Objective: Back pain is one of the major problems of today's societies. Chronic back pains wich lasts more than 3 months and there is no specific anatomical or pathological cause for them, include a high percentage of back pains. In these patients, the sense of proprioception decreases, which can increase pain and complicate the problem. In this study, the method of making belts with textured pads that increases the sense of proprioception by stimulating the sense of touch is presented.
Method: In this study, a 48-year-old female patient with chronic low back pain which was started 4 years ago referred to Imam Reza educational and therapeutic clinic in Shiraz and used the neoprene belt with silicone pad which was made in this study, for 6 weeks and 8 hours a day at least. The patient's pain and functional disability was measured by visual analog scale and oswestry disability index before using the belt and after 6 weeks of using it, and her satisfaction with the treatment method was recorded. To make the belt, first a plaster mold was prepared in the shape of a triangle made of hemihydrated calcium sulfate gypsum and holes were inserted in it with marked drill to create fluff, and then the created hole was filled with RTV sanitary silicone. Finally, the silicone pad was connected to the neoprene belt. The force applied by the belt was equal to 50 newtons, which was measured by a dynamometer, and the correct closing location was marked on the belt based on this force. A notebook with dated pages was provided to the patient and she was asked to write down the hours of belt use and total daily hours in it.
Findings: At the beginning of the study, according to patient's claim, her back pain was equal to 6 with the numerical visual index, and at the end of the study, it reached 2 and decreased. Also, the score recorded based on Oswestry Disability Questionnaire before using the belt was 25, and after 6 weeks of using the belt, it decreased significantly and reached 11.  The patient was satisfied with the treatment method used. She had gradually increased the use of the belt due to its positive effects.Result: The use of textured pad in neoprene belts has a positive role in reducing pain and increasing the ability of patient, and if confirmed in wider studies, it can help improve these patients as a prefabricated orthosis.
