Injuries, Ankle Clinical Trial
Official title:
Multisegmented Foot Motion in Patients With Lateral Ankle Sprains and Chronic Ankle Instability
Lateral ankle sprains (LAS) and chronic ankle instability (CAI) are common musculoskeletal injuries that are a result of inversion injury during sport. The midfoot is frequently involved during inversion injury, is often overlooked during clinical examination, and maybe contributory to the development of CAI. The purpose of this study is to investigate multisegmented foot motion using a motion capture system, clinical joint physiological and accessory motion, and morphologic foot measurements in recreationally active men and women with and without a history of lateral ankle sprains and chronic ankle instability. Additionally, the effects of a joint mobilization intervention in patients with diminished multisegmented foot motion and intrinsic foot strengthening in healthy individuals will be investigated.
Arm 1:The purpose of this arm of the study is to determine if foot muscle exercises change
the function of the foot. Up to 25 people will be enrolled in this arm of the study at the
University of Virginia.
Arm 2: The purpose of this arm of the study is to determine if joint mobilization applied to
the middle part of the foot will effect function in people who are healthy, have a history
of lateral ankle sprains (LAS), or have chronic ankle instability (CAI) and have joint
stiffness. Up to 125 people will be enrolled in this arm of the study at the University of
Virginia. CAI is a condition where symptoms from an ankle sprain last longer than one year.
These symptoms include a feeling of looseness, feelings that the participant may roll the
ankle, or repeated ankle sprains. This study may help clinicians prescribe simple exercises
at home to help treat CAI. The participants are being asked to be in this study, because
they are physically active (participate in some form of physical activity for at least 20
minutes per day, three days per week) and are not currently seeking medical
treatment/therapy for LAS/CAI. Joint mobilization is a commonly used clinical intervention
used to decrease pain and increase joint range of motion. The home exercises employed for
this study are commonly used clinically in the treatment of foot and ankle problems and
include a foot and calf stretch and standing on one foot for 60 seconds. The participant
will be asked to perform these exercises three times daily throughout the course of the day.
The investigators hypothesize that joint mobilization will improve patient oriented outcomes
and measures of joint mobility and excursion in individuals with impaired foot mobility
immediately post intervention and at 1-week follow-up, but not at 4 weeks; and intrinsic
foot strengthening will result in differences in morphologic measures and intrinsic muscle
cross-section in healthy individuals following a 4 week home exercise program.
