Does the speed of the treadmill influence the training effect in people learning to walk after stroke? A double-blind

Objective:
To compare the effectiveness of high-speed treadmill training and progressive treadmill training for stroke patients.
Design:
A double-blind, randomized controlled trial.
Setting:
Inpatient rehabilitation hospital.
Participants:
A total of 61 ambulatory stroke patients.
Interventions:
Patients in both groups underwent treadmill training for 30 minutes with conventional intervention. The progressive training group (n = 31) was trained to walk on a treadmill with a stepwise increase of speed over the treatment period. The high-speed training group (n = 30) trained to begin at 1.2-1.3 m/s, which is faster than the mean speed of stroke patients. All participants underwent 20 training sessions for five weeks.
Main Measures:
Timed up-and-go test, 10-m walk test, 6-minute walk test, and both step lengths and cadence.
Results:
There were significant improvements in the results of the timed up-and-go test (-1.96 vs. -5.02 seconds), 10-m walk test (0.30 vs. 0.47 m/s), 6-minute walk test (38.35 vs. 64.40 m), and in the step length of the affected side (0.14 vs. 0.19 m) and the unaffected side (0.10 vs. 0.12 m) in the high-speed training group compared with those in the progressive training group (p < 0.05). Step width was not changed in either group (p > 0.05).
Conclusion:
These results suggest that high-speed training is an effective method for improving the walking ability of stroke patients.

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...

01:19Cardiac Output I:Effect of Heart Rate on Cardiac Output
Cardiac output (CO) refers to the total amount of blood ejected by one of the ventricles in liters per minute (L/min). In a resting adult, CO ranges from 5 to 6 L/min, adjusting according to the body's metabolic requirements.
Effect of Heart Rate on Cardiac Output
Cardiac output adapts to metabolic demands during stress, physical activity, or illness. The autonomic nervous system regulates heart rate via the sinoatrial node. The parasympathetic nervous system decreases heart...
01:20Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
01:27Regulation of Stroke Volume
Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...
