• Lead Sponsor: Pamukkale University

Brief Summary

30 patients with chronic cervical myofascial pain (4 males, 26 females) aged between 25 to 57 years (with average age 41,20±10,23 years) were included the study.

Participants were divided into two groups as intervention group (n=15) and control group (n=15). Patients in intervention group received radial shock-wave application one times a week for six weeks and home based stretching exercises. Patients in control group (CG) received home based stretching exercises. Rest and activity pain (Visual Analog Scale), pressure pain threshold (PPT), cervical range of motion (CROM) and disability (Neck Disability Index) were assessed at baseline and after the treatment.

Detailed Description

Thirty-four cervical MPS patients aged between 25-57 years (average age: 41,20±10,23 years) who diagnosed cervical MPS (myofascial pain syndrome), had cervical MPS for 6 months and who had at least one trigger point on their cervical, back and shoulder muscles were included to this study.

Thirty-four participant were included to the study. Taking into consideration including and excluding factors 34 participants divided into two groups: intervention shock-wave therapy group, control group. Because of several private reason (not attending treatment regularly and not participating in the final evaluations), 4 participant were excluded from study.

All assessments done by the same physiotherapist (FU) before the first session and one week after the last treatment session. Demographic data of participants recorded by using a form at the baseline of the study.

Patients in the intervention group (n=15) received 6 sessions radial shock wave treatment once a week during 6 weeks. During the treatment, the patients sat on chairs and supported their upper bodies with a pillow on the bed. Ultrasound gel was applied to the application area. Radial shock-wave therapy was applied to each trigger point in the preliminary evaluation. The muscles related trigger points were stretched position during the application. Radial shock-wave therapy was applied in 1.0-4.0 bar intensity, 10-15 hz frequency interval. 300-700 pulse for a trigger point, 1500-3000 pulse for a muscle. Intensity, frequency and pulse increased every session regularly beginning from minimal taking patients tolerance into consideration. Trigger points in the upper, middle and lower trapezius, supraspinatus, infraspinatus and levator scapulae muscles were treated.

Neck and upper back muscle static stretching exercises were teached to patients in the both groups as home exercise program. The patients were asked to do each stretching exercise given as a home-based program every day, 3 times a day and 3 repetitions. The exercise program consisted of static neck lateral flexors stretching, shoulder posterior capsule stretching and apley stretching exercises. Exercise booklets were prepared and given to the patients.

Arm && Interventions

Group	Intervention	Description
Radial shock-wave group	Radial Shock-Wave Therapy	Group I (15 subjects) received radial shock-wave application one times a week for six weeks and home based stretching exercises.
Control	Control	Group II (15 subjects) received home based stretching exercises for six weeks.

Primary Outcome Measures

Name	Time	Method
Pain Intensity	Baseline	Pain intensity was measured using a Visual Analogue Scale (VAS) measuring 10 cm (0: I have no pain, 10: I have an intolerable pain).
Disability	Baseline	Turkish version of Neck Disability Index (NDI) was used to assess the disability caused by neck pain.
Pressure pain threshold (PPT)	Baseline	Digital pressure algometer applied to patients active trigger points.
Cervical Range of Motion	Baseline	Cervical range of motion (CROM) tool was used to assess cervical range of motion. Measurements were repeated three times in flexion, extension, rotation and lateral flexion directions.

Secondary Outcome Measures

Name	Time	Method
Pain Intensity	6 weeks	Pain intensity was measured using a Visual Analogue Scale (VAS) measuring 10 cm (0: I have no pain, 10: I have an intolerable pain).
Disability	6 weeks	Turkish version of Neck Disability Index (NDI) was used to assess the disability caused by neck pain.
Cervical Range of Motion	6 weeks	Cervical range of motion (CROM) tool was used to assess cervical range of motion. Measurements were repeated three times in flexion, extension, rotation and lateral flexion directions.
Pressure pain threshold (PPT)	6 weeks	Digital pressure algometer applied to patients active trigger points.
