Stroke survivors are inclined to consciously control their movements, a
phenomenon termed "reinvestment".
Preliminary evidence suggests reinvestment to
impair patients' motor recovery. To investigate this hypothesis, an instrument is
needed that can reliably assess reinvestment post-stroke. Therefore, this study
aimed to validate the Movement-Specific Reinvestment Scale (MSRS) within
inpatient stroke patients. METHOD: One-hundred inpatient stroke patients (<1 year
post-stroke) and 100 healthy peers completed the MSRS, which was translated to
Dutch for the study purpose.
To assess structural validity, confirmatory factor
analysis determined whether the scale measures two latent constructs, as
previously reported in healthy adults. Construct validity was determined by
testing whether patients had higher reinvestment than controls. Reliability
analyses entailed assessment of retest reliability (ICC), internal consistency
(Cronbach's alpha), and minimal detectable change.
RESULTS: Both structural and
construct validity of the MSRS were supported. Retest reliability and internal
consistency indices were acceptable to good. The minimal detectable change was
adequate on group level, but considerable on individual level. CONCLUSIONS: The
MSRS is a valid and reliable tool and suitable to assess the relationship between
reinvestment and motor recovery in the first months post-stroke. Eventually, this
may help therapists to individualize motor learning interventions based on
patients' reinvestment preferences. Implications for rehabilitation This study
showed that the Movement-Specific Reinvestment Scale (MSRS) is a valid and
reliable tool to objectify stroke patients' inclination for conscious motor
control. The MSRS may be used to identify stroke patients who are strongly
inclined to consciously control their movements, as this disposition may hinder
their motor recovery. Eventually, the MSRS may enable clinicians to tailor motor
learning interventions to stroke patients' motor control preferences.
