神経生理学的ツールを用いて測定した錐体路関連痙縮患者におけるNMESの異なるパルス持続時間の有効性 (PD-NMES-SPAS)
神経生理学的ツールを用いて測定された、上位肢錐体路関連痙縮を有する患者における、高パルス持続時間と低パルス持続時間の神経筋電気刺激（NMES）の有効性：ランダム化比較試験
Spasticity is a common symptom that affects more than 50% of patients with upper motor neuron lesions due to damage on pyramidal tract. Despite the current pharmacological and physical therapy rehabilitation methods, previous studies have highlighted the beneficial role of Neuromuscular Electrical Stimulation (NMES) on managing upper limb spasticity. However, due to heterogeneity of application parameters there is a lack of a standardized protocol for spasticity management. The aim of the study will be to examine the effects of high versus low pulse duration neuromuscular electrical stimulation on upper limb spasticity on patients with pyramidal tract-related spasticity.
A total of 45 patients will be randomized (1:1:1 ratio) to either high pulse duration NMES (HPD-NMES) or low pulse duration NMES (LPD-NMES) or Control group, receiving the standard of care. Randomization will be performed by an independent investigator, who will allocate participants to one of three groups, using a random number generator, prior to baseline assessment. Each group will receive a 15min-conventional-physiotherapeutic protocol. HPD-NMES and LPD-NMES will receive an additional 30min-NMES protocol of high and low pulse duration, respectively. Pre and post intervention spasticity will be evaluated using Range of Motion (ROM) of the elbow joint through electronic goniometer, Modified Ashworth Scale (MAS) and surface electromyography (EMG). Furthermore, Modified Barthel Index (MBI) and 12-version of World Health Organization Disability Assessment Schedule (WHODAs) will be used for evaluating participants' quality of life. Statistical analysis will aim to highlight the effects of NMES both on the EMG-electrophysiological parameters and on clinical evaluation scales. Additionally, it will seek to determine which of the two NMES pulse durations produced more beneficial results in reducing spasticity levels.
調査の概要
状態
詳細な説明
Spasticity can be characterized as a clinical phenotype related to upper motor neuron syndrome and is highly correlated with pyramidal tract lesions, leading to patients' quality of life degradation. The assessment of spasticity encompasses both clinical rating scales (such as Modified Ashworh Scale, Modified Tardieu Scale and Composite Spasticity Scale) and neurophysiological approaches through surface electromyography (such as Hoffmann reflex (H-reflex) , Mwave, and Hmax/Mmax ratio (or M/H amplitude ratio), which seem to be elevated in spasticity. A wide spectrum of therapeutic modalities, including pharmacological and non-pharmacological interventions, have been developed for the management of spasticity. Among non-pharmacological interventions, physical therapy through Neuromuscular Electrical Stimulation can be used to manage upper and lower limb spasticity through the reduction of stretch reflex excitability, facilitation reciprocal inhibition and spinal excitability modulation.
This randomized controlled trial consists of:
- Participants randomization into one control group (group A, n=15) and two intervention groups: group B (High Pulse Duration Neuromuscular Electrical Stimulation/HPD-NMES, n=15), group C (Low Pulse Duration Neuromuscular Electrical Stimulation/LPD-NMES, n=15).
- Conventional Physiotherapy training program for 15 minutes per session, 3 times per week for 6 weeks total (groups A, B,C) and Neuromuscular Electrical Stimulation protocol for 30 minutes per session, 3 times per week for 6 weeks total (Group B=HPD-NMES and Group C=LPD-NMES)
- Primary spasticity evaluation tool at baseline and post intervention (6weeks) through surface electromyography.
- Secondary spasticity evaluation tools (Modified Ashworth Scale/MAS, Range of Motion/ROM, Modified Barthel Index/MBI and 12 version World Health Organization Disability Assessment Schedule 2.0/ WHODAS 2.0) at baseline and post-intervention (6 weeks).
Statistical analysis will aim to highlight the effects of NMES both on the EMG-electrophysiological parameters and on clinical evaluation scales. Additionally, it will seek to determine which of the two NMES pulse durations produced more beneficial results in reducing spasticity levels.

Changes in surface electromyography (EMG) parameters
時間枠：Baseline and 6 weeks
|
1. Changes in surface electromyography (EMG) parameters (Hoffmann reflex(H-reflex) of the flexor carpi radialis, M wave, F response of the median nerve, Hmax/Mmax ratio (or M/H amplitude ratio), motor unit number estimation (MUNE) and F response of the spastic upper limb). |

Modified Ashworth Scale
時間枠：Baseline and 6 weeks
|
1. Changes in Modified Ashworth Scale (MAS) scores. A 5-item evaluation scale that assessed muscle hypertonia. The minimum score is 0 (normal muscle tone) and the maximum is 4 (limb rigid). Higher scores indicate increase in spasticity. |
Baseline and 6 weeks
|
|
Range Of Motion
時間枠：Baseline and 6 weeks
|
Changes in Range of Motion (ROM) scores: The assessment will be conducted using an electronic goniometer to precisely determine the range of motion of the elbow joint affected by spasticity. Patients will be positioned in the supine position on the examination table with the affected side oriented toward the examiner. Then, the examiner will align the goniometer with anatomical landmarks the base of the goniometer over the lateral epicondyle of the humerus, the stable axis along the humerus and the movable axis along the radius. The angle of the elbow-flexion will be recorded, and the measured value will be substracted from 145o (the range of motion of a full elbow flexion) in order to calculate elbow extension. Decreases in elbow extension scores indicate reduction in spasticity levels. |
Baseline and 6 weeks
|
|
Modified Barthel Index
時間枠：Baseline and 6 weeks
|
Changes in Modified Barthel Index (MBI) scores. Modified Barthel Index is an evaluation scale that assesses patient's performance in activities of daily living. It consists of 10 domains with activities of daily living and mobility. Greater scores are correlated with decreased level of dependence |
Baseline and 6 weeks
|
|
World Health Organization Disability Assessment Schedule 2.0
時間枠：Baseline and 6 weeks
|
Changes in 12 version World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) scores: WHODAS 2.0 is an evaluation scale that assesses perceived disability associated with the health condition in the 30 days preceding its application. Is divided into six domains: i) cognition, ii) mobility, iii) self-care, iv) interpersonal relationships, v) activities of daily living and vi) participation. Each item is rated from 1 (no difficulty) to 5 (extreme difficulty or unable to do). Larger scores refer to larger disability. |
Baseline and 6 weeks

|
Changes in biceps brachii diameter (Ultrasound, objective measure)
時間枠：Baseline and 6 weeks
|
Biceps brachii diameter will be objectively assessed by standardized multi-mode ultrasound at baseline and in 6 weeks in all three study groups (HPD-NMES, LPD-NMES, and Control). The diameter's assessment will be measured on 90o elbow flexion and on 0ο extension.This non-invasive, safe and reproduciple measure requires minimal time and is conducted within scheduled study visits, without altering trial design, primary outcomes, or participant burden. |
