N=30,
During my PM&R residency in INDIA, currently a neurorehab fellow and will be starting PM&R pgy-1 july 2008. I presented a poster on this topic at AAPMR 2007, Boston, abstract was published in subsequent online archives of PM&R.
Breifly, I did a study to compare efficacy of hyalgan in adhesive capsulitis with conservative management, what I did, was I gave 5 injections a week apart and then follow up all the patients over 3 and 6 months, P<0.05 for pain, and has a carryover effect, did not acheive statistical significance in terms of ROM and Overall functional status. I also used it for resistant cases, those who failed 6-8wks of conservative treatment -- definitely good results but no data or statistics to support this.
I didn't used any radiological evidence to support, I got support for these costly injections as most of my patients are hospital employees and covered under Employee State Insurance. I want to conduct this study furthur in US at montefiore where I will be doing my residency.
I attended annual Canadian PM&R annual meeting and some rheumatologist was presenting on using hyalgan for multiple musculoskeletal conditions not sure about shoulder.
I hope this helps
