hi,
as already stated by our friends,it is importatnt to throughly asess the subject by exposing the shoulder and the scapular region as well,as most of the cases of Wikipedia reference-linkfrozen shoulder go misdiagnosed.pain relief will occur as soon as the GH capsule is stretched ,so cryotherapy will cover the pain prior to stretching.Start gradual strethcing of the capsule in flexion,abbduction and in lateral rotation(90-90 stretches),start strengthening the deltoids,ssp,isp in the available ranges.(therabands preferred to free weights) and examine for scapular stabilisation,strengthen muscles around scapula as the entire GH rhytm is altered following GH range restrictions.Pain relieving modalities better if used SOS.
