Trial on the Effect of Optically Modified Fiber Mattress Covers on Sleep Disturbances in Patients With Chronic Back Pain

Not Applicable

Completed

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.

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.

Recruitment & Eligibility

Inclusion Criteria

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.

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

Arm && Interventions

Group	Intervention	Description
Placebo Mattress Cover	Placebo Mattress Cover	Subjects in this arm will be given the active mattress cover followed by the placebo mattress cover.
Active Mattress Cover	Active Mattress Cover	Subjects in this arm will be given the placebo mattress cover followed active mattress cover .

Primary Outcome Measures

Name	Time	Method
Optically Modified Polyethylene Terephthalate Fiber Mattress Cover (OMPETFMC) Improves Sleep Quality in Patients With Lower Back Pain as Measured by Clinical Global Impression (CGI).	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

Name	Time	Method
Sleep Variables (Sleep Latency) Measured With Actigraphy in Patients With Lower Back Pain.	Assessed daily for 14 days per intervention.	Secondary outcome: Sleep latency in placebo mattress cover compared to active mattress cover.
Sleep Variables (Nighttime Wake-time) Measured With Actigraphy in Patients With Lower Back Pain.	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.	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.	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.	Assessed daily for 14 days per intervention.	Secondary outcome: Sleep efficiency in placebo mattress cover compared to active mattress cover.
