Finds the maximum gravity-corrected torque. For isokinetic trials with an
angular-velocity trace, the search is restricted to samples within
velocity_tol of the target velocity so acceleration and deceleration
transients do not determine the peak.
Usage
peakTorque(
torque,
sampling_rate,
mode = c("isokinetic", "isometric"),
angle = NULL,
angular_velocity = NULL,
target_velocity = NULL,
velocity_tol = 0.1,
at_angle = NULL,
gravity = NULL
)Arguments
- torque
Numeric torque trace in N m.
- sampling_rate
Sampling rate in Hz.
- mode
Either
"isokinetic"or"isometric".- angle
Optional joint-angle trace in degrees.
- angular_velocity
Optional angular-velocity trace in degrees/s.
- target_velocity
Optional target angular velocity in degrees/s. The largest observed absolute velocity is used when omitted.
- velocity_tol
Non-negative relative tolerance around target velocity.
- at_angle
Optional angles in degrees at which torque is interpolated along the rising angular limb.
- gravity
Optional scalar or sample-wise gravity torque in N m to subtract before analysis.
Value
A peak_torque object containing the peak value, time, sample,
angle, angle-specific values, mode, and searched sample indices.
