Whole Body Cryotherapy (WBC) has shown its effectiveness in reducing the inflammatory process by vasoconstriction at the muscular level caused by the decrease in activity of pro-inflammatory cytokines and increase in anti-inflammatory cytokines.
This may be a reason why WBC is showing very promising results in treating Frozen Shoulder (Adhesive Capsulitis).
According to Hyeong-Dong Kim (Korea University, Seoul) and colleagues:
30 patients participated in a 4 week study. The WBC group showed 20% of improvement compared to physical therapy and mobilization without WBC. At the completion the WBC group had a decrease in pain from 6 to 2.5 points on the VAS (visual analog scale), traditional therapy went from 6 to 3.7. WBC obtained 90% improvement in internal rotation compared to the traditional therapy alone.
