In this study, we examined the effectiveness of rehabilitation for chronic pain patients affected by weather changes, evaluated by subjective sensory scales. Subjective sensory scale questionnaires were assessed at the first and follow-up visits. Pain intensity scale, pain disability assessment scale, and pain catastrophizing scale were improved in both pharmacotherapy alone group and combined with rehabilitation therapy group. Furthermore, in the rehabilitation combined therapy group, decrease of anxiety and depression scale, and improvement of self-efficacy were also observed. These findings suggest that combined rehabilitation therapy has advantages over pharmacotherapy alone in chronic pain patients associated with weather changes.
The purpose of this study is clarifying the regional and meteorological characteristics of weather-related pain in Japan. Symptom data was made from reports which Weathernews’ smartphone application users had sent since June 2020.Totally 434,409 symptom data in the period from 1st June 2020 to 31st December 2022 was collected to evaluate susceptibility of weather-related pain in 47 prefectures. Also three types of pressure indexes, each having different wave cycles: micro-pressure fluctuation (MPF), synoptic scale low pressure impact, and semidiurnal atmospheric tide, were made to research relevance between weather-related pain and the types of pressure indexes.
These data revealed that two out of three pressure indexes marked high scores in Yamagata and Yamanashi prefectures, and these prefectures also marked high scores of weather-related pain suffered index.
Exercise performance is modulated by various factors, such as physical, environmental, and mental factors. Therefore, during exercise, the brain is continuously planning exercise strategies. The purpose of this study was to assess the brain activity associated with instantaneous exercise strategies using electroencephalographic event-related potentials (ERPs) and transcranial Doppler sonography (TCD). Eleven young volunteers performed three different workloads of isometric handgrip exercises with and without a warning stimulus (STM and WPM, respectively). The contingent negative variation (CNV) and mean middle cerebral artery blood velocity (MCAVmean) were evaluated by ERPs and TCD, respectively. The warning stimulus induced CNV and increased MCAVmean before the start of exercise. The increase in MCAVmean was greater at higher exercise intensity, but the amplitude of CNV didn't change. The amplitudes of CNV and MCAVmean were similar between tasks of different difficulty levels. These findings suggest that MCAVmean measured with TCD could evaluate minute change of brain activity associated with movement strategies.
