Therefore, by choosing this topic, a deeper understanding of evidence-based pain assessment and management was pursued. During pain assessment in clinical training, the physical therapist generally evaluated and documented the critical components of the pain assessment process by determining the location of pain, aggravating and mitigating factors of pain, and duration of pain for each patient complaining of pain ( Powell et al., 2010, p.67). These baseline subjective assessments depend on the use of pain measurement tools that assess pain intensity in order to quantify the severity and duration of the subjective experience of pain in a valid and reliable manner (Powell et al., 2010, p.67). Therefore, a pain measurement tool played a vital role in the pain assessment process. This should be selected appropriately regarding the practicality, applicability and acceptability of pain assessment tools for the individual patient's condition and used in conjunction with other pain assessments (Powell et al., 2010, p. 71). In other words, a pain assessment tool should be systematically selected to evaluate pain parameters, which include location and radiation, intensity, quality and pattern.,
