Immediate Effect of Johnstone's Pressure Splint Added to Stretching on the Spasticity in Cerebrovascular Disease.

TITLE: Immediate effect of Johnstone's Pressure Splint added to Stretching on the spasticity of elbow flexors and wrist in Cerebrovascular Disease (CVD). INTRODUCTION: In the rehabilitation of the upper limb post-CVD to employed exercise modalities such as stretching (S) to control spasticity, improve mobility and functionality. Also it is used the Johnstone´s Pressure Splint (JPS), which exerts circumferential pressure and contribute to spastic pattern inhibition, sensory re-education and increased of the mobility. OBJECTIVE: The aim of the study is to evaluate the immediate effect of JPS added to S on the spasticity of elbow flexors and wrist, the reflex excitability and the joint kinematics in Stroke. MATERIALS AND METHODS: A randomized experimental study with two intervention groups will be performed. Control group (GS): Stretching and experimental group: (GJPS + S): JPS plus S. Measurement times: Before the intervention (T0) and immediately post- intervention (T1). The outcome variables are muscle tone of elbow, wrist and hand assessed with the Modified Ashworth Scale (MAS); H reflex of the Flexor Carpi Radialis muscle, latency (ms), duration (ms) and amplitude (mV) of the M and H waves, and the amplitude the Hmax / Mmax ratio (%). Shoulder, elbow and trunk angles (degrees), trunk displacement (cm) and duration (sec) of the Functional Reach Pattern (PAF) will be evaluated with the software Contemplas. ANALYSIS: Descriptive statistics will be applied and Shapiro Wilk test to evaluate the normality of the variables. Intra-group differences will be assessed with the student t-test paired and intergroup with the student t-test unpaired or the sum of Wilcoxon rank according to the distribution of the variables. EXPECTED RESULTS: Hypotheses and contributions to the scientific evidence on the immediate effect of the S and JPS will be generated, to support the JPS as a complement to the traditional treatment. The results will be socialized in an international scie
