This study explores the hypothesis that a high degree of sustained muscle activity associated with a sub-optimal spinal orientation may compromise an individual's ability to relax or initiate sleep. Data from 22 participants who were considered to be part of a normal, back-pain-free population were used in these studies. Participants laid down on a mattress in a foetal position (i.e. on their sides) at three varying bed pressures while EMG activities, heart rates, blood pressures, subjective… Expand

Topics from this paper

Effects of mattress firmness on infant body pressure distribution
TLDR
There is significant correlation between the body pressure indices and the mattress firmness in the supine posture, and the average pressure has the strongest correlation with mattress Firmness. Expand
Ergonomics in bed design: the effect of spinal alignment on sleep parameters
TLDR
Results indicate that a sagging sleep system negatively affects sleep quality for people sleeping in a prone or lateral posture, finding that the relationship between bedding and sleep quality is affected by individual anthropometry and sleep posture. Expand
The Effect of Bedding System Selected by Manual Muscle Testing on Sleep-Related Cardiovascular Functions
TLDR
Heart rate variability and arterial pressure variability analyses showed that the strong bedding system resulted in decreased cardiovascular sympathetic modulation, increased cardiac vagal activity, and increased baroreceptor reflex sensitivity during sleep as compared to the weak beddingSystem. Expand
Spine alignment in men during lateral sleep position: experimental study and modeling
TLDR
The mattress with a custom-made arrangement is a more appropriate choice for heavier men with pronounced body contour after observing the amount of required stiffness obtained for the sleep surface, can have a significant effect on keeping the spine healthy. Expand
Analysis of Human Body Suitability for Mattresses by Using the Level of PsychoPhysiological Relaxation and Development of Regression Model
Objective: The purpose of this study is to find the level of physical relaxation of individual subject by monitoring psychophysiological biofeedback to different types of mattresses. And, the studyExpand
Effects of bedding systems selected by manual muscle testing on sleep and sleep-related respiratory disturbances.
TLDR
It was concluded that MMT can be performed by inexperienced testers for the selection of bedding systems and differences were observed between the strong and the weak bedding system with regard to sleep-related respiratory disturbances and the percentage of slow-wave sleep. Expand
Subjective rating of perceived back pain, stiffness and sleep quality following introduction of medium-firm bedding systems.
TLDR
Similar significant benefits of new, medium- firm bedding systems can occur for those reporting both good and poor current sleep quality and variables such as age, weight, height, and body mass index are independent of such improvements. Expand
Effect of prescribed sleep surfaces on back pain and sleep quality in patients diagnosed with low back and shoulder pain.
TLDR
It was concluded that sleep surfaces are related to sleep discomfort and that it is indeed possible to reduce pain and discomfort and to increase sleep quality in those with chronic back pain by replacing mattresses based on sleeping position. Expand
Smart control of spinal alignment through active adjustment of mechanical bed properties during sleep
TLDR
A significant improvement on subjectively perceived sleep quality was demonstrated after sleeping on the actively controlled systems and a significant improvement of spinal alignment during nights with active control of bed properties compared to a reference night without control. Expand
Grouped comparisons of sleep quality for new and personal bedding systems.
TLDR
It was concluded that new bedding systems can significantly improve selected sleep variables and that continuous sleep quality may be dependent on timely replacement of bedding system. Expand

The use of surface EMG power spectral analysis in the evaluation of back muscle function.
TLDR
Greater erector spinae muscle fatigability was associated with both the existence of, and the risk of developing, serious low back pain and possible mechanisms for the association have been advanced. Expand
Classification of Low Back Pain With the Use of Spectral Electromyogram Parameters
TLDR
The use of spectral parameters to classify subjects with low back pain from those without appears to have merit and models based on 60% ofmaximum voluntary contraction demonstrated results comparable with those of previous research using 40% and 80% of maximum voluntary contraction. Expand
The effect of one night's sleep deprivation on temperature, mood, and physical performance in subjects with different amounts of habitual physical activity.
TLDR
The results stress the considerable interindividual variation in the responses to sleep loss and, therefore, the difficulty associated with giving general advice to individuals about work or training capability after sleep loss. Expand

TLDR
The present study indicated that the trunk holding test with the use of EMG power spectral analysis can be a reliable method to measure the fatigue rate of the back muscles if adequate measures are employed to minimize cross-talk. Expand
Back and hip extensor fatigability in chronic low back pain patients and controls.
TLDR
The EMG fatigue analysis results suggest that the gluteus maximus muscles are more fatigable in chronic low back pain patients than in healthy control subjects during a sustained back extension endurance test. Expand

The process of developing laboratory and clinically based protocols and new areas of investigation designed to improve the classification accuracy of paraspinal muscle impairments using procedures other than discriminant analysis are described. Expand
Mattress evaluation--assessment of contact pressure, comfort and discomfort.
TLDR
It seems likely that subjective ratings of mattress comfort are dependent on a wider set of factors than contact pressure alone, a finding reported elsewhere in studies of seating. Expand
Assessment of Spinal Musculature Using Surface Electromyographic Spectral Color Mapping
TLDR
A new method of analysis of electromyogram data from lumbar spinal muscles has allowed discrimination between people with back pain and healthy people, providing direct evidence of a correlation between muscular electrical function, measured by electromyograms, and low back pain. Expand
Spectral electromyographic assessment of back muscles in patients with low back pain undergoing rehabilitation.
TLDR
Findings demonstrate how electromyographic spectral measurements may be used to identify and monitor back muscle impairment in patients undergoing rehabilitation for low back pain. Expand

TLDR
It was found that insomniacs display increased tension/confusion, decreased vigor, personality disturbance, subjective over-estimation of poor sleep, increased body temperature, increased 24-hour whole body metabolic rate, and increased multiple sleep latency test (MSLT) values. Expand
