Currently, predatory publishers and open access journals are flourishing in the academic field, including in the area of rehabilitation. Manca and colleagues proposed a list of suspected predatory rehabilitation journals. The purpose of this study was to assess the involvement of Japanese researchers in predatory rehabilitation journals. This study assessed and analyzed the websites of 59 predatory journals listed by Manca and colleagues. Among the 59 journals, research papers of only 39 journals could be accessed from the websites. Among these 39 journals, Japanese researchers were found to be the members of the editorial board in 16 journals and research papers by Japanese researchers were published in 24 journals. Predatory journals are threatening the field of rehabilitation research in Japan because Japanese researchers are involved in predatory rehabilitation journals. Thus, researchers should carefully select a journal when submitting a research paper.

This study reports a case of a paraplegic stroke patient who had difficulty walking with an ankle–foot orthosis, but was able to walk independently with a short knee–ankle–foot orthosis (semi-KAFO). A 34-year-old man presented with right hemiplegia due to left putaminal hemorrhage. At 143 days after the stroke onset, he could not obtain sufficient support for the paralyzed leg and required assistance during his walk with an ankle–foot orthosis because the knee joint of the paralyzed side was always flexed due to knee flexor hypertonia. Conversely, he was able to walk with a semi-KAFO under observation. He practiced putting on and taking off the semi-KAFO, standing, sitting, walking, and toileting with a semi-KAFO for three weeks. At 164 days after stroke onset, he was able to walk and toilet independently with a semi-KAFO. This study’s results indicate that a semi-KAFO is useful as a daily living orthosis for hemiplegic stroke patients who have difficulty walking with an ankle–foot orthosis due to increased knee joint flexor muscle tone.

While mirror therapy is used to improve upper limb function after stroke, evidence supporting its use for treating post-stroke complex regional pain syndrome remains inconclusive. We aimed to evaluate the therapeutic effects of mirror therapy for complex regional pain syndrome after stroke. The following databases were searched for relevant literature: MEDLINE, EMCARE, EMBASE, PsycINFO, CINAHL, Cochrane Central Register of Controlled Trials, Web of Science, OTseeker, and the Physiotherapy Evidence Database, with no restrictions on language, type, or date. Randomized controlled trials comparing mirror therapy with placebo interventions or other treatments for stroke and complex regional pain syndrome type 1 were included. Studies involving multiple trauma cases were excluded. Primary outcomes were pain, assessed using a visual analog scale, and upper limb function, evaluated using the Wolf Motor Function Test and Fugl–Meyer assessment. Risk of bias was assessed using the Cochrane Handbook for Systematic Reviews of Interventions. Of 2,977 screened articles, 17 were reviewed. Three studies fulfilling the inclusion criteria with moderate overall risk of bias were considered for data extraction. All three studies assessed pain using the visual analog scale; two assessed upper extremity function via the Wolf Motor Function Test or Fugl–Meyer assessment. Each of the three studies showed significant improvement in the mirror therapy group compared with the control group. This review validated mirror therapy as an effective treatment for complex regional pain syndrome type 1 after stroke; however, the quality of evidence remains very low.

Coronavirus disease 2019 (COVID-19) has a profound impact on our society, and health care professionals are challenged by the present outbreak. A recent study showed that a significant proportion of second-line workers and frontline workers experienced psychological distress. Although these findings suggest the possibility that rehabilitation therapists, especially those who work at the hospital, experience psychological distress, their mental health state has been largely dismissed and the number of an evidence-based practice is limited. Here, we discuss the importance of focusing on the mental health of therapists by introducing studies that focus on the mental health of health care workers during the COVID-19, SARS, and H1N1 influenza pandemics. We then noted the need to track the dynamic relationship between the mental health of therapists and the COVID-19 pandemic by employing longitudinal data collection with psychological measures that reliably and validly capture the mental health of therapists. This approach would be effective for preparation for future pandemics, as we have learned much from previous pandemics. We hope that our Tutorial Note will help readers who are interested in the mental health of rehabilitation therapists and encourage future studies.

