Development and psychometric properties of the Basic Amputee Mobility Score for use in patients with a major lower extremity amputation

摘要: Aim To develop and examine the psychometric properties, including responsiveness interrater reliability, of a new outcome measure for evaluation basic mobility activities after major lower extremity amputation – The Basic Amputee Mobility Score (BAMS). Methods The four following essential were chosen through consensus meetings with experienced amputee physiotherapists: (i) supine in bed to sitting on edge bed; (ii) wheelchair transfer; (iii) indoor mobility; (iv) get up from standing non-amputated leg. Each activity is scored 0 2 (0 = not able to; 1 assistance/guiding; independent), cumulated 1-day BAMS score 0–8. Validity established 106 consecutive in-hospital patients dysvascular amputation, while reliability agreement examined an additional sample 30 patients. Results The 30-day mortality risk was reduced by 88% (HR 0.12, 95% CI 0.02–0.68) those out (BAMS ≥2 points) at first physiotherapy assessment, scores improved between discharge standardized response mean 1.3. Reliability assessments resulted weighted Kappa value 0.98, standard error measurement 0.32 minimal detectable change 0.89 points. No systematic between-rater bias seen (P 0.3). Conclusions The feasible all patients, showed large responsiveness, excellent point indicating real performances. Geriatr Gerontol Int 2018; 18: 138–145.
