Temporal-spatial feature of gait after traumatic brain injury.

The temporal-spatial characteristics of the gait of patients with traumatic brain injury (TBI) were investigated and compared with those of normal gait and the gait of stroke survivors. A slower walking velocity is evident in the TBI population when compared with normal. The average walking speed of TBI survivors is faster than that of stroke patients and is mainly related to a longer step length. TBI survivors produce a gait pattern with a prolonged stance period for the unaffected limb, without prolonged stance period for the affected limb, and a shorter step length for the unaffected limb.
