Perceived heaviness of a weight lifted by flexion of the distal joint of one digit increases when an adjacent digit concurrently lifts a weight. The present study confirmed this finding for relatively low weights (representing 3-5% maximal voluntary force) and a method was adapted to show that this effect occurs for much larger weights (20-25% maximal force). Thus, the increase in perceived heaviness is likely to operate over a wide range of muscle force generated by the hand. As perceived heaviness is biased by the magnitude of the central motor commands, these findings may reflect a lack of complete independence of motor commands to the long flexor muscles acting on the digits.

Exoskeletons are used in rehabilitation centers for people with spinal cord injuries (SCI) due to the potential benefits they offer for locomotor rehabilitation. The acceptability of exoskeletons is crucial to promote rehabilitation and to ensure a successful implementation of this technology. The objective was to explore the acceptability of overground wearable powered exoskeleton used in rehabilitation among people with SCI.

This study aims to explore the relationship between perceived limb heaviness and return to work (RTW) among ischemic stroke patients. We retrospectively reviewed the data of consecutive participants recruited in the CIRCLE study. Perceived limb heaviness was gathered from self-reported by 1-year follow-up.

Smoking prevalence remains high in Europe and widening socioeconomic group differences are driving health inequalities. While plain packaging policies disrupt tobacco industry tactics that sustain smoking, evidence of their equity impact is sparse. This study evaluated the implementation of plain packaging in Ireland in 2018 on consumer responses, overall and by the socioeconomic group.

In recent years, due to the prevalence of virtual reality (VR) and human-computer interaction (HCI) research, along with the expectation that understanding the process of establishing sense of ownership, sense of agency, and limb heaviness (in this study, limb heaviness is replaced with comfort level) will contribute to the development of various medical rehabilitation, various studies have been actively conducted in these fields. Previous studies have indicated that each perceptual characteristics decrease in response to positive delay. However, it is still unclear how each perceptual characteristic changes in response to negative delay.
