neurological impairments
The present study is to our knowledge the first RCT study also reporting evaluation of neurological outcomes based on a clinical examination with a two-year follow-up after surgery and postoperative rehabilitation in patients with CR. The results showed no between- group differences, that persistent neurological impairments were common at follow-up, and the outcomes are less positive than previous results from RCTs after surgery reporting above 80% improvements in neurological function
