BMC Neurology

Table 2 Model I (replication[1]): multiple linear regression with fear of falling (FES(S) scores) as the dependent variable in people with Parkinson’s disease, n = 104 ^a

					Adjusted R²
Significant independent variables^b	B (95% CI)		β	P-value	Stepwise change	Cumulative
Walking difficulties (Walk-12G)	−1.844	(−2.423, −1.266)	−0.524	0.000	0.595	0.595
Need help from others in daily activities (PADLS)	−24.960	(−40.672, −9.247)	−0.213	0.002	0.042	0.637
Fatigue (FACIT-F)	0.667	(0.165, 1.169)	0.214	0.010	0.021	0.658

^aIndependent variables in the analysis were: need help from others in daily activities (PADLS: dichotomized, 1 = yes), walking difficulties (Walk-12G), fatigue (FACIT-F), age (years), PD-duration (years), falls (1 = yes), near falls (1 = yes), dyskinesia (dichotomized, 1 = yes), freezing (FOGQsa item 3: dichotomized, 1 = freezing), turning hesitations (FOGQsa item 6: dichotomized, 1 = turning hesitations), pain (dichotomized, 1 = yes).
^bListed by order of entry into the model (forward method).
FACIT-F, the Functional Assessment of Chronic Illness Therapy-Fatigue scale (0–52; higher = better); FES(S), Falls Efficacy Scale (0–130; higher = better); FOGQsa, Freezing of Gait Questionnaire, self-administered version (items are scored 0–4; higher = worse); PADLS, The Parkinson’s disease Activities of Daily Living Scale (1–5; higher = worse; those scoring >2 were categorized as needing help from others in daily activities) Walk-12G, 12-item generic walking scale (0–42; higher = worse).
B: regression coefficient; CI: confidence interval; β: standardized regression coefficient.
