Detailed Descriptions
| Sequence: | 20841919 |
| Description | During the modified lean-and-release test, there are two possible settings: 1) the leg block is placed in front of both legs, and a safety handle is uncovered; or 2) the leg block is removed, and the safety handle is covered. The leg block and handle cover will be controlled via computer-triggered, servo motors. The testing session will be comprised of three blocks: 1) REACH (grasping a safety handle using their right hand while maintaining both feet fixed), 2) STEP (stepping forward using any leg), and 3) RANDOM (random variations of STEP and REACH). |

To represent a composite measure of accuracy and speed of response, rapid response accuracy will be calculated using the ratio of response accuracy to the reaction time (%/ms). Foot-off and hand contact data will be used for the calculation. | Description | During the REACH, STEP, and RANDOM blocks, the quality of the compensatory reactions will be scored using the Reactive Postural Control section of the Mini-Balance Evaluation Systems Test. The scores will be ranged from 0 (worst) to 2 (best). | Description | Hand contact time during REACH following the cable release will be calculated. | Description | Foot-off time during STEP following the cable release will be calculated. | Description | Foot contact time during STEP following the cable release will be calculated. | Description | For the RANDOM block, response accuracy, defined as the percentage of accurate responses, will be calculated.
