Brief Summary

This study will be conducted to determine the validity and reliability of Kinovea Software measurement of lumbar extensibility using Modified-Modified Schober Test

Conditions

Lumbar Extensibility

Keywords

Modified-Modified Schober Test; Kinovea Software; Lumbar Extensibility

Outcome Measures

Primary Outcomes (3)

• Validity of Kinovea Software Measurement

  To evaluate criterion validity the trials of Modified-Modified Schober test will be concurrently captured by a video camera. Each video underwent downloading onto a computer, followed by analysis using Kinovea software and correlating the results of Modified-Modified Schober Test with those of the kinovea software.

  1 year

• Intra-rater reliability of Kinovea Software Measurement

  To evaluate Intra-rater reliability, the 1st examiner will analyze the video that will be recorded at the 1st assessment and 1 week later using kinovea and the results will be compared.

  1 year

• Inter-rater reliability of Kinovea Software Measurement

  To evaluate Inter-rater reliability, 1st and 2nd examiner will analyze the video recorded in the 1st assessment using kinovea and the results will be compared.
