Brief Summary:
Sleep quantity and quality can be influenced by the type of mattress used. This study is being done to see if a mattress cover with optically active particles can help back pain and improve sleep quality.

Condition or disease Intervention/treatment Phase
Back Pain Insomnia Device: Active Mattress Cover Device: Placebo Mattress Cover Not Applicable

Detailed Description:
It is commonly observed that sleep in its quantity and quality is influenced by the type of mattress used at night. A recent study in patients with back pain showed that waterbeds and foam mattresses did influence back symptoms, function and sleep more positively than did a hard mattress. Pain improves with airbeds compared to regular innerspring mattresses. This study will analyze the effect of optically active particles mattress covers on sleep. The researcher is interested in learning if regular mattress or the study mattress cover (containing optically modified polyethylene terephthalate fiber mattress cover) is more useful in helping back pain and sleep quality.

Outcome Measures

Primary Outcome Measures :
  1. Optically Modified Polyethylene Terephthalate Fiber Mattress Cover (OMPETFMC) Improves Sleep Quality in Patients With Lower Back Pain as Measured by Clinical Global Impression (CGI). [ Time Frame: 14 days ]

    The primary outcomes are the change in mean daily Clinical Global Impressions (pain and sleep) in placebo mattress compared to active mattress cover (assessed daily for 14 days per intervention).

    The daily scores range from 1 (very much improved) to 7 (very much worse).



Secondary Outcome Measures :
  1. Sleep Variables (Nighttime Wake-time) Measured With Actigraphy in Patients With Lower Back Pain. [ Time Frame: Assessed daily for 14 days per intervention. ]
    Secondary outcome: Nighttime wake-time after sleep onset with placebo mattress cover compared to active mattress cover.

  2. Sleep Variables (Total Sleep) Measured With Actigraphy in Patients With Lower Back Pain. [ Time Frame: Assessed daily for 14 days per intervention. ]
    Secondary outcome: Total sleep time with placebo mattress cover compared to active mattress cover.

  3. Sleep Variables (Nocturnal Awakenings) Measured With Actigraphy in Patients With Lower Back Pain. [ Time Frame: Assessed daily for 14 days per intervention. ]
    Secondary outcome: Number of nocturnal awakenings with placebo mattress cover compared to active mattress cover.

  4. Sleep Variables (Sleep Efficiency) Measured With Actigraphy in Patients With Lower Back Pain. [ Time Frame: Assessed daily for 14 days per intervention. ]
    Secondary outcome: Sleep efficiency in placebo mattress cover compared to active mattress cover.

  5. Sleep Variables (Sleep Latency) Measured With Actigraphy in Patients With Lower Back Pain. [ Time Frame: Assessed daily for 14 days per intervention. ]
    Secondary outcome: Sleep latency in placebo mattress cover compared to active mattress cover.

  7. are currently participate or participated in another clinical study within the past 30 days
  8. demonstrate an unwillingness to comply with the maximum limit of two alcoholic drinks per day and only 1 alcoholic drink after 6:00 P.M. for the duration of the protocol
  9. use tobacco products or any other products during nightly awakenings that may interfere with the sleep wake cycle
  10. have any unstable medical condition as determined by the investigator, or any other serious disease or condition that might affect life expectancy or make it difficult to successfully manage and follow the subject according to the protocol