Rehabilitation is a co-creative medical service that strongly requires patient involvement. Encouraging patients to continue rehabilitation is an important role of medical services, and evaluation technology is also important from that perspective. The evaluation technology for rehabilitation was developed from the physical structure evaluation using medical images to the physical function evaluation using motion capture, ground reaction force and digital human models. Also, the idea that what should be restored is not only physical function but also daily-living function has been advocated, and standard description and evaluation of daily-living functioning have been promoted since the latter half of the 1990s. Furthermore, since 2000, research to evaluate functional recovery of the cranial nervous system, which controls motor function recovery, has made rapid progress in the field of neuro-rehabilitation. The rehabilitation evaluation has been integrated by the evaluation of the physical function, daily-living functioning, and the functional recovery of the cranial nervous system. In the future, these three functional evaluation technologies will be implemented in cooperation with advanced medical equipment that can be used in hospitals and wearable equipment and nursing robots that can be used in daily life. We believe that each person will be able to continue their daily rehabilitation with motivation while confirming to what extent the effects of rehabilitation are exerted on their cranial nerves, motor functions, and daily-living functions.

The objectives of this study were to develop an oculomotor rehabilitation program by means of expert discussion, based on the results of a systematic review, that may be easily administered in clinical settings; it also aimed to evaluate the efficacy of the newly developed program in a single case. Four experts with extensive knowledge and experience of brain trauma rehabilitation (mean length of clinical experience 30.5  0.6 years) developed an oculomotor rehabilitation program on the basis of the types, duration, frequency, and timing of exercises previously found to be effective in available literature. In this program, a clinician indicated a target to the patient, who performed exercises to encourage fixation, saccade, pursuit, and vergence in sessions lasting 20 minutes a day, 6 days a week, for a total of 8 weeks. An immediate effect was evident after the first session, with an increase in oculomotor range of motion compared to before the session. The supraduction range of motion of the right eye increased from 1.44 mm before the start of the 8-week program to 4.36 mm after its completion; the patient’s ability to perform activities of daily living also improved. The use of this program improved contraction and weakness of the extraocular muscle, and increased the oculomotor range of motion.

There are few case reports of patients with hemiparetic stroke who had previously been diagnosed with poliomyelitis (polio). Herein, we present the case of an 84-year-old male stroke patient with right-sided hemiparesis and polio. He was infected with polio at age 6 and had severe right-leg palsy. He was able to walk independently, performed knee hyperextension, and walked using a cane prior to the stroke at age 84. He was transferred to our hospital 31 days post-stroke. At that time, manual muscle test (MMT) was Poor-to-Good for the right ankle muscles and Trace for the right hip and knee muscles. He required assistance from a therapist to walk even with grasping parallel bars because he could not hyperextend the right knee and the knee had collapsed. For physical therapy, he performed stretching, muscle strengthening, standing, and walking exercises. Consequently, he was able to walk with a walking frame independently at discharge (day 131 after the onset). He regained knee hyperextension and resolved the knee collapse. MMT for the right hip muscles became Poor. This hemiparetic stroke patient with polio had severe right leg palsy and consequently had trouble walking due to knee collapse. It is postulated that regaining the knee hyperextension enabled him to walk safely.

The Trail Making Test (TMT) is widely used as a measure of attention impairment. The time needed to complete TMT (TMT score) is prolonged in association with attention impairment in patients with brain diseases. Thus far, however, there have been no reports of serial changes in the TMT score after minor ischemic stroke. We retrospectively investigated serial changes in the TMT score of 19 patients with minor ischemic stroke. We included patients in whom TMT could be performed both 4-11 days after onset (initial evaluation) and 14-47 days after onset (second evaluation). The mean value of the initial TMT-A scores was 58 seconds, and that of the initial TMT-B scores was 144 seconds. The mean value of the second TMT-A scores was 43 seconds, and that of the second TMT-B scores was 119 seconds. The TMT-A and TMT-B scores improved in 89 % and 74 % of patients, respectively. This study demonstrated that most minor ischemic stroke patients showed improvement in the TMT score 14 days or later after onset.

