Filter by:The goal of this trial is to learn about how restricted sleep and not bearing weight on the leg affects muscle strength and posture control. Participants will walk exclusively on one leg, sleep at differing intervals, and complete posture tests, muscle strength tests, and muscle imaging. Researchers will compare adequate sleep and restricted sleep to see if muscle strength and posture are affected.
The goal of this clinical trial is to compare two differential tourniquet pressure in lower extremity surgery cases. The main questions it aims to answer are: - What are the perioperative neurophysiological effects of ischemia and compression in the tissue under the tourniquet? - Are the effects of two different tourniquet pressures on neuromonitoring significantly different? - Can the ideal time of the reperfusion interval be evaluated by neuromonitoring? - Are the effects of two different tourniquet pressures on the quadriceps denervation significantly different from each other? Participants meeting the inclusion criteria will be evaluated for parameters to be used preoperatively. It will be evaluated in the 1st day, 1st week and 1-month follow-ups in the postoperative period. The investigators will compare two different tourniquet pressure ( Limb occlusion pressure +50 mmHg / + 100 mmHg) to see if it will be evaluated whether there is a significant difference in terms of quadriceps denervation, vas scores, total blood estimate volume loss, intraoperative MEP decrease, and recovery times, quadriceps tendon thickness, thigh circumfrences.
While there are a number studies that have reported on the use of blood flow restriction training (BFRT) in the adult population, there is limited information about the use of BFRT in the adolescent population. This study aims to evaluate the use of BFRT in conjunction with traditional anterior ligament reconstruction (ACLR) rehabilitation in adolescents. The purpose of this study is to compare the addition of a BFRT based exercise protocol to a standard ACL rehabilitation protocol in adolescents. Does the addition of BFRT-based exercise improve strength, hypertrophy, and patient reported outcomes after ACLR in the adolescent population?
The goal of this study is to compare quadriceps muscle activation in patients recovering from lower extremity injury, such as an ACL tear. Specifically, the main objectives are as follows: - Determine the effects of ankle positioning on quad muscle activation during straight leg raise exercises performed while the patient is lying on his or her back - Determine if there is a difference between ankle positioning on quad muscle activation during straight leg raise exercises performed while the patient is lying on his or her back, comparing healthy versus post-operative participants
Introduction: Osteoarthritis (OA) of the knee is a musculoskeletal disorder and is associated with significant implications related to public health and socioeconomic factors resulting in leave from work. Currently, there are several types of conservative treatment for this pathology, such as medications and mainly muscle strengthening, recommended by international guidelines. It can be associated with neuromuscular electrostimulation (NMES) as with the Aussie Current, for example, which aims to increase strength and function earlier. Objective: To determine whether the effectiveness of adding NMES to the Aussie Current in patients with knee OA who receive treatment based on the principles of conventional physiotherapy, in relation to pain relief, improvement of functional disability and muscle strength. Materials and Method: Forty individuals will be randomly distributed in two groups, with group 1 (G1) exercises and placebo application of electrostimulation and group 2 (G2) exercises and application of NMES with the Aussie current in the quadriceps femoris muscle. In the treatment, 24 sessions will be carried out in a period of 12 weeks based on the gold standard for the treatment of knee OA. Clinical outcomes of pain intensity, functional disability and muscle strength will be measured at baseline, immediately after 12-week treatment and after 24-week follow-up by a single blinded evaluator at all stages. All statistical procedures will be carried out following the principles of "intention to treat" and the comparison between groups will be carried out through the test of Mixed Linear Models. Expected Results: It is expected that there will be improvement in the variables: pain, functional capacity and strength in both the groups, however in the group that carried out the application of the Aussie Current, the gains would be more precocious, when compared to the group that did not carry out the NMES.
Quadriceps muscle strength is one of the key determinants for patients to fulfill the Return-to-Play (RTP) criteria after an anterior cruciate ligament reconstruction (ACLR), in which the muscle size is directly linked to muscle strength. Quadriceps muscle atrophy is unavoidable after ACLR, but the rehabilitation program should increase quadriceps muscle mass. However, despite good rehabilitation compliance, some patient's progress is sub-par and fail to regain muscle mass. Quadriceps muscle atrophy can persist beyond the completion of the rehabilitation program in almost half the patients and the reason behind this is still unknown. This represents an area that requires significant investigation, as quadriceps muscle atrophy and weakness have been shown to be determinants of poor knee function, decreased performance in sports and increased risk of reinjury. Quadriceps muscle atrophy after ACLR is well documented. This can be due to a decreased ability to regain muscle mass with rehabilitation. Athletes are one of the high-risk groups for vitamin D insufficiencies. Vitamin D deficiency can potentially result in decreased hypertrophy when exercising the muscle, leading to a poorer outcome in rehabilitation. Vitamin D has long been recognized for its effect on musculoskeletal health. It can have a direct effect on muscle hypertrophy by acting on specific vitamin D receptors (VDRs) on myocytes, and sufficient or increased levels of vitamin D in patients have been found to correlate with an increase in the size, number, and strength of muscle fibres. Quadriceps muscle hypertrophy after ACLR is triggered by exercise training, facilitated by diet and a number of intrinsic factors. As the rehabilitation programs and diets are similar in patients with varying extents of quadriceps muscle atrophy, individual responses (intrinsic factors) to exercise training may account for the resulting persistent quadriceps muscle atrophy. In this study, the investigators hypothesize that the deficiency of vitamin D may contribute to persistent quadriceps atrophy and weakness. With a stringent double-blinded randomized-controlled-trial (RCT) research design, our proposal will then address the research questions: 'Does vitamin D supplements improve the vitamin D deficiency status in patients after ACL reconstruction?', and 'Does vitamin D supplements improve quadriceps muscle strength for patients after ACLR?'
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.
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.
