Results
The activity of the brachialis, a deep elbow flexor, was recorded using wire and surface electrodes, showing comparable patterns with both methods. This demonstrates that brachialis activity, previously considered difficult to assess from the skin surface, can be measured with surface electromyography. Moreover, the brachialis and biceps brachii exhibited distinct activity patterns during elbow flexion.

Baseline Characteristics
Healthy adult participants with normal elbow joint function
Participant flow
Healthy adult participants with normal elbow joint function were recruited. After the purpose and procedures of the study were explained, written informed consent was obtained. Wire and surface electrodes were then placed on the brachialis and biceps brachii muscles. The intramuscular insertion sites for the wire electrodes were identified using ultrasonography, and locations without adjacent blood vessels or nerves were selected. Following electrode placement, participants performed an elbow flexion task during which muscle activity was recorded. All electrodes were removed after completion of the task. In addition, a one-week observation period was established to monitor for any adverse symptoms following the experiment.
Adverse events
Nothing
Outcome measures
