Summary

This study evaluates the effects of various types of ultrasound therapy: continuous, pulsed, sham ultrasound and ultrasound combined with electrotherapy in patients with hip osteoarthritis. Beside ultrasound therapy, patients received usual physiotherapy (balneotherapy, exercise and massage) either.

Detailed description

During ultrasound therapy electrical energy is converted into mechanical energy and heat. It has physical, chemical and biologic effects, like thermal effect, micro-massage, increased tissue metabolism, capillary permeability and tissue healing. Continuous or pulsed forms can be applied. As pulsed ultrasound therapy has no thermal effect, greater intensity can be used. It can alleviate acute pain and inflammation. Continuous ultrasound is usually used in chronic musculoskeletal diseases, in case of limitation of joint motion because its thermal effect. Ultrasound can be combined with electrotherapy, when the effects of the two modalities are summed up.

Conditions

• Hip Osteoarthritis
