mechanical artifacts in surface EMG signal acquisition
Conditions
Interventions
Group 1: All participants undergo all test conditions. Each test subject is first tested without a box (NoBox) and then with a box (Box). In both conditions, defined disturbances (lateral and vertical

Inclusion criteria
Inclusion criteria: Inclusion Criteria: - Healthy adults (aged 18) with no known musculoskeletal disorders. - Ability to perform the required test movements (e.g., knee extensions, bending, lifting) without pain or discomfort. - No known neurological conditions affecting motor control or muscle activation patterns. - Ability to provide written informed consent and follow study instructions in English (or the language used in the study).
Exclusion criteria
Exclusion criteria: Exclusion Criteria: - Current or recent injury (within the past 6 months) to the lower limbs, trunk, or back that could impact muscle activation or movement patterns. - Any known allergy or skin sensitivity to adhesives or the materials used in the study (e.g., medical tape, electrode gels, TPU boxes). - Use of medications that significantly affect neuromuscular function (e.g., strong muscle relaxants, certain pain medications). - Inability or unwillingness to adhere to the study protocol or provide informed consent.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| sEMG signal quality: Reduction of mechanical artefacts in surface EMG (quantified by comparison of RMS values) between conditions without box and with box under standardised perturbation conditions. | — |
Secondary
| Measure | Time frame |
|---|---|
| Physiological parameters of the skin: Measurement of skin temperature and skin moisture before and after each condition to assess possible influences of the boxes on the skin physiology and thus on the EMG signal quality. | — |
