How much stronger is the dominant hand compared to the non-dominant hand?

The dominant hand is generally recognized as being stronger than the non-dominant hand due to factors such as muscle development, coordination, and regular use. Research suggests that the dominant hand can be around 10% stronger than the non-dominant hand. This strength difference is attributed to the increased motor skills and the greater use of the dominant hand in daily activities, leading to improved muscle tone and coordination.

Understanding this dynamic is essential in various fields, including occupational therapy and sports, where the strength and dexterity of hands can significantly affect performance and rehabilitation efforts. The 10% strength difference provides a benchmark for assessing physical capabilities and designing appropriate training and rehabilitation exercises.
