Effect of Integrated Dual-Task Trunk Stabilization and Balance Training in Sedentary Adult Females

Effect of Integrated Dual-Task Trunk Stabilization and Balance Training on Balance, Trunk Muscle Activation, and Visual-Motor Integration Performance in Sedentary Adult Females: A Randomized Controlled Trial

Balance and postural control are fundamental components of functional independence and quality of life in adults. Deficits in trunk stability and balance are strongly associated with increased fall risk, impaired mobility, and decreased ability to perform activities of daily living in sedentary individuals and clinical populations. Trunk muscles play a key role in stabilizing the spine and coordinating movement; their activation is essential for maintaining balance during static and dynamic tasks. Evidence suggests that targeted trunk training can significantly improve postural control and functional outcomes.