The function of the insular cortex (IC) in humans is poorly understood because brain injuries with a focal lesion in this area are extremely rare. Here, we compare the clinical presentation of two patients with cerebral infarction with major lesions in the left anterior and right posterior IC, respectively, and discuss the functions of these areas. Patient 1 (man in his 70s; cerebral infarctions in the left anterior IC, left inferior frontal gyrus, and dorsolateral left frontal lobe) did not show any motor or sensory function deficit. He presented with transient aphasia and global attention dysfunction that persisted for 3 months after onset, but he was able to return to work and resume driving. Patient 2 (woman in her 60s; cerebral infarctions in the right posterior IC, right supramarginal gyrus, and right parieto-occipital subcortical) presented with transient motor paralysis of the left side of the face and left upper limb and hypoalgesia of the left upper and lower limb. She showed decreased stereognostic sense in the left hand and disturbances in taste, olfaction, and interoception. The different clinical presentations of these two patients suggest that the anterior and posterior areas of the IC have different functions: the anterior area is mainly involved in cognitive functions, whereas the posterior area is mainly involved in sensorimotor functions. Our patients did not have focal lesion of the IC, and more cases need to be evaluated to reveal the IC’s function in humans.

The relationship quality between therapists and clients is crucial for obtaining a good outcome from long-term therapeutic relationships such as counseling and physical/occupational therapy. Although findings on the relationship between the compatibility of therapists and clients and their self-reported psychological characteristics/behaviors have been accumulated, it has been suggested that the compatibility of interpersonal relationships cannot be predicted by psychological constructs. Recently, using resting-state functional magnetic resonance imaging (fMRI) data and a newly developed similarity index, we overcame the limitations of self-report psychological constructs and succeeded in predicting the compatibility of interpersonal relationships a priori. We propose a procedure to predict therapist-client compatibility for better therapeutic outcomes. We hope that this tutorial note will promote the development of a prediction system and help make it more practical in the near future.

Right-sided unilateral spatial neglect (USN) of patients with left hemisphere stroke disappears within a few months from the onset. Also, it has been reported that right-sided USN of bilateral hemisphere lesions patients persists even after 6 months from the onset. Herein, we present the case of a left middle cerebral artery stroke patient with persistent right-sided USN. The patient was right-handed female in her eighties. She was diagnosed with myelodysplastic syndrome 12 years before and then had severe anemia. She suffered from stroke and was hospitalized. She complained of severe right-sided hemiparesis, sensory disturbance, USN, and aphasia. During hospitalization, the laboratory tests revealed a hemoglobin level of 6.0 – 10.2 g/dL and hematocrit level of 18.3–31.8 %. She underwent rehabilitation for fatigue from the anemia. However, her right-sided hemiparesis and USN persisted, and on day 174 post onset she needed support for activities of daily living. Studies have reported that the persistence of the right-sided USN with left hemisphere lesions have a strong relationship with hypoperfusion in the left hemisphere and right parietal regions, even if the right hemisphere has no lesion at all. The decrease in the bilateral hemisphere function is known to hinder the improvement of right-sided USN. Severe anemia (hematocrit level 21.0 %) has also been reported to decrease the oxygen metabolism of whole brain cortex. From these studies severe anemia was thought to hinder the improvement of right-sided USN.

