Outcome Measures

Primary Outcome Measures :
  1. Change in pain ratings from before to after brief blanket use [ Time Frame: 0 and 15 minutes ]
    Pain ratings will be compared before and after use of weighted blanket on the following scale: Pain VAS: "No pain" to "Worst pain ever" (higher = worse).

  2. Change in pain ratings from before to after nightly blanket use [ Time Frame: at baseline (3 nights) and over 7 nights of use ]
    Pain ratings will be compared before and after 1 week of nightly use of weighted blanket on the following scale: Pain VAS: "No pain" to "Worst pain ever" (higher = worse).


Secondary Outcome Measures :
  1. Change in anxiety ratings from before to after brief blanket use [ Time Frame: 0 and 15 minutes; also at baseline (3 nights) and over 7 nights of use ]
    Anxiety ratings will be compared before and after use of weighted blanket on the following scale: Anxiety VAS: "Extremely anxious" to "Neutral" to "Extremely calm" (higher = better).

  2. Change in ratings of sleep quality from before to after brief blanket use [ Time Frame: baseline (3 nights) and over 7 nights of use ]
    Change in sleep quality from before to after use of weighted blanket will be compared on the following scale: perceived sleep quality VAS: "Extremely poor" to "Neutral" to "Extremely good" (higher = better).

  3. Change in sleep quality measured by fitness watch from before to during week of blanket use [ Time Frame: baseline (3 nights) and over 7 nights of use ]
    Change in sleep quality from before to during use of weighted blanket will be compared by measurement of deep vs light sleep from a fitness watch.
