Purpose: A major amputation affects the patients' independence, well-being and HRQoL. However, prosthesis use and the impact on the patient's HRQoL are scarcely described. The aim was to compare HRQoL between walker and non-walker amputees. Secondary aim was to evaluate prosthesis use and habits.

Method: Ninety-eight patients with a major amputation due to peripheral arterial disease were included during 2014-2018. They were interviewed using EQ-5D-3L (HRQoL), Stanmore Harold Wood mobility grade (prosthesis use) and Houghton scale (prosthesis habits).

Results: Seventy-three patients completed the one-year follow-up, out of them 56 got a prosthesis. Twenty-three used it to walk both inside and outside. EQ-5D-3L at follow-up was increased in all patients in comparison to baseline (0.16 versus 0.59,p< 0.001). Patients walking with prosthesis had the largest improvement (0.12 versus 0.78,p< 0.001). A sub-analysis aiming to study the importance of independent movement showed an improved HRQoL at follow-up among those classified as prosthesis-user (p<0.001) and walker (p<0.001), but not among non-prosthesis users (p= 0.245).

Conclusion: Learning how to use, not exclusively to walk with, a prosthesis after an amputation is important for the patients' HRQoL. At follow-up, patients using their prosthesis to walk or to move to a wheelchair, showed an improved HRQoL compared to baseline.
