Ankle laxity affects ankle kinematics during a side-cutting task in male collegiate soccer athletes without perceived ankle instability.

This study examined how ankle looseness affects movement patterns in soccer players during cutting maneuvers. Researchers studied 66 male college soccer players who had previously sprained their ankles but didn't feel instability. They divided players into three groups based on ankle looseness: no laxity, moderate laxity, and severe laxity. Using motion analysis during a 45-degree side-cutting task, scientists discovered that players with severe ankle laxity showed significantly different foot movement patterns, particularly increased outward rotation of the rearfoot during most of the stance phase compared to those without laxity.

What does this mean for athletes? Even if your ankle feels stable after a sprain, underlying joint looseness may be changing how you move without you realizing it. These altered movement patterns could potentially increase your risk of future ankle injuries during sports activities involving cutting and pivoting movements.

While this study focused on biomechanics rather than treatment, it highlights the importance of addressing ankle laxity after injury. For patients considering complementary approaches to ankle rehabilitation and stability, acupuncture may offer supportive benefits alongside conventional physical therapy. Acupuncture has been explored for improving proprioception (body position awareness), reducing inflammation, and supporting tissue healing following musculoskeletal injuries. When combined with strength training and balance exercises, integrative approaches may help address both the structural looseness and neuromuscular control needed for ankle stability during dynamic movements.

If you're experiencing recurrent ankle issues or have a history of ankle sprains, finding a qualified acupuncture practitioner with experience in sports medicine can help you explore whether acupuncture might complement your rehabilitation program.

This cross-sectional study evaluated 66 male collegiate soccer players with prior ankle sprains but no perceived instability, stratified by ankle laxity severity: no-laxity copers (n=26), laxity copers (n=23), and severe-laxity copers (n=17). Using one-dimensional statistical parametric mapping during a 45° side-cutting task, researchers assessed hip, knee, ankle, rearfoot, midfoot, and forefoot kinematics throughout the stance phase. Significant differences emerged in horizontal plane rearfoot kinematics among groups during 30%-91% of stance phase (P<0.05). Severe-laxity copers demonstrated greater external rotation angles compared to no-laxity copers during 6%-14% and 32%-92% of stance phase (P<0.05). Clinical takeaway: Severe ankle laxity alters rearfoot mechanics during dynamic tasks even in asymptomatic individuals, suggesting compromised biomechanical control that may predispose to re-injury. Clinicians should address proprioceptive deficits and neuromuscular control in patients with documented ankle laxity, incorporating dynamic stability training regardless of subjective instability reports.