We report a case of left thalamic hemorrhage with motor paralysis in the right upper and lower extremities, somatosensory dysfunction, right homonymous hemianopsia, decreased spontaneity, and amnestic aphasia five months after onset of hemorrhage. The brain image findings revealed that it was a case of thalamic hemorrhage originating from the thalamic geniculate artery, and the major lesional area was the posterior thalamic region, including the posterolateral ventral nucleus, the median nucleus, part of the dorsal medial nucleus, the lateral ventral nucleus, and the pulvinar. In addition, Parkinson’s-like symptoms were occasionally observed five months after thalamic hemorrhage onset, and these might be associated with a previous right putaminal hemorrhage. Here, we report the clinical course and neuro-imaging findings from the onset of thalamic hemorrhage to five months post-event and discuss the causative factors of each clinical finding.

Abstract: Bilateral infarction of the medial medulla is rare, and few reports have described its prognosis and detailed clinical findings. This case report describes a 40-year-old male patient with bilateral infarction of the medial medulla who underwent rehabilitation and subsequently showed satisfactory improvement in motor function. The patient reported his difficulty in moving his left upper and lower limbs and was then admitted to an acute care hospital the next day. On the second day of hospitalization, high intensity in the bilateral medial medulla was observed in the brain magnetic response (MR) diffusion-weighted images. Rehabilitation was started on this day. Physical therapy assessment was as follows: Brunnstrom recovery stage (BRS), VI-VI-VI/V-V-V (upper-finger-lower, right/left); scale for the assessment and rating of ataxia (SARA), 9 (walking, 3; stance, 2; sitting, 2; finger chase, 0/1; nose-finger test, 0/1; heel-shin test, 0/2 [right/left]); and Functional Independence Measure (FIM), 121. After 15 days, some motor deficits were improved (i.e., SARA, 6.5 [walking, 2; stance, 1; sitting, 2; finger chase, 0/1; nose-finger test, 0/1; heel-shin test, 0/1]; FIM, 124), but not BRS. This showed that this patient still had a mild motor deficit of the trunk and left limbs, despite his independence in activities of daily living except for going up and down the stairs.

Repeated gait training with a flexible knee brace and an oil damper hinged ankle-foot orthosis (GSD, Gaitsolution Design, Kawamura Gishi, Osaka, Japan) improved the gait abnormalities and speed in a stroke patient with ataxic hemiparesis. Here, we report on a female in her 50s with a cerebral infarction in the posterolateral thalamus. She had ataxic hemiparesis in her lower left leg. While walking, her knee was bending at initial contact and loading response due to the ataxic hemiparesis, and her gait speed remained at 52.2 m/min. To reconstruct the inverted pendulum model, we provided gait training with a flexible knee brace and GSD. As a result, her gait abnormalities were resolved and her gait speed improved up to 72.6 m/min. We speculated that the one of the reasons for the improvement in gait speed was the adjustment of the task difficulty to address the gait abnormality due to the ataxic hemiplegia, and repeating gait training with an inverted pendulum model. We concluded that providing repeated gait training with a flexible knee brace and GSD to construct the inverted pendulum model may improve the gait abnormalities and speed in patients with ataxic hemiparesis.

Motor impairment following stroke is one of the most important issues to be addressed in clinical care. In this review, we summarize a study in which lost volitional motor control of the hand was regained in a monkey model of stroke using an “artificial cortico-muscular connection” (ACMC) via a neural interface that bypassed the damaged neural pathway after stroke. The ACMC was produced by a computer interface that can detect the high-gamma cortical oscillations and converted in real-time to activity-contingent electrical stimuli delivered to the paralyzed muscles. As a result, within 20 min, the monkeys learned rapidly to use the ACMC and reacquired volitional motor control of the affected hand. Learning to use the ACMC was achieved regardless of whether the input signal was extracted from the primary motor area or the primary somatosensory area, and the activation areas of the input high-gamma signals were changed to concentrate around the arbitrarily-assigned input electrode as learning progressed. This study may have the potential to lead to the development of a clinically effective neural prosthesis to regain lost motor function by bypassing the lesion site and activating paralyzed muscles via an artificial neural connection, even after a limb is paralyzed due to stroke.
