Purpose:Passive pain provocation tests (PPPT) are commonly used to diagnose FAIS but do not reflect functional restrictions. The deep squat test (DST) is a functional, weight-bearing test, but the clinical utility of the DST is unclear. Objective:To examine the validity and reliability of the DST in patients with confirmed FAISMethod:A Systematic Review registered with PROSPERO (CRD42020199249). Seven databases; CINAHL, Cochrane, Embase, Medline, PubMed, SportDiscus and Web of Science, were searched up until December 2021. Data was extracted independently, and the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) tool was used to evaluate the risk of bias. Result:1137 abstracts were found; 1119 were excluded after screening and 18 underwent full test review, excluding a further 17, with one meeting the search criteria. No studies reported the reliability of the DST. One study (n=78 hips) investigated criterion-based validity: pain on DST indicated a positive test and was compared with MRI and MRA measures of FAIS. QUADAS score demonstrated low risk of bias. They concluded the DST had a modest potential to identify those with FAIS, but low specificity suggested the test may yield a high number of false positives. Conclusion: Physiotherapists should use the DST with caution. Single study evidence supports its use, but despite its common use, limited information is available about the DST and further investigation is required.Impact:Further studies are needed to examine validity and reliability, including evaluating the DST with higher alpha angles to determine whether diagnostic utility is improved. |
