Abstract [en]

Background: Many people with multiple sclerosis (MS) have increased postural sway, which is associated with a higher risk of falls. Significantly increased sway has been found in people with slight or no balance impairment. Measuring postural sway is appropriate to perform in clinical settings; however, technical devices can be costly. The Swaymeter is a low-tech cheaper alter-native, considered reliable and valid in both younger and older populations (Sturnieks et al, 2011).

Aims: To investigate the feasibility and validity of the Swaymeter in people with MS.

Methods: Baseline values in a trial were used, with inclusion cri-teria unable to stand in tandem for 30 seconds; 87 persons with MS were tested in outpatient clinical settings, mean age 54 years (SD 11). Fifteen participants (17%) used an assistive walking device indoors and 52 (59%) outdoors. Assessments of sway were done in the bipedal stance for 30 seconds with no shoes, four con-ditions: floor eyes open (EO); floor eyes closed (EC); foam EO; and foam EC. The Swaymeter recorded displacements of the body in the horizontal plane at waist level. The displacement sway area was calculated in millimetres (anterioposterior × mediolateral). Construct validity was investigated through correlations with the Berg balance scale (BBS), the timed up and go (TUG) test, and the sit-to-stand test.

Results: The postural sway displacements were large: floor EO (n=87) mean area 1393 mm (SD 1612); floor EC (n=82) mean area 3041 mm (SD 4447); foam EO (n=83) mean area 4007 mm (SD 3466); foam EC (n=62) mean area 9178 mm (SD 6514). For floor EO and foam EC, there was no significant correlation between the sway area and any of the balance tests. For floor with EC there was a low correlation (r=−0.266, P=0.016) between the sway area and the BBS, but not the other tests. For the condition foam with EO there were significant low–moderate correlation coefficients for the BBS (r=−0.45, P<0.001), the TUG test (r=0.26, P=0.016), and the sit-to-stand test (r=0.33, P=0.003).

Conclusions: The Swaymeter was feasible in a clinical setting, but only 62 (71%) participants could stand on foam with EC for 30 seconds. Construct convergent validity with dynamic balance tests could not be established becausee most correlation coeffi-cients were low and non-significant. Further studies are needed to investigate the properties of the Swaymeter in MS.
