Enter information in left column (first section); select appropriate

back flexibility for adults.
After a brief warm up the subject sits on floor with shoes
off. Subject places bottom of feet (10 to 12 inches apart) against
side of box (approximately 12" or 30 cm high) with knees
straight. Tester places measuring stick on box parallel to subjects
legs; 15" or 38 cm at edge of box closest to subject and
end of measuring stick ("0") toward subject. Subject
places hand over hand and reaches as far as possible over measuring
stick without bending knees. Best of three tries is recorded.
The quality of the stretch should also be examined for smoothness
of spinal curve and the angle of hip (near 90° or more).
