RESUMEN
Alien hand syndrome (AHS) is a rare neurologic disorder in which movements are performed without conscious will. Cognitive rehabilitation is usually first considered for treating AHS. However, we proposed different modalities for the treatment. This is the first case report showing therapeutic effects of the NEURO-15 program that consists of low-frequency repetitive transcranial magnetic stimulation and intensive occupational therapy on AHS symptoms and upper limb dysfunction caused by a stroke one year and three months before. A 68-year-old male developed right upper limb palsy secondary to cerebral infarction on the medial side of the left frontal lobe. On admission, he exhibited disturbed skilled motor behavior, compulsive grasping of the right upper limb, and dissociated behavior of the right hand independent from the left. The right hand interfered with the actions executed by the left hand. The left hand restricted the right hand in its actions by holding it. Six months after the onset, his Activities of Daily Living improved and he was discharged from hospital to home. However, his compulsive grasping of the right upper limb symptoms remained, and he underwent NEURO-15 one year and three months after the onset. His right upper limb function improved. Compulsive grasping of the right upper limb disappeared, and the contradictory action of the right upper limb was rarely seen. These results suggested that NEURO-15 influenced the neural network including the primary motor cortex and supplementary motor area.
RESUMEN
Background : The aim of this study was to assess the effects of repeated injections of botulinum toxin type A (BoNT-A) combined with a rehabilitative program for treating spastic upper limb hemiparesis after stroke. Subjects and methods: Subjects were 112 poststroke hemiparetic patients with spastic upper limb (mean age : 55.5±11.6 years ±SD, mean period between onset and first injection : 5.1±3.5 years). For each patient, BoNT-A (maximum dose of each injection : 240 units) was injected in the spastic muscles of the affected upper limb twice with a minimum interval of 3 months. Following each injection, detailed one-to-one instructions for homebased functional training was provided. At the baseline (before injection) and at 1 and 3 month follow-ups after each injection, the patient's modified Ashworth scale (MAS), the range of motion (ROM) and Fugl-Meyer Assessment (FMA) were evaluated. Results : The total score for the upper limb and the scores of categories A and B of the FMA increased significantly not only after the first injection but after the second injection compared with the second baseline, while the FMA score for category D increased significantly only after the second injection. MAS also decreased significantly not only after the first injection but after the second injection compared to the second baseline. Conclusion : A more significant improvement was found not only in muscle spasticity but also in upper limb motor function after two BoNT-A injections. It is suggested that repeated BoNT-A injections followed by a comprehensive rehabilitative program would be an effective treatment for limb spasticity after a stroke.
RESUMEN
We performed a 15 day protocol of low-frequency repetitive transcranial magnetic stimulation (rTMS) combined with intensive occupational therapy in hemiplegic upper limbs in poststroke and investigated the effect of cerebral blood flow using single photon emission computed tomography (SPECT). Seventeen chronic stroke patients were studied with SPECT at rest before and 4 weeks after undergoing the 15 day protocol. Before and after the treatment, Fugl-Meyer Assessment (FMA) score and Wolf Motor Function Test (WMFT) -Log performance time showed a significant improvement. The specific areas with a significant increase in perfusion in the affected hemisphere were the insula (BA 13), the precentral gyrus (BA 44) and the cerebellum. In the nonaffected hemisphere, perfusion was significantly increased in the lingual gyrus and cerebellum. On the other hand, perfusion was significantly decreased in the middle frontal gyrus (BA 6), precentral gyrus (BA 4) and postcentral gyrus (BA 3) in the nonaffected hemisphere. It was suggested that low-frequency rTMS combined with intensive occupational therapy effects the cerebral blood flow and contributes to improving upper limb hemiplegia after stroke.
