Association between improvement in gait speed and white matter hyperintensities (WMH) volume proportional to total brain volume in the three longitudinal tracts (depicted as figure inserts) in the two intervention arms (Timing and coordination training (TC): open circles, walking, endurance, balance strength training (WEBS): closed circles).
2a: Superior Longitudinal Fasciculus (SLF)
2b: Inferior longitudinal fasciculus (ILF)
2c.Inferior fronto-occipital fasciculus (IFO):
