Abstract
Study design
Qualitative
study to identify themes and explore mechanisms underlying recovery of
hand function post stroke for individuals discharged from rehabilitation
services.
Purpose of the study
Post-stroke
hemiparesis frequently results in persistent hand dysfunction; the
mechanisms of functional recovery are however poorly understood. We
assessed the perspectives of community-dwelling individuals with chronic
stroke on their hand function limitations and recovery to explore the
feasibility of developing a theoretical framework for understanding the
process of continued post-stroke recovery.
Methods
Eight
subjects with chronic post-stroke hemiparesis were interviewed and
videotaped while they performed a battery of 20 upper limb tasks.
Qualitative analysis consisted of two investigators independently
reviewing the videotapes and reading the transcribed conversations,
identifying significant issues and then comparing their observations to
determine common themes and develop emerging concepts.
Results
Four
core themes pertaining to impairment and recovery of task-specific
ability emerged: 1) spasticity can be overcome actively through
task-specific attempts to use the affected arm and hand; 2) use of the
affected arm can be facilitated by adopting positions that reduce the
effect of gravity on the arm or enable gravity to act as a natural
assist in the movement; 3) task-specific skill can be attained by
repeatedly attempting specific component movements of tasks in the
context of a variety of different tasks; and 4) frustration impedes task
performance but a mental state of ‘detached focus’ can improve the
motivation to use the affected arm.
Conclusions
These
themes suggest a therapeutic framework for continued upper limb
rehabilitation in patients' own environment to maximize functional
recovery in individuals long after their stroke, and generate hypotheses
which may lead to the development of new therapeutic protocols.
