Not yet recruiting

• Conditions: Developing a Consensus Framework to Standardize Isokinetic Testing Data Reporting

• Registration Number: NCT06733116
• Lead Sponsor: University Hospital, Caen

Brief Summary

Isokinetic testing plays a crucial role in research and clinical practice, particularly for evaluating muscle strength, functional performance, and imbalances between muscle groups in fields such as rehabilitation, sports medicine, and orthopedics. Despite its widespread use, there is no international consensus on how to standardize protocols or report results, leading to significant variability in methodologies, measurement parameters, and data presentation.

This Delphi method study aims to develop a consensus framework for standardizing the reporting of isokinetic testing data, ensuring consistency and comparability in research and clinical practices.

Detailed Description

Isokinetic tests are widely used in research and clinical practice to evaluate muscle strength, imbalances between muscle groups, and functional performance. These assessments are particularly important in rehabilitation, sports medicine, and orthopedics. However, the diversity in testing protocols, measured parameters, and reporting methods creates significant challenges for the comparability and interpretation of results.

Currently, there is no international consensus on how to report isokinetic test results. Scientific publications and clinical reports vary greatly in methodologies, units of measurement, and presentation of findings. Additionally, there is considerable heterogeneity in how results are presented, particularly regarding essential elements that ensure methodological reproducibility. This variability complicates the synthesis of data across studies and limits their practical application. As a result, healthcare professionals and researchers struggle to compare results, replicate studies, or effectively use the data in clinical decision-making.

The need to standardize reporting practices for isokinetic tests is therefore clear. A standardized framework would harmonize reporting, facilitate comparisons between studies, support the evaluation of therapeutic interventions, and improve the monitoring of patients or athletes over time. It would also enhance transparency and scientific rigor, which are critical for advancing knowledge and improving care.

The Delphi method, used in this study, is particularly suited to addressing this issue. It relies on an iterative process to gather the opinions of a panel of experts and establish a consensus on specific recommendations. By involving experts from various fields (physicians, physiotherapists, kinesiologists, and sport physiologists), this method ensures that the recommendations reflect a broad and balanced perspective. It also helps structure and prioritize key points, identifying essential elements for a standardized report.

The results of this study are expected to have several significant outcomes. First, they will provide a clear framework for standardizing the reporting of isokinetic tests, improving the quality and utility of the data reported. Second, this framework could be adopted internationally, fostering better collaboration between researchers and clinicians. Finally, it could serve as a foundation for developing official guidelines or recommendations, enhancing the validity and impact of isokinetic testing in clinical and scientific practices.

Primary Outcome Measures

Name	Time	Method
Consensus on Key Elements for Standardized Reporting of Isokinetic Testing	At the completion of the final Delphi round (approximately 6 months).	The proportion of agreement among experts on the key elements to include in a standardized framework for reporting isokinetic testing data, as determined by the final round of the Delphi process. Agreement will be defined as at least 80% agreement (4 or 5 on a 5 -level Likert scale, minimum=1 maximum=5, 5 corresponding to 'strongly agree')

Secondary Outcome Measures

Name	Time	Method
Open Survey to Inform Delphi Rounds	At the end of the first Delphi round (approximately 2 month)	The identification and categorization of items related to isokinetic testing, informed by an initial literature review and expert input during Round 1 of the Delphi process.
Prioritization of Reporting Items	During intermediate Delphi rounds (approximately 3-4 months).	Ranking of reporting items by importance ("1 = optional", "2 = recommended", "3 = essential"), with 'essential' indicating that the item is mandatory, based on iterative feedback from Delphi panelists.
Years of Professional Practice	At the beginning of the Delphi process (baseline).	Average and range of years of professional experience in fields related to isokinetic testing (e.g., sports medicine, rehabilitation, research).
Academic Contributions	At the beginning of the Delphi process (baseline).	Number of peer-reviewed publications or other academic contributions related to isokinetic testing or related fields, self-reported by the participants.
Geographic Distribution of Expert Panel Participants	At the beginning of the Delphi process (baseline).	Distribution of experts by geographic region (e.g., continents, countries) to evaluate the representativeness of the panel.
Expert Panel Composition - gender	At the beginning of the Delphi process (baseline).	Analysis of gender distribution within the expert panel
Expert Panel Composition - country	At the beginning of the Delphi process (baseline).	Analysis of the country of residence distribution within the expert panel
Expert Panel Composition - job	At the beginning of the Delphi process (baseline).	Analysis of the type of job distribution within the expert panel
