Dry Needling for Spasticity in Stroke

Changes in Spasticity, Range of Motion and Pressure Pain Sensitivity in Patients With Stroke After the Application of Dry Needling in the Shoulder Musculature

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.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Experimental intervention; 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	Other: Dry 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; Other: Physical 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; Device: stainless steel needles (0.3mm x 50mm)
Active Comparator: Control intervention; 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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Changes in spasticity before and after the 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	Baseline and immediate after the interventionBaseline (1 week before) and 1 week after intervention

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Changes in pressure pain sensitivity before and after the 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.	Baseline (1 week before) and 1 week after intervention
Changes in shoulder mobility before and after the intervention	A universal goniometer will be used to determine the participant's shoulder range of motion in flexion, abduction and external rotation	Baseline (1 week before) and 1 week after intervention
