Gait after stroke: initial deficit and changes in temporal patterns for each gait phase.
OBJECTIVE
To examine which phases of the gait cycle contributed to decreased gait velocity after stroke.


METHODS
Experimental.


METHODS
Inpatient rehabilitation centers.


METHODS
Forty-two patients with unilateral first stroke who were able to walk 10 meters; and 42 age- and gender-matched controls with no history of stroke.


METHODS
Not applicable.


METHODS
Deficit and change expressed as duration (s) and proportion (%) for the 4 phases of the gait cycle at the time of admission to rehabilitation (test 1), a median of 31 days poststroke onset, and again 8 weeks later (test 2). Affected and unaffected single-limb support (SLS) and initial double-limb support (DLS) were compared.


RESULTS
At tests 1 and 2, the durations of the 2 DLS and unaffected SLS phases were significantly (p <.001) longer in the stroke patients than in control subjects. No difference was found between the 2 groups for duration of affected SLS at either test time. Significant (p <.001) decreases occurred over the 8-week period in the 3 phases identified to be abnormally long at test 1.


CONCLUSIONS
If the goal of rehabilitation is to increase gait velocity and normalize the gait pattern, treatment should focus on decreasing the DLS and unaffected SLS phases of the gait cycle.
