However, they did find differences in muscle activation sequence by position [ 11].
The versatility of waveform comes from the intrinsic difference of skin resistance, muscle activation sequence, and motor unit mass.
This pattern of EMG activation means that the normal distal to proximal muscle activation sequence is reversed and that contraction of the hip muscles precedes that of ankle muscles thus increasing the limb stiffness and inducing lack of appropriate corrective movements.
To the best of our knowledge, these are the only studies that have investigated the role of ankle bracing in lower limb muscles activation sequence, and therefore further research is needed.
Some weak points are noteworthy in this study: (1) there is a lack of data concerning the position of the scapula before and after the rehabilitation, (2) testing was carried out by only two examiners and this might be a limit for the study realibility, (3) analysis of the scapular-stabilizing muscle patterns activation sequences was not performed.
The mirror transfer test required the same pattern of homologous muscle activation and a sequence of joint angles as experienced during the acquisition phase, and the non-mirror transfer test required the same visual-spatial pattern as performed or observed during acquisition.
Here, coordination concerns primarily the adjustment of both timing and sequence of muscle activation to enable smooth, effective jaw and tongue movements.
Increased muscle preparatory activity and muscle activation have also been found, leading to plyometrics possibly even preventing injury [20].
Reasonably, abnormal generation of motor patterns, such as delayed onset of muscle activation, inappropriate amplitude, and reversal of the normal activation sequence produce less effective correction of destabilized posture.
The time sequence of the finger muscle activation predicted in the current study is consistent with the EMG data in the literature.
