My right scalenectomy (2002)is still doing good. Left scalenectomy (feb 2010) I had scar tissue issues 10 months post surgery.
The exercises at Ando and Aston are prescribed after an eval so you have to see them for an eval since they are specific to your condition. You do need some props for them.
Once you visit them they give you a video exercise program online that you can sign into with the password given by them.
You can try calling them and have a phone consultation, I think their first consultation is free. Since I was able to travel to them, Dr. Ando told me he needed to see me for couple weeks, twice a week for him to be able to assess me and help me. There phone number is(714) 974 0330. Their website is www.andoaston.com and you can email Dr. Ando at arta@andoaston.com.
Hope that helps.
