Objective:
To consolidate the evidence on the effect of physical exercise on fear of falling in individuals with stroke.
Data Sources:
PubMed, CINAHL, Cochrane Database and MEDLINE.
Methods:
An extensive database search was conducted to identify the randomised controlled trials that examined the effect of physical exercise on fear of falling post-stroke. Grading of Recommendation, Assessment, Development and Evaluation (GRADE) was used to assess the quality of evidence for each meta-analysis.
Results:
Fourteen trials totalling 1211 participants were included in this review. Thirteen of these (1180 participants) were included in the meta-analyses. In the primary analysis, very low-quality evidence suggested that exercise reduced fear of falling post-stroke (standardized mean difference (SMD) 0.48; 95% confidence interval (CI) 0.23 to 0.72). The effect was diminished at three- to six-month follow-up after exercise training ended (SMD -0.09; 95% CI -0.27 to 0.10; high-quality evidence). In the sensitivity analyses, the treatment effect was more pronounced in individuals with a lower baseline Berg balance score (BBS ≤45; SMD 0.53; 95%CI 0.17 to 0.88) and for those trials with exercise frequency of ≥3 sessions per week (SMD 0.70; 95%CI 0.39 to 1.01). Compared with circuit-based training consisting of a combination of walking, balance and strengthening exercises (SMD 0.27; 95% CI -0.09 to 0.63), walking programmes seemed to generate a larger effect on fear of falling (SMD 1.06; 95%CI 0.43 to 1.70).
Conclusion:
Physical exercise was beneficial for reducing fear of falling in individuals with stroke, particularly those with poorer balance ability.

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...
01:26Exercise Stress Test
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
Purposes

Sustained exercise increases the muscles' oxygen demand, which can be...
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...
