Limb loading measurements serve as an objective evaluation of asymmetrical weight
bearing in the lower limb. Digital weighing scales (DWSs) could be used in
clinical settings for measurement of static limb loading. However, ambiguity
exists whether limb loading measurements of DWSs are comparable with a standard
tool such as MatScan. A cross-sectional study composed of 33 nondisabled
participants was conducted to investigate the reliability, agreement, and
validity of DWSs with MatScan in static standing. Amounts of weight distribution
and plantar pressure on the individual lower limb were measured using two DWSs
(A, B) and MatScan during eyes open (EO) and eyes closed (EC) conditions. The
results showed that intra- and interrater reliability (3, 1) were excellent
(0.94-0.97) within and between DWS A and B. Bland-Altman plot revealed good
agreement between DWS and MatScan in EO and EC conditions. The area under the
receiver operating characteristic curve was significant and identified as 0.68 (p
= 0.01). The measurements obtained with DWSs are valid and in agreement with
MatScan measurements. Hence, DWSs could be used interchangeably with MatScan and
could provide clinicians an objective measurement of limb loading suitable for
clinical settings.
