A STUDY ON VALIDITY AND RELIABILITY OF SPEED AND YERGASON TEST AMONG PATIENTS WITH CHRONIC PAINFUL RESTRICTED SHOULDER IN NORTHERN DISTRICTS OF WEST BENGAL

Abstract

Introduction: High resolution Ultrasonography (HRUSG) is increasingly useful for the assessment of shoulder pain clinically diagnosed to be
bicipital tendinitis because of the fact that various clinical tests often do not offer an exact diagnosis on type of structural damage. Only to validate
the exact type and severity of damage to peri-articular and intra-articular soft tissue pathology along with the clinical findings HRUSG is a low cost,
safe and easily accessible tool available to physiatrists in clinical practice.
Objective: The aim of this study was to identify, compare and validate the findings of clinical examination with high resolution Ultrasonography
(HRUSG) in the selected patients presenting with chronic painful shoulder disorders of various duration and severity in the Out Patient Department
(OPD) based clinical Practice.
Methods: Non-interventional observational study of adult patients suffering from unilateral shoulder pain clinically diagnosed as bicipital
tendinitis at OPD. The clinicians at PMR OPD performs the clinical shoulder examinations after recruitments of the patients from various clinics
including orthopedics, General Clinic as well as PMR OPD and after that sono imaging were done to them by senior sonologist specially
experienced in musculoskeletal and soft tissue sonography with the support from radiology department. Later on results as available from clinical
and sonographic examination were blinded to each other being provided to another investigator for analysis and corroboration.
Results: Total 99 patients has been selected out of them 57 were males and 42 females, of whom the mean age was 42.7 ± 09.51 years (range 23-57
years). In clinical examination it was revealed that the Speed and Yergason test showing respectively sensitivity of 71.3% & 57.7%, specificity of
75.9% & 95.2%, positive predictive values of 67.5% & 85.3% and that of Negative predictive value 77.5% & 71.9%, positive likelihood ratio 3.93
& 7.13, negative likelihood ratio 0.41 & 0.55, Cohen's κ coefficient 0.521 & 0.439.
Conclusion: Clinical tests are of not conclusive in detecting bicipital tendinitis.
