The Standing bow (SB) test (reproduced with permission from Movement Performance Solutions). The SB test was used to test the ability to prevent flexion of the lumbar spine during defined movement of the hip in upright standing. The test was classified as a low threshold test. Photos illustrates examples of views during the test. Start position: The subject stood with the pelvis relaxed and lumbar spine in neutral position. Test movement: While keeping the spine straight (not letting it round out or over arch) the subject bent the hips forwards to 50° (forward lean). Criteria: Pass: forward lean with maintenance of lumbar spine in a neutral position.
