Plain English Summary
Background and study aims
An ankle sprain is an injury to the tough bands of tissue (ligaments) that surround and connect the bones of the leg to the foot. During physical activity, the ankle may twist inward as a result of sudden or unexpected movement. Fatigue and joint position sense are two elements that affect ankle sprain. Joint position sense measures the individual’s ability to perceive the position of a joint. Fatigue impairs joint position sense, which makes the incidence of ankle sprain high. Ankle tape is widely used to prevent ankle sprain, but is still not approved if ankle tape improve joint position sense after fatigue. The aim of this study is to examine if ankle tape can affect the joint position of the ankle after muscle fatigue.
Who can participate?
Healthy adults aged 16 to 40 years old.
What does the study involve?
Participants are randomly allocated to one of two groups. Those in the first group do not receive any ankle tape. Those in the second group receive ankle tape. Participants are measured before and after muscle fatigue to assess the impact of the ankle tape.
What are the possible benefits and risks of participating?
There are no direct benefits or risks associated with participating.
Where is the study run from?
University Hospital Marburg (Germany)

Participants are randomly distributed into control (without ankle tape) and intervention (with ankle tape) groups In both groups, joint position sense was measured before and after local muscle fatigue. For participants in intervention group tape is applied just before the first test and it was removed after second test. Preventive taping for injuries to the lateral aspect of the ankle joint is used and applied according to Macdonald’s method. Fatigue protocol was applied by Biodex System Isokinetic Dynamometer 3. The local load applied to the ankle joint consisted of 30 consecutive maximal concentric/concentric contractions of the ankle evertors and invertors in the range of motion ROM (30° of eversion and 30° of inversion) at an angular velocity of 120°/s. Immediately after the fatigue protocol, joint position sense testing is initiated using the same methods as in the testing before fatigue, to minimize the effects related to recovery from fatigue.
Primary outcome measure
1. Active joint position sense (Joint position sense in Absolute Error (AE) and variable Error (VE)) is measured using the Biodex 3 at baseline
2. Passive joint position sense is measured using the Biodex 3 at baseline
3. Active joint position sense is measured using Biodex 3 after fatigue
4. Passive joint position sense is measured using Biodex 3 after fatigue
Secondary outcome measures
1. Fatigue Index (Fatigue Index = (initial peak torque - final peak torque) / initial peak torque * 100) is measured using Biodex 3 after first test
2. Work is measured using Biodex 3 after first test
3. Work at first third measured using Biodex 3 after first test
4. Work at last third measured using Biodex 3 after first test
