VALDCAST

In this episode of VALDCAST, Roula Kotsifaki shares insights from her extensive work in sports medicine, rehabilitation and force plate research, exploring how clinicians can use jump testing to make better decisions throughout the rehabilitation process. Drawing on years of experience working with ACL populations, Roula explains why getting the fundamentals right, including test execution, cueing and standardisation, is critical before any meaningful interpretation of data can take place. 

Roula discusses how practitioner cueing can influence jump performance, why consistent testing protocols matter and the importance of balancing athlete intent with reliable data collection. She also breaks down the evolution of drop jump testing over the past decade and why improved understanding of test execution has changed how practitioners interpret metrics like contact time and reactive performance.  

The conversation also unpacks:

• Why standardised testing and athlete cueing are essential for meaningful data interpretation
•  How practitioners can reduce metric overload and focus on the information that actually guides rehabilitation
•  Why reliability, responsiveness and clinical relevance should drive metric selection
•  The growing role of drop jumps and single-leg drop jumps in ACL rehabilitation and return-to-sport testing
•  How force plate data can be used to identify deficits across eccentric, concentric and landing phases of movement
•  Why education, consistency and practitioner confidence are crucial for the future of rehabilitation testing

Roula also reflects on the importance of clinical reasoning, the challenge of translating research into practice and where she sees the future of jump testing and rehabilitation assessment heading as the industry continues to evolve.
