Can overestimation of walking ability increase the risk of falls in people in the subacute stage after stroke on their return home?

- In subacute stroke patients, measures on the 10MWT and 6mWT are needed.
- Comparisons of the 10MWT and 6mWT can be used to identify at-risk patients.
- Clinicians should train stroke patients to be aware of their new motor abilities.

PurposeFalls are common in patients who have had a stroke who return home after neurorehabilitation. Some studies have found that walking speed inversely correlates with the risk of falls.ScopeThis study examined whether comparison between comfortable self-selected walking speed and maximum maintainable speed is informative with regard to the risk of falls in patients with stroke.MethodsA prospective cohort study was performed with 75 ambulant stroke patients. At discharge, the Barthel Index score and performance at the 10-m and 6-min walking tests were assessed. Number of falls was recorded by telephone interview every two months for one year. Regression analysis was performed to identify factors that were related to the risk of falls.ResultsUsing forward multiple linear regression, only the ratio between walking speeds on the 6-min and 10-m tests was linked to the number of falls in the year after discharge (R = −0.451, p < 0.001, OR = 0.046). Patients who chose a walking speed for short distances that was not maintainable long term fell more frequently.ConclusionsA discrepancy between short and long-term walking speed can help in identifying subjects in the subacute stage after stroke with an increased risk of suffering a fall.
