Summary

The purpose of this study was to compare the effects of two exercise programs, using low velocity (LV) and high velocity (HV) contractions, on outcomes of individuals who have undergone total knee arthroplasty (TKA). The experimental hypothesis was that individuals performing HV exercise, compared to LV, would exhibit superior outcomes.

Conditions

  • Osteoarthritis, Knee

Interventions

BEHAVIORAL

Exercise

Participants attended standardized exercise (ex) sessions twice a week for six weeks for 12 sessions. Group speed differed for concentric contractions, sit to stand ex, walking, curbs, and stairs. The low velocity ex group performed a concentric contraction in two seconds, and high velocity group in one second or less. End range concentric hold, eccentric contraction, repetition (rep) rest and set rest were the same. Open chain ex was performed at 50% of one Repetition Maximum (RM) x 10 reps x one set and then 80% of 1RM x 10 reps x two sets. Curb height and 1RM was assessed at the first, fifth and ninth sessions. Manual stretching, balance ex, sit to stand support, level of aerobic ex, gait training, and functional training were assessed and progressed at any session.
