Compare a measured joint ROM to the reference (and the other side)

Compares a measured joint range of motion against the packaged reference angle (see romReference()) and, when supplied, the contralateral (usually unaffected) side - the two comparisons clinicians read a goniometry measurement against.

Usage

romNormalcy(measured, joint, motion, contralateral = NULL)

Arguments

measured

Measured range of motion, in degrees.

joint, motion

The joint and motion (case insensitive); must identify a single reference row.

contralateral

Optional measured ROM of the other side, in degrees.

Value

A one-row data.frame (class "rom_normalcy") with reference_deg, percent_of_normal (NA for an extension-to-neutral motion whose reference is 0 deg), deficit_vs_reference (reference minus measured) and limited (measured below reference); plus contralateral_deg, deficit_vs_contralateral and percent_of_contralateral when a contralateral value is given.

Examples

romNormalcy(100, "knee", "flexion")
#> knee flexion (sagittal): 100 deg vs reference 135 deg (74% of normal, deficit 35 deg)  [AAOS/Norkin-White]
romNormalcy(100, "knee", "flexion", contralateral = 130)
#> knee flexion (sagittal): 100 deg vs reference 135 deg (74% of normal, deficit 35 deg); contralateral 130 deg (deficit 30 deg)  [AAOS/Norkin-White]
