MeasurementEvaluationMetric

The measurement_evaluation_metric.py module provides the MeasurementEvaluationMetric enum. This enum contains helper functions to quickly evaluate various metrics from a Measurement object, which is useful for analysis and visualization.

Enum Members

• LUMBAR_ANGLE: The bend angle of the lumbar spine.
• TWIST: The twist angle of the spine.
• LATERAL: The lateral flexion of the spine.
• SAGITTAL: The sagittal flexion of the spine.
• LATERAL_APPROX: An approximation of the lateral flexion.
• SAGITTAL_APPROX: An approximation of the sagittal flexion.
• THORACIC_ANGLE: The angle of the thoracic spine.
• ACCELERATION: The acceleration in the forward direction.
• GYRO: The overall movement based on gyroscope data.

Methods

exec(self, measurements)

Takes a list of Measurement objects or an AnnotatedRecording and returns a list of metric values for each measurement.

func(self, m)

Takes a single Measurement object and returns the calculated metric value.

is_angle Property

A boolean property that is True if the metric is an angle, and False otherwise (e.g., for acceleration or gyro).

Usage Example

from flexlib.models.measurement_evaluation_metric import MeasurementEvaluationMetric
from flexlib.models.flex_reader import FlexReader

# Assuming 'your_recording.csv' contains measurement data
recording = FlexReader.parse('your_recording.csv')

# Get the lumbar angle for all measurements
lumbar_angles = MeasurementEvaluationMetric.LUMBAR_ANGLE.exec(recording)

# Get the twist for the first measurement
first_measurement = recording.measurements[0]
twist = MeasurementEvaluationMetric.TWIST.func(first_measurement)

print(f"Lumbar angles: {lumbar_angles[:5]}...")
print(f"Twist of first measurement: {twist}")
