Biomechanical differences in jump landings

"Biomechanics of Change of Direction Tasks Following Landings in People with Chronic Ankle Instability"


The purpose of this research study is to determine if biomechanical differences exist in jump landings with change of direction between uninjured people and those with chronic ankle instability.

Research involves

  • A time commitment of roughly 1 hour and 30 minutes during one testing session

  • Coming into the Neuromechanics Lab for testing (located in the Women’s Building basement at OSU)
  • Completing a series of jump landing into change of direction tasks as well as a series of single leg balance trials

To qualify

In order to qualify for this study participants must:

  • Be 18-35 years of age
  • Not be pregnant
  • Have participated in at least 2 seasons of competitive sport involving jump landings within the past 10 years, such as basketball, volleyball, soccer, tennis, etc.
  • Currently be performing at least 90 minutes of cardiovascular, strength, or sport-related physical activity per week
  • Be free of current swelling and bruising of the ankle joint
  • Have no history of surgery to either lower extremity
  • Have no history of fracture in either lower extremity
  • Have no injury to the lower extremity in the previous 3 months that caused 1 or more days of restricted physical activity
  • Have no history of a diagnosed vestibular disorder, Ehlers-Danlos syndrome, or photosensitive epilepsy

Participants who meet these initial criteria will additionally be screened for presence of chronic ankle instability and ankle joint laxity or looseness through self-reported questionnaires and a manual ligament laxity test.
