| OBJECTIVE: To assess knee flexor-extensor muscular strength in
elderly women with no previous history of musculoskeletal disorders on the
lower limbs using an isokinetic dynamometer, in order to obtain data that
could be used as a comparative parameter in the evaluation of elderly
women with knee disorders, thus facilitating a better rehabilitation of
these patients. METHODS: Twenty-six volunteers aged 75 to 83 years were
studied using a Cybex(R) 6000 isokinetic dynamometer. The chosen angular
velocity was 60 degrees /s, and concentric exercise was used for either
flexion or extension. The studied parameters were: peak torque, angleof
peak torque, and flexor-extensor torque rate. RESULTS: There were no
differences between dominant (D) and nondominant (ND) knee peak torque
values. This was true for both flexor (D = 42.46 +/- 9.09 Nm / ND = 40.65
+/- 9.38 Nm) and extensor (D = 76.92 +/- 13.97 Nm / ND = 77.65 +/- 15.21
Nm) movements. The descriptive statistical analysis of the values obtained
for the flexor-extensor peak torque rate and for the angle of occurrence
of peak torque was the same for the dominant and nondominant sides.
CONCLUSIONS: The values of peak torque for the contralateral side canbe
used as a reference during rehabilitation of elderly women with acute
disease of the knee, and the angular velocity of 60 degrees /s is proper
and safe for isokinetic assessment of elderly
people. |
