(Concern) Post-treatment care for frozen shoulder

I barely treated frozen shoulder over a period of six months.

However, my right shoulder is not perfect.

In the past, both sides could hold the handle behind their back, but now one side cannot.

The stage of treatment has been surpassed, but it's not perfect.

What should I do to improve the condition a little more?

I loosen it with a foam roller or SNPE wooden roller.

But there isn't much traffic.
