An interventional study of Manual therapy and Placebo in Healthy, sponsored by Medical University of Gdansk. Not yet recruiting. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2024-12-24.
Sponsored by Medical University of Gdansk · Not applicable, Interventional, and Prevention
The aim of this study is to: (i) characterize the effect of repeated archery shots on the EMG parameters of certain selected upper limb muscles; and (ii) evaluate how manipulation of the initial two-second tension phase, in particular involving muscle stretching, affects these EMG parameters after repeated shots.
EMG measurements will be collected for selected muscles in the shoulder joint and forearm, at points: initially at the beginning, after the athletes have performed 50 and another 50 archery shots, and finally after undergoing manual therapy. The main phase of muscle testing will take place in the Aiming phase.
Medical University of Gdansk is the lead sponsor of 130 studies on the registry; 46 are open to participants now.
Counted across the registry records on this site, refreshed daily.
Exclusion Criteria:
Performing the manipulation with a preliminary two-second tension of the joint capsule in the shoulder and elbow joints.
Other: Manual therapy · Other: Placebo
This technique involves a low-amplitude, high-velocity push on the shoulder and elbow joints with an additional two-second tension
Performing manipulations without a two-second preliminary tension of the joint capsule in the shoulder and elbow joints.
Assessment of MVC.
Muscle EMG is an assessment of the electrical characteristics during the study, the electrical source of which is the muscle membrane potential, and the measured EMG potentials are measured in μV and the repetition rate of muscle motor unit firing measured in Hz, at the same time of the study.
Time frame: Each isometric muscle test lasts 3 seconds. The study is performed three times for each muscle.
Muscle stiffness
Muscle stiffness - characteristic resistance to physical contraction, which deforms initially forming. Stiffness (N/m) was calculated as S = amax.mprobe/Δl.
Time frame: Each Myoton application lasts 1 sec for one point. Three evaluations of one of the two points for one muscle are performed. It is assumed that the study with recording will last 30 seconds for one muscle.
No study locations are listed for this record.
