Chris and Sam sat down with Karin Silbernagel to discuss achilles tendinopathy and achilles tendon ruptures. In the first half of our conversation with Karin, we discuss tendinopathy versus tendinitis and tendinosis, diagnostic criteria, biggest findings over the past 1-2 decades regarding tendon related research, insertional versus mid portion achilles tendon pain, average recovery timelines, pain during rehab and training, and much more. In the latter half of our conversation, we chat about achilles tendon ruptures including risk factors, surgical versus non-surgical considerations and recommendations, and objective testing. Karin is a researcher, professor, clinician, and the Associate Chair of the Physical Therapy Department at the University of Delaware.
