Wobble boards are simple devices that are designed to challenge muscular strength and balance systems. The body is full of sensors called proprioceptors. These sensors relay information to the brain about where body parts are in space. They are most abundant in joints like the ankle and knee, and ankle or knee injuries can damage proprioceptors as well. Using a wobble board will help to retrain these receptors, improving coordination and reducing further injuries.
Step 1
Mark each side of the 2-by-2 foot plywood square at 12 inches and draw lines across the board to find the center of the board.
Step 2
Screw a wood screw halfway into the board at the intersection of the two lines and attach one end of the string to it.
Step 3
Attach the pencil to the other end of the string and rotate around the board to draw a circle on the board.
Step 4
Cut along the circle to remove the square edges of the board.
Step 5
Center the pipe flange in the center of the board. Attach the flange using wood screws.
Step 6
Screw the pipe cap onto the flange tightly.
Step 7
Sand the rough edges off the sides and top of the board, then apply grip tape on the top of the board to provide a stable place to stand.
Tips and Warnings
- A jig saw makes cutting the circular pattern easier. Using a power sander will make finishing the surface of the board easier.
- Always wear safety glasses when using tools to prevent eye injuries.
