Clinical Characteristics and Bone Mineral Density Score in Post-Stroke Neuromuscular Deficit

Tables

↓  Table 1. Example of Delta BMD Calculation Using Data of Age and Stroke Onset
 
A 55-year-old man with a history of stroke 18 months before examination
BMD: bone mineral density.
Delta BMD of wrists = -0.205 + 0.009 × (onset of hemiparesis in months) + 0.002 × (age in years)
= -0.205 + 0.009 × 18 + 0.002 × 55
= 0.067 adjusted R squared 48.6%
Delta BMD of hip = 0.053 + 0.010 × (onset of hemiparesis in months)
= 0.053 + 0.010 × 18
= 0.233 adjusted R squared 61.4%

 

↓  Table 2. Clinical Characteristics of Subjects
 
Characteristics Mean (SD) P score
BMD: bone mineral density; SD: standard deviation.
Age 54.71 (7.522) 0.011
Hemiparesis onset (months) 17.32 (4.388) 0.63
BMD healthy wrist 0.802 (0.149) 0.328
BMD paretic wrist 0.741 (0.15) 0.595
BMD healthy hip 0.833 (0.15) 0.228
BMD paretic hip 0.770 (0.15) 0.44
BMD spine 1.005 (0.20) < 0.001

 

↓  Table 3. Multivariate Analysis of Hip Delta BMD
 
Predictor variables Parameter estimation 95% confidence interval P value
BMD: bone mineral density.
Constant 0.053 0.004 - 0.102 0.034
Duration after stroke onset 0.010 0.007 - 0.013 < 0.001
Age 0.154
Motoric strength of lower extremities 0.705

 

↓  Table 4. Multivariate Analysis of Wrist Delta BMD
 
Predictor variables Parameter estimation 95% confidence interval P value
BMD: bone mineral density.
Constant -0.205 -0.325 to -0.084 0.002
Duration after stroke onset 0.009 0.005 - 0.012 < 0.001
Age 0.002 0.001 - 0.004 0.047
Motoric strength of lower extremities 0.558
