OBJECTIVE To investigate the effects of virtual reality (VR) on cortical reorganization and motor recovery. DESIGN Nonparametric pre- and posttest design with experimenter blinded. SETTING University medical center. PARTICIPANTS Five patients with hemiparesis (age, 59.8+/-3.4y) were recruited. INTERVENTION Five patients received VR for 60 minutes a(More)
Diffusion tensor tractography (DTT) is known to be useful in detecting white matter lesions. In the current study, we report on two hemiparetic patients with risk factors who showed abnormalities of the corticospinal tract (CST) on diffusion tensor tractography (DTT) prior to the manifestation of hemiparesis. Two hemiparetic patients with risk factors(More)
Active execution, proprioception, and touch discrimination are important for the execution of movement. In the current study, we attempted to compare the cortical activation patterns of active exercise, proprioceptive input, and touch stimulation in the normal human brain using functional MRI. Nine subjects were recruited for this study. Functional MRI was(More)
OBJECTIVES Little is known about the mechanism of motor recovery for patients with intracerebral hemorrhage (ICH). We attempted to demonstrate the motor recovery mechanism in a hemiparetic patient with ICH using diffusion tensor tractography (DTT), transcranial magnetic stimulation (TMS), and functional MRI (fMRI). SUBJECTS A 37-year-old female patient(More)

To explore the action mechanism of lithium in the brain, the author investigated the effects of lithium on Na-K ATPase and Ca ATPase in rat brain synaptosomes prepared from forebrains by the method of Booth and Clark. The activities of Na-K ATPase and Ca ATPase were assayed by the level of inorganic phosphate liberated from the hydrolysis of ATP. Lithium at(More)
Little is known about the clinical usefulness of diffusion tensor tractography (DTT) for the arcuate fasciculus (AF) in stroke patients with aphasia. Using DTT, we attempted to investigate the clinical usefulness of the AF in patients with aphasia. Five stroke patients and 7 age- and sex-matched normal subjects were recruited for this study. We recruited(More)
Diffusion tensor tractography (DTT) is useful for elucidating the status of the corticospinal tract (CST). The purpose of this study was to investigate the usefulness of DTT for determining the causes of motor weakness in patients with traumatic brain injury (TBI). Five patients with TBI were recruited for this study. DTT was performed using 1.5-T with a(More)
OBJECTIVES Constraint-induced movement therapy (CIMT) has been demonstrated to be effective in improving hemiparetic upper extremity function in stroke patients, but few studies have been performed to assess orthosis modification. We investigated the effect of the newly designed small orthosis named modified opposition restriction orthosis (MORO) in chronic(More)
OBJECTIVE To investigate the efficacy and safety of percutaneous intradiscal monopolar pulsed radiofrequency (PRF) in patients with chronic disabling discogenic back pain. METHOD Twenty-six subjects (7 males; mean age 43.2 years) with chronic back pain refractory to active rehabilitative management were recruited. All subjects underwent MRI for evaluation(More)
OBJECTIVE To investigate the effect on fine motor ability and the appropriate restriction period of constraint-induced movement therapy in hemiparetic patients with brain injury. DESIGN Nine chronic hemiparetic patients with brain injury were studied. After confirming the cessation of further recovery of fine motor ability by Purdue pegboard test and(More)
