Objective: The purpose of this study was to examine how rehabilitation and patient education for knee osteoarthritis improves health-related quality of life (HRQOL) and to identify factors influencing HRQOL. Methods: Between May 2020 and March 2022, 30 patients with osteoarthritis of the knee were treated conservatively and rehabilitated with a patient education program. The patient education program was based on the health belief model by Sedlak et al., and patient education using pamphlets was provided during the rehabilitation intervention. The survey items were patient basic information, instrumental activities of daily living (ADL) (FAI), fear of falling (FES), degree of depression (GDS), HRQOL (SF-8), knee function assessment (JOA score), and X-ray classification (K-L classification), and the survey method was a self-administered questionnaire at the start of rehabilitation, 1 month after the intervention, and at the end of the rehabilitation intervention. We examined factors affecting the physical component summary (PCS) and mental component summary (MCS) of HRQOL scores. Results: JOA score, FES, FAI, GDS, and SF-8 improved significantly (p<0.01). MCS was also negatively correlated with FES and age (r=-0.486, -0.368). Sex was extracted as a factor for PCS as a factor affecting HRQOL (p<0.01). MCS was extracted with FES as a factor (p=0.046). Conclusion A rehabilitation intervention incorporating patient education in osteoarthritis of the knee showed improvement in HRQOL and may be useful for improving depression, fear of falling, and instrumental ADL.

Objective: In older patients, dysphagia is a major risk factor for aspiration pneumonia and choking as it progresses slowly and recurs repeatedly without awareness. Information and communication technology (ICT) is used in various medical fields. However, no feeding or swallowing disorder prevention program has been developed to date and no reports have verified its effectiveness and safety. This study aimed to develop a dysphagia rehabilitation system using ICT and verify its effectiveness.Methods: Changes in swallowing function and functional prognosis were examined in 120 patients with aspiration pneumonia: 60 in the control and 60 in the ICT group. Physical therapists performed pulmonary rehabilitation in the control group. There were additional activities within the ICT rehabilitation system, such as motor and swallowing function evaluations, training sessions, and provision of dietary instructions, in addition to the rehabilitation content of the control group.Results: The Functional Oral Intake Scale (FOIS) score, a measure of swallowing function, significantly improved in the ICT group (P<0.001). ICT use was considered an influencing factor of FOIS change (β=0.49, 95% confidence interval, 1.47 to 2.97 P<0.001). ICT use positively affected the Barthel index gain (β=0.49, 95% confidence interval, 14.73 to 32.72 P<0.001).Conclusion: A rehabilitation program using ICT improved swallowing function and the Barthel index. The system can also be used in sparsely populated and rural areas where there are few rehabilitation professionals, and high ripple effects are expected.

Objective: Dysphagia rehabilitation is an important area in geriatric nutrition due to the commonality of sarcopenic dysphagia in older adults. However, there have been no reports on the efficacy of treatment by board-certified physiatrists (BCP) in patients with sarcopenic dysphagia. This study therefore aimed to investigate whether intervention by board-certified physiatrists affects the functional prognosis of patients with sarcopenic dysphagia.Materials and Methods: Of 467 patients enrolled in the Japanese Sarcopenic Dysphagia database between November 2019 and March 2021, 433 met the study eligibility criteria. The patients were divided into two groups based on whether or not they received intervention by a BCP. The clinical characteristics and outcomes of the two groups were compared. Statistical analyses were performed by inverse probability weighting (IPW).Results: BCPs were involved in the management of 57.0% of patients with sarcopenic dysphagia. These patients had a significantly higher increase in the Barthel index both before and after IPW correction than those not managed by a BCP (P=0.001 and P=0.016, respectively). However, sarcopenic dysphagia significantly improved in the non-BCP group before IPW correction (P<0.001), although there was no significant difference after IPW correction (P=0.301).Conclusion: BCP management was significantly associated with higher activities of daily living (ADL), but not with an improvement in sarcopenic dysphagia. To provide and manage effective rehabilitation, it is necessary to familiarize patients with the management and training of sarcopenic dysphagia rehabilitation for BCP in order to cope in regions with few rehabilitation units.
