Brief summary
Stroke is the leading cause of physical disability due to the presence of spasticity. Different needling techniques, including Botulinum Toxin A are proposed for management of spasticity; however results are conflicting. The presence of spasticity in the upper extremity implies several impairments for daily life activities. No study has investigated the effects of deep dry needling inserted into the targeted spastic musculature of the shoulder region in patients who had suffered a stroke. The investigators will conduct a randomized controlled trial investigating the effects of the inclusion of deep dry needling into a rehabilitation program over the musculature of the shoulder region, pressure pain hyperalgesia and range of motion in individuals with chronic stroke. The investigators hypothesize that patients receiving dry needling into the spastic shoulder musculature would exhibit greater improvements in spasticity, pressure sensitivity and range of motion than those who will not receive the intervention.
Interventions
OTHERDry needling
Patients will 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 pect
OTHERPhysical Therapy
Patients will receive 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

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Changes in spasticity before and after the intervention | Baseline and immediate after the interventionBaseline (1 week before) and 1 week after intervention | 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 |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Changes in pressure pain sensitivity before and after the intervention | Baseline (1 week before) and 1 week after intervention | 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. |
| Changes in shoulder mobility before and after the intervention | Baseline (1 week before) and 1 week after intervention | A universal goniometer will be used to determine the participant's shoulder range of motion in flexion, abduction and external rotation |
