A comparison between vibration and ultrasound waves accompanied with stretching exercises on improving function in athletes with posterior neck muscles' myofascial trigger points
This study aimed to compare the effect of vibration and ultrasound therapy accompanied with stretching exercises on myofascial trigger point of posterior neck muscles in athletes. Thirty patients with posterior neck muscles' myofascial trigger points were recruited through simple non probability sampling and they were randomly assigned to either a vibration (n=15) or an ultrasound therapy accompanied with stretching exercises group (n=15), in 2008-2009. A 10-session program which lasted 4 weeks, 3 sessions per week, and 30 minutes per session was performed for both groups. Before and after the intervention, neck disability (ordinal) was assessed with Neck Disability Index (NDI), neck pain with visual analog scale (ordinal) and Northwick Park Neck Pain Questionnaire (NPNPQ), and shoulder pain and disability with Shoulder Pain and Disability Index (SPADI).
