Objective：Brain disorders are major concerns in rehabilitation medicine in Japan. Of the various categories of brain disorders, rehabilitative treatments for strokes, traumatic brain injuries, and neurodegenerative diseases are different. This study aimed to demonstrate the specificities of the rehabilitative treatments for these three subcategories after statistical analysis of textual data from abstracts indexed during an annual meeting for rehabilitation medicine.

Materials and Methods：Abstracts indexed during the 56^th annual meeting of the Japanese Association of Rehabilitation Medicine in 2019 were entered into the analytical database. Words associated with each subcategory were extracted using Jaccard's similarity coefficients.

Results：The analysies showed that the words strongly associated with strokes were “paresis,” “convalescent,” “admission,” “onset,” “ward,” “function,” “FIM,” “impairment,” “improvement,” and “discharge” (extracted from 402 abstracts；coefficients ranged from 0.36 to 0.23). In parallel, the words such as “trauma,” “traffic,” “higher,” “accident,” “fall,” “brain,” “labor,” “brain-disease,” “hematoma,” and “facility” were related to traumatic brain injuries (extracted from 36 abstracts；coefficients ranged from 0.15 to 0.08). The words strongly associated with neurodegenerative diseases were “cognition,” “MMSE,” “elderly,” “care,” “home,” “nursing home,” “fracture,” “impairment,” “Yahr,” and “disease” (extracted from 96 abstracts；coefficients ranged from 0.18 to 0.09).

Conclusions：The specifics of rehabilitative treatments for strokes, traumatic brain injuries, and neurodegenerative diseases were successfully outlined after the analysies of the textual data. This technique may be useful for evaluating information provided in textual forms, such as abstracts of conferences.

Objective：The purpose of this study was to evaluate the effectiveness of a four-week short-term intensive rehabilitation on ataxia in patients with ambulatory spinocerebellar degeneration (SCD), using the Scale for the Assessment and Rating of Ataxia (SARA) total score and sub-score.

Methods：This study included 23 SCD patients；we considered those with a SARA gait score of＜3 points. Our program included a one-hour training session with individualized instructions and a one-hour self-balance training session. Additionally, occupational or speech-language-hearing therapy was performed for one hour daily. Our program was conducted five days weekly for four weeks. We assessed the SARA total score and sub-score findings immediately, before the first and after the last interventions.

Results：The SARA total, gait, stance, and heel-shin scores showed more significant improvement after intervention than before intervention (p＜0.05). The other SARA sub-scores were not significantly different between “before and after” interventions.

Conclusion：The four-week short-term intensive rehabilitation on ataxia in patients with ambulatory spinocerebellar degeneration improved the SARA total score and ataxia of the trunk and lower limbs.

Fat embolism syndrome (FES) is a serious complication of orthopedic surgery. We describe a woman in her 30s, who experienced cerebral FES after extensive femoral tumor resection and intercalary endoprosthesis for a malignant soft tissue tumor of the thigh. Before the surgery, the patient was able to walk with a single axillary crutch, capable of independent self-care and had no cognitive problems. After the surgery, the patient developed respiratory and central nervous system symptoms, which are characteristic of FES. After critical care, we provided rehabilitation treatment, which included getting out of bed, basic motion training, cognitive rehabilitation treatment, and Activity of Daily Living (ADL) training. At the time of commencement of the rehabilitation treatment, the patient presented with higher brain dysfunctions, such as cognitive dysfunction (Mini Mental State Examination：MMSE score 21 points), attentional dysfunction and left unilateral spatial neglect (USN). However, apparent motor paralysis of the extremities was not detected. On the 95^th day after the surgery, the patient's MMSE score was 29 points, and the attentional dysfunction and USN were resolved. Additionally, the patient was again able to walk with axillary crutch. Six months after the surgery, the patient could walk independently without the aid of a crutch. One year after the surgery, the patient's reinstated to work. Cerebral FES may be accompanied with higher brain dysfunction；present a variety of higher brain dysfunctions；however, the symptoms may be reversible and resolved with rehabilitation treatment.
