Chitosan Phonophresis on Cervical IN Smartphone Addicted Users

Effect of Chitosan Phonophresis on Cervical Pain and Disability in Smartphone Addicted Users

A phonophoresis-based drug delivery system is a synchronous approach to improve local drug penetration in neuromuscular diseases associated with neuronal damage, excruciating pain, and local inflammation. Chitosan, a semi-synthetic material, is obtained by partial deacetylation of chitin amines, resulting in copolymers of N-acetylglucosamine and N-glucosamine. Its use has been explored in various biomaterial and medical applications. Chitosan has emerged as a cost-effective, biocompatible, and biodegradable material with many desirable biological properties, improvement of homeostasis and antiviral potential. Chitosan was found to suppress pro-inflammatory cytokines and decreased peripheral nerve edema, the polycationic nature of chitosan allows it to absorb protons, which reduces inflammation and provides an analgesic effect.
