You described something but gave us NO PROTOCOLS on how to recover quiet standing balance. USELESS, YOU'RE FIRED! Your mentors and senior researchers need to get out of stroke and find something more to their abilities.
Recovery of Quiet Standing Balance and Lower Limb Motor Impairment Early Poststroke: How Are They Related?
Abstract
Background
Recovery of quiet standing balance early poststroke has been poorly investigated using repeated measurements.
Objective
To
investigate (1) the time course of steady-state balance in terms of
postural stability and inter-limb symmetry, and (2) longitudinal
associations with lower limb motor recovery in the first 3 months
poststroke.
Methods
Forty-eight
hemiparetic subjects (age: 58.9 ± 16.1 years) were evaluated at weeks
3, 5, 8, and 12 poststroke. Motor impairments concerned the Fugl-Meyer
assessment (FM-LE) and Motricity Index total score (MI-LE) or ankle item
separately (MI-ankle). Postural stability during quiet 2-legged stance
was calculated as the net center-of-pressure area (COPArea) and direction-dependent velocities (COPVel-ML and COPVel-AP).
Dynamic control asymmetry (DCA) and weight-bearing asymmetry (WBA)
estimated inter-limb symmetries in balance control and loading. Linear
mixed models determined (1) time-dependent change and (2) the between- and within-subject associations between motor impairments and postural stability or inter-limb symmetry.
Results
Time-dependent improvements were significant for FM-LE, MI-LE, MI-ankle, COPArea, COPVel-ML, and COPVel-AP, and tended to plateau by week 8. DCA and WBA did not exhibit significant change. Between-subject analyses yielded significant regression coefficients for FM-LE, MI-LE, and MI-ankle scores with COPArea, COPVel-ML, and COPVel-AP up until week 8, and with WBA until week 12. Within-subject regression coefficients of motor recovery with change in COPArea, COPVel-ML, COPVel-AP, DCA, or WBA were generally non-significant.
Conclusions
Postural
stability improved significantly in the first 8 weeks poststroke,
independent of lower limb motor recovery at the most affected side within
subjects. Our findings suggest that subjects preferred to compensate
with their less affected side, making metrics reflecting inter-limb
asymmetries in balance invariant for change early poststroke.
