Walking Ability Is a Major Contributor to Fear of Falling in People with Parkinson's Disease: Implications for Rehabilitation

Table 2

Multiple linear regression with fear of falling (FES(S) scores) as the dependent variable among people with Parkinson’s disease^{a, b}.

Significant independent variables^c	B (95% CI)	β	P-value	Adjusted 𝑅^2
				Stepwise change	Cumulative
Walking difficulties (Walk 12-G)	1.7 (1.2, 2.2)	0.55	<0.001	0.680	0.680
Fatigue (FACIT-F)	0.74 (0.26, 1.2)	0.22	0.003	0.023	0.703
Turning hesitations (item 6, FOGQsa)	11 (2.5, 19.6)	0.15	0.012	0.014	0.717
Need help from others in daily activities	10 (0.96, 19)	0.13	0.030	0.010	0.727
Fluctuations	−7.6 (−15, −0.48)	−0.11	0.037	0.008	0.735

^aFor the regression analysis, scores were adjusted to be in the same direction: higher scores = more problems.
^bIndependent variables in the analysis were fatigue (FACIT-F), age (years), PD-duration (years), pain (NHP), turning hesitations (item 6, FOGQsa: dichotomized, 1 = turning hesitations), fluctuations (1 = yes), dyskinesia (1 = yes), freezing (item 3, FOGQsa: dichotomized, 1 = freezing), falls (1 = yes), near falls (1 = yes), need help from others in daily activities (1 = yes), and walking difficulties (Walk12-G).
^cListed by order of entry into the model (forward method).
B: regression coefficient; CI: confidence interval; β: standardized regression coefficient.
