Do Patients Unconsciously Associate Suggestions for More-invasive Treatment with Better Care?

Clin Orthop Relat Res 2019 Mar;477(3):514-522

J. T. P. Kortlever, J. S. E. Ottenhoff, T. T. H. Tran, D. Ring, G. A. Vagner, M. D. Driscoll, Department of Surgery and Perioperative Care, Dell Medical School - The University of Texas at Austin, Austin, TX, USA.

Background: It seems common for patients to conceive of care in physical terms, such as medications, injections, and procedures rather than advice and support. Clinicians often encounter patients who seem to prefer more testing or invasive treatments than expertise supports. We wanted to determine whether patients unconsciously associate suggestions for invasive treatments with better care. Read More

Progression in Running Intensity or Running Volume and the Development of Specific Injuries in Recreational Runners: Run Clever, a Randomized Trial Using Competing Risks.

J Orthop Sports Phys Ther 2018 Oct 12;48(10):740-748. Epub 2018 Jun 12.

Background: It has been proposed that training intensity and training volume are associated with specific running-related injuries. If such an association exists, secondary preventive measures could be initiated by clinicians, based on symptoms of a specific injury diagnosis.

Objectives: To test the following hypotheses: (1) a running schedule focusing on running intensity (S-I) would increase the risk of sustaining Achilles tendinopathy, gastrocnemius injuries, and plantar fasciitis compared with hypothesized volume-related injuries; and (2) a running schedule focusing on running volume (S-V) would increase the risk of sustaining patellofemoral pain syndrome, iliotibial band syndrome, and patellar tendinopathy compared with hypothesized intensity-related injuries.
