[Isokinetic muscle test of normal people's knees in different postures]
Objective:
To study the influence of different positions in the isokinetic muscle test of knees by CON-TREX Biomechanical Test and Training System, so as to select the suitable conditions for forensic identification of muscle strength test.
Methods:
Fifty-two healthy volunteers joined the isokinetic muscle strength test in unfixed and fixed position, respectively and in two kinds of angular speed (60 degrees/s and 30 degrees/s). The differences of peak torque (PT) and peak torque angle (PTA) between bilateral knee flexor and extensor were statistically analyzed.
Results:
In the unfixed position, under the two speed, there was statistically significant difference in PT between bilateral knee flexor and extensor (P < 0.05); while in the fixed position, under the two speed, there was no statistically significant difference (P > 0.05). In any kind of conditions, the PTA of bilateral knee flexor and extensor did not have statistically significant difference (P > 0.05).
Conclusion:
The position of the subject influences the results of PT. So the position of subject in knees isokinetic muscle test should be regulated.
