How much space should there be between the axilla and the top of a crutch?

The recommended space between the axilla and the top of a crutch is typically 2-3 finger widths. This distance is crucial for proper crutch use because it allows the user to maintain comfort and proper posture while preventing pressure on the axillary region, which could lead to nerve damage or discomfort.

If the crutches are too high, it can cause the user to not use their arms effectively, leading to instability and increased risk of falls. Conversely, if they are too low, the user may experience irritation or injury to the underarm area. Therefore, ensuring a 2-3 finger space creates a balance that supports both safety and efficacy in mobility.
