Table 1. Technical characteristics of the automated cyclic stretching controller.

	Range of values	Extreme values	Precision
Basal tone, g	1–3	0–12	0.001
Maximum developed tension, g	2–7	0–12	0.001
Speed of linear displacement, mm/sec	1–1.25	0.75–1.25	0.10
Measurement frequency (Hz)	10	0.1 to 60	not applicable

The "extreme values" and "precision" correspond to data provided by the device's manufacturer. The "range of values" corresponds to the experimental range chosen by the investigators with a view to optimizing feasibility and facilitating data collection.
