Association between Hand-Eye Coordination and Handgrip Strength in Children Post-Healing of Distal Radius Greenstick Fractures

Purpose: To compare the effects of high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) on postoperative quadriceps strength, cardiorespiratory fitness, and functional recovery in patients undergoing total knee arthroplasty.Methods: In this randomized controlled trial, patients between ages 45-65 after TKA were randomized to 24 weeks of HIIT or CMIT (3xweek) in addition to standard physiotherapy.HIIT was performed with cycling at 85-95% peak power; CMIT at 55-70% HRR.Outcomes were VO2max, quadriceps strength, 6MWT, TUG, OKS, and QOL at baseline, 8 and 24 weeks.Results: High-Intensity Interval Training (HIIT) and Continuous Moderate Intensity Training (CMIT) were compared for effects on knee function, walking endurance, functional performance, quality of life, quadriceps strength, and aerobic capacity (OKS, 6MWT, TUG, WHOQOL-BREF, VO2max, and quadriceps strength).Quadriceps strength and VO2 max were not normally distributed; OKS, 6MWT, TUG, and QOL were normally distributed.Mixed ANOVA showed significant time (p < 0.001) and time x group interactions in favor of HIIT for OKS, 6MWT, and TUG.Quality of life was improved equally in the two groups (p > 0.05).Friedman test revealed significant increases in quadriceps force and VO2max over 24 weeks (ch2=168.00,p < .001).No baseline differences were identified (p = 0.223-1.000),but increases from week 8 onward were significantly greater in response to HIIT (p < 0.001-0.014). Conclusion: High-Intensity Interval Training (HIIT) is more beneficial than Continuous Moderate IntensityTraining (CMIT) in improving knee function, walking endurance, functional performance, quadriceps strength, and cardiorespiratory fitness, and both equally improve quality of life.
