The reliability of postural control method in athletes with and without ACL reconstruction: a transitional task

Abstract

[Purpose] To evaluate the intra- and inter-session reliability of dynamic postural control in ACL reconstruction and matched control athletes. [Subjects and Methods] By using force plate, the postural controls of both groups (20 ACLR and 20 healthy matched controls) were assessed during the transitional task from DLS to SLS. The outcome variables included COP displacement and area and the mean velocity of COP. [Results] The balance measures had moderate to high correlation for area (ICC=0.64–0.73) and rang of fore-aft (Rfa) (ICC=0.66–0.80) in the ACLR group and Rfa (ICC=0.70–0.86) in the healthy group. High to very high reliability was seen for rang of sideway (Rsw) (ICC=0.76–0.96) and mean velocity (Mv) (ICC=0.81–0.98) in ACLR and area (ICC=0.70–0.98) and Rsw (ICC=0.84–0.98) and Mv (ICC=0.89–0.97) in the healthy group. [Conclusion] Force plate measures of postural control demonstrated moderate to very high reliability in athletes with and without ACLR during the transitional task. The results of the recent study showed that the assessment of transitional task postural control in athletes with ACLR may reliably be incorporated in the evaluation of the physical function.

Kinetic measurement system use in individuals following anterior cruciate ligament reconstruction: a scoping review of methodological approaches

“…Center of pressure (CoP) velocity was the most commonly measured parameter ( n = 10 [43.4%]) [1, 21, 22, 26, 45, 51, 55, 59, 123, 187]. CoP displacement in anterior‐posterior and medio‐lateral directions [1, 14, 22, 23, 51, 123], and CoP length of path [14, 67, 87, 136, 165, 166] were the second most frequently used parameters, where each was measured in 6/23 (26.1%) studies. The CoP sway area was measured in 5/23 (21.7%) studies [1, 45, 51, 59, 136].…”

“…Finally, balance testing protocols were heterogeneous in terms of testing conditions (single−/double‐leg stance, focusing on a target or not, eyes open/closed, single/dual tasks). Standing balance was assessed under both single‐ and double‐leg stance in 5 (21.7%) studies [22, 23, 46, 47, 51] and in double‐leg stance in 3 (13.0%) studies [1, 136, 165]. The remaining 15 (65.2%) studies assessed single‐leg standing balance only [14, 21, 26, 45, 55, 56, 59, 64–67, 87, 123, 166, 187].…”

“…The remaining 15 (65.2%) studies assessed single‐leg standing balance only [14, 21, 26, 45, 55, 56, 59, 64–67, 87, 123, 166, 187]. Participants were asked to look at a target in 7 (30.4%) studies [1, 51, 56, 64, 67, 123, 166]. In 6 (26.1%) studies, balance was tested in eyes open and closed conditions [14, 26, 66, 123, 136, 187], while 5 (21.7%) studies assessed balance under eyes closed conditions only [22, 23, 45, 55, 59, 165], and the remaining 11 (47.8%) studies had the participants’ eyes open.…”

Most studies (22/23 (95.6%)) assessed balance using a single task [1, 14, 21–23, 26, 45–47, 51, 55, 56, 59, 64–67, 87, 123, 136, 165, 166, 187]; only 1 study used dual tasks (a concurrent physical and cognitive task) [1].
