Clinical decision making for using electro-physical agents by physiotherapists, an Israeli survey

Background: Electro-physical agents (EPAs) are fundamental components in the management arsenal of physiotherapy. The objective of this study was to provide a comprehensive understanding of the factors affecting the decisions made by Physiotherapists (PTs) when choosing to apply EPAs as a treatment modality. Methods: A purpose-designed questionnaire was developed to investigate the contribution of 13 factors on the decision to use EPAs. Two hundred questionnaires were randomly distributed to PTs attending the annual conference of the Israeli Physiotherapy Society, 2014. The factors were grouped into six categories and Wilcoxon Sign Rank tests were applied to compare their impact on decision making. Results: In total, 144 (72%) questionnaires were completed. Good internal consistency was found for the 13 component of the decisions factors (Cronbach's coefficient alpha = 0.77) with unequal distribution of answers in each question (p < 0.01). Conclusion: The participating PTs were likely to make decisions which were strongly impacted by availability of equipment and operational factors. This research can be used to provide practicing PTs with a basis for a critical appraisal of their decision making regarding the application of EAPs. In addition, due to the strong impact of availability of equipment, health policy makers should verify that the available equipment is up to date with the best research evidence.
