Post-therapy improvement in nerve conduction studies is associated with somatotopically-specific post-therapy improvements in white matter microstructure. Longitudinal DTI analyses demonstrated somatotopic specificity for improvements following acupuncture therapy at distinct body sites (i.e. local versus distal acupuncture therapy arms). Specifically, reduction in median nerve latency was associated with decreased fractional anisotropy (FA) near (i) contralesional hand area following verum, but not sham, acupuncture; (ii) ipsilesional hand area following local, but not distal or sham, acupuncture; and (iii) ipsilesional leg area following distal, but not local or sham, acupuncture.
