"Medical treatment" for the purpose of these regulations means any treatment intended to cure or improve the employee's physical or mental condition, including necessary prosthesis, made necessary by a compensable accident. "Rehabilitation" means the restoration to useful activity of injured employees who have reached maximum improvement with medical treatment. These reulations shall not be construed to be a limitation upon the injured employee's right to all reasonable and proper medical treatment. Ordinarily rehabilitation will be used to train injured employees, who are by reason of their injury precluded from returning to their usual occupation, to engage in other gainful occupations.
