Abstract

Study Design: Cross-sectional.

Introduction: Southampton Hand Assessment Procedure (SHAP) provides function scores for hand grips (prehensile patterns) and an overall score, the index of function (IOF). The underlying equations of SHAP are not publicly available, which induces opacity. Furthermore, SHAP has been scarcely tested in prosthetic users.

Methods: Issues with SHAP-IOF are discussed: an alternative scoring system, that is, linear index of function (LW) and a weighted version (W-LIF) are presented. In LIF, task times are transformed linearly, relative to SHAP norms, and are computed into LIF-prehensile patterns (LIFpp). LIF and IOF were compared using data of 27 experienced prosthetic users.

Results: High correlation and agreement between LIF and IOF was found: LIFpp vs IOFpp ranged from r = 0.880 to r = 0.988, and W-LIF vs 10F had a correlation coefficient of r = 0.984.

Discussion: SHAP data of prosthetic users are valuable benchmarks for health care professionals. LIF calculations are a good and cost free alternative for 10F scores.

Conclusion(s): Measurements with LIF and 10F may be considered similar, but LIF is transparent and easier to use than 10F. Level of Evidence: Clinical measurement and cross-sectional. (C) 2016 Hanley & Belfus, an imprint of Elsevier Inc. All rights reserved.
