Mobility Analysis of AmpuTees (MAAT 7): Normative Mobility Values for Lower Limb Prosthesis Users of Varying Age, Etiology, and Amputation Level.

This was a retrospective cross-sectional database review, so it can show recorded differences but cannot show that age or cause of amputation caused those differences. The analysis used each patient's highest PLUS-M score instead of the latest score, so the values represent best reported mobility and may overstate current function. Mobility was patient-reported, which can be influenced by recall or imprecision. The study included only unilateral amputation, so the values do not apply to bilateral amputation. Some age and cause groups, especially congenital groups, had fewer than 15 people and were omitted from statistical models, reducing certainty for those subgroups. The study did not account for how long a person had used a prosthesis or for access to advanced prosthetic components, which may affect mobility.

The paper reports that financial disclosure statements were obtained and no conflicts of interest were reported by the authors or by anyone in control of the content.

Do not read these values as proof that a treatment works or that diabetes or dysvascular disease causes low mobility. The study is descriptive and used the best reported score, so it shows what mobility levels were recorded, not what caused them or what intervention would improve them.
