We have experienced a surgeon who had a previous left putaminal hemorrhage and presented with higher brain dysfunctions due to a new right frontal lobe infarction. The patient was a right-handed man in his 50s with inattention, constructive disorder, left hemispatial neglect, and executive dysfunction. The lesions were localized not only in the right inferior and middle frontal gyri but also in deep white matter including the right frontal aslant tract and superior longitudinal fasciculus. The patient gradually resumed work early on with multidisciplinary support and returned to work within 3 months after the onset of the disease. In this case, direct attention training, metacognitive strategy training including time pressure management, and visual search training from the acute stage were successful. Even after the completion of cognitive rehabilitation, an improvement in attention and processing speed was confirmed, suggesting that highly personalized cognitive rehabilitation tailored to higher brain dysfunctions have a lasting effect. However, the improvement of higher brain functions and the resumption of work increased self-awareness and anxiety, leading to a decrease in self-efficacy. Cognitive rehabilitation including metacognitive strategy training, together with psychological support, is important for step-by-step return to work.

Rehabilitation for ocular motility disorder and diplopia after acute cerebral infarction has not been established. In the present case, we describe the course of oculomotor rehabilitation in a patient with left-sided gaze palsy and diplopia due to a stroke in the paramedian part of the left pontine tegmentum. The patient was a right-handed man in his 40s. Cerebral infarction occurred after coil embolization with stenting for an unruptured dissecting aneurysm. He presented with eye movement difficulty resulting from conjugate deviation of the eyes to the right at onset. No other motor-sensory abnormalities were present. Processing speed of Wechsler Adult Intelligence Scale-Fourth Edition was decreased. We performed oculomotor rehabilitation from the acute phase, including fixation, smooth pursuit, saccadic and convergent movements. Visual attention tasks such as visual search and cancellation tasks were applied from 10 days after onset. The oculomotor disorders gradually improved and disappeared by 65 days after onset. The responsible lesion was localized in left paramedian pontine reticular formation and abducens nucleus. Medial longitudinal fasciculus was not involved, which was consistent with the clinical oculomotor findings. The neuropsychological assessments showed that processing speed was improved. Based on the neuropsychological assessments and actual vehicle evaluation, our multidisciplinary team determined that the patient should not refrain from automobile driving. The patient returned to work and resumed driving 86 days after onset. The results suggest that visual attention tasks together with basic oculomotor trainings for ocular motility disorder and diplopia are useful for early return to automobile driving and society.

Few reports have yet investigated adequate cognitive rehabilitation for patients with chronic cognitive disorder. In this report, we describe a case of cognitive rehabilitation 10 months after onset of cerebral infarction in the right middle cerebral artery region, resulting in a good outcome. The patient was a 44-year-old right-handed male, with primary symptoms of inattention and left hemispatial neglect. The patient had not undergone any neuropsychological evaluations or cognitive rehabilitation until 10 months after disease onset. After 30 days of both direct attention training and metacognitive strategy training, including time pressure management, improvement of his cognitive disorder was achieved. The teaching of internal methods to improve metacognition with a high level of evidence was effective even 10 months after onset. Furthermore, it is important for therapists who provide cognitive rehabilitation using metacognitive strategy training to understand patients' remaining functions based on neuropsychological assessment, and to consider and teach compensatory methods so that they can be effectively used by patients in situations of daily life.

Objects：Sit-to-stand (STS) interventions are frequently used as part of stroke rehabilitation. This study aimed to clarify the kinematic and kinetic characteristics of patients recovering from stroke, who have difficulties with STS movement.Method：The participants included 26 stroke patients who struggled to complete the STS maneuver. Using a 3D motion analysis system, the kinematic and kinetic parameters during STS were retrospectively analyzed and compared between failed and successful trials. The kinematic parameters of the trunk and lower limbs were obtained within the seat-off phases, and the kinetic indices of the lower limbs were obtained from measurements taken before and after the seat-off phase. The weight-bearing ratio on the unaffected side was calculated from the vertical ground reaction forces.Results：In the successful trials, analyses of the parameters revealed more forward tilting of the pelvic and thoracic regions, a further forward and downward shift of the center of mass, and larger hip and knee extension moments than those of the failed trials. However, there was no difference in the weight-bearing ratio on the non-paralyzed side.Conclusion：This study revealed that the kinematic and kinetic properties of the STS maneuver differed between successful and failed trials among patients with stroke. The study therefore provides useful information for clinical evaluation and rehabilitation.

