Abstract
Background. Optimal physical
therapy strategies to maximize locomotor function in patients early
poststroke are not well established.
Emerging data indicate that substantial amounts of
task-specific stepping practice may improve locomotor function, although
stepping practice provided during inpatient
rehabilitation is limited (<300 steps/session).
Objective. The purpose of this investigation was to determine the feasibility of providing focused stepping training to patients early
poststroke and its potential association with walking and other mobility outcomes.
Methods.
Daily stepping was recorded on 201 patients <6 months poststroke
(80% < 1 month) during inpatient rehabilitation following
implementation of a focused training program to
maximize stepping practice during clinical physical therapy sessions.
Primary
outcomes included distance and physical assistance
required during a 6-minute walk test (6MWT) and balance using the Berg
Balance Scale (BBS). Retrospective data analysis
included multiple regression techniques to evaluate the contributions of
demographics, training activities, and baseline
motor function to primary outcomes at discharge.
Results.
Median stepping activity recorded from patients was 1516 steps/d, which
is 5 to 6 times greater than that typically observed.
The number of steps per day was positively
correlated with both discharge 6MWT and BBS and improvements from
baseline (changes;
r = 0.40-0.87), independently contributing 10% to 31% of the total variance. Stepping activity also predicted level of assistance
at discharge and discharge location (home vs other facility).
Conclusion.
Providing focused, repeated stepping training was feasible early
poststroke during inpatient rehabilitation and was related
to mobility outcomes. Further research is required
to evaluate the effectiveness of these training strategies on short- or
long-term mobility outcomes as compared with
conventional interventions.
