The aim of this study was to assess the immediate effect of bilateral talocrural joint manipulation on the postural balance of healthy subjects. Ninety healthy subjects (21 males and 69 females) were included in this study. The mean age, height and body weight of the subjects were 22.21 years, 165.1 cm and 62.58 Kg, respectively. Following collection of anthropometric data, the subjects were allocated randomly into an experimental group (receiving real talocrural joint manipulation), a placebo group and a control group. Before and after manipulation, the subjects performed two postural balance tasks, inquiet standing position (eyes open and eyes closed) on a force platform. The stabilometric data were recorded for 60 seconds in each condition. Sway area, medio-lateral (ML) and anteroposterior (AP) velocities and median frequency were calculated from the center of pressure (COP) displacements. The results showed that in the experimental group the COP sway velocity decreased in both directions of movement (AP and ML) and in both visual tasks (eyes open and eyes closed). In general, the placebo and control groups had similar postural balance across balance parameterss. Significant effect of the bilateral talocrural joint manipulation was found on main balance parameter like COP velocity in the anteroposterior and mediolateral directions. These results have some much implications for manual therapy rehabilitation of individuals with ankle†instability.†
