Focus of Attention in Individuals With Stroke

3 stycznia 2021 zaktualizowane przez: Ashley Hyatt, Western Carolina University

Focus of Attention Effects on Motor Performance and Learning in Individuals Post Stroke During Seated Lateral Weight Shifting: A Two-phase Feasibility Study

This two phase feasibility study looked at the feasibility of conducting a clinical trial in the outpatient and inpatient rehab setting exploring how individuals post stroke respond to different focus of attention cues. Focus of attention refers to whether individuals in are thinking about how their body is moving, internal focus, or on the effect their body has on the environment, external focus, during motor task. This trial will specifically look at the effect focus of attention has on motor performance and learning in individuals post stroke during lateral seated weight shifting task.

Szczegółowy opis

This was a two phase feasibility study exploring appropriate management, setting, participants including inclusion and exclusion criteria, attrition rates, protocol, and retention. Outcome data for each stage were collected during baseline, acquisition, short-term, and long-term retention.

There were two primary objectives of this two phase feasibility study. The first was to uncover some potential short comings in research designs used in this area. The second was to explore the feasibility of a study in both the chronic and acute stroke populations in a rural community. Topics of feasibility include recruitment, retention, and specific inclusion and exclusion criteria. Extending the work by Muckel and Merholz, this feasibility study examined performance of individuals post stroke during a seated lateral weight shifting task and incorporated retention trials, quality of movement exploration, and bilateral weight shifting.

During Phase I, individuals in both groups sat unsupported on a hi-lo mat table which was adjusted so participants were sitting at 90 degrees hip and knee flexion with feet shoulder width apart. Tape marks were used to mark initial set up ensuring standardized positioning for each trial. Following baseline trials, all participants watched the same instructional video describing lateral weight shifting. The instructions included correct mechanics that should be used when weight shifting laterally with focus on correct form needed for the movement.

Testing included baseline, acquisition, short term retention (5 minutes later), and long-term retention (7-10 days later). Participants performed three trials of seated weight shifting to each side at all timepoints. During acquisition, the internal focus group was instructed to "shift your weight as much as possible towards your right or left hip without using your arms". The external focus group sat with targets one arm length away at shoulder height and were instructed to "shift your body weight as much as possible towards the blue/orange target without using your arms." During baseline and retention trials, adults were instructed to "lean as far as you can to the right/left without using your arms." During Phase II, the protocol was similar except 6 trials were performed for acquisition to potentially improve motor learning, which was not significant in Phase I per retention data. Other changes to the protocol included allowing participants to move their feet when weight-shifting. Instructions were also revised. The external focus group was told to "move your shoulder as close to the blue/orange target as possible", while the internal focus group was told to "shift your body weight as much as possible towards your right/left hip without using your arms."

Shoulder alignment during baseline to affected side
Ramy czasowe: baseline (prior to training)

Only used in arm 2 of the study. Angle measuring a line from acromion to acromion compared to a horizontal plumb line. This is a repeated measure over 4 time points. This measurement will occur during each lateral weight shift for all participants. Pt's will shift to either side 3 times during baseline, short term and long term retention. Participants shifted to both sides 6 times to each side during arm 2 of the study. Averages were used for data analysis.
