Effectiveness

How Dantrolene Sodium Affects Patients

Dantrolene is a drug that helps relax muscle contractions. It is the only known effective treatment for malignant hyperthermia, a condition caused by an abnormal reaction to certain drugs or anesthesia. In the body, it works by blocking the release of calcium from the muscles, which helps reduce muscle contractions. It is believed that this drug helps restore calcium levels in the body, which can help reduce the symptoms of malignant hyperthermia.

How Dantrolene Sodium works in the body

Dantrolene reduces the strength of muscle contractions by blocking a receptor in the muscles that helps control calcium levels. This reduces the amount of calcium available to help with muscle contraction, weakening the contraction overall.

When to interrupt dosage

The proposed dosage of Dantrolene Sodium is contingent upon the diagnosed condition, for instance Stroke, Spasticity and Spinal Cord Injury. The measure of dosage fluctuates in relation to the method of delivery (e.g. Capsule - Oral or Injection, solution - Intravenous) detailed in the table underneath.

Dantrolene Sodium for Muscle Spasms due to a Brain Disease

Though my neurologist said this medication is quite old, it works much better for me than a newer one I tried. I have MS and first started taking this in 2002; however, I began to experience more pain recently. Therefore, my doctor switched me to a different medication. After only one week on the new med, I changed back to Dantrolene because of the fatigue and pain it caused me. In comparison, Dantrolene allows me to function normally despite the minor pain it doesn't completely relieve.

Dantrolene Sodium for Muscle Spasm

Dantrolene has been an absolute lifesaver for me. I have MS, and while baclofen works sometimes, it's not always reliable. This drug has helped me get my life back on track; even though it made me drowsy at first, that effect went away after a little while and I felt like myself again. Just be sure to get regular liver tests done by your doctor.

Dantrolene Sodium for Muscle Spasms due to a Brain Disease

This drug has helped me a lot in the three weeks that I've been using it. Before, I was having spasms after my severe stroke which made it difficult to do simple things like moving my limbs. This medication relaxes my muscles so I can slowly but surely regain movement and function. Although there's no guarantee, I'm hopeful that within a year of continued use I'll be back to about 95% of what I was before the stroke happened.

Functional Balance Intervention for Multiple Sclerosis

40 - 90
All Sexes
Chicago, IL

The study involves a two-arm, Phase 1, randomized controlled clinical trial designed to establish the feasibility and effects of a Functional Balance Intervention (FBI) on physical and cognitive function, as well as measures of daily living among persons with multiple sclerosis (PwMS). Combined Specific Aims: Aim 1: Examine the effect of the FBI (Intervention Group) on physical function in PwMS compared to a stretching program (Control Group). Hypothesis 1: After four months of training, the FBI group will show significantly greater improvements in physical function compared to the stretching group. Aim 2: Examine the effect of the multicomponent FBI on cognitive function in PwMS compared to the stretching program. Hypothesis 2: After four months of training, the FBI group will show significantly greater improvements in cognitive function compared to the stretching group. Aim 3: Examine the effects of the multicomponent FBI compared to the Control Group among PwMS on measures of daily living (dual-task performance, balance confidence, community mobility, and quality of life). Hypothesis 3: After four months of training, the FBI group will show significantly greater improvements in measures of daily living compared to the stretching group. All assessment sessions will be conducted virtually via Zoom. All measures collected during the initial screening, pre-training assessment, training progression, and mid- and post-training assessment sessions will be administered either via Zoom with a Helper Buddy present or through survey links sent to participants via the UIC REDCap system. The training sessions will be performed independently by the participants in the presence of a Helper Buddy. The investigators will recruit 75 people with multiple sclerosis (PwMS) for this study. Eligible participants will be randomized to either the FBI (Intervention) or stretching (Control) group, followed by an onboarding session with a designated Helper Buddy. Training will occur twice weekly for four months. Based on the anticipated attrition rate, the investigators aim for 40 PwMS to complete the post-training assessments and finish the study.

