Purpose:

To determine the optimal timing (post-amputation) for conducting the AMP, which predicts walking ability with a prosthesis in amputees

Methods:

A cross-sectional study was conducted with 45 participants from the orthopedic rehabilitation department at Loewenstein Rehabilitation Medical Center. The inclusion criteria were: (1) Patients who underwent lower limb amputation (due to trauma or vascular causes) at the hip, knee, shin, or partial foot level, (2) Patients with bilateral amputation due to trauma, (3) Age over 18, (4) Hospitalized patients undergoing prosthetic walking rehabilitation, (5) Patients who consented to participate, and (6) Patients able to understand the instructions. Exclusion criteria included any medical condition causing temporary physical limitations. The participants were evaluated using the AMP without prosthesis (AMPnoPRO) and MFCL - K Level tests administered by a physiotherapist upon admission and at two-week intervals during their hospitalization, with assessments conducted over four time points. AMP and MFCL - K Level tests were also performed with the prosthesis (AMPPRO).



Results:

The AMPnoPRO and MFCL - K level scores differed significantly across time points. The AMPnoPRO score showed significant differences between admission and all subsequent time points but stabilized after two weeks post-admission (p0.001 for all comparisons). MFCL - K level scores also differed significantly from admission and from two weeks post-admission and all other time points (p0.011 for all), stabilizing after four weeks. The AMPPRO score at discharge was significantly correlated with AMPnoPRO scores at earlier time points (Pearson r > 0.7313, p 0.001), and the MFCL - K level score at discharge was significantly correlated with MFCL - K level scores at previous time points (Spearman's rho > 0.671, p 0.001

Conclusion(s):

The optimal timing for administering the AMP and MFCL - K level assessments appears to be at least two weeks and four weeks post-amputation, respectively.

Implications:

will help in making a decision at the best time to order a prosthesis, and the components of the prosthesis, which can help the amputee's function
