With literature research the hypothesis, that 70% of the evidenced based studies about drug application by phonophoresis describes this modality as possible, and the hypothesis, that 70% of the evidenced based studies about phonophoresis as a therapy for musculoskeletal disorders is shown to increase the function and to reduce the pain symptomatology, will be proven or disproven.
To be able to objectively evaluate most of the evidence-based studies included in this project and to be able to put them into the correct class of evidence, one should take advantage of SANTESSO´s et al. (2006) assessment criteria. The 70% is a self-chosen limit.
Because of the positive impact of therapeutic ultrasound, based on the mechanical and thermal effects, on the healing of musculoskeletal disorders it is used in the physical medicine.
The phonophoresis, as a combination of drug application and therapeutic ultrasound, is already used by physiotherapists as a treatment for musculoskeletal disorders, though the mechanism of the phonophoresis is not completely understood yet. Musculoskeletal disorders contain all pathological conditions of bones, joints, muscles, tendons and ligaments. The disorders are diagnosed by clinical examination and imaging diagnostics. The main symptom of musculoskeletal disorders is pain, many patients also suffers from decreased range of motion and stiffness of joints.