Objective: Combination therapy with glecaprevir and pibrentasvir (G/P) has been shown to provide a sustained virologic response (SVR) rate of >97% in patients with chronic hepatitis C virus (HCV) infection in the first published real-world Japanese data. However, a recently published study showed that the treatment was often discontinued in patients ≥75 years old, resulting in low SVR in intention-to-treat (ITT) analysis. Thus, our aim was to evaluate real-world data for G/P therapy in patients ≥75 years of age, the population density of which is high in “rural” regions.Patients and Methods: We conducted a multicenter study to assess the efficacy and safety of G/P therapy for chronic HCV infection, in the North Kanto area in Japan.Results: Of the 308 patients enrolled, 294 (95.5%) completed the treatment according to the protocol. In ITT and per-protocol analyses, the overall SVR12 rate was 97.1% and 99.7%, respectively. The old-aged patients group consisted of 59 participants, 56 of whom (94.9%) completed the scheduled protocol. Although old-aged patients tended to have non-SVR factors such as liver cirrhosis, history of HCC, and prior DAA therapies, the SVR12 rates in old-aged patients were 98.3% and 100% in the ITT and PP analyses, respectively. Of 308 patients enrolled, adverse events were observed in 74 patients (24.0%), with grade ≥3 events in 8 patients (2.6%). There was no significant difference in any grade and grade ≥3 adverse events between the old-aged group and the rest of the study participants. Only one patient discontinued the treatment because of adverse events.Conclusion: G/P therapy is effective and safe for old-aged patients.

Levetiracetam (LEV), a relatively new antiepileptic drug, is now frequently used for treating partial or generalized seizures. Among the adverse effects of LEV, rhabdomyolysis is rare. We describe here a case of LEV-induced rhabdomyolysis in a 26-year-old woman. The patient’s seizures had been controlled with carbamazepine and phenobarbital for the previous 7 years. However, LEV was initiated at the age of 26 years because her seizures control deteriorated with seizures occurring monthly. She experienced lower limb weakness with a high level of creatine kinase 15 days after starting LEV. When LEV was discontinued, her creatine kinase levels decreased and her symptoms gradually improved. This case provide another example of rhabdomyolysis during the early phase of LEV treatment.

Objective : The purpose of this clinical research was to create an assessment for patients with muscle disease who wish to continue driving by investigating their motor function and driving experience. Methods : Twenty-four patients with muscle disease who visited our hospital from December 2009 to April 2010 were enrolled in our research. For patients who were still driving, physiatrists evaluated their motor functions, examined simulated driving motions and recorded their driving capabilities and techniques, their ability to get into and out of the vehicle and their ability to store and remove their wheelchairs. Patients no longer driving were asked why they had given up driving. Results : Fifteen patients who continued driving had enough upper limb strength and could simulate driving motions, though the location and degree of their muscle weakness were variable. Five of fifteen drove with the aid of a hand-operated brake and accelerator. Seven needed personal assistance: three to get into and out of the vehicles, six to store and remove wheelchairs. The nine patients who had stopped driving reported that the primary reason for discontinuing driving was that they recognized their muscles were insufficient to control the vehicle. Conclusions : We propose to evaluate muscle strength and to test simulated driving motions when assessing patients with muscle disease. A hand-operated brake and accelerator is efficient for patients with lower limb muscle weakness. However, since no efficient automobile modifications are available for those patients who cannot get into and get out of their vehicles or store and remove their wheelchairs by themselves, we suggest arranging personal assistance for such patients.
