- 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).
- 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.
- 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.
- 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.
- 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.
- 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.

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
You are eligible to participate in this study if you:
- have a clinical diagnosis of chronic lower back pain
- have pain measured on the Visual Analogue scale
- have sleep disturbances at night associated with chronic lower back pain
- are 18 years or older
- sign the written, informed consent form prior to the initiation of any study procedures
- have an habitual bedtime between 8 P.M. and 12 A.M.
- are on a stable pain management regime
Exclusion Criteria:
You are not eligible to participate in this study if you:
- are unwilling or unable to comply with the protocol or scheduled appointments
- are unable to understand the language in which the approved informed consent is written
- have no pain measured on the Visual Analogue scale
- are unable to walk, wheel chair bound or confined to bed
- are deemed by the investigator to be unreliable to wear the actigraphy, to complete the sleep log, to use the provided mattress covers at the proper time, to come to the scheduled visits or to answer questions regarding the subject's condition or medication use
- lack a mobile arm to which to attach an actigraphy.
- are currently participate or participated in another clinical study within the past 30 days
- 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
- use tobacco products or any other products during nightly awakenings that may interfere with the sleep wake cycle
- 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
