چکیده:
The objective of the present study was to comparatively analyze the clinical status of the lower limbs in healthy subjects and subjects with back pain. Forty three (43) male and female subjects with average age of 36.91± 3.97 were selected as the statistical sample of the study. This population was recognized intelligently by utilizing the Nordic Musculoskeletal Questionnaire (NMQ). Furthermore, the NMQ was used to designate 43 male and female subjects with average age of 37.88 ± 4.12 and similar anthropometric characteristics with the statistical population as the research control sample. In the next phase, tibial torsion and femoral torsion angles were measured using a goniometer. Foot typicality was designated using a foot arch index while intercondylar and intermalleolar distances were measured using a clinical caliper. The results depict that the size of the foot arch is steeper in people with back pains compared to those with flat foot arch (p<0.05). It also indicates that there is no significant correlation between the tibia, femur torsion, knee condition of the healthy subjects and subjects with back pain. Therefore, it is deduced that steep foot arch can be a key component in the generation of back pains.

"Numerous researches indicate that in the closed kinetic chain activities of a healthy person, foot hyperpronation can result in internal rotation of the tibia and femur as well as excessive increase in femoral anteversion (7).
RESULTS After data analysis, there was significant correlation between the levels of frequency of foot typicality in healthy subjects, as well as subjects with back pain malady.
At the same time, there was no significant correlation between frequency rate of knee typicality and level of rotation in healthy subjects and subjects with back pain malady (Table 1).
After data analysis, a statistical correlation was found between foot arch indexes in healthy subjects and subjects with back pain malady (Chart A).
(به تصویر صفحه مراجعه شود) DISCUSSION Research findings depict that there is a significant correlation between foot typicality of healthy subjects and subjects with back pain symptoms.
Salehi and Babaei (2004) stated the statistical correlation between femoral torsion angle, halux valgus, halux limitus, foot typicality, soloeus shortness and the emergence of chronic back pain.
It is worth mentioning that the limited nature of the sample, low statistical efficiency, heterogeneous age range and low efficiency of frequency level of foot typicality and back pain syndromes (with a navicular drop of 10 mm) will affect the results of Brantingham et al.
The results of the present study show that there is no significant correlation between average rotation degree and possibility of emergence of back pain symptoms in healthy subjects and subjects with back pain maladies."
