Registered outcomes 3
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description | Source |
|---|---|---|---|---|
| Primary | Electromyographic activity | During each standardized dental maneuver | Electromyographic activity will be recorded using a Trigno Wireless surface electromyography (sEMG) system (Delsys, USA). Muscle activity will be assessed in the upper trapezius, deltoid, and erector spinae muscles during the performance of standardized dental procedures. Signals will be acquired at a sampling frequency of 2,000 Hz using EMGworks software. Maximum voluntary contraction (MVC) will be assessed through three 2-second contractions and will be used for normalization of the electromyographic recordings. | ClinicalTrials.gov |
| Primary | Posture | During each standardized dental maneuver | Posture will be assessed through video recordings obtained using four cameras positioned around the dental workstation (C1-C4). Participants will be recorded while performing standardized dental procedures on a phantom head. The recordings will be used to evaluate body posture during clinical performance, focusing on the positioning of the head, neck, trunk, and upper limbs. | ClinicalTrials.gov |
| Primary | Musculoskeletal symptoms | During each standardized dental maneuver | Musculoskeletal symptoms will be assessed using the Nordic Musculoskeletal Questionnaire, based on the instrument developed by Kuorinka et al. The questionnaire will evaluate the presence of musculoskeletal symptoms in 11 anatomical regions, including the neck, shoulders, upper back, lower back, elbows, wrists/hands, hips/thighs, knees, and ankles/feet. Participants will report the occurrence of symptoms during the specified recall period. | ClinicalTrials.gov |
