NCT ID: NCT05754632 Recruiting - Knee Injuries Clinical Trials

The Impact of Blood Flow Restriction Training in Adolescents After ACL Reconstruction: A Randomized Controlled Trial

Start date: June 8, 2023
Phase: N/A
Study type: Interventional

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?

NCT ID: NCT05500872 Not yet recruiting - Clinical trials for Anterior Cruciate Ligament Rupture

Blood Flow Restriction After Anterior Cruciate Ligament Reconstruction (ACLR)

ACLR
Start date: August 30, 2022
Phase: N/A
Study type: Interventional

Muscle strength and muscle volume decrease rapidly with the immobilization process after sports-related injury and surgery. Depending on the decrease in muscle strength and muscle volume, functional performance also deteriorates, and this has been demonstrated by studies in the literature. Despite rehabilitation programs after anterior cruciate ligament surgery, muscle weakness persists for a long time and this affects knee functions. As a result, the time to return to sports is delayed or the activity level decreases. In recent studies, cross training is used to gain strength. Cross training is the increase in strength in the untrained leg after unilateral strengthening of the untrained leg. Another popular application for strength gain is exercise training with blood flow restriction. Blood flow restriction exercise training is an exercise protocol based on external pressure restriction of blood flow through the cuff from the proximal of the target muscle. It has been shown that this training prevents reduction of muscle volume in the early postoperative period and increases muscle strength. In the literature, cross-training and blood flow-restricted training are applied separately for muscle strength development after ACL reconstruction. However, no study investigating the effect of the combined application of these two approaches on muscle strength during ACL rehabilitation has been found. It is thought that with the combined application of these approaches, their effects on muscle strength development will increase, and accordingly, the functional results of individuals will be positively affected. The aim of the study is to determine the effect of cross training applied with and without blood flow restriction on muscle strength and function for 8 weeks starting from the 4th week after anterior cruciate ligament surgery. Participants will be included in the training for a total of 16 sessions, 2 days a week for 8 weeks. Pain, muscle strength, muscle thickness, knee functions will be evaluated before and after the training.

NCT ID: NCT05355922 Recruiting - Clinical trials for Osteoarthritis, Knee

Efficacy of the Aussie Current in Patients With Knee Osteoarthritis.

Start date: February 10, 2020
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT05184023 Active, not recruiting - Clinical trials for Anterior Cruciate Ligament Injuries

The Effect of PEMF for Patients With Quadriceps Muscle Weakness After ACLR

Start date: September 1, 2021
Phase: N/A
Study type: Interventional

In Hong Kong, over 3000 Anterior Cruciate Ligament Reconstructions (ACLR) are performed each year in order to restore knee function after an ACL injury. The ultimate goal of ACLR is to fulfil the return-to-play (RTP) criteria. Despite successful surgery and a demanding rehabilitation process, some athletes still fail to comply to RTP. For those who achieve RTP, 23% of those who return to their sports would suffer a second ACL injury. Quadriceps muscle strength is one of the key determinants for a patient's successful return- to-play after ACLR. 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. Therefore, there is need to find a more effective way to increase quadriceps strength. There are emerging evidences showing that pulsed electromagnetic field (PEMF) can modulate mitochondrial activities for muscle gain. PEMF exposure on top of regular exercise training may promote muscle regeneration and tissue healing. This study aims to conduct a double-blinded, randomized controlled trial to investigate the effects of PEMF treatment during the late postoperative period on quadriceps muscle strength in ACL injured patient. Muscle endurance could only be investigated in late postoperative period. The investigators hypothesize that PEMF treatment is effective to reduce muscle weakness and promote gain in quadriceps muscle strength in ACLR patients. Based on the aim of this study, adult patients (aged 18-30) with a unilateral ACL injury, total quadriceps muscle volume is equal or morn than 7% deficit on involved leg compared with uninvolved leg, sporting injury with a Tegner score of 7+, both knees without a history of injury/prior surgery will be recruited. To estimate the improvement of patients, Isokinetic muscle assessment, ultrasound imaging and MRI for quadriceps muscle thickness, self-reported outcomes with questionnaires, KT-1000 for knee laxity and biomechanical analysis, Xtreme CT for Bone mineral density will be performed. To investigate the mechanism of PEMF therapy on increasing quadriceps strength, samples of blood serum will be draw before and after intervention.

NCT ID: NCT05174611 Recruiting - Clinical trials for Anterior Cruciate Ligament Injuries

Vitamin D to Improve Quadricep Muscle Strength

Start date: March 19, 2021
Phase: Phase 2
Study type: Interventional

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?'
