“…This is in line with a previous case study describing kinematics of an ankle sprain that reported markedly lower plantar flexion in the injury trial compared with the normal trials for the first 200 ms of the stance (Fong et al, 2009). A low plantar flexion was also seen in a recent study investigating ankle sprain biomechanics for two cases using a model-based motion analysis technique (Mok et al, 2011). This implies that plantar flexion is not required for injury to occur.…”

“…Two previous reports describe the kinematics of accidental ankle sprains using video analysis, but kinetic descriptions are lacking (Fong et al, 2009;Mok et al, 2011). A more precise description of moments acting on the ankle at the time of injury would improve understanding of the injury mechanisms.…”

“…If there is a decline in peroneus muscle activity, resulting in an inverted ankle position at landing, the incidence of a recurrent ankle sprain and a feeling of "giving way" may be increased, even if the peroneus muscle reacts normally. Previous studies have demonstrated that the time-to-peak inversion angle of the ankle sprain was approximately 80 ms to 200 ms post-IC [38][39][40][41] . Konradsen et al 15) suggested that protecting the ankle against sudden inversion was difficult after the foot is in contact with the ground, due to the ankle eversion against a sudden inversion stimulus occurring later than 176 ms.…”

The purpose of this study was to investigate postural stability and lower leg muscular activity in male collegiate soccer players with functional ankle instability (FAI), during a diagonal landing. Twenty-two male collegiate soccer players were divided into an FAI group (n = 11) and healthy control group (n = 11). Muscle reaction times for sudden ankle inversion were measured to evaluate neuromuscular control in the peroneus longus (PL), peroneus brevis (PB), tibialis anterior (TA), gastrocnemius lateral head (GL), and gastrocnemius medial head (GM). Time to anteroposterior stabilization (TTSAP), time to mediolateral stabilization (TTSML), and activity of these muscles during a diagonal single-leg landing was measured. Reaction times in the peroneus muscles were delayed in the FAI group, compared to the control group (PL: P < 0.01, PB: P = 0.02). TTSML was increased in the FAI group, compared to the control group (P = 0.02). Muscular activity of PL, PB, and TA were reduced in the FAI group, compared to controls, during a diagonal single-leg landing (PL: P < 0.05, from 87 ms pre-initial contact [pre-IC] to 108 ms post-initial contact [post-IC], PB: P < 0.05, from 180 ms pre-IC to 123 ms post-IC, TA: P < 0.05, from 65 ms to 203 ms post-IC). Male collegiate soccer players with FAI had increased TTSML and reduced muscle activity in PL, PB, and TA during diagonal single-leg landing. It is important for clinicians to assess the postural stability and function of the lower leg muscle activity, during rehabilitation after ankle sprains.

“…Current analysis techniques, including those of real time injury mechanisms, and findings in laboratory studies, have shown the mechanism to be inversion and internal rotation of the foot [18,19]. These findings indicate inversion velocities of up to 1,752 degrees/second and maximum inversion angles of up to 142° [20]. The injury is defined by damage to the lateral ankle ligaments.…”

Lateral ankle sprains occur more than any other musculoskeletal injury in an athletic population. The greatest risk for an inversion ankle sprain is a history of a previous sprain. Recurring instability associated with subjective complaints of giving way is often termed chronic ankle instability (CAI). CAI has been associated with altered postural control, sensorimotor deficits, reduced physical activity, functional limitations, and long-term degeneration of the joint. Alterations, including muscle activity and changes in the kinematics of the lower extremity may predispose this population to continued instability at the joint and long term health issues. Common treatments include using external support, therapeutic modalities, and directed rehabilitation. Wearing ankle braces and performing balance training has been shown to reduce the risk of recurrent ankle sprains. Directed rehabilitation may improve function in patients with CAI. By identifying and minimizing dysfunction following ankle sprains, clinicians may improve the short-term and longterm function of this population.
