clinics completed: 3 English and 3 Spanish. 32 participants completed 6-
month follow up. Phase 2 (nZ59) and formative evaluation are in progress.
Conclusions: HEALS Phase 1 suggests that a six week lifestyle manage-
ment program consisting of a 2-hour small group format, healthy lifestyle
content, and led by an occupational therapist may be feasible for the
proposed population. Phase 2 will confirm these notions.

Recollection Training in Stroke Survivors: A Pilot Study
Janine Jennings, Lisa Walker, Ves Stamenova (Rotman ResearchInstitute at Baycrest), Fu-Qiang Gao, Shaun P. Cook, Andra Smith,Patrick Davidson
Objective: To examine the feasibility and effectiveness of a recollection
memory training paradigm.
Design: A single-blind non-randomized trial.
Setting: Community setting.
Participants: Eighteen stroke patients and thirty healthy age-matched
control participants.
Interventions: All participants performed three self-adaptive training
sessions per week for two weeks. Each training day, they completed four
sessions (each session involved studying one word list and then performing
a recognition memory test).
Main Outcome Measure(s): Training task improvement was established
based on the number of levels each participant gained in the training. To
establish transfer effects, participants were assessed at baseline and
post-training on a series of neuropsychological measures of working
memory, verbal and visual long-term memory, and source memory.
Clinical MRI and CT scans were used to establish stroke lesion size
and location.
Results: A repeated measures ANOVA showed that the patients and
controls improved to similar degrees on the training task. Significant
transfer effects following training were observed only in backward digit
span. Changes in forward digit span, digit symbol, and spatial source
memory scores approached significance. These effects were observed in
both groups of participants. We found no obvious link between lesion
location and training gains.
Conclusions: Although we found that many stroke patients can improve on
the training task itself to the same degree as healthy controls, we found
little evidence for transfer of training.However, the trainingwas tolerated
by all the patients, including the most impaired ones, and should be further
explored in future work.

Independent Mobility and Physical ACtivity Training (IMPACT) on aStroke Rehabilitation Unit: A Pilot Study
Vincent DePaul (Toronto Rehabilitation Institute),Wieslaw Jan Oczkowski, Michaela Ferguson, Laurie Wishart
Objective: To test the feasibility of a novel program that aims to engage
inpatients with stroke in extra task-oriented walking-related practice
outside of supervised physical therapy sessions.
Design: Prospective cohort pilot study.
Setting: Inpatient stroke rehabilitation unit.
Participants: Convenient sample of 10 adults (mean age Z 62.3 years
[MIN 37, MAX 78]) admitted to a subacute inpatient stroke rehabilita-
tion unit.
Interventions: The IMPACT program is based in principles of motor
learning (abundant, task-oriented practice), self-management, and self-

determination theory. Patients negotiated a walking-related goal, devel-
oped a plan to practice walking-related activities outside of therapy, and
implemented, monitored and progressed the plan with intermittent thera-
pist guidance.
Main Outcome Measure(s): Feasibility outcomes included successful goal
setting, practice plan development and completion, and change in gait
speed (GS), six minute walk test (SMWT), Functional Ambulation Clas-
sification (FAC), and Functional Independence Measure (FIM) over the 2
week intervention.
Results: Nine of 10 participants developed and initiated an independent
walking task-oriented activity plan. On 70% of study days, participants
completed or exceeded their negotiated practice. Eight of 10 participants
carried out the practice independently and reported that they would
continue beyond the study period. On average participants made mean-
ingful changes in FAC scores (Median 2, MIN 0 MAX 3), GS (Median
0.21 m/s [min 0.04 MAX 1.08]) m/s); FIM (Median Z 25 [MIN 4, MAX
54]); 6MWT (MedianZ 65 m [MIN 8, MAX 190]). There were no falls or
serious adverse events.
Conclusions: The IMPACT program was shown to be safe, feasible
method of engaging inpatients with stroke in additional task-oriented
practice. A randomized controlled cluster trial is planned to further eval-
uate this novel intervention.

Relationship Between Step Length, Cadence and Capacity to IncreaseGait Velocity After Recent Stroke
Vincent DePaul (Toronto Rehabilitation Institute - UHN),Kara Kathleen Patterson, Elizabeth L. Inness, Avril Mansfield,George Mochizuki, William McIlroy
Objective: 1) To quantify the capacity for individuals with recent stroke
to increase gait velocity from comfortable to maximum pace during
overground walking; 2) To describe the relationship between step length
[SL], cadence [Cad], the ratio of SL:Cad, and capacity to in-
crease velocity.
Design: Retrospective chart review.
Setting: Inpatient stroke rehabilitation
Participants: Consecutive sample of 245 ambulatory adults (age 67.6
years [SD 13.9]) admitted to an inpatient stroke rehabilitation unit.
Interventions: Not applicable.Main Outcome Measure(s): Gait parameters (velocity, step length [SL],
cadence [Cad] and the ratio of SL:Cad) at comfortable velocity (CV),
and maximal velocity (MV) were measured using the GAITRite System.
Increase in gait velocity was calculated as difference between MV
and CV.
Results: The mean difference between CV and MV gait velocity was 0.32
(SD 0 .19; 95% CI[4.6, 61.4]) m/s with only 0.04 % of participants
demonstrating no difference between MVand CV. Increase in gait velocity
was positively associated with SL (rZ0.48, p <0.0001), SL:Cad ratio
(rZ0.27, p <0.0001), and Cad (rZ0.26, p <0.0001). Participants with
greater increase in gait velocity (MV-CV) had a significantly greater
SL:Cad ratio during CV (F[3, 238]Z 7.23 , p < 0.0001) and MV walking
(F[3,238]Z 10.14, p<0.0001).
Conclusions: On average, this group of ambulatory inpatients with recent
stroke was able to substantially increase their overground gait velocity. A
strategy that favored increased step length over cadence was positively
associated with an increased differential between CVand MV. It is possible
that training targeted to increasing step length over cadence may help
patients adopt a more effective strategy to increase gait velocity
following stroke.
