Patients with knee osteoarthritis (OA) have been shown to have reduced functional capacity (FC), muscle strength (MS), endurance (ME), contraction speed (MCS), and integrated EMG (IEMG), which improved significantly after quantitative progressive exercise rehabilitation (QPER). The effects of these changes on walking have not been quantified. The goal of this study was to quantify the effects of knee OA on gait before and after QPER. Seven women (60.9 +/- 9.4 hr) with knee OA were studied. Bilateral kinetic analysis was performed using a standard link-segment analysis. Data were analyzed with repeated measures ANOVA (p<0.5). Initially, MS, ME, MCS, and IEMG were reduced (50% of normal); however, they increased significantly (55%, 42%, 34%, and 126%, respectively) after two months of QPER. Assessments of function and degree of difficulty and pain (Jette FSI) also improved significantly (10%, 33%, and 13%, respectively). Compared to age-matched able-bodied subjects, walking speed, stride length, hip ROM (stride), knee ROM (swing), and peak knee extensor (early stance) and ankle (push-off) moments were less (11%, 7%, 16%, 5%, 78%, and 35%, respectively). Increases were observed in ankle ROM (stance), peak knee flexor (early stance), knee extensor (push-off/early swing), and hip flexor (early swing) moments (48%, 27%, 59%, and 29%, respectively). There were no significant changes in these values after QPER. Patients with knee OA have significantly reduced muscle function and altered gait. Although muscle function and functional capacity increased with QPER, gait was not altered.
