliopsoas, quadriceps, and tensor fascia lata/iliotibial band.
Abstract: AIM: To analyse the modified Thomas test and obtain measures of flexibility for the iliopsoas, quadriceps and tensor fascia lata/iliotibial band. METHOD: The modified Thomas test was used to determine the range of flexibility of 117 elite athletes in tennis, basketball, rowing, and running. RESULTS AND CONCLUSION: The study has provided objective data for a clinical test measuring flexibility of the iliopsoas, quadriceps, and tensor fascia lata/iliotibial band. It is recommended that sufficient flexibility is obtained to perform a specific sport and that asymmetries between limbs are addressed.
TL;DR: The high correlations obtained in this study suggest that the inclinometer and the goniometer are reliable instruments for measuring hip extension flexibility and indicate that the two instruments can be used interchangeably for measuring hips extension flexibility.
Abstract: Our objectives were to examine interrater reliability for inclinometer and goniometric measurements of hip extension flexibility and the intra- and interrater reliability between instruments when measuring hip extension flexibility with the modified Thomas test. The modified Thomas test is frequently used by clinicians to assess hip extension flexibility. Studies examining the reliability of measures of the modified Thomas test are limited. This study included 42 healthy subjects. The modified Thomas test was performed on each subject to quantify hip extension flexibility by using an inclinometer and a goniometer. High interrater reliability was determined for each instrument (r = 0.91-0.93; ICC = 0.89-0.92). High intrarater parallel-forms reliability was found for each examiner between the instruments (r = 0.089-0.92; ICC = 0.91-0.93). High interrater parallel-forms reliability also was found between instruments (r = 0.86-0.93; ICC = 0.86-0.92). The high correlations obtained in this study suggest that the inclinometer and the goniometer are reliable instruments for measuring hip extension flexibility. The results also indicate that the two instruments can be used interchangeably for measuring hip extension flexibility.
TL;DR: Clinicians can be 95% confident that an observed change between 2 measures larger than 3.0° likely indicates a real change in muscle flexibility.
TL;DR: Results call into question the statistical reliability of the Thomas test, but provide clinicians with important information regarding the reliability limits of this orthopaedic technique when used to clinically evaluate hip range of motion and ilio-psoas muscle flexibility in a physically active population.
TL;DR: In this paper, the reliability characteristics of four positioning techniques used to measure hip extension (prone hip extension, Thomas, Mundale, and pelvifemoral angle) were compared and the least reliable readings in the cerebral palsy group were found from tests using the Thomas technique, and in the meningomyelocele group using the Mundale technique.
