Correlation analysis of NKA activity in ND

	MBRS	Age
PD	r=0.5367, p=0.0293*	NS
ALS	r=0.09759, p=0.3756	NS
Ataxia	r=0.6596, p=0.0071**	NS

Notes: Nonparametric correlation (Spearman’s rho, r) was used to correlate clinical features (movement dysfunction in accordance with MBRS and age) and NKA activity in ND subjects with movement disorders;

^*p≤0.05 indicates significance;

^**p≤0.01 indicates highly significant.

Abbreviations: ND, neurogenerative disorder; PD, Parkinson’s disease; ALS, amyotrophic lateral sclerosis; MBRS, Modified Bradykinesia Rating Scale; NKA, Na⁺/K⁺-ATPase; NS, nonsignificant.
