View clinical trials related to Quadriceps Muscle Atrophy.
Filter by:Introduction: Approximately 35% patients can not return to sports after anterior cruciate ligament reconstruction(ACLR). Persistent quadriceps weakness is a factor that prevents patients return to sports. Pre-operative quadriceps strength is a predictor for the outcomes after ACLR. Therefore, enhancing pre-operative quadriceps is important. However, current prehabilitation can not well restore quadriceps strength may be due to quadricep inhibition. Whole body vibration was proposed as a promising intervention to increase muscle strength and modulate quadriceps inhibition simultaneously. Therefore, this study aim to investigate if whole body vibration has the efficacy of enhancing pre-operative quadriceps and modulating quadricep inhibition in patients with ACL injuries. Methods: A randomized controlled trial was designed. Patients with primary ACL injuries, age from 18-45 yrs, BMI<29, physically active who awaiting ACLR will be included. Patients with any previous lower-limb injuries within 1 year, any cardiovascular or metabolic disorders will be excluded. All the subjects in this study have to finish their routine 5 week prehabilitation as well as the interventions. The primary outcomes of this study include quadriceps strength and quadriceps central activation ratio. Secondary outcomes include the score of IKDC and ACL-RSI, as well as the concentrations of myokines in serum.
The goal of this randomized clinical trial is to evaluate the effects of vibration on factors related to the risks of post-traumatic knee osteoarthritis and secondary anterior cruciate ligament (ACL) injury in individuals who have undergone anterior cruciate ligament reconstruction surgery (ACLR). The main objectives are to compare the effects of Standard rehabilitation vs. rehabilitation that includes whole body vibration (WBV) or local muscle vibration (LMV) on: - Quadriceps muscle function - Gait biomechanics linked to post-traumatic knee osteoarthritis development - Patient self-report outcomes - MRI indicators of knee joint health and muscle quality - Landing biomechanics linked to secondary ACL injury risk - Evidence-based return-to-physical-activity criteria Participants will be assigned to 1 of 3 groups (standard rehabilitation, standard rehabilitation + WBV, or standard rehabilitation + LMV) and will complete assessments of quadriceps function, gait biomechanics, landing biomechanics, functional ability, patient-report outcomes, and MRI 1, 6, and 12 months after ACLR. Researchers will compare the groups to see if vibration embedded in ACLR rehabilitation improves joint health outcomes.
Quadriceps femoris (QF) atrophy is seen in rheumatoid arthritis and knee osteoarthritis (OA) patients. Exercise therapy is mile stone in knee OA patients also it can help thicken QF muscle of RA patients. We primarily aimed to demonstrate the influence of 4 weeks of knee isometric home-based training on QF muscle parts thickness and pennation angle measurements of RA patients with ultrasonography (USG). This study included 12 patients with RA, 12 patients with knee OA as positive control group and 13 volunteers as healthy control group. All participants were given 4 weeks of quadriceps-hamstring isometric home-based training. At baseline and at the end of the program, WOMAC and Lequesne algofunctional index scores of knee OA patients and DAS28-CRP scores of RA patients were recorded. Dominant knee thickness and pennation angle measurements of QF muscle parts were evaluated by ultrasonography.
ICU-Aw is highly prevalent (50%) among critically ill patients. Its diagnosis is usually delayed as it requires patients' awakening and collaboration to provide accurate measurement. This study aims to investigate the accuracy of an early ultrasound measurement of quadriceps shortening during neuromuscular electrical stimulation to diagnose future ICU-Aw in critically ill patients.
The reverse Nordic curl is a body-weight exercise which mainly works the quadriceps and hip flexors. It has a large eccentric component, meaning the muscles are working whilst lengthening. The purpose of this study is to investigate the effect of the reverse Nordic curl exercise on Quadriceps femoris muscles injuries among soccer players. It hypothesized that reverse Nordic curl exercise has a beneficial effect in terms of Quadriceps femoris muscles injury prevention.
The purpose of this study is to investigate the neurophysiological contributors to muscle function following ACL Reconstruction and the influence of motor control biofeedback exercise on measures of muscle function. The research team hypothesizes that the application of motor biofeedback will increase cortical excitability of the quadriceps compared to the passive movement of the knee. This is a single session cross-over intervention study with a 1-week washout period between treatment arms.
Postoperative protocols for orthopedic procedures on the lower limb often require a period of immobilization to protect the surgical site. The consequence of this immobilization is muscle atrophy which can be severe, delaying a patient's return to activity and predisposing them to recovery complications or subsequent injury (1)(2). The current standard methods to assess lower limb muscle atrophy all have their respective limitations. Thigh circumference or isokinetic strength values are indirect measures of atrophy and can be inaccurate. Magnetic resonance imaging (MRI) of muscle cross-sectional area (CSA) is time-consuming and expensive. Computed tomography imaging of muscle CSA is expensive and exposes the patient to radiation (3). For these reasons, none of the current methods are ideal for regular use in the clinic. Musculoskeletal ultrasound is a promising measurement tool to assess muscle atrophy in postoperative patients. Ultrasound is non-invasive, cost-effective, does not involve radiation, and can give direct images of muscle size (4). Musculoskeletal ultrasound requires further research on its potential as an evaluation tool for postoperative lower limb orthopedic patients-specifically, whether ultrasound is a reliable and valid tool for quadriceps size measurements.
The purpose of the study is search the interrater and intrarater reliability of the quadriceps muscle using rehabilitative ultrasound imaging and search for an association between sarcopenia and quadriceps muscle in poststroke patients.
This study is a prospective, double-blinded, randomized control trial examining the effect of blood flow restriction (BFR) therapy on reducing post-operative quadriceps atrophy in patients undergoing anterior cruciate ligament reconstruction (ACLR). Following ACLR, patients will undergo a rehabilitation protocol either w/ BFR therapy or sham BFR therapy.
Patients admitted to the ICU with diagnosis of sepsis and requiring mechanical ventilation for at least 24-hours and receiving enteral or parenteral nutrition will be prospectively randomized to one of two arms. Patients allocated to the estimated energy expenditure group will receive nutrition with caloric intake calculated based on the Penn State equation. Patients randomized to the measured group will receive nutrition with caloric intake calculated based on IC measurement present in the GE ventilator. Patients in the estimated group will have IC performed, but these data will not be used for prescription of nutrition. An equal number of beds within the ICU will be allocated to the measured group and the estimated group. The primary objective is to assess whether the utilization of indirect calorimetry for caloric goal calculation results in improvement in muscular structure, and consequent reduction of mechanical ventilation duration in patients with sepsis in comparison to utilizing the Penn State estimation equation for caloric goal calculation. The secondary objective is to assess whether the utilization of indirect calorimetry for caloric goal calculation results in improved adequacy of nutritional delivery in comparison to the adequacy of nutritional delivered when utilizing the Penn State estimation equation. Adult patients (> 18 years of age) admitted to the hospital with diagnosis of sepsis, and who require mechanical ventilation during hospitalization will be considered. Patients newly ventilated for at least one day but less than three days will be included in the study. Informed consent will be obtained from the legal authorized representative (LAR).
