5 PLMScoRe results and output - Steph-Fulda/PLMScoRe GitHub Wiki

PLMScoRe will generate an almost complete list of descriptive parameters of leg movements during night recording. All parameters will be generated separately for

  • time in bed (TIB)
  • total sleep time (TST)
  • wake
  • N1
  • N2
  • N3
  • REM
  • NREM

Leg movement descriptors will include all combinations of the following categories:

  • Leg movement type: candidate leg movements (CLM), periodic leg movements (PLM), non candidate leg movements (nonCLM)
  • Side: all, left (l), right (r), bilateral (b), monolateral (m)
  • Associated to respiratory events: yes (r), no (nr)
  • Associated to arousals: yes (a)
  • Statistic: number, no./hour, duration (mean, SD, min, max)

The nomenclature will follow the WASM 2016 specifications:

  • Modifiers that pertain to the leg movement itself i.e. monolateral (m) and bilateral (b) are added before the leg movement type. To increase readability, they will be separated from the leg movement type with and underscore (Examples: m_CLM, b_PLM)
  • Modifiers that pertain to associated events or sleep/wake status are generally added after the leg movement type (Examples: CLMr, CLMS, PLMa)
  • In the case of more than one modifier on either side, capital letter modifiers and non-capital letter modifiers are separated by an underscore (Examples: CLMr_a, CLMSnr, m_PLMSa)

Intermovement interval descriptors include

  • Number of short (< 10s), long (> 90 s), or 10-90 s intervals
  • Anti-log of the mean and SD of the log-transformed (base e) IMI (meaning that IMI will be first log-transformed, mean and SD will be computed and these will be back transformed to the linear scale)
  • for all IMI and IMInr (non respiratory event associated CLMS)

Additional descriptors include

  • the new periodicity index (PI and PInr)
  • Respiratory events: number, no./hour, % with CLM (%RLM = percentage of events that have at least one CLM within the interval chosen to identify respiratory event associated CLM)
  • Arousals: number, no./hour
  • Sleep/wake: duration in decimale hours of TIB, TST, Wake, N1, N2, N3, REM, NREM

IMI plots will be shown, if you have chosen screen or pdf as output

  • for CLMS and CLMSnr on a linear and log scale

###Output options

screen

  • Table with main indices and table with main numbers and IMI plots

pdf

  • Table with main indices and IMI plots (will be generated and saved)

csv

  • Table with all descriptive information (will be generated and saved)

In addition, PLMScoRe will also return a PLMScore object in R that can be used to derive further information.
