One prominent study found that immediate ice therapy "resulted in earlier return to activity, as defined by ability to walk, climb stairs, run and jump without pain."

Conclusion: joint mobilization combined with ice therapy for frozen shoulder can obviously increase the curative rate and improve the motor function of the shoulder joint.

Pettitte will be subjected to heat and ice therapy to make that possible, and the team is encouraged even by small signs such as Pettitte's ability to sit upright on the trainer's table.
