Background Repetitive transcranial magnetic stimulation (rTMS) and Repetitive facilitative exercise (RFE) improves motor impairment after stroke. Objective To investigate whether neuromuscular electrical stimulation (NMES) can facilitate the effects of rTMS and RFE on the function of the hemiparetic hand in stroke patients. Methods This randomized double-blinded crossover study divided 20 patients with hemiparesis into two groups and provided treatment for 4 weeks at 5 days/week. NMES-before-sham group and NMES-following-sham group performed NMES sessions and sham NMES sessions for each 2 weeks. Patients received NMES or sham NMES for the affected extensor muscle concurrently with 1 Hz rTMS for the unaffected motor cortex for 10 min and performed RFE for 60 min. The Fugl-Meyer Assessment (FMA), Action Research Arm Test (ARAT), Box and Block Test (BBT) and Modified Ashworth Scale (MAS) were used for evaluation. Results FMA and ARAT improved significantly during both sessions. The gains in the BBT during an NMES session were significantly greater than those during a sham NMES session. MAS for the wrist and finger significantly decreased only during an NMES session. Conclusions NMES combined with rTMS might facilitate, at least in part, the beneficial effects of RFE on motor function and spasticity of the affected upper limb.

Hereditary diffuse leukoencephalopathy with spheroids (HDLS) is a young-adult-onset autosomal dominant white matter disease characterized by progressive cognitive dysfunction. We herein report the case of a 20-year-old woman who developed spastic hemiplegia. Brain magnetic resonance imaging revealed increased bilateral T2 signal intensity and bright diffusion-weighted imaging signals with a low apparent diffusion coefficient within the frontoparietal white matter. The lesion gradually expanded for over one year. The patient was initially diagnosed with multiple sclerosis (MS); however, she did not respond to immunosuppressive therapy. DNA sequencing showed a heterozygous c.2381T>C mutation in colony-stimulating factor 1 receptor. HDLS with a pure motor phenotype is sometimes difficult to differentiate from MS.
