Using the 180-degree system of recording,the starting position of normal joint motion is 0 degree.-30 to 0 to 35 indicates the degree of hyperextension below the 0-degree starting position.-30 to 0 to 35 indicates the ending degree of MP flexion.Average normal thumb MP ROM is 0 to 50,so the client has both abnormal hyperextension and limited flexion.
