> From a total of 54 patients, 27 received a steroid injection into the shoulder joint, along with physiotherapy and the suprascapular nerve block at the 3-monthly intervals, while the other 27 patients received the steroid injection and physiotherapy with a placebo injection.

>“We found those who received the nerve block reduced the duration of their symptoms by an average of 6 months, while also reporting lower pain and disability scores and improved range of movement, compared to the placebo group,” says Professor Shanahan.

>“For patients in the placebo group, the average time for their symptoms to resolve was over 11 months, while for those who received the nerve block this was practically halved, down to around 5 and half months.”
