Abstract:
Background: Ankle sprain is common and can lead to chronic ankle instability (CAI), characterised by decreased functional performance. However, there is still a limitation regarding the optimal approach used to assess functional recovery. This thesis aimed to explore the functional performance of those subjects and to investigate their progress plus to identify recovery predicator. Methods: 60 subjects (Acute Sprain (AS)=20, CAI=20, Healthy=20) were recruited. Parameters investigated: decision-making (DMT) and task time (TT) under unanticipated and planned conditions, Time to Peak muscle activity (TTP), jump height, muscle strength, and dorsiflexion ROM. These were also used to investigate the progress of the AS=10 over a six-month period and to identify recovery predicator. Results: The healthy subjects demonstrated faster DMT only during unanticipated conditions comparing with AS (p=0.003) and CAI (p=0.001). DMT was also longer in CAI compared with AS by 51.8ms (p=0.03). A significant difference was found in jump height between injured and non-injured ankles for the AS and CAI subjects and better dfROM in the healthy subjects. Measuring TTP revealed that the TTP occurred in a different order in each group. In the longitudinal study the AS subjects performed better DMT by 74.2ms and jump higher by 1.68cm when compared with the 1st visit. Additionally, Jump height found predictor of functional outcome score at 1-month using FADI-ADL% and also muscle strength (Eversion Con-PT, Eversion Con-PT/BW and Eversion Ecc-PT/BW) can predict the functional outcome at 12-month using FADI-Sport %. Conclusion: This thesis suggest that using unanticipated conditions in functional tests could provide important performance outcomes such as DMT in assessing the ability to return to previous sporting activity. A combination between jump height and fast contact time is also useful. Overall the result provides a foundation for further investigations. Larger and more detailed studies are also needed to investigate muscle activity in response to an unanticipated condition.
