For the correct height and best way to use the cane see a physical therapists who is familiar with canes. The therapist will be your greatest resource in learning which cane would be best for you, a quad or single leg cane. I had gone to physical therapy outpatient services once a week just to learn exercises to do at home. It was there I first learned about quad canes. The therapist had brought it to my attention. Without the therapist I would have never thought to benefit from a cane. I think it would be a good investment for at least one visit to determine which cane would be appropriate and to use correctly. My insurance did pay for my visits after I met the copay. Check with your medical insurance. Wish you well. Toni
