 | | Gait speed, chair rise time, and the ability to perform tandem stance (one foot in front of the other) are independent predictors of the ability to perform instrumental activities of daily living (IADLs)--eg, the ability to shop, travel, and cook. |
 | | Gait speed, chair rise time, and balance are also predictors of the risk of nursing home admission and death. |
 | | Gait initiation failure due to high-level sensorimotor (frontal lobe or white matter) disorder may progress to other abnormalities, including stiff posture with short steps, retropulsion (falling backward) in stance, weak or poor corrective responses to perturbations of balance when walking, and a highly variable and unstable gait pattern. |
