Although SEMG is considered the gold standard for the objective assessment of muscle activation, its clinical use in our country is limited due to the high cost of specialized hardware and software. In contrast, diagnostic EMG devices are widely available in many healthcare institutions.\n\nThe research will be conducted on 30 healthy volunteers between the ages of 20 and 60. Participants will undergo lower extremity nerve conduction studies, reflex response measurements, and muscle activation assessments during voluntary isometric contractions of the m. tibialis anterior. Muscle activation will be recorded using the diagnostic EMG device via surface (adhesive and Ag\u002FAgCl coated) electrodes and needle electrodes. The acquired EMG signals will be analyzed in terms of RMS (Root Mean Square), amplitude, and frequency parameters.\n\nThe procedures performed within the scope of this study are standard practices carried out during routine EMG examinations. The only additional procedure specific to this research is the repetition of muscle activation measurements using different electrode systems. There is no invasive procedure involved in the surface electrode applications, and the needle electrode application will be performed exactly as it is in routine EMG tests. No serious risks are anticipated; rarely, mild pain, redness, or minor bleeding at the needle insertion site may occur.\n\nThrough this study, diagnostic EMG devices could be utilized more effectively in rehabilitation and treatment monitoring. It is intended to contribute to the reduction of invasive procedures and to establish a scientific foundation for clinical applications regarding the objective evaluation of muscle activation.",[27,28,29],"Healthy Volunteers (HV)","Muscle Activation","Electromyography",[31,32,33],"Surface Electrodes","Needle Electrode","Motor Unit Action Potential (MUAP)","NOT_YET_RECRUITING","2026-05-16",{"date":37,"type":38},"2026-05-20","ACTUAL",{"date":40,"type":21},"2026-04-24",{"date":42,"type":21},"2026-07-01",{"name":44,"class":45},"Romatem Bursa Hospital","OTHER",{"id":47,"slug":48,"hasResults":11,"nctId":49,"briefTitle":50,"officialTitle":51,"acronym":52,"eligibilityCriteria":53,"healthyVolunteers":15,"sex":16,"minAge":54,"maxAge":55,"enrollmentInfo":56,"targetDuration":4,"studyType":57,"phases":4,"briefSummary":58,"conditions":59,"keywords":60,"overallStatus":63,"whyStopped":4,"lastUpdateSubmitDate":64,"lastUpdatePostDateStruct":65,"startDateStruct":67,"completionDateStruct":69,"leadSponsor":71,"locationsCount":73},"100615835","latissimus-dorsi-activity-during-different-exercises-100615835","NCT07297771","Latissimus Dorsi Activity During Different Exercises","Investigation of Latissimus Dorsi Muscle Activation During Different Exercises","L-DORSI-EMG","Inclusion Criteria:\n\n* Age 18-40 years\n* No range-of-motion restriction at the glenohumeral joint\n* No shoulder, cervical, or lumbar region complaints\u002Finjury within the past 6 months\n* No systemic or neurological disease\n* Competent to consent and provides written informed consent\n* Tegner Activity Scale ≥ 5\n\nExclusion Criteria:\n\n* Body mass index (BMI) \\> 25 kg\u002Fm²","18 Years","40 Years",{"count":20,"type":21},"OBSERVATIONAL","This single-visit, laboratory study will quantify latissimus dorsi activation during standardized band\u002Fbody-weight exercises commonly used in rehabilitation (e.g., standing bent-over row, inferior glide, seated press-up, body-lifting). Healthy, physically active adults (18-40 y; Tegner ≥5) will perform three repetitions per exercise with metronome-paced phases (≈3 s concentric, 3 s isometric, 3 s eccentric), 5-s rest between repetitions and 2-min between exercises; load will be individualized to reach OMNI RPE 6-8. Surface EMG (TeleMyo DTS; Noraxon) will be recorded from the latissimus dorsi (medial and lateral) and selected synergists (teres major, infraspinatus, posterior deltoid, triceps); electrode placement will follow SENIAM recommendations. Signals will be band-pass filtered (20-500 Hz), rectified, RMS-smoothed with a 100-ms window, and normalized to %MVIC using standardized MVC tests; exercise\u002FMVC order will be randomized to limit bias.
