Zusammenfassung

Underloading the surgical limb has been described in biomechanical studies across recovery time points following anterior cruciate ligament reconstruction (ACLr). This study aimed to examine the extent to which laboratory findings translate to daily activities. Limb loading was quantified during a sit-to-stand task in laboratory testing and throughout 2 days of daily activity in 15 individuals 114.8 (17.2) days post-ACLr and 15 controls. Vertical force impulse calculated from force platform (laboratory) and pressure insoles (daily) was used to quantify limb loading. Between-limb symmetry was calculated for limb loading and knee strength measures, 2 × 2 GLM repeated measures determined a significant group-by-limb interaction on daily limb loading. Surgical limb daily loading was lower compared to nonsurgical (p

Moticon's Schlussfolgerungen

In this study the authors aimed at investigating loading strategies of the surgical limb after an anterior cruciate ligament reconstruction. Underloading of the surgical limb was monitored using data derived from Moticon sensor insoles and force plates during daily activities. Computed vertical force impulse showed the presence of underloading in daily activities thereby demonstrating the potential of sensor insoles in monitoring rehabilitation.
