Low-frequency repetitive transcranial magnetic stimulation (rTMS) of the unaffected hemisphere can enhance function of the paretic hand in patients with mild motor impairment. Effects of low-frequency rTMS to the contralesional motor cortex at an early stage of mild to severe hemiparesis after stroke are unknown. In this pilot, randomized, double-blind clinical trial we compared the effects of low-frequency rTMS or sham rTMS as add-on therapies to outpatient customary rehabilitation, in 30 patients within 5-45 days after ischemic stroke, and mild to severe hand paresis.

- A study on 21 patients with HTLV-1 associated myelopathy/tropical spastic paraparesis used conventional MRI to evaluate its effectiveness in diagnosing the disease.
- Over half of the patients showed nonspecific brain abnormalities, primarily in deep white matter, but there was a lack of correlation between MRI findings and clinical symptoms.
- MRI proved to be a sensitive but not very specific diagnostic tool for this condition, as spinal cord abnormalities were also rare and no unique lesions were identified.
