Active clinical trials for "Muscular Diseases"

Contemporary medicine lacks sensitive and objective diagnostic methods for the evaluation of patients with temporomandibular disorders (TMD). Shear wave sonoelastography allows for objective assessment of hardness, tone, and cohesiveness of tissues. Results are expressed in kilopascals (kPa) and can be compared at different time points in the same patient or between patients. The method is non-invasive and safe without any unpleasant experiences for patients. The project aims to evaluate the usefulness of shear wave sonoelastography in the diagnosis and monitoring of the management of masseter muscles disorders in TMD. The project will analyze shear wave sonoelastography to determine the pathological tone of masticatory muscles in TMD characterized by pain, abnormal jaw movements and frequent coexistence of headache, otolaryngological disorders, as well as increased tension and pain in the muscles of the neck and shoulder girdle. In the first stage, standardization of sonoelastography of masseter muscles on healthy subjects without TMD will be performed. Normal values of elasticity for various groups of patients as well as factors affecting the result of the study will be determined. Standardization will cover the methodology of the examination. The second stage will assess efficacy of this method in monitoring the treatment progress in patients with TMD diagnosed with the DC-TMD protocol. Standardized sonoelastography examinations and assessment of pain and oral health will be conducted in healthy subjects and in TMD patients at baseline and after 12 weeks of treatment with manual therapy and stabilization occlusal splint. As a result, it will be possible to compare sonoelastography changes in muscle structure in relation to regression of clinical symptoms in response to treatment and to compare sonoelastography results to currently used methods for assessment of TMD. The need for reliable determining of the sonoelastography values for diagnosis of TMD exist. The hardness of muscles of the human body vary, but norms for masticatory muscles remain undetermined. Available reports are inconclusive. They do not provide a methodology and do not address factors such as age, sex, examination at rest and during jaw-clenching. The present project eliminates those limitations, and as a result, contemporary medicine will get the basis for introducing sonoelastography for the diagnosis and monitoring of masticatory muscles disorders in various groups of patients.

Single-centre observational study over one year investigating the mechanisms of muscle homeostasis in patients with acute skeletal muscle atrophy following major aortic surgery

Quality of life (QoL) assessment is a milestone of clinical practice in gynecology. In particular, the use of validated QoL questionnaires is of the utmost importance for pelvic floor disorders, due to their functional nature and high prevalence. Pelvic floor dysfunctions such as lower urinary tract, bowel and sexual dysfunctions often coexisting with pelvic organ prolapse affect a substantial proportion of women and can often cause bothersome symptoms and have a negative effect on psychological and social well-being. Assessment of QoL in women with pelvic floor dysfunctions is essential for making a diagnosis and designating an adequate treatment. Therefore, it is necessary to evaluate women's subjective perception. A valid way to measure the patients' perspectives is through self-administered questionnaires that can address the presence and severity of symptoms, and their impact in daily activities and QoL. Symptom severity and QoL can be assessed by two specific questionnaires, the Pelvic Floor Distress Inventory (PFDI-20) and the Prolapse Quality of Life (P- QOL).

There is a significant proportion of patients complaining of muscle symptoms while on statin therapy who have a measurable difference in muscle strength or endurance and whose muscle biopsies are diagnostic for myopathy.

Statins (such as simvastatin or Zocor) are the most effective and widely prescribed medications to lower cholesterol levels and reduce the frequency of heart attacks, cardiac deaths and strokes. Unfortunately, statins can cause muscle discomfort or pain called "myalgia" in patients treated with these drugs. These symptoms often cause patients who need these medications to stop taking the drug. The cause of statin muscle pain is not known, but it is thought that a reduction of a vitamin-like substance called Coenzyme Q10 (CoQ10) during statin treatment may play a role. CoQ10 is a vitamin like substance and is not a drug approved and regulated by the Food and Drug Administration (FDA). This study will look at the effects of CoQ10 supplements on individuals who develop muscle symptoms while on simvastatin. The investigators hope to test the hypothesis that CoQ10 supplementation compared to placebo in patients with documented statin myalgia reduces the intensity of pain during statin treatment.

background: The Chronic Fatigue Syndrome (CFS) presents many disturbances multidimensional affect holistically to people who have the disease and current management of fatigue, pain, anxiety, depression and sleep disturbances present in this clinical entity is unsatisfactory. Hypothesis: The hypothesis of this essay is to contrast that acupuncture is more useful than placebo. The investigators suggest the use of a clinical study protocol (PEC), randomized, placebo-controlled, acupuncture technique, aimed at increasing the patient's sense of well-being, relief of pain and stiffness, acupuncture is effective to reduce fatigue, anxiety, depression and sleep disorders in patients diagnosed with CFS.

Skeletal muscle regenerates after injury, due to the satellite cells (SCs), the muscle stem cells that activate, proliferate, differentiate and fuse to form new myofibers. While SCs are indispensable for regeneration, there is increasing evidence for the need for an adequate cellular environment. Among the closest cellular partners of SCs are vascular cells. During muscle regeneration, endothelial cells (ECs) stimulate SC differentiation while SCs exhibit pro-angiogenic properties indicating a coupling between angiogenesis and myogenesis.The specific signaling cues controlling these relationships are still poorly characterized, specially in specific pathologic context such as limb ischemia. The investigators research aims to evaluate the role of chronic and acute lower limb ischemia on the SC status and interaction with ECs in human patients.

The purpose of this study is to investigate the mechanism of statin-related myopathy by evaluating muscle samples before and after statin exposure.

The researcher can use Diffuse Optical spectroscopy technique that uses harmless levels of near-infrared light to probe the concentrations and states of important physiological molecules such as hemoglobin water and lipids in human muscle,.

In addition to muscle thickness and average echo intensity, this study aimed to use quantitative ultrasonic technology to increase the number of related parameters of power Doppler ultrasonography measured to describe the number, quality, and recruitment level of muscles. In addition, this method was compared with the existing muscle strength testing methods. Image recognition was performed using the traditional multivariate linear regression statistical method and the AI convolutional neural network algorithm to investigate the application of quantitative ultrasonic technology for direct evaluation of muscle strength in clinical practice.
