I would ask a physical therapist. But let me say this...I'm 71 yrs old and just had surgery on L-2 thru S-1. 5 weeks ago and now can use a walker but not for long. I'm so weak. If anyone has has this surgery, please contact me. Maybe I'm trying to rush it, but this is one surgery you don't want to have. I was in a lot of pain before, but sure didn't expect this.😫😫
