1. A system for measuring an angle of a joint of a user, comprising:
a center hub, the center hub having a first hub and a second hub;
a first coupling apparatus and a second coupling apparatus external to the center hub, each of the first coupling apparatus and the second coupling apparatus having a first layer and a second layer disposed above the first layer, wherein the first layer defines an area larger than an area of the second layer, and wherein the first and second coupling apparatuses are configured to be adhesively attached to first and second limb portions proximal to the joint of the user, respectively;
a first arm including a first outer end and a first inner end opposite the first outer end, wherein the first arm is attached to the second layer of the first coupling apparatus at the first outer end and the first arm is further attached to the first hub at the first inner end;
a second arm including a second outer end and a second inner end opposite the second outer end, wherein the second arm is attached to the second layer of the second coupling apparatus at the second outer end and the second arm is further attached to the second hub at the second inner end, and, further, wherein the first hub is pivotally coupled to the second hub;
a magnet coupled to the second hub;
a sensor configured to detect a rotation of the magnet; and
a transmitter configured to transmit an electrical signal based on the rotation of the magnet, wherein the electrical signal has data of the angle of the joint of the user.
