Study Arms (2)

I-ONE group

EXPERIMENTAL

The group will undergo home biophysical treatment with I-ONE® therapy (experimental group) for 4 hours/day for 60 days. Patients will follow standard rehabilitation treatment: patients will perform active and active-assisted range of motion (ROM) recovery exercises and stretching exercises for 30 minutes per day, for 6 weeks.

Device: I-One

Exercise group

NO INTERVENTION

The group, not subjected to biophysical therapy, will be controls. Patients will follow standard rehabilitation treatment: patients will perform active and active-assisted ROM recovery exercises and stretching exercises for 30 minutes per day, for 6 weeks.

Interventions

I-OneDEVICE

I-ONE® is a medical device certified by the Ministry of Health as a Medical Device (risk class II A) for the treatment of inflammatory and degenerative tissue pathologies. The device consists of a signal generator and an applicator, called a solenoid. The solenoid will be placed on the joint, not necessarily in direct contact with the skin. The device works with a rechargeable battery and is equipped with an hour counter to assess patient compliance. Treatment with I-ONE® therapy will start within 3-7 days of recruitment, will last 6 hours a day and will be maintained for 60 days. The treatment will be carried out at home and the device will be delivered directly to the patient's home by courier.
