简要总结
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 scientific event and a publication will be submitted to an impact journal.
KEY WORDS: Spasticity, H Reflex, Johnstone's Pressure Splint, Stretching, Functional Reach.

结局指标
主要结局
Reflex excitability of the flexor carpi radialis.
时间窗: before (baseline) and immediately after the intervention (maximum 10 minutes after the intervention).
Excitability is a specific property of muscle and nerve tissue and occurs when depolarization exceeds the threshold level in the action potential. The excitability will be measured from the evocation of H Reflex in the flexor carpi radialis muscle (FRC).
Muscular tone of wrist and elbow flexors.
时间窗: before (baseline) and immediately after the intervention (maximum 10 minutes after the intervention).
Defined as the resistance to movement of passive movement, it will be evaluated by the Modified Ashworth Scale (EAM) in flexo-extensors of the elbow and wrist and hand. (Ordinal scale of 6 points, with a range from 0 = normal tone to 4 = rigid segment in flexion or extension) .109 The EAM includes an additional degree of 1+, which has a sub-classification between an increase level and an increase of speed in the tone.
Joint kinematics in Functional Reach Pattern
时间窗: before (baseline) and immediately after the intervention (maximum 10 minutes after the intervention).
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.
