![]() showed that using an individualized sleep system, in comparison with the sleep system which an individual usually uses, causes the shoulder and back pain of the individual to decrease and his sleep quality to increase. observed that patients with low back pain feel less comfortable on a mattress with high stiffness than on a mattress with average stiffness. Thereagainst, mattresses with high stiffness lead to shoulder pain, and cause the decrease in sleep quality and improper distribution of body loads. Soft surfaces cause the increase in low back pain due to incorrect support of vertebral column. The effect of these parameters on the soundness of vertebral column has been also investigated. Various researches have been done on the effect of mechanical parameters of sleep system (cushion, mattress, bed base) on the posture of individual, manner of load distribution, decubitus ulcer, temperature and heat transfer, comfort, and physiological responses of the body like muscle relaxation. With the change of the direction of gravity vector during sleep, the intervertebral disks are unloaded and can rehydrate to restore their elasticity. Growth and restoration of intervertebral disks as a hydrated soft tissue are based on the amount of pressure and its manner of application on them. A non-neutral posture can apply lateral bending and unbalanced loading on intervertebral disks and facet joints. A proper sleep system can align the spine to some extent in its neutral posture which is the same as the spine alignment in upright position. Human being has no active control on spine alignment during sleep. Observing the amount of required stiffness obtained for the sleep surface, can have a significant effect on keeping the spine healthy. ![]() After data fitting, it was observed that the variations of spinal alignment obtained from both methods have the same trend. The mattress with a custom-made arrangement is a more appropriate choice for heavier men with pronounced body contour. In modeling part, the required stiffness of the sleep surface for four weight-dimensional groups was acquired quantitatively. The one way ANOVA statistical model and the post hoc tests showed a significant difference in the π-P 8 angles between soft & custom-made and soft & firm mattresses at the p = 0.001 level and between firm & soft mattresses at the p = 0.05 level. 2007, Biomechanics Research Group, Inc., USA) based on these data and in accordance with the experimental tests, were analyzed. And then the models built in BRG.LifeMOD (ver. In modeling part the anthropometric data of four different types of volunteers were used. Thereupon the π-P 8 angles were extracted from these alignments and then were compared with each other. In experimental part, the coordinate positions of the markers mounted on the spinous processes of the vertebrae of 25 male volunteers were registered in frontal plane through the optical tracking method and so the spinal alignment was obtained in lateral sleep position on soft and firm surfaces and on the best custom-made arrangement. The required stiffness of a sleep surface for each individual can be obtained by changing this arrangement applying the experimental method and modeling. To keep the spine in optimal alignment, one can use sleep surfaces with different zonal elasticity, the so called custom-made arrangements. Most of the previous studies in scientific literature have focused on the effects of customary mattresses on the spinal alignment.
