Cross-sectional study of different mattresses, lumbar back muscle activity, and autonomic nervous system function

To clarify the impact of different mattresses on motor and neurological functions, lumbar muscle activity and autonomic functions were compared in 16 healthy subjects lying on two mattresses: a common market type (Mattress A) and our custom-developed one (Mattress B). Surface electromyography of the dorsal lumbar muscles and an autonomic function were recorded in 16 healthy subjects in the supine position on two types of mattresses: one generally available on the market (Mattress A) and another developed by our team (Mattress B). Results showed significantly lower lumbar muscle activity and a trend towards parasympathetic dominance on Mattress B. However, the study didn't account for mechanical effects, personal preferences, or body size. The results of this study suggest that mattresses can affect lumbar muscle activity and autonomic function. Further research may help manage back pain and stress related to bedding.
