Deans' stroke musings: Relationships Between Affected-Leg Motor Impairment, Postural Asymmetry, and Impaired Body Sway Control After Unilateral Supratentorial Stroke

Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

Abstract

Background. The relationships between motor impairment of the affected leg, postural control asymmetry, and impaired body sway control after stroke are not well understood.
Objective. To examine the relationship between motor impairment of the affected leg and reduced contribution of this leg to body sway control (ie, dynamic control asymmetry [DCA]) and to determine the relationships between impaired body sway control, DCA, and weight-bearing asymmetry (WBA).
Methods. We assessed quiet-standing balance with eyes open in 70 persons with a unilateral supratentorial chronic stroke using 2 force plates. Center-of-pressure (COP) velocity was calculated for both feet together in the anteroposterior (AP) and mediolateral (ML) directions as a measure of body sway control. Bilateral AP COP velocities were used to calculate an index for DCA and weight borne on each side to calculate WBA. Fugl-Meyer assessment of the lower extremity (FMA-LE; range: 0-28) served as a measure of affected-leg motor impairment.
Results. All participants with FMA-LE <24 showed pronounced DCA, but this was also true for 21% of those with FMA ⩾24. Higher DCA values were related to more WBA (r_s = 0.496; P < .001), and less ML sway control (r_s = 0.268; P = .025). AP sway control was not significantly related to either DCA or WBA.
Conclusions. Even clinically well-recovered stroke survivors with (near) maximal FMA-LE scores may show clear postural asymmetry in terms of the relative contribution of the affected leg to body sway control. WBA seems to be an effective compensatory mechanism to optimize the contribution of the less-affected leg to balance, particularly in the AP direction.
