ABSTRACT

BACKGROUND:

At present, there are some reports regarding the treatment of high-energy shockwave to chronic pain of muscle and born joint, however,the therapeutic effects and mechanism are still uncertain and need further discussion.

OBJECTIVE:

To explore the curative effects, mechanism and clinical application of high energy shockwave to bone joint myofascitis.

DESIGN:

Non-randomized case controlled study based on diagnosis

SETTING:

Rehabilitation Medicine Department of First Affiliated Hospital of Sun Yat-sen University.

PARTICIPANTS:

Totally 90 patients with chronic pain of muscle and bone joint treated in Rehabilitation Medicine Department of First Affiliated Hospital of Sun Yat-sen University from July 2001 to April 2002 were divided into treatment group and control group each with 45 cases by the order of visiting time. There were 17 males and 28 females in the treatment group with mean age of 54 years and 15 males and 30 females in the control group with mean age of 63 years.

METHODS:

Shockwave therapy was applied to the treatment group while routine physical treatment was conducted to the control group. Simple McGill pain questionnaire(MPQ) was used to evaluate the general reactions of patients to pain and assess the shoulder joint territory and clinical effects.therapeutic effects.

RESULTS:

There was significant difference on sensory, affective and pain score, visual analogous scale(VAS) and pain presentation inventory(PPI) before and after treatment in the treatment group( t =5.69, 5.67, 7.06, 8.37,6. 21, P ＜ 0.01 ). When compared with control group, there was significant difference on sensory, pain score, VAS between the treatment group and control group(t =4. 66, P ＜ 0.01; t =2.52,3.40, P ＜0.05).

CONCLUSION:

Extracorporeal high-energy shockwave has reliable effects on treating chronic pain caused by bone joint myofascitis, which is characterized by its effective, quick and safe features.
