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.

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 (Median Z 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.

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.

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
