Movement Analysis Profile (GVS per variable plus the GPS)

The Movement Analysis Profile (Baker et al. 2009) collects the per-variable Gait Variable Scores together with the overall Gait Profile Score.

Usage

movementAnalysisProfile(kinematics, norm = NULL)

Arguments

kinematics

Subject kinematics: a numeric matrix with one row per kinematic variable (row names matching norm$variables) and one column per gait-cycle point, or a named list of per-variable curves. Curves are time-normalised to the norm's cycle length via normalizeMovement().

norm

A gait_norm normative reference (from PhysioGaitNorm::loadGaitNorm()); if NULL, the default reference is loaded from PhysioGaitNorm.

Value

A movement_analysis_profile object: a list with gvs (named numeric vector), gps (numeric), variables, and cycle_length.

Examples

norm <- list(variables = c("a", "b"),
             mean = matrix(0, 2, 51, dimnames = list(c("a", "b"), NULL)),
             cycle_length = 51)
movementAnalysisProfile(matrix(1, 2, 51, dimnames = list(c("a", "b"), NULL)),
                        norm)
#> <movement_analysis_profile>
#>   GPS (overall): 1.00 deg
#>   GVS per variable (deg):
#>     a                    1.00
#>     b                    1.00
