Bączkowicz D, Majorczyk E, Kręcisz K - Biomed Res Int (2015)

Bottom Line: We observed that values of parameters VMS, P1, and P2 increase in accordance with the age, but H level decreases.The most significant differences were achieved between the youngest and the oldest participants' groups.Moreover, we show that parameters VMS, P1, and P2 positively correlate with age, contrary to negatively associated H parameter.

ABSTRACT
Aging is associated with degenerative changes in articular surfaces leading to quantitative and qualitative impairment of joint motion. Therefore, the aim of this study is to evaluate an age-related quality of the patellofemoral joint (PFJ) motion in the vibroarthrographic (VAG) signal analysis. Two hundred and twenty individuals were enrolled in this study and divided into five groups according to age. The VAG signals were collected during flexion/extension knee motion using an acceleration sensor and described using four parameters (VMS, P1, P2, and H). We observed that values of parameters VMS, P1, and P2 increase in accordance with the age, but H level decreases. The most significant differences were achieved between the youngest and the oldest participants' groups. Moreover, we show that parameters VMS, P1, and P2 positively correlate with age, contrary to negatively associated H parameter. Our results suggest that the impairment of joint motion is a result of age-related osteoarticular degenerative changes.

Mentions: In Figure 1 representative vibroarthrographic signal courses registered for individuals in 3th decade (between the ages of 20 and 29) and 7th decade (60–69 years) of life were shown, and the values of signal parameters achieved for all tested groups were presented in Figure 2. The parameters VMS, P1, and P2 possess the lowest values in vicenarians and the highest in the oldest individuals' group. Additionally, in the subsequence decades of life (from 4th to 7th) statistically significant higher levels of the discussed parameters in comparison to the youngest group were found (Table 2). The statistical analysis did not indicate any differences in patients who are between the ages of 30 and 59 when the parameters VMS and P1 were considered. In those cases in 7th decade of life, moreover, an about 3-fold higher value of the parameters VMS and P1 in comparison to those in 6th decade was observed. On the other hand, for P2 and additionally for H parameter the linear trends (increase and decrease, resp.) were achieved (Figure 2). But, in the decreasing of H level only one statistically significant difference (between vicenarians and sexagenarians) was observed (Table 2).
