Etidronic acid

The Generic name of this drug

Treatment Summary

Etidronic acid is a medication used to regulate the calcification and decalcification of bones. It is a first generation bisphosphonate, similar to clodronic acid and tiludronic acid. Etidronic acid was approved by the FDA in 1977, but over the years it has been replaced by newer, more effective third-generation nitrogen-containing bisphosphonates such as zoledronic acid, ibandronic acid, minodronic acid, and risedronic acid.

Effectiveness

How Etidronate Disodium Affects Patients

Etidronic acid is a drug that stops the body from reabsorbing bones. It is generally safe and produces long-lasting effects. However, patients should be warned about potential side effects in the upper digestive tract.

How Etidronate Disodium works in the body

Bisphosphonates work to stop bone from being broken down. When they enter the bone they attach to hydroxyapatite and are released when the acidity level changes. The bisphosphonates then enter the osteoclasts, which normally break down the bone. The bisphosphonates disrupt the action of osteoclasts by blocking the ability of the cells to create ring-shaped structures of F-actin. This prevents them from breaking down the bone and stops bone resorption. First generation bisphosphonates also prevent osteoclasts from using ATP, which further stops the process of bone res

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.

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.

Motor Evoked Potential Conditioning for Spinal Cord Injury

18+
All Sexes
Charleston, SC

The purpose of this research study is to examine the effect of a brain stimulation training to improve the function of brain-spinal cord- muscle connections. Because brain-to-muscle pathways are very important in our movement control, restoring function of these pathways may improve movement problems after injuries. Spinal cord injury causes damage to the brain-to-muscle connection. However, when the injury is "incomplete", there is a possibility that some of the brain-to-muscle pathways are still connected and may be trained to improve movement function. For examining brain-to-muscle pathways, investigators use a transcranial magnetic stimulator. Investigators hope that the results of this research study will help us develop new treatments for people who have movement disabilities. This study will require about 42 visits over the first 14 weeks, and another 6 visits over an additional 3 months. Each visit will take about 1 ½ hours.

Surgical Treatment for Ankle Equinus

4 - 17
All Sexes
Edmonton, Canada

Tight ankle muscles can produce ankle equinus (limited ability to pull the foot upward) and occur often in children, significantly impacting their ability to walk. If not treated, children with ankle equinus frequently experience reduced function and long-term foot problems, such as pain. Currently, treatment options include surgery or Botulinum toxin (BoNTA) injection into the large calf muscles that point the foot downwards, aiming to reduce their tightness. However, these treatments can be less effective over time, can create prolonged calf weakness, and may require long-term bracing. Another small muscle in the leg, the plantaris, is believed to have some contribution to equinus in many children. It is sometimes included in treatment plans for equinus but its contribution is poorly understood. It is unclear whether targeting the plantaris alone could lead to better treatment of ankle equinus. Understanding the effect of treatments targeting the plantaris could help clinicians improve the management of ankle equinus. In this study, the investigators will look at the impact of surgical treatment to the plantaris in ankle equinus. The investigators hypothesize that the plantaris is a significant contributor to equinus. In this study, data will be collected from children undergoing surgical correction of ankle equinus, including lengthening of the plantaris and lengthening of the larger muscles producing equinus (the gastrocsoleus mechanism). Children will be randomly assigned to have either their plantaris or the gastrocsoleus lengthening be done first during surgery. All children will have both structures lengthened during surgery, only the order will be varied and all surgical procedures for each patient will be completed in a single setting. In both groups, maximum passive ankle dorsiflexion (upwards bend of the ankle with the knee straight) will be measured before and after each structure is lengthened. The outcome is maximum passive ankle dorsiflexion (upwards bend of the ankle) with the knee straight. The investigators expect that maximum passive ankle dorsiflexion will increase after lengthening of the plantaris. Understanding the contribution of the plantaris muscle in ankle equinus could lead to significant improvements in the treatment of children with tight ankles.
