M: mean, SD: standard deviation, and unit: degree.

HRA: head repositioning accuracy, NF: neck flexion, NE: neck extension, NRSF: neck right side flexion, NLSF: neck left side flexion, NRR: neck right rotation, NLR: neck left rotation, STA: shoulder tilting angle, PAT: pelvic anterior tilting, PSTA: pelvic side tilting angle, and ScL: scapular level.
