Active clinical trials for "Muscle Rigidity"

This is a randomized controlled clinical trial aimed at Parkinson's disease patients. Its objective is to evaluate the effects of a dynamic upper limb orthosis to achieve maximum hand functionality, reducing tremor and rigidity

The primary objective of this study is to apply a biomechanical system (the NeuroFlexor) associated with the EMG recording to study the physiological mechanisms that contribute to the regulation of muscle tone in healthy subjects and in patients with increased muscle tone. A second fundamental objective of this study is to monitor over time the changes in muscle tone that can be found physiologically in healthy subjects and pathologically in patients with spasticy and/or rigidity. A further objective of this study is the quantitative evaluation of the symptomatic effects of specific therapies in improving the impaired muscle tone. Clinical evaluation In this research project the investigators will recruit 20 patients with upper limb spasticity (regardless of the underlying disease responsible for the spasticity), 20 patients with Parkinson's disease characterized by stiffness of the upper limbs and 20 healthy control subjects. Patients will be recruited from the IRCCS Neuromed Institute, Pozzilli (IS). Participants will give their written informed consent to the study, which will be approved by the institutional ethics committee of the IRCCS Neuromed Institute, in accordance with the Declaration of Helsinki. All participants will be right-handed according to the Edinburgh handedness inventory (EDI) (Oldfield, 1971). Parkinson's disease will be diagnosed in accordance with the updated diagnostic criteria of the MDS (Postuma, RB et al. Validation of the MDS clinical diagnostic criteria for Parkinson's disease. Mov. Disord. Off. J. Mov. Disord. Soc. 33, 1601 -1608 (2018)., Nd). Clinical signs and symptoms of parkinsonian patients will be evaluated using the Hoehn & Yahr scale (H&Y), UPDRS part III (Patrick et al., 2001). The diagnosis of spasticity will be made through the neurological clinical evaluation of the patients and on the basis of the specific clinical history of the various pathologies underlying the spasticity itself (e.g. multiple sclerosis, stroke, spinal injuries). Spasticity will be assessed with the Modified Ashworth Scale "(MAS) (Harb and Kishner, 2021), the Modified Tardieu scale (MTS) (Patrick and Ada, 2006). Cognitive functions and mood, in both pathological conditions, will be evaluated using the clinical Mini-Mental State Evaluation (MMSE) scale (Folstein et al., 1975) and the Hamilton Depression Rating Scale (HAM_D) ( Hamilton, 1967). No participant must report pain problems and / or functional limitations affecting the upper limbs. Exclusion criteria: - insufficient degree of passive wrist movement (<30 ° in flexion and <40 ° in extension) - tension at rest during NeuroFlexor recordings - hand pathologies (neurological or rheumatological) - upper limb fractures in the previous six months - presence of peacemakers or other stimulators - pregnancy. All patients, and the group of healthy control subjects will have comparable anthropometric and demographic characteristics. Experimental paradigm Participants will be seated comfortably, with the shoulder at 45 ° of abduction, the elbow at 90 ° in flexion, the forearm in pronation and the dominant hand placed on the platform of the Neuroflexor device. Participants will be instructed to relax during the test session, which will consist of the passive extension of the wrist at 7 speeds, one slow (5 ° / s) and 6 rapid (50 ° / s, 100 ° / s, 150 ° / s, 200 ° / s, 236 ° / s, 280 ° / s). The total range of wrist movement will be 50 °, starting from an initial angle of 20 ° in palmar flexion up to 30 ° in extension. Before the start of the experiment, participants will do practical tests in order to become familiar with the device. Two slow and five rapid movements will be made for each speed. The different angular velocities of wrist mobilization will be randomized. Slow movements will be performed before fast movements with an interval of 10 seconds between each test. For each participant, a NC, EC and VC value in Newton will be calculated by a dedicated software. The resistance profiles will also be obtained when the device was running idle (without hand) to allow the biomechanical model to isolate the forces originating from the hand from the intrinsic forces of the device. For each movement, the corresponding surface EMG trace will have been recorded, by placing the electrodes on the skin overlying the belly of the FRC and ERC muscles. An accelerometer, fixed on the back of the hand of the limb to be examined, will be used to synchronize the electromyograph with the NeuroFlexor. The EMG activity recorded by means of surface electrodes with belly-tendon type mounting, will be amplified using the Digitimer, will then be digitized at 5 kHz using the CED, and finally it will be stored on a computer dedicated to offline analysis. EMG recordings will be made at 6 speeds, 50°/ s, 100°/ s, 150°/ s, 200 °/s, 236 °/s, 280 °/s. For each trace the following parameters will be analyzed: latency, peak-to-peak amplitude and area of the EMG response.

The application of a novel topical formulation for the treatment of muscular pain and stiffness (Egyfil), containing hyaluronic acid, SH-Polypeptide-6 and SH-Oligopeptide-1, is investigated to evaluate efficacy and safety in 26 patients with stiffness and pain. Single-Arm, Pre-Market, interventional study.

Purpose: In this study we wanted to compare bolus propofol and ketamine as an adjuvant to remifentanil-based total intravenous anesthesia for pediatric rigid bronchoscopy. Materials and Methods: Forty children under 12 years of age scheduled for rigid bronchoscopy were included. After midazolam premedication, remifentanil infusion 1 µg/kg/min was started and patients were randomly allocated to receive either propofol (Group P) or ketamine (Group K) and mivacurium for muscle relaxation. Anesthesia was maintained with remifentanil infusion 1 µg/kg/min and bolus doses of propofol or ketamine. After rigid bronchoscopy remifentanil 0.05 µg/kg/min was maintained until extubation. Hemodynamic parameters, emergence characteristics and adverse events were evaluated.

Stiff-man Syndrome (SMS) is a chronic, progressive disorder of the nervous system. It is associated with painful muscle spasms and rigidity involving muscles of the limbs, trunk, and neck. The cause of the disease is unknown, but researchers believe it may be a result of an autoimmune process. Patients with Stiff-man Syndrome may produce antibodies that attack enzymes required for the normal function of the nervous system. Steroids, plasmapheresis, and intravenous immunoglobulin (IVIg) have been given to relieve some of the symptoms of Stiff-man Syndrome. However, none of these therapies have proven to be significantly effective. This study will attempt to determine the effectiveness of intravenous immunoglobulin (IVIg) for the treatment of Stiff-mann Syndrome. Patients participating in this study will be divided into two groups. Group one will receive 2 injections of IVIg once a month for three months. Group two will receive 2 injections of placebo "inactive sterile water" once a month for three months. Following the three months of treatment, group one will begin taking the placebo and group two will begin taking IVIg for an additional 3 months. The drug will be considered effective if patients receiving it experience a significant improvement in muscle function, mobility, and stiffness.

The purpose of this study is to examine the influence of selective laser trabeculoplasty (SLT) on ocular rigidity in glaucoma patients.

Intensity is a "qualitative" variable of a muscle stretching protocol, which is very little studied due to its inherent characteristic of the individual being stretched. However, it was pointed out as an important factor for ADM gain. To verify the effects of different intensities of static passive stretching on flexibility, neuromuscular and functional performance in soccer athletes.
