“…Likewise, just like MM, functional tests, such as the sit-andreach or weight-bearing lunge tests, are usual tools to assess the effectiveness of FR on ROM (Sullivan et al, 2013;Halperin et al, 2014;Grieve et al, 2015;Peacock et al, 2015;Škarabot et al, 2015;Kelly and Beardsley, 2016;Patel et al, 2016;Boguszewski et al, 2017;Grabow et al, 2017;Jung et al, 2017;Paz et al, 2017;Sagiroglu, 2017;Garcia-Gutiérrez et al, 2018;Phillips et al, 2018;Guillot et al, 2019;Pathania and Muragod, 2019;Somers et al, 2019;Williams and Selkow, 2019; Table 6). Other clinical examinations, such as the Thomas test or the straight leg raise test, are also regularly used to quantify flexibility with manual or electric goniometers after FR (MacDonald et al, 2014;Mohr et al, 2014;Cho et al, 2015;Su et al, 2017;Do et al, 2018;Killen et al, 2018;Madoni et al, 2018;Guillot et al, 2019;Jeong et al, 2019;Kyranoudis et al, 2019;Lim and Park, 2019;Oranchuk et al, 2019; Table 6). Applied to FR research, goniometer/inclinometer index gains in terms of degrees of freedom of the joints (Peacock et al, 2015;Škarabot et al, 2015;Fairall et al, 2017;Le Gal et al, 2018; Table 6…”
