Stroke-related motor impairment
Conditions
Interventions
The intervention will consist in a unique treatment session (day). All subjects from both groups (healthy control and stroke patients) will be in a sitting position with their upper limb supported dur
Electrode positioning for recording of the surface electromyogram according to the Surface Electromyography for the Non-Invasive Assessment of Muscles (SENIAM) protocol for the biceps brachii muscle
Electromyographic signal acquisition during dynamometry
Needle insertion (45º angle) directed to the qi circulation with sterilized, disposable needles (0,20 x 13 mm) at approximately 1.5 cm deepth, followed by rotating maneuvers until the subjects reporte
At 5, 10, 15 and 20 minutes, manual stimulation will be performed during 10 seconds
After 20 minutes, the needle will be withdraw and the signal acquisition repeated.

Hemiplegic group: Clinical diagnosis of upper neuron lesion due to stroke for at least 6 months, confirmed by image exams, both ischemic of hemorragic; Partial motor impairment of the upper limb function (hemiparesis); Absence of pain, trauma or musculoskeletal injuries in the upper limbs, neuromuscular diseases, pregnancy or some sort of unconfortable reaction to needling; Informed written consent signature after reading of the text and explanation of the objectives, risks and potential benefits from the participation in this research.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Proportion of individuals with reduced muscle strength. Isometric muscle strength will be measured by the average of three maximal isometric voluntary contractions, each lasting 5 seconds, performed in the interval of 3 minutes each.;Proportion of subjects with reduced motor unit recruitment. Muscle recruitment will be measured by the average of RMS values of three maximal isometric voluntary contractions, each lasting 5 seconds, performed in the interval of 3 minutes each. | — |
Secondary
| Measure | Time frame |
|---|---|
| Prevalence of subtypes of clinical presentations according to Chinese medicine. Subtypes will be classified by multivariate logistic regression based on the reported symptons.;Prevalence of clinical manifestations in each subtype of clinical presentation. Clinical manifestations will be collected by interview with a clinical questionnaire. | — |
