“…The contralateral downgrading of motorneuron activation may serve as a mechanism to maintain a bilateral balance of motor output. It is common practice to assess the amount of muscle weakness after trauma or surgery using the contralateral side as baseline reference [15,21,22,24]. Well known examples are the Cybex Score and the "one-leg hop" in the evaluation form of the International Knee Documentation Committee in which the functional deficit is given as a percentage of the opposite leg [16,22].…”

Well known examples are the Cybex Score and the "one-leg hop" in the evaluation form of the International Knee Documentation Committee in which the functional deficit is given as a percentage of the opposite leg [16,22]. The reason for this practice is easy to understand since inter-individual variations in muscle forces are high and depend on several variables like training condition, age, gender and body mass.…”

Central activation deficits have been recognised to be partially responsible for quadriceps muscle weakness after knee injuries effecting the injured as well as the uninjured leg. The purpose of this study was to assess the extent of bilateral activation deficits and its effect on functional muscle tests using the uninjured leg as reference. The study included 30 patients with isolated rupture of the anterior cruciate ligament (group 1), 42 patients with rupture of the anterior cruciate ligament and accompanying joint damage (group 2) and 34 healthy volunteers as reference. The maximum isometric knee extension torque and the maximal voluntary muscle activation (VA) were measured bilaterally using a sensitive twitch-interpolation method. The measured and the true functional deficit, adjusted to a physiological VA of the uninjured side, was calculated. Isolated rupture of the anterior cruciate ligament caused a minor VA-deficit and severe knee injuries more severe VA-deficits of the quadriceps muscles of the injured (VA group 1: 83.8 +/- 1.9 %; group 2: 76.9 +/- 1.8 %) and on the uninjured side (VA group 1: 85.9 +/- 1.8 %; group 2: 77.9 +/- 1.8 %) compared to the control group (VA 91 +/- 0.64 %). Due to contralateral VA-deficits the mean underestimation of the isometric muscle-force deficit was 22 % in group 1 and 48% in group 2. Unilateral knee injuries lead to significant VA-deficits of the quadriceps muscles on both the injured and uninjured legs related to the severity of injury. The validity of tests for the assessment of muscle function is questionable when using the uninjured side as reference.

“…We used the visual analog scale for the pain.The evaluated parameters were measured before and after a 5-week treatment phase with 5 intraarticular injections (one injection per week with 20 mg hyaluronic acid). Results: In knees treated with hyaluronic acid the mean peak torque of the knee extensor was 57 26 17.37 Nm after treatment (p < 0.01) at the angular velocities of 608/s and 1808/s. Significant differences (p > 0.01) between treated and untreated knee were found for total work of the extensor and flexor of the knee.…”
