**5. Conclusions**

The validity of the estimations of the walked distance by wearable sensors varied significantly according to the device's type and location. Following our results, we recommend using a pedometer (piezoelectric device) worn on the hip on the unaffected side, or the Actigraph activity monitor (triaxial accelerometer) worn on the ankle on the unaffected side to estimate the walked distance in individuals with neurological sequelae of stroke.
