Surface EMGs (sEMG) capture myoelectric signals of muscles closer to the surface of the skin.
Fine-wire EMGs are more intrusive in nature and less flexible, but are useful in the analysis of deep muscle activity.
Are there any studies that show that sEMG is much more preferred for practical diagnosis over Fine-wire EMG?
Apart from that, are Fine-wire EMG used for modern gait analysis at all? Or is it rarely ever used in this field?
As far as I know, sEMG is not yet officially introduced to the clinical routine, although some research on possible application of sEMG in clinics was published:

as my experience, it is so difficult to use fine wire EMG on patients for gait analysis because it would disrupt patient's real gait and consumes much more time than sEMG to attach and fix it. also, there is no need of this much precision in analysis. although, we have a lot of problems using sEMG for younger patients too....
