Original Title:
Ακρωτηριασμός κάτω άκρου, πρόσθετο μέλος, μετρήσεις και ασυμμετρίες που προκύπτουν από τον ακρωτηριασμό
Translated title:
Lower limb amputation, additional limb, measurements and resulting asymmetries from amputation
Summary:
As we have seen in other studies, various asymmetries are observed in amputated
athletes in the lower extremities. The purpose of this study was to investigate any
asymmetries that have occurred in amputated individuals who after their amputation
engaged in sports having an additional limb, investigating the flexion and extension of
the hip joint in both the healthy and the amputated and their relationship to the flexion
and the torso extension in the isokinetic dynamometer. Six male athletes were evaluated
on an isokinetic dynamometer at 2 different angular velocities (60o / s and 180o / s).
The results of the study showed that the amputated limb lags behind the healthy limb
in strength both in flexion and extension. More specifically, there appeared to be a slight
asymmetry in both force and torque between the two ends of the order of about 13%.
The largest difference observed between the two extremities was at the mean flexural
strength by 13% at an angular velocity of 180o / s and with p = 0.03 with the amputated
limb lagging behind the healthy one. No significant differences were observed in the
proportion of flexors extending the hip except at 180o with the ratio at the amputated
limb being equal to 0.93 and suggesting a deficit in the extensor muscles of the hip.
The results of the research also found that the ratio (ratio) of the muscle groups of the
flexors and the torso extensions after isokinetic evaluation to be correlated mainly with
both the average flexural strength at the remaining end at an angular velocity of 60o / s
with r = 0.886 and p = 0.019 as well as with the bending moment also at the remaining
end with r = 0.886 and p = 0.019. Even a lesser correlation was found both in the mean
flexural strength at the healthy end at angular velocities of 60 ° / s and 180 ° / s with p
= 0.037 but also in extent. The ratio of flexors of the trunk muscles was found to be
equal to 0.51 which indicates small values of the flexors of the torso and the abdominal
muscles. Understanding that a weak muscular torso in these individuals is believed to
interrupt the transfer of energy to the rest of the body and specifically to the lower
extremities resulting in reduced athletic performance, as it is also understood that it is
very important to reduce deficits between the two limbs and to prevent muscle atrophy
as soon as possible by starting a rehabilitation program immediately.
Core stability, balance, and strength should not be overlooked when designing a
training program for crippled athletes.
