NO = Head straight, eyes open, on hard ground; NC = Head straight, eyes closed, on hard ground;
PO,=Head straight, eyes open, on soft ground; PC = Head straight, eyes closed, on soft ground;
HR = Head turned to right, eyes closed, on hard ground; HL = Head turned to left, eyes closed, on hard ground;
HB = Servical extension, eyes closed, on hard ground; HF=Cervical flexion, eyes closed, on hard ground.
SI = Stability index; higher values indicate worse postural stability.
ICC = Intraclass correlation coefficient.
