In recent years, there has been much research and development of wearable devices using accelerometers for studying physical activity. Previously, we have described the development of the Posture and Activity Detector (PAD). After demonstrating success with PAD, we were motivated to improve the design by taking the device one step further and implementing all of these components on a single printed circuit board, adding a few additional features to make the system more flexible, and custom-designing an outer case. We have continued our efforts in improving PAD with respect to software development as well as making PAD more physically robust and mass producible. In this paper, the specifications for PAD will be outlined including its hardware and software components, and clinical research applications.

Vestibular dysfunction has been reported as a potential cause in adolescent idiopathic scoliosis (AIS). However, it remained unclear how stochastic galvanic vestibular stimulation (GVS) affected kinetic performance of patients with AIS. This study aimed to investigate the effect of stochastic GVS on ground reaction forces (GRF) measures during obstacle negotiation among patients with AIS.

Improving physical balance among older workers is essential for preventing falls in workplace. We aimed to elucidate the age-related decline in one-leg standing time with eyes closed, an indicator of static balance, and mitigating influence of daily walking habits on this decline in Japan. This longitudinal study involved 249 manufacturing workers, including seven females, aged 20-66 years engaged in tasks performed at height in the aircraft and spacecraft machinery industry.

Prolonged sitting can negatively impact postprandial glucose levels and cognitive function. While short bouts of stair climbing are thought to mitigate these risks, the findings remain inconclusive. The present study aimed to explore the effects of stair climbing bouts on postprandial glucose and cognitive functions during prolonged sitting.

Background: There is growing literature examining the effects of balance training on cognitive function in individuals with multiple sclerosis (MS), yet the findings remain inconsistent. This study aimed to investigate methodological characteristics of balance training studies and examine the effects of this modality on cognitive function.
Methods: This study performed literature search using MEDLINE, EMBASE, PsycINFO, SPORTSDiscus, and CINAHL databases from inception to April 2024.
