Abstract
The purpose of this study was to compare the tibial controlsystem (TCS) and sliding cuff (SC) lever arms in the strengthparameters peak torque (PT), average work(AW), averagepower (AP), joint angle at peak torque (JA), and fatigueindex (FI). Fifteen healthy subjects, with no history of kneepathology, performed three knee extension/flexionrepetitions using the right leg at a velocity spectrum of 60,180, 240, and 20 repetitions at 300 deg/sec for each leverarm. TCS and SC were randomly presented with 24 hoursbetween conditions. Significance was set at p < 0.05. Pairedt tests showed that the SC produced significantly greater PT,AW, and AP than the TCS during extension across velocities .Also, SC JA occurred significantly later in the range ofmotion across velocities, whereas FI was significantly greaterfor the SC than the TCS at 300 deg/sec. Paired t tests forflexion data indicated that the TCS produced significantlygreater PT than the SC across velocities and greater AP at 60deg/sec. The SC condition resulted in significantly greaterAW and AP at 300 deg/sec only. The SC and TCS conditionsdid not differ for JA and Fl across velocities. It was concludedthat choice of lever arm significantly influenced the strengthparameters examined in this study.