Mindset Training for MS

18 - 65
All Sexes
Buffalo, NY

People with Multiple Sclerosis (MS) often experience cognitive difficulties such as memory problems, concentration issues, and reduced processing speed. These symptoms can have a negative impact on daily functioning and overall quality of life. Previous research on cognitive rehabilitation has shown that regular training focused on memory and concentration can have positive effects on cognitive functioning, including processing speed, memory, and executive functions that support daily activities. Moreover, fMRI studies (brain scans that measure brain activity) have revealed changes in brain activation following cognitive rehabilitation. Recently, the idea has emerged that a more personalized approach could improve treatment outcomes. Specifically, researchers have identified a link between personality traits and cognitive functioning. Since every individual is different, current cognitive rehabilitation programs often fail to take these personal differences into account. In this project, the investigators aim to enhance the effectiveness of cognitive rehabilitation by focusing more closely on individual characteristics through an app-based training program. Participants will complete a 12-week app training prior to a 6-week cognitive rehabilitation program. The first app focuses on mindset training, supported by a coach. Afterwards, all participants will use a second app designed to train processing speed and memory. In addition to cognitive functioning, the investigators will also examine psychological, (neuro)biological, and social changes using questionnaires and fMRI. This research may provide valuable insights into how cognitive functioning and quality of life in people with MS can be improved. This study is funded by the National MS Fund and is a collaboration between several institutions: the Department of Health, Medical and Neuropsychology at Leiden University (The Netherlands), the University at Buffalo (USA), and Reha Rheinfelden (Switzerland).

Paired Associative Stimulation + Locomotor Training for Spinal Cord Injury

18 - 75
All Sexes
Chicago, IL

Locomotor recovery is one of the most important goals of individuals with spinal cord injury (SCI). Ambulatory deficits severely impact daily functions resulting in lower quality of life for people living with paralysis due to SCI. Although studies have shown that locomotor training improves locomotor function in people with chronic SCI, the benefits remain limited. Our overall hypothesis is that we can engage additional descending motor pathways, such as the reticulospinal tract (RST), to improve locomotor function in humans with chronic incomplete SCI. In this study we propose to test the effects of a novel intervention that uses repeated paired loud auditory and electrical stimulation of muscle afferents combined with locomotor training on walking speed and voluntary muscle strength.

Pain Management Tools for Spinal Cord Injury

18+
All Sexes
Kelowna, Canada

Brief Summary The goal of this clinical trial is to evaluate whether a neuroscience-informed, peer-led self-management program can promote behavior change and reduce pain interference in adults with spinal cord injury (SCI) and chronic pain. The primary aim is to support participants in developing practical, sustainable strategies for managing chronic pain through education, reflection, and consistent application of self-management tools. The program is designed to shift participants from passive recipients of care to active agents in their own pain management process. Chronic pain is highly prevalent among individuals with SCI, and many report that traditional treatments - primarily pharmacological - provide limited relief and are accompanied by significant side effects. There is a growing need for accessible, non-clinical interventions that empower individuals to manage pain based on the latest neuroscience and behavior change principles. Solving SCI Pain intervention is a 7-week, multi-component program grounded in brain-based pain science, neuroplasticity, and behavior change models. The main questions it aims to answer are: * Does the intervention lead to meaningful changes in behavior that support pain self-management? * Does it reduce pain interference in everyday life? Participants will: * Attend three 2-hour group education sessions focused on the neuroscience of pain, the role of fear-avoidance, pain-related beliefs, and body-based self-regulation tools (e.g., movement, Graston, percussion massage, and red light therapy). * Participate in four individual coaching sessions (up to 1 hour each) designed to help them reflect on their experiences, overcome barriers, and integrate the tools into daily life. * Follow individualized coaching recommendations and provided resources to support each participant's unique engagement with cognitive and body-based tools over the 7-week period, including light journaling, goal setting, and guided reflections. * Complete brief check-ins every four days to monitor progress, engagement, and self-reported outcomes. Group and coaching sessions will be recorded and transcribed to support qualitative analysis, allowing researchers to understand how the intervention is experienced and delivered. This will help refine the program for future implementation and scaling. The study prioritizes accessibility, relevance, and peer involvement to address the real-world needs of individuals living with SCI and chronic pain.
