The experimental intervention will consist of 3 sessions, one per week, of 45min of physical therapy including mobilizations of the scapular region, manual therapies targeted to decrease muscle tone, neuromodulatory techniques for spasticity and proprioceptive exercises for the upper extremity. In addition, during this intervention patients will also receive deep dry needling with disposable stainless steel needles (0.3mm x 50mm) that will be inserted into the skin over taut bands of the spastic musculature of the shoulder area: upper trapezius, subscapularis, infraspinatus, and pectoralis mayor

The control intervention will consist of 3 sessions, one per week, of 45min of physical therapy including mobilizations of the scapular region, manual therapies targeted to decrease muscle tone, neuromodulatory techniques for spasticity and proprioceptive exercises for the upper extremity.

Spasticity in the affected ankle joint will be evaluated with the Modified Modified Ashworth Scale (MMAS). The examiner passively moved the upper extremity in a stretching direction of each muscle (shoulder depression, shoulder external rotation, shoulder internal rotation, and shoulder abduction 90º combined with external rotation, respectively), back and forth at least 5 times and evaluated the degree of resistance to the movement on a scale from 0-4

Pressure pain thresholds, defined as the amount of pressure applied for the pressure sensation to first change to pain, will be assessed with a mechanical pressure algometer (Pain Diagnosis and Treatment Inc, New York, USA) unilaterally over the affected infraspinatus and deltoid muscles and bilaterally over the C5/C6 zygapophyseal joint.
