|  | At rest position (cm) | Initial position (normal position) (cm) | Final position (maximum distance) (cm) | Percentage change between initial and final position | Initial force (mean ± std.) (N) | Force after 1000 trials (mean ± std.) (N) | % force change: initial to 1000 | Force after 2000 trials (mean ± std.) (N) | % force change: initial to 2000 |
