R in the sustained modality.
This type of analysis was conducted on the data obtained in the sustained modality.
The interactions between Age and Precision are only significant in the sustained modality for reach time and the rate of failure.
The only dependent variable that showed a significant interaction between Age and Amplitude is the reach time (R) in the sustained modality in both the low and high precision conditions (Table 2; Fig. 3a).
Finally, the fact that the reach time in the sustained modality is compatible with the predictions of Fitts' law, whereas it is not in the impulsion modality, supports the view that the strategy for reaching a determined myoelectric amplitude is adapted to the final state: i.e. stabilization vs. immediate return to rest level.
In the sustained modality, the participant maintained the contraction after reaching the target so that the amplitude remained steady for one consecutive second.

However, simple arithmetic considerations discard this difference as a possible cause for the result: RT was smaller in the impulsion than the sustained modality (young: 840ms vs. 875ms; aged: 970ms vs. 1358ms), and taking the time of entry instead of the time of the first peak would cause an even greater difference.
Amplitude had significant effects on some variables (sustained modality: complete stabilization time in the low precision condition; impulsion modality: reach time in the high precision condition, and rate of failure in the high and low precision conditions; see Table 2), but no dependent variable increased monotonically as a function of amplitude.
The magnitude of the age effect on execution times is somewhat smaller (reach time, impulsion modality 14%, reach time sustained modality 43%, complete stabilization time 35%).
The latencies also increased as a function of Age (reach time, impulsion modality: 14%, reach time, sustained modality: 43%, complete stabilization time: 35%).
The joint effects of Age and Amplitude on all dependent variables in the sustained and the impulsion modalities are shown in Fig. 3.
