Hanger announces results of landmark study in lower limb amputees correlating higher mobility with higher patient satisfaction and quality of life

Published in Prosthetics & Orthotics International, Mobility Analysis of Amputees evaluates largest lower limb prosthetic data set to date

AUSTIN, Texas, Oct. 10, 2017 /PRNewswire/ -- Hanger, Inc. (OTC PINK: HNGR) today announced the first results of its landmark study in lower limb amputees known as the Mobility Analysis of Amputees (MAAT I). The largest of its kind to date, the study measured the correlation of mobility to quality of life and patient satisfaction for people living with lower limb loss, with findings demonstrating a significant direct correlation. The clinical research was peer reviewed and published in a Medline journal, the prestigious Prosthetics & Orthotics International.

The results of the MAAT I study demonstrated a statistically significant direct correlation of higher mobility with higher quality of life (p<0.001, r=0.511) and patient satisfaction (p<0.001, r=0.475) in a sample size of 509 patients living with lower limb loss. Specifically, mobility accounts for approximately one quarter of the variance associated with quality of life and general satisfaction (26.1% and 22.6%, respectively). As a modifiable factor with significant impact on both quality of life and satisfaction, prosthetic mobility represents a substantial factor that should be addressed by the rehabilitation team.

"Functional mobility is compromised in individuals dealing with lower limb loss, and this study provides strong evidence that maximizing mobility should be considered a primary goal in providing holistic patient care," stated James Campbell, PhD, CO, FAAOP, chief clinical officer, Hanger Clinic.

Colleagues in the clinical and scientific affairs department of Hanger Clinic, including James Campbell, PhD, CO, FAAOP, Shane R. Wurdeman, PhD, CP, FAAOP, and Phil M. Stevens, MEd, CPO, FAAOP, began the study by performing a retrospective review of outcomes data collected within multiple clinics. Included with the data obtained was the Prosthetic Limb Users Survey of Mobility and Prosthesis Evaluation Questionnaire. Analysis included 509 current prosthetic users, individuals age 18 or older, with varying amputation levels, including both unilateral and bilateral lower limb amputation.

"We are very proud of the publication of these important research findings, as this is another example of Hanger Clinic leading the orthotics and prosthetics profession in evidence-based outcomes," stated Hanger President & CEO Vinit Asar. "As the largest provider of prosthetic care in the nation, we are in a position to collect and publish previously unknown insights that can aid in the protection and improvement of patients' access to proper care."

The MAAT I study is the first in a series Hanger Clinic is undertaking in support of the development of evidence-based care for amputees. The outcomes from the MAAT I study are set to be published in an upcoming hardcopy print edition of Prosthetics & Orthotics International, and is available early release online here:
