Observation of amounts of movement practice provided during stroke rehabilitation.

UNLABELLED: Lang CE, MacDonald JR, Reisman DS, Boyd L, Jacobson Kimberley T, Schindler-Ivens SM, Hornby TG, Ross SA, Scheets PL. Observation of amounts of movement practice provided during stroke rehabilitation. OBJECTIVE: To investigate how much movement practice occurred during stroke rehabilitation, and what factors might influence doses of practice provided. DESIGN: Observational survey of stroke therapy sessions. SETTING: Seven inpatient and outpatient rehabilitation sites. PARTICIPANTS: We observed a convenience sample of 312 physical and occupational therapy sessions for people with stroke. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: We recorded numbers of repetitions in specific movement categories and data on potential modifying factors (patient age, side affected, time since stroke, FIM item scores, years of therapist experience). Descriptive statistics were used to characterize amounts of practice. Correlation and regression analyses were used to determine whether potential factors were related to the amount of practice in the 2 important categories of upper extremity functional movements and gait steps. RESULTS: Practice of task-specific, functional upper extremity movements occurred in 51% of the sessions that addressed upper limb rehabilitation, and the average number of repetitions/session was 32 (95% confidence interval [CI]=20-44). Practice of gait occurred in 84% of sessions that addressed lower limb rehabilitation and the average number of gait steps/session was 357 (95% CI=296-418). None of the potential factors listed accounted for significant variance in the amount of practice in either of these 2 categories. CONCLUSIONS: The amount of practice provided during poststroke rehabilitation is small compared with animal models. It is possible that current doses of task-specific practice during rehabilitation are not adequate to drive the neural reorganization needed to promote function poststroke optimally.

Counting repetitions: an observational study of outpatient therapy for people with hemiparesis post-stroke.

Given the contemporary clinical belief that more practice is better, it is important to determine how much practice currently occurs during physical therapy (PT) and occupational therapy (OT). The purpose of this study was to examine the number of repetitions of various activities during PT and OT outpatient treatment sessions for people with hemiparesis post-stroke. We observed 36 treatment sessions and recorded the types of activities and the number of repetitions of each activity that were done. Observations were categorized and descriptive statistics were generated for each category and subcategory. Our results showed that treatment time averaged 36 minutes per session. In sessions addressing the upper extremity, the average number of repetitions per session were 39 for active-exercise movements, 34 for passive-exercise movements, and 12 for purposeful movements. In sessions addressing the lower extremity, the average number of repetitions per session were 33 for active-exercise movements, six for passive-exercise movements, and eight for purposeful movements. In sessions addressing gait, the average number of steps taken was 292. In sessions addressing transfers, the average number of repetitions per session was 11. For most categories, there was considerable variability in the number of repetitions observed. We conclude that the numbers of repetitions observed during PT and OT for people with hemiparesis post-stroke are relatively small, except for gait steps. The fact that the number of repetitions of upper extremity purposeful movements was smaller than the number of repetitions of upper extremity active- and passive-exercise movements was surprising. This finding is inconsistent with current teaching that practice of purposeful movements is an integral part of improving functional status.
