Translation, reliability, and validation of the Dutch Safe Use of Mobility Aid Checklist (SUMAC-NL) for walker use in people living with dementia

Background: People with dementia have a yearly risk of falling 60 to 80 percent. Therefore, walker is often recommended. However, the use in people associated threefold increased odds falls compared their healthy peers. Better advice and training could reduce fall risk. tool assess functional walking skills needed. The SUMAC was developed fill this gap. So far, there no Dutch instrument available that can dementia. Methods: Reliability evaluated by scoring videos (n = 9) using performing SUMAC-NL. ICC used inter-rater test-retest reliability. An expert panel 8) content validity index (CVI) ratio (CVR). Results: Inter-rater reliability SUMAC-NL statistically significant for PF domain (ICC 0.94, 95%CI (0.84, 0.98, p < 0.001) EQ 0.79, (0.49 – 0.95), 0.001). Test-retest both 0.95, (0.89, 0.99), 0.92, (0.82, 0.98), shows CVI >0.79 domains CVR 0.53 on 0.78 domain. Conclusions: good excellent seems be promising Netherlands.
