  "account": "Vibrotactile stimulation on the upper back proves effective for goal-directed reaching tasks, despite slightly heightened tactile suppression and mental workload, according to a recent study. Participants engaged in detection, reaching, and reach-and-detect tasks, with vibrotactile signals applied either on the hand or upper back. While sensitivity to stimuli was reduced during movement, this suppression was more pronounced for hand stimulation compared to upper back stimulation. Movement time was lengthened when vibration was applied to the hand but remained unaffected by upper back stimulation. Task complexity and mental workload also rose for the reach-and-detect task compared to the isolated tasks. The study concludes that vibrotactile feedback devices worn on the upper back do not hinder motor performance, with only minor tactile suppression potentially mitigated by highly distinctive or personalized feedback.",
  "summary": "Vibrotactile stimulation is a promising method of biofeedback, with potential applications for ergonomic posture and balance, rehabilitation, and motor learning. These applications require balancing tactile perception with motor performance and cognitive workload. In this study, participants performed a detection task, a reaching task, and a concurrent reach-and-detect task, with vibrotactile…",
