07 Rajfur - Evaluation

The study evaluates the effects of carrying one-shoulder handbags on stabilometric parameters, body posture, and pain occurrence in young women. Results indicate significant differences in center of gravity transfer and stabilometric parameters, with a notable correlation between pain complaints and head flexion range. The findings suggest that carrying a bag on one shoulder can lead to back pain and emphasize the importance of education on proper posture and pain prevention.

ABSTRACT
Background: Posture ergonomics is becoming an increasingly discussed issue in the literature. The effect of
daily habits and attitudes, especially overloading ones, is an important topic of currently conducted research.
Performing simple tasks correctly is an important aspect. The following paper deals with the topic of women’s
handbags and the effect of carrying them on various stabilometric parameters.
Aim of the study: This study aimed to check whether the examined women who carry a one-shoulder bag are
affected by posture and the occurrence of pain.
Material and methods: Forty-two women aged 20–25 years were enrolled in the study and were assigned to
two equal comparison groups: group A – ladies carrying a purse on the right arm and group B – ladies carrying
a purse on the left arm. The following tests were performed: evaluation of postural stability, including total
sway path (SP) using a stabilometric platform, the degree of spinal curvature was assessed with a scoliometer,
the degree of pelvic tilt was measured with an electronic inclinometer, and the extent of lateral head flexion
was checked with an electronic goniometer. Back pain intensity was assessed using the VAS scale.
Results: There appeared to be a statistically significant difference in the transfer of the center of gravity to
the right side in group A and to the left side in group B. As for the stabilometric parameters, only the SP [mm]
parameter achieved statistical significance. The highest correlations were observed in group A, between pain
complaints and the range of head flexion to the right (r= –0.62). In both groups, no significant statistical dif-
ferences were found within the groups with and without declared pain (p>0.05). However, in the intergroup
comparison for patients without a bag (p=0.01), with their own bag (p=0.04), and with a 3 kg bag (p=0.02),
there were statistically significant differences.
Conclusions: A bag worn on one shoulder can provoke the occurrence of back pain. The stabilometric results
indicate abnormalities while free-standing. Education about pain prevention and maintaining proper posture
is important.
