Ultrasound Therapy.

Uses very high frequency sound  that can help deep muscle release.  This therapy can also help non-acute tendonitis and scar tissue.  

I found this therapy very useful in relaxing difficult -to-release neck, shoulder and hip muscles. 

 

Combination of ultrasound therapy with other approaches can achieve faster results than just being limited to one modality.
