Clinical Correlates of Between-Limb Synchronization of Standing Balance Control and Falls During Inpatient Stroke Rehabilitation
Neurorehabilitation and Neural Repair, 07/16/2012
Mansfield A et al. – Between–limb center of pressure synchronization for standing balance appears to be a uniquely important index of balance control, independent of postural sway and load symmetry during stance.Methods
- The authors conducted a retrospective chart review of 100 individuals with stroke admitted to inpatient rehabilitation.
- Force plate–based measures were obtained while standing on 2 force plates, including postural sway (root mean square of anteroposterior and mediolateral center of pressure [COP]), stance load asymmetry (percentage of body weight borne on the less–loaded limb), and between–limb synchronization (cross–correlation of the COP recordings under each foot).
- Clinical measures obtained were motor impairment (Chedoke–McMaster Stroke Assessment), plantar cutaneous sensation, functional balance (Berg Balance Scale), and falls experienced in rehabilitation.
- Synchronization was significantly related to motor impairment and prospective falls, even when controlling for other force plate–based measures of standing balance control (ie, postural sway and stance load symmetry).
