The Kinetic Health score for your knee is on a scale that ranges from 0 to 100, where a score of 100 represents the healthiest, or best, score possible.

Your Kinetic Health Score:

Your Kinetic Health score is derived from 5 subscales. Knee-specific complaints of pain and your symptoms are the first two scores presented below. The impact of your knee-specific complaints on your function in daily living, function in sport and recreation and knee-related quality of life are the final three scores. Each one these subscales are scored identical to your Kinetic Health score above where a score of 100 is the best possible score.



Function in Daily Living (ADL):

Function in Sport and Recreation (Sport and Rec):

Knee-Related Quality of Life (QOL):

Self-reported knee complaints and the associated effects on function vary with sex and age. Your results are plotted on the graph below (Red) along with the average values specific to your sex and age-range (Orange). Visually compare your scores against the mean scores of your peers. If your score on any subscale is below the range of scores provided then your Kinetic Health is lower than your age and sex matched peers whereas if your range of scores is higher than your Kinetic Health is higher than your age and sex matched peers. Interventions to improve your Kinetic Health include exercise, strength training, surgery, joint support devices, diet and many other possibilities. We encourage you to print your Kinetic Health scores, re-take this test at a later date and track your scores to see if you can improve your Kinetic Health.
