Effectiveness of Dry Needling for Improving Gait in the Patient With Multiple Sclerosis (DRYNEEDEM)

Analysis of the Effectiveness of Dry Needling for Improving Gait in the Patient With Multiple Sclerosis: a Randomized Single-blind Clinical Trial

Multiple sclerosis (MS) is a chronic, inflammatory, autoimmune disease characterized by the appearance of lesions, characterized by heterogeneity in its pathological, clinical and radiological presentation. It has a significant socioeconomic impact, affecting interpersonal relationships and causing a significant reduction in quality of life. Patients with MS suffer from a series of symptoms (ocular, spasticity, cerebellar, sensory, fatigue, depression) that may be independent of the course of the disease and their management significantly influences quality of life and also requires multidisciplinary therapeutic measures. Physiotherapy and occupational therapy techniques are essential to reduce spasticity and prevent complications derived from it. Amongst physiotherapy techniques, we can find minimally invasive techniques such as dry needling which uses a fine filiform needle to penetrate the skin and mechanically break the myofascial trigger points, charactewrized by abnomral/pathological electrical activity. There have been previous studies with dry needling in stroke patients which have shown improvements in gait, but its effectiveness in other populations such as multiple sclerosis is still unclear. In addition, dry needling has proven to be a cost-effective treatment for spasticity in patients with chronic and subacute stroke and could be an alternative to other pharmacological treatments, although more studies are necessary to compare both the effectiveness and the cost-effectiveness . Recent studies carried out in patients with multiple sclerosis suggest that dry needling can improve mobility and gait speed. The main objective of the study is to analyze the effect of the application of a single session of dry needling in the lower limbs on the gait of patients with multiple sclerosis. A prospective randomized parallel group clinical trial with blinded outcome assessment will be conducted. Participants will be recruited from the Hospital Universitario de Canarias.

The intervention group will have a single session of dry nedling application in the medial gastrocnemius + usual care (physiotherapy)

The control group will have a single session of sham dry nedling in the medial gastrocnemius + usual care (physiotherapy)

is a quantitative mobility and leg function performance test based on a timed 25-walk. This is considered the "gold standard" to assess gait speed in MS patients. The test measures the time in seconds that the patient needs to walk 25 feet (7.5 meters).

is a self-report measure of the impact of MS on the individual´s walking ability. Each item is scored from 1 (no limitation) to 5 (extreme limitation), with a total score ranging from 12 to 60, where higher values show higher impairment . MSWS-12 scale shows properties which make it suitable for use in clinical practice, concretely for patients with medium-to-high levels of walking disability

was designed initially to measure the probability for falls among older adults, but has been validated also for other populations such as MS. For this test, the participants sit in a chair with their backs supported by the back of the chair and their arms resting on the armrests. The participants are asked to get up from the chair and walk a distance of 3 me-ters, to turn on themselves (360°) and walk back to the chair and sit down again. The TUG test has demon-strated to be highly reliable and responsive in the assessment of respectively the walking capacity and general mobility of patients with MS with mild disability

This is a specific quality of life questionnaire for MS. This is a self-assessment question-naire composed of 54 items, divided in a physical and mental domain. The range goes from 0 to 100, where 100 is the highest degree of quality of life. The Spanish version of the MSQoL 54 instrument has shown to be a valid and reliable instrument for measuring qual-ity of life in patients with MS
