This study compared the proposed modified sit and reach test (MSR) and the commonly administered sit and reach test (SR) to determine if the MSR can administratively control possible limb-length biases. Subjects (N=258) were administered two trials of each test. The MSR test incorporates a finger-to-box distance (FBD) to account for proportional differences between legs and arms. Individuals with high FBD measurements demonstrated a poorer performance on the SR test. An analysis of the subjects failing to meet the Physical Best standard (25 cm) indicated a higher probability of failure for those with larger FBD scores. The subjects were subsequently separated into three groups: high, medium, and low FBD. There were no significant difference among the groups on MSR performance but a significant difference was found on SR performance. The MSR test appears to eliminate the concern of disproportionate limb-length bias expressed by many practitioners.
