Risk factors

Factors contributing to sprains include:

• Environmental conditions. Slippery or uneven surfaces can make you more prone to injury.
• Fatigue. Tired muscles are less likely to provide good support for your joints. When you're tired, you're also more likely to succumb to forces that could stress a joint.
• Poor equipment. Ill-fitting or poorly maintained footwear or other sporting equipment can contribute to your risk of a sprain.
