Brief Summary

The purpose of this study is to explore whether an external focus or internal focus of attention leads to improved motor performance and learning with increased use of the affected side during sit to stand in individuals post stroke. Focus of attention refers to what a person is thinking about during a task, with an internal focus being thinking about what one's body is doing and an external focus being thinking about a target or outcome in the environment. A second purpose is to determine whether improved symmetry in sit to stand carries over to gait symmetry in individuals post stroke.

Outcome Measures

Primary Outcomes (14)

• Center of pressure under their feet

  HR Pressure mat - Symmetry under the feet will be measured using a 61.26 X 58.72 cm pedobarograph with a 48.8 X 44.7 cm active sensing area during the sit to stand transition. The mat has 3.9 sensors/cm2 with a 185 Hz scanning rate. The mat will be calibrated prior to the start of the study.

Study Arms (2)

Internal focus of attention group

ACTIVE COMPARATOR

Participants will be given instructions that make them think about their body's movements. Participants will complete the external focus group second in the cross over.

Other: Focus of Attention

External focus of attention group

EXPERIMENTAL

Participants will be given instructions that make them think about an outside target or outcome. Participants will complete the internal focus group second in the cross over.

Other: Focus of Attention

Interventions

Focus of Attention OTHER

Focus of attention instruction and feedback. Focus of attention refers to what people are thinking about during motor tasks. An external focus refers to thinking about an outside outcome or target. An internal focus of attention refers to thinking about how someone is moving their body.
