Age differences in the variability and distribution of sleep spindle and rapid eye movement densities. by Kevin R Peters, Laura B Ray, Stuart Fogel, Valerie Smith, Carlyle T Smith

“…Although age differences were observed in the degree of absolute variability (older adults had significantly larger variances than young adults for sleep efficiency and time spent awake after sleep onset), a similar pattern was also observed within the two age groups: the four sleep measures with the lowest degrees of relative variability were the same and included time spent in REM and Stage 2 sleep, total sleep time, and sleep efficiency. …”

A Home-Based Self-Powered Rehabilitation System With Variable Stiffness Mechanism by Ke Shi, Yingchen Gao, Maozeng Zhang, Lifeng Zhu, Aiguo Song

“…However, the lack of real-time therapist supervision requires higher safety, ease of use, and training efficiency of the rehabilitation system. Therefore, active robot rehabilitation systems may not be particularly ideal for home use due to high costs, large footprints, safety concerns, and the potential for motor slacking. …”
