To measure for a push thumb brace like the MetaGrip, you need to measure the circumference of your hand just below your finger knuckles, excluding your thumb.
Proper sizing is crucial for the comfort and effectiveness of any thumb brace designed to support the base of the thumb (CMC joint), often referred to as a "push thumb brace". While specific measurement methods can vary slightly between manufacturers, a common technique, as described for the MetaGrip Thumb Brace, involves measuring the hand circumference.
Step-by-Step Measurement Guide
Follow these steps to accurately measure for a push thumb brace based on the provided reference:
- Gather Your Tools: You will need a flexible measuring tape (like one used for sewing) or a string and a ruler.
- Position Your Hand: Keep your hand relaxed and open.
- Locate the Measurement Point: Find the points on your hand just below the knuckles of your four fingers (index, middle, ring, and pinky). This is essentially the widest part of your palm, excluding the thumb area.
- Measure the Circumference: Wrap the measuring tape or string around your hand at this point. Ensure the tape is snug but not too tight, and that it lies flat against your skin.
- Read the Measurement: If using a measuring tape, note the measurement where the tape overlaps. If using a string, mark the point where it meets and then measure the length of the string with a ruler.
- Record the Measurement: Note the measurement in inches or centimeters, depending on the brace manufacturer's sizing chart requirements.
Key Point: The reference states, "To determine the proper sizing of the MetaGrip Thumb Brace, measure the circumference of your hand just below the knuckles of all fingers, excluding the thumb." This measurement helps match your hand size to the available brace sizes (which are typically offered in multiple sizes for both the right or left hand).
Why This Measurement Matters
This specific measurement point provides a reliable indicator of your hand's overall width and circumference across the palm. Brace manufacturers use this to correlate with the internal dimensions of the brace, ensuring a secure yet comfortable fit around the hand portion, which is essential for stabilizing the thumb joint effectively without restricting necessary movement or causing pressure points.
Sizing Information (Example Structure)
Brace sizing is usually determined by matching your hand circumference measurement to a specific size category (e.g., Small, Medium, Large). Always refer to the specific sizing chart provided by the manufacturer of the brace you intend to purchase.
| Size | Hand Circumference (inches) | Hand Circumference (cm) |
|---|---|---|
| Small | [Range e.g., 6" - 7"] | [Range e.g., 15 cm - 18 cm] |
| Medium | [Range e.g., 7" - 8"] | [Range e.g., 18 cm - 20.5 cm] |
| Large | [Range e.g., 8" - 9"] | [Range e.g., 20.5 cm - 23 cm] |
Note: The size ranges in the table are illustrative examples. Always use the official sizing chart for the specific brace model.
Taking this simple measurement correctly ensures you select the appropriate size for optimal support and comfort from your push thumb brace.
