After an injury such as a sprain or strain, proper rehabilitation is a must, especially when the injury has been severe. After acute treatment, a rehabilitation program is critical in speeding recovery of the joints, muscles and other tissue affecting functions.
Lack of rehabilitation can often delay return to normal function for months.
The other error most people make is to use prolonged immobilization. This usually leads to muscle atrophy and stiff joint.
The components of an effective rehabilitation for all sprain injuries include increasing range of motion and progressive muscle strengthening exercise.
