Electromyographic power spectrum changes
| Band (Hz) | Maintained posture and ischaemia | Posture-relax-posture | ||
|---|---|---|---|---|
| Mean | SD | Mean | SD | |
| The figures are the percentage values where the baseline electromyographic spectrum power has been set to 100% in each of the three bands. Data from the six subjects were combined. None of the bands is significantly different from the baseline in the maintained posture and ischaemia condition or in the posture-relax-posture condition (paired t tests). | ||||
