The Study: Effects of a wearable type lumbosacral support for low back pain among hospital workers: A randomized controlled trial.
- The authors wished to evaluate the effects of a lumbosacral support.
- Low back pain increases medical costs as well as lost work and affects the quality of life.
- Lumbar supports which restrict motion have been used to prevent injuries.
- Patients with a history of prior low back pain are more likely to have new episodes of low back pain.
- 98.81% of the subjects in this study were nurses. Participants had suffered low back pain, of at least a 3 on a scale of 0 to 10, one or more times a week for the last three months.
- The authors evaluated a new type of lumbosacral support.
- The subjects wore a "support with signals of compression on the back by poor posture."
- The subjects wore the support for a period of three months except when they were bathing or sleeping.
- The support is referred to as “spinal underwear” and has a "textile fabric for stimulating the back while in poor posture."
- The authors concluded that, "This lumbar support has a positive effect on reducing low back pain among healthcare workers."
Basically the device stimulates the back when the subject is in a position of poor posture. The device appeared to have a positive effect on reducing low back pain.
I thought this study was very interesting. It seemed to me that the subjects were being taught to maintain better posture by the feedback from the feelings of the textile fibers of the brace. This study appears to once again link posture to symptoms.
