文摘

•: Poststroke participants had a wide range of haptic performance, the majority were impaired.
•: A good relationship was found between ipsilesional Thal–M1 integrity and poststroke haptics.
•: Around 90% of haptic performance was predicted by frontoparietal white matter integrity.
•: Precuneus interhemispheric tract integrity was a strong predictor of haptic performance.
•: Diminished integrity across the frontoparietal network suggests a general stroke-related factor.
