Gait training with a wearable curara® robot for cerebellar ataxia: a single-arm study

Table 2 Comparison of characteristics of the current study with those of previous studies

	Current study (n = 18)	Miyai et al. (immediate intervention group: n = 21) [6]	Bunn et al. (therapy group: n = 6) [8]
Intervention duration (weeks)	2	4	4
Intervention program	Robot-assisted gait training	Physical/occupational therapy	Home-based balance exercise
Age (years) Mean ± SD	62.8 ± 10.0	63.5 ± 11.0	60.2 ± 10.5
SARA score baseline Mean ± SD	10.6 ± 4.0	12.2 ± 3.2	11.8 ± 6.7
Difference in SARA score after the intervention Mean ± SD	− 0.1 ± 1.7	− 2.8 ± 1.8	− 1.8 ± 1.9
Improvement rate of 10 mWT (%) Mean	19.0	19.6	N/A

The improvement rate was calculated as the difference of values between post-intervention and pre-intervention divided by the value at pre-intervention. Each data in the study Miyai et al. were presented as “mean ± standard error”; thus, we calculated the standard deviation of each data in the study as follows: standard deviation = square root of sample size × standard error
N/A: not available; 10 mWT: 10-m walking time; SARA: Scale for the Assessment and Rating of Ataxia
