Presentation Transcript

  1. Reliability, agreement, and validity of digital weighing scale withMatScan in limb load measurement Senthil N. S. Kumar, MSc; Baharudin Omar, PhD; Ohnmar Htwe, MD; Leonard H. Joseph, MsPT; Jagannathan Krishnan, PhD; Ali Jafarzedah Esfehani, MD; Lee L. Min, BScPT (Hons)

  2. Aim • Investigate reliability, agreement, and validity of digital weighing scales (DWSs) with MatScan to measure limb loading asymmetry (LLA). • Relevance • If proven valid and reliable, DWSs could provide practitioners with an objective limb load measurement tool suitable for everyday clinical practice.

  3. Method • Cross-sectional study with 33 nondisabled participants. • Weight distribution and plantar pressure on individual lower limb were measured using two DWSs (A, B) and MatScan during eyes open (EO) and eyes closed (EC) conditions.

  4. Results • Intra- and interrater reliability: • Excellent within and between DWSs A and B. • Bland-Altman plot: • Good agreement between DWS and MatScan in EO and EC conditions. • Area under receiver operating characteristic curve: • Significant.

  5. Conclusion • Measurements obtained with DWSs were valid and agreed with MatScan measurements. • DWSs could be used interchangeably with MatScan and could provide clinicians an objective measurement of limb loading suitable for clinical settings.
