Static Balance Differences Between Young And Middle-aged Adults


Today, scientists are still interested in the components of balance and what keeps a person’s body upright while sitting or standing. Several systems contribute to other functions in the body.

Body Position Theory

As we change positions with our bodies, our center of gravity also changes. A change in posture creates a change in force, and the body’s center of gravity must shift to get back up easily or at all.

Types Of Balance

Dynamic balance is the type associated with reactive movement. Static balance is the type that relates to remaining upright or keeping posture. This is accomplished through somatic sensations and vision controlled by your cerebellum.

A Comparative Study

In one study, the static balance differences between young and middle-aged adults were compared. The participants were screened beforehand to ensure that they had similar levels of activity. None of the participants showed signs of problems with movement of their lower limbs, and they did not have specific diseases affecting this region. The participants were also screened based on similar weights and heights.

Each subject stretched and exercised lightly to analyze and compute the results.

Differences In Balance Between Young And Middle-aged Adults

The results of the study showed that young adults had better balance with eyes opened and with eyes closed when compared to deteriorate.

Another consideration pointed out in this study was whether adults focused on a fixed point when they were standing with their eyes open. Researchers believed that the young and middle-aged adults who focused on a specific point did better on the test than those who did not focus on a fixed point. They recommended using a fixed point for all participants in future research when measuring static balance.


In this instance, an athlete was originally diagnosed with minor quadriceps muscle strain and was treated for four weeks, with unsatisfactory results. When he came to our clinic, the muscle was not healing, and the patients’ muscle tissue had already begun to atrophy.

Upon examination using MSUS, we discovered that he had a full muscle thickness tear that had been overlooked by his previous provider. To mitigate damage and promote healing, surgery should have been performed immediately after the injury occurred. Because of misdiagnosis and inappropriate treatment, the patient now has permanent damage that cannot be corrected.

The most important advantage of Ultrasound over MRI imaging is its ability to zero in on the symptomatic region and obtain imaging, with active participation and feedback from the patient. Using dynamic MSUS, we can see what happens when patients contract their muscles, something that cannot be done with MRI. From a diagnostic perspective, this interaction is invaluable.
