Subgroup analysis comparing response rates of clinicians vs. non-clinicians.
| Survey items with significant differences in response rates | Percentage of agreement | Statistics | ||
|---|---|---|---|---|
| Non-clinicians N = 16 | Clinicians N = 19 | Chi-square | p-value | |
| - sEMG is currently more relevant for researchers than clinicians | 93 | 53 | 6.42 | 0.01 |
| - Regarding the role of sEMG in patient's assessment. sEMG may be useful to evaluate the percent of maximal voluntary activation | 44 | 75 | 5.11 | 0.02 |
| - If a therapeutic intervention is administered. sEMG information may prove useful to track changes from baseline in muscular fatigue | 47 | 75 | 4.02 | 0.04 |
| - Score the utility of adding sEMG to the following techniques: | ||||
| Accelerometry | 57 | 90 | 4.31 | 0.04 |
| Goniometric assessment of the joint's active range of motion | 20 | 71 | 20.27 | <0.0001 |
| Stand-alone | 27 | 76 | 15.80 | <0.0001 |
| - To motivate and help patients learning motor strategies that satisfy a particular muscle activity goal, sEMG biofeedback may help them learning how to associate intrinsic kinesthesia with the desired movement. | 42 | 75 | 5.94 | 0.01 |
| - Judge the level of involvement of each of the following professionals for sEMG signal acquisition, processing and quality control: | ||||
| Clinical neurophysiologist | 31 | 53 | 4.08 | 0.04 |
| Physical Medicine and Rehabilitation physician, also known as physiatrist | 20 | 69 | 19.22 | <0.0001 |

| Occupational therapist | 27 | 13 | 4.10 | 0.04 |
| - Assuming proficiency with sEMG techniques, which of the following professions should provide education and training on the use of sEMG to neurorehabilitation professionals? Please judge the adequacy of the following professional figures: | ||||
| Clinical neurophysiologist | 96 | 56 | 6.06 | 0.01 |
| Physical Medicine and Rehabilitation physician, also known as physiatrist | 40 | 81 | 8.80 | 0.003 |
| - Based on your experience and knowledge. please score the relevance of the following elements as potential barriers to the clinical use of sEMG: | ||||
| Inadequate education for professionals in neurorehabilitation | 61 | 94 | 3.99 | 0.05 |
| Purchase and maintenance costs of sEMG equipment | 19 | 71 | 21.41 | <0.0001 |
