Filter by:The goal of this clinical trial is to compare the quality of mesoangioblasts isolated from various patient groups suffering from muscle atrophy. This study includes cancer cachexia and muscle-impaired elderly and a control group of the same age. The quality will be defined on these following outcomes: - The number and distribution of the mesoangioblasts in a muscle biopsy to define if there are sufficient mesoangioblasts to start a culture. - The proliferation capacity to define if we can culture them the numbers required for systemic treatment. - The myogenic capacity to define if the mesoangioblasts are sufficiently capable to generate muscle fibres. Participants will: - Undergo a muscle biopsy (needle biopsy or rest material from surgery, ~50mg) - Donate blood (~20 ml) - Fill in SARC-F questionnaire (evaluate sarcopenia score) - Fill in SQUASH questionnaire (evaluate physical activity of previous week) Researchers will compare groups (muscle-impaired elderly vs control; cancer cachexia vs control) to see if there is a difference regarding quality. These results will define the potential of autologous mesoangioblast therapy within these groups.
This trial will evaluate the impact of 6 weeks of postoperative essential amino acid (EAA)-based supplementation on muscle morphology after femoral fragility fracture. This trial will assess the ability of EAA-based to increase skeletal muscle metabolic activity, reduce inflammation, and induce muscle fiber hypertrophy, as well as preserve skeletal muscle mass and physical performance up to 6 months after injury. Participants will be randomized in a 1:1 ratio to 1) standard of care (no dietary intervention) or 2) EAA-based supplementation.
This study will incorporate patients/ caregivers' perspectives to investigate the performance in daily activities of individuals with SMA and how it relates to their motor function abilities.
Feasibility study of a new medical device that will evaluate the usability and effectiveness of a cycle ergometer device associated with neuromuscular electrical stimulation (FES cycling). The study's objective is to evaluate the effect of the application of functional electrical stimulation of the new device on participants' quadriceps muscle strength in comparison to a medical device with similar characteristics and to a control group. Secondarily, the study will compare the usability of the two medical devices as evaluated by the participants and the therapists who apply the treatment, as well as the participants' satisfaction with the treatment, identifying possible adverse effects.
The goal of this observational study is to to establish profiles of clinical progression in patients affected by the different types of SMA (type I, II and III) treated with the currently approved drugs using a structured battery of clinical tests. Another goal of the study is to assess the progression of the disease in patients identified through neonatal screening.
There is no complete cure for SMA yet. However, the discovery of the genetic cause of SMA has led to the development of several treatment options that affect the genes involved in SMA - a gene replacement therapy called Zolgensma, and two drugs, called Nusinersen (Spinraza) and Risdiplam (Evyrsdi). In this context, the evaluation of efficacy and the long term follow-up of patients treated with these innovative treatments in clinical routine is one of the critical points. These evaluations are carried out in a medical context (clinical sites or research unit) using validated measurement tools and outcome measures. Carrying out these evaluations in a controlled environment can be considered from certain aspects as an advantage (reproducibility of measures, neutral environment, etc.), but also raises a certain number of questions regarding the impact on patients, the financial cost, or the relevance of the data obtained in an unnatural environment (stress, fatigue, patient motivation…). Also the regulatory authorities ask for longitudinal data for deciding to reimburse these expensive treatments. As such, the hospital cannot digest all these evaluations due to a lack of resources.
The investigation will be conducted as a double blinded, randomized, parallel between treatment conditions comparison design with two different groups ingesting a different supplement each one.
The goal of this clinical trial is to compare the effects of resistance training (RT) preconditioning vs no training on disuse-induced atrophy and post-disuse resistance training in young healthy individuals. The main questions it aims to answer are: - To determine if performing RT prior to a period of disuse enhances the regain of strength, skeletal muscle size, and skeletal muscle quality while performing RT after a period of disuse. - To determine if performing RT prior to a period of disuse dampens the maladaptive effects of disuse on muscle size, muscle quality, and strength. - To determine the anabolic and proteolytic mechanisms underpinning the observed outcomes. Participants will: 1. Perform either 6 weeks of resistance training or maintain an untrained lifestyle 2. Perform 2 weeks of limb immobilization induced disuse of a randomized leg 3. Perform 6 weeks of resistance training Researchers will compare the resistance training preconditioning condition vs the non-trained condition to see if resistance training prior to a period of disuse is beneficial during the disuse period and in the return to training period on skeletal muscle size, strength, and underpinning molecular markers.
Objective: The aim of this study is to investigate the effect of motor imagery on muscle activity, pain, and function in arthroscopic rotator cuff repair. Methods: As a result of the power analysis (G-Power), 36 participants are planned to be included in this study Block randomization will be used to divide participants into 2 groups, each with at least 18 participants: Group 1 (MI group) and Group 2 (Control group) (Randomizer.org). Both groups will receive a 4-week physical therapy program. MI (Motor Imagination) group will receive a motor imagination program in addition to the physical therapy program. Data will collect using the visual analog scale (VAS), goniometric measurement, circumference measurement, Disabilities of the Arm, Shoulder, and Hand Questionnaire (DASH), Kinesthetic and Visual Imagery Questionnaire- KVIQ-20, Tampa Kinesiophobia Scale, 3-question satisfaction questionnaire, superficial Electromyography (EMG) (BTS Bioengineering Free EMG 100 RT). Practice Implications: The current study will contribute to understanding how motor imagination affects muscle activity and muscle atrophy.
The aim of the study is to measure and compare acute systemic irisin, myostatin and decorin levels after a single session of blood flow restricted resistance exercise and resistance exercise without blood flow restriction in healthy, trained male participants aged 18-35 years. For this purpose, a total of 22 people will be included in the study. Participants will be randomly allocated to 2 exercise groups as resistance exercise with blood flow restriction (BFR-RE) and resistance exercise without blood flow restriction (HL-RE) and will be subjected to cross-over. In the HL-RE intervention, the exercise will be performed with a loading of 80% of 1 RM, with 4 sets x 7 repetitions, with 60 seconds of rest between sets. In the BFR-RE intervention, the exercise will be done as a set of 30 repetitions with a loading of 30% of 1 RM and an additional 3 sets x 15 repetitions, with 30 seconds rest between sets. Total exercise volumes were tried to be equalized and skeletal muscle hypertrophy was selected in accordance with exercise guidelines. In both groups, bilateral leg extension exercise will be performed using the leg extension machine for resistance exercise. In the blood flow restriction group (BFR-RE), the cuff will be placed in the proximal region of the thigh bilaterally, inflated to a pressure equivalent to 50% of the estimated arterial occlusion pressure (AOP), and leg extension exercise will be performed under this condition. In the BFR-RE group, the blood flow restriction time will be between 5-10 minutes. Exercise sessions will be conducted under supervision. Venous blood samples will be collected from the arm antecubital region of the participants just before the exercise session, immediately after the exercise, and 1 hour after the exercise. Plasma irisin, myostatin and decorin levels will be measured from the samples taken. It is well known that resistance exercise is important in maintaining and increasing muscle mass (hypertrophy). Studies have shown the involvement of certain myokines in skeletal muscle hypertrophy, although few studies have been conducted on the systemic response of myokines to BFR-RE that may play a potential role in hypertrophy. Therefore, the planned study aimed to reveal the similarities or differences in the systemic myokine response between BFR-RE and HL-RE.
