The patient, a 72-year-old man, was admitted for disuse syndrome after left lower thigh cellulites, who originally developed left hemiparesis at age 60. At the time of admission, he was alert, his Body Mass Index was 18.5 and his FIM (Functional Independence Measure) score was 49. We thought this was a case of post stroke disuse syndrome manifesting after long-term bedridden inactivity. He underwent a hospital rehabilitation program; however, he gained only poor functional recovery after one month. He complained about nighttime snoring and awakening from sleep. So he was evaluated with a portable device for SAS (Sleep Apnea Syndrome). His ESS (Epworth Sleepiness Scale) was 21, his Apnea-Hypnea Index was 58.2 and his lowest SpO₂ level was 75%. With a diagnosis of severe SAS, he was treated with nighttime nCPAP (nasal Continuous Positive Airway Pressure). After treatment, his lowest SpO₂ level rose to 90%, and the patient's excessive daytime sleepiness (ESS=15) and ADL (FIM=85) improved. When patients exhibit poor recovery after training, the possibility of SAS should be taken into consideration and they should be tested accordingly.

We report a case of Nothnagel syndrome with inattention. A 69-year-old laborer was admitted to our hospital for rehabilitation therapy complaining of gait disturbance a month after the onset of brainstem infarction. He had right oculomotor palsy, ataxia on the left side and upward movement limitation of the left eye. Magnetic resonance imaging demonstrated high signal intensity in the right tegmentum of the midbrain and the medial aspect of the right thalamus on T2-weighted and diffusion weighted images. This lesion involving nuclei in the medial aspect of the right thalamus, which is considered to be closely related with the reticular activating system, might explain his inattention. And it is suggested that the low blood flow in the right basal ganglia and parietal lobe revealed by his SPECT scan, could be related with that as well. We administered rehabilitation programs for his ataxia and inattention. Because diplopia is thought to be difficult to improve, we did not attempt to treat the patient's eye movement limitation. Three months after our intervention, he was able to walk without support. However, his inattention remained. Patients with brainstem infarction are apt to have plural impairments concurrently. In such cases, it is necessary to assess the treatment priority for each impairment adequately. Evidence based guidelines for the assessment of treatment priority would aid in this endeavor and the development of such guidelines is therefore expected.

The purpose of this study was to resolve the confusion existing in the terminology for describing foot motion, particularly the definitions of inversion and eversion. First, the definitions of foot motion used by the Japanese Association of Rehabilitation Medicine and the Japanese Orthopedic Association were compared with those used by the American Orthopaedic Foot and Ankle Society (AOFAS) and with those used by the International Society of Biomechanics (ISB), to identify agreements and differences. Next, the terminology utilized in the literature was explored by examining several major textbooks and related academic papers retrieved through a search of the PubMed medical literature database. In the definitions of AOFAS and ISB, inversion and eversion, which correspond to triplane motions in the definition used in Japan, were regarded as motions in the coronal plane. Terminology in the textbooks was very diverse. Of the 141 academic papers explored, 92 papers (66%) regarded inversion/eversion as coronal plane motion, and 4 papers (3%) regarded it as a triplane motion. In the remaining 43 papers (31%), the definition was unspecified. In academic articles addressing foot motions, to avoid confusion in terminology, the definitions of inversion and eversion need to be specified.
