Petrella M, Gramani-Say K, Serrão PR, Lessi GC, Barela JA, Carvalho RP, Mattiello SM. Measuring postural control during mini-squat posture in men with early knee osteoarthritis. Hum Mov Sci. 2017 Apr;52:108-116.
In this study 24 people (mean age: 52.35±5.00) with knee osteoarthritis grades I and II and 24 people (mean age: 51.40±8.07) without knee osteoarthritis participated in this study. The authors of this study emphasize the importance of rehabilitation with eccentric training from the early degrees of knee osteoarthritis to prevent postural instability and quadriceps muscle strengthening.
