The Braden Scale is a clinically valuable tool used to predict pressure ulcers. The scale is divided into six subscales; these subscales determine risk factors associated with skin breakdown. Multiple aspects of the patient's condition are examined (sensory perception, wetness, activity, mobility, nutrition, friction and shear), to limit the patient's susceptibility to skin breakdown. Because pressure ulcers represent a financial burden and a cause of patient discomfort and possible infection, predicting and assessing risk has enormous benefits and significance. This study was conducted to determine the validity of the mobility subscale of the Braden Scale. The mobility subscale is defined as the patient's ability to change and control body positions. The research was conducted in a veteran hospital and participants ranged in age from 45 to 95 years. The tools used were the Braden scale and actigraphy which measures movement. It was placed on the patient's nondominant ankle to observe the patient's larger movements. The researcher defined each score in relation to movement. They hypothesized that increased movement would cause an increase in the mobility subscale score. As expected, mobility subscale scores increased as movement increased. A similar study to predict the risk of ulcers in pediatric patients was conducted to test the validity of using the Braden Q scale. To use a shorter comparable instrument, a modified version of the Braden scale was used, containing only three subscales. The Braden Q scale is a revision of the Braden scale applicable in pediatrics. The two tools used were: the Braden Q scale and the skin assessments. The study sample consisted of 322 patients who remained in bed for at least 24 hours. Patients were observed three times a week, for two weeks, and then weekly until discharge, for a total of 887 individual assessments. It was determined that both the Braden Q scale and the modified Braden scale were adequate tools for measuring skin degradation. Both studies modified the original Braden scale to test the validity of their modifications. The first study relied solely on the Braden Scale mobility scale, while the second study used three of the original subscales to demonstrate comparable results with the overall scale. Both studies were designed to simplify the Braden scale in order to determine the effectiveness of the subscales alone.
