Prospective study of application of biological communication (cybernatics) in management of chronic low back pain--a preliminary report.

To observe the effects of application of cybernetics (theories of communication). This is an open level prospective study, involving patients with chronic low back pain of more than 3 months. Assessment were done before the start of therapy and after the completion of therapy every day for consecutive 6 days of treatment protocol. A total of 8 patients were enrolled (4 male, 4 female). The Visual Analogue Scale (VAS) was used to assess pain, Oswestry Disability Scale (ODI) was applied for scoring disability. ODI was scored at the start of treatment on 1st day and at the end of the treatment on 6th day. Mean VAS reduced from 8.12 to 6.93 after 1st day, which was also statistically significant (p < .01) .This trend continued and there was very significant reduction (p < .001) of VAS in the end when means were compared with pretreatment value. Mean Oswestry disability index reduced from 49.875 to 18.44 at the end of treatment which was statistically very significant (p < 0.001). There were significant improvements in all the outcome measured after Scrambler therapy.

A green Hunsdiecker reaction: synthesis of beta-bromostyrenes from the reaction of alpha,beta-unsaturated aromatic carboxylic acids with KBr and H2O2 catalysed by Na2MoO4.2H2O in aqueous medium.

Reaction of alpha,beta-unsaturated aromatic carboxylic acids with KBr and H2O2 in the presence of Na2MoO4.2H2O in aqueous medium affords beta-bromo alkenes in high yield.
