Went to a physio this week about a recurring knee issue and she used a series of muscle activation techniques pioneered by Douglas Heel. This was all new to me. First worked on my diaphragm, then psoas, then my jaw and back of neck to activate my glutes?! All in relation to my knees. It was incredible. Knees not recovered yet but I did feel immediately some sense of pain relief. Anyone else have experience of this technique and how did you find it helped you recover?
