  1. The table shows results of waveform analysis of patient bending at the waist to touch ground and returning to standing posture, columns 2–4 show mean ICP before the inflexion of the ICP rise due to the bending event, during the event and following the inflexion at the end of the event. Columns 5–7 show comparison between the values before and during the event. Columns 8–10 show comparison between values before and after the event
