Impairment-based assessments for patients with lateral ankle sprain: A systematic review of measurement properties

STUDY DESIGN

Systematic review.

BACKGROUND AND OBJECTIVE

The International Ankle Consortium developed a core outcome set for the assessment of impairments in patients with lateral ankle sprain (LAS) without consideration of measurement properties (MP). Therefore, the aim of this study is to investigate MPs of assessments for the evaluation of individuals with a history of LAS.

METHODS

This systematic review of measurement properties follows PRISMA and COSMIN guidelines. Databases Pubmed, CINAHL, Embase, Web of Science, Cochrane Library and SPORTDiscus were searched for eligible studies (last search: July 2022). Studies on MP of specific tests and patient-reported outcome measurements (PROMs) in patients with acute and history of LAS (>4 weeks post injury) were deemed eligible.

RESULTS

Ten studies of acute LAS and 39 studies of history of LAS patients with a total of 3313 participants met the inclusion criteria. Anterior Drawer Test (ADT) in supine position five days post injury and Reverse Anterolateral Drawer Test are recommended in acute settings in single studies. In the history of LAS patients, Cumberland Ankle Instability Tool (CAIT) (4 studies) as a PROM, Multiple Hop (3 studies) and Star Excursion Balance Tests (SEBT) (3 studies) for dynamic postural balance testing showed good MPs. No studies investigated pain, physical activity level and gait. Only single studies reported on swelling, range of motion, strength, arthrokinematics, and static postural balance. Limited data existed on responsiveness of the tests in both subgroups.

CONCLUSION

There was good evidence to support the use of CAIT as PROM, Multiple Hop, and SEBT for dynamic postural balance testing. Insufficient evidence exists in relation to test responsiveness, especially in the acute situation. Future research should assess MPs of assessments of other impairments associated with LAS.

Functional Knee Extension Test (FKET): Inter-rater palpatory agreement and visual analysis during a non-weight bearing functional assessment of the knee

OBJECTIVE

The purpose of this study was to evaluate the inter-rater reliability of the Functional Knee Extension Test (FKET), a non-weight bearing functional assessment of the knee that is utilized within clinical practice.

METHODS

The design was a single-session, test-retest reliability study. Active knee extension was assessed and documented by each examiner for each of the visual, palpatory and vastus medialis obliqus (VMO) components of the FKET on fifty-seven healthcare professionals.

RESULTS

The Kappa (κ) statistic for the inter-rater reliability for the visual, palpatory and VMO variables of the FKET were slight-to-fair (0.13-0.26), fair-to-moderate (0.39-0.50), and moderate-to-almost perfect (0.57-0.93) reliability, respectively. The p-values for all variables, besides 'Visual RIGHT: TibTubExt' and 'Visual LEFT: TibTubExt' indicated statistically significant evidence of agreement above random guessing. Estimates for κ on the 'VMO Quantity: No contact' and 'VMO Timing: Start then stop' variables could not be calculated as ratings only existed across one row of the crosstabulation.

CONCLUSION

This study demonstrated that the palpatory and VMO components of the FKET have sufficient reliability to justify utilization within clinical practice. Future research is needed to determine whether the implementation of a functional knee assessment protocol, including the FKET could enhance levels of reliability in clinical decision-making of knee function.

Inter-rater reliability for measurement of passive physiological movements in lower extremity joints is generally low: a systematic review

QUESTION

What is the inter-rater reliability for measurements of passive physiological or accessory movements in lower extremity joints?

DESIGN

Systematic review of studies of inter-rater reliability.

PARTICIPANTS

Individuals with and without lower extremity disorders.

OUTCOME MEASURES

Range of motion and end-feel using methods feasible in daily practice.

RESULTS

17 studies were included of which 5 demonstrated acceptable inter-rater reliability. Reliability of measurements of physiological range of motion ranged from Kappa -0.02 for measuring knee extension using a goniometer to ICC 0.97 for measuring knee flexion using vision. Measuring range of knee flexion consistently yielded acceptable reliability using either vision or instruments. Measurements of end-feel were unreliable for all hip and knee movements. Two studies satisfied all criteria for internal validity while reporting acceptable reliability for measuring physiological range of knee flexion and extension. Overall,however, methodological quality of included studies was poor.

CONCLUSION

Inter-rater reliability of measurement of passive movements in lower extremity joints is generally low. We provide specific recommendations for the conduct and reporting of future research. Awaiting new evidence, clinicians should be cautious when relying on results from measurements of passive movements in joints for making decisions about patients with lower extremity disorders.
