Cardiac Output II: Effect of Stroke Volume on Cardiac Output

Cardiac Output II: Effect of Stroke Volume on Cardiac Output

Cardiac output (CO), the amount of blood the heart pumps per minute, is a parameter in cardiovascular physiology determined by stroke volume and heart rate. Stroke volume, the amount of blood pushed from one of the ventricles per heartbeat, is influenced by preload, afterload, and contractility.
Preload
Preload refers to the initial elongation of the cardiac myocytes before contraction and is related to the volume of blood filling the heart at the end of diastole, or end-diastolic volume. The...

Summary

Individuals post-stroke have significantly impaired turning capacity, requiring more steps and time. This reduced turning ability is linked to gait asymmetry and functional ambulation levels.

Background:

Stroke survivors often experience impaired mobility, affecting daily activities.
Turning is a critical component of gait and balance, yet it is frequently compromised after stroke.

Purpose of the Study:

To compare turning capacity in ambulatory individuals post-stroke with able-bodied controls.
To investigate the relationship between turning capacity, functional ambulation, motor recovery, and gait asymmetry in stroke survivors.

Main Methods:

A cross-sectional study involving 13 chronic stroke survivors and 10 controls.
Turning capacity was quantified by steps and time for 45-, 90-, and 180-degree turns.
Functional ambulation, balance, and gait asymmetry were assessed using standardized clinical measures.

Main Results:

Stroke survivors required significantly more steps and time to complete turns compared to controls.
Turning capacity, particularly for 180-degree turns, correlated significantly with functional ambulation measures (10-m walk, Timed Up and Go, Emory Functional Ambulation Profile, Berg Balance Scale).
Gait asymmetry was also significantly correlated with 180-degree turning capacity.

Conclusions:

Turning capacity is demonstrably compromised in ambulatory individuals post-stroke.
Impaired turning is associated with increased gait asymmetry and reduced functional ambulation.
Further research is needed to understand the biomechanical and neurological underpinnings of turning deficits in hemiplegic gait.
