Function and Gait in Patients with Knee Osteoarthritis before and
after Muscle Rehabilitation. Arch Phys Med Rehabil 73(10):972,
1992.
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.
