Palmilha postural e acupuntura sistêmica influencia na postura, equilíbrio corporal e flexibilidade em mulheres? Ensaio clínico randomizado.

Abstract

Insoles are classified in the literature as prefabricated (silicone), customized (orthopedic) and individualized (postural or proprioceptive). Postural insoles have been used to treat biomechanical changes generated in the foot, however, there are few studies in the literature on their interference with posture, balance and flexibility. Another resource from the east that has been used is systemic acupuncture, addressing the analgesic effects on pain and various diseases, however, there is also little approach on these aspects mentioned above. Because of this, the objective of the research was to analyze the influence of intervention: postural insoles and systemic acupuncture on posture, body balance and flexibility in women. The methodology was characterized by a randomized controlled, parallel and factorial clinical trial, comprising 21 female participants, aged between 18 and 30 years. Participants were randomized individually and allocated into three groups: CG - control (n = 6) - use of common insoles; GPP (n = 9) - intervention with postural insoles; GPA (n = 6) - intervention with postural insoles associated with acupuncture. The instruments used for evaluation were biophotogrammetry, baropodometry and flexibility tests (finger to the floor and sitting and reaching test). Data collection was performed in the pre-intervention and 30 days after. The postural insole was made according to the observational and interpretive postural assessment and by a single researcher. The participants were instructed to use it for four uninterrupted

hours for seven days a week. The intervention with systemic acupuncture in the tendon- muscle acupuncture was performed once a week, for four weeks, with a duration of thirty

minutes per treatment. The delta calculation was performed and the data normality was tested with the Shapiro-Wilk test. The data of flexibility and biophotogrammetry were compared with the Kruskal Wallis test, and those of body balance by the Kruskal Wallis test followed by Mann Whitney and the Anova One Way test followed by Bonferroni. The result of the flexibility variable had a significant increase in the comparison of GCxGPP (0.01) and GCxGPA (0.001). In static baropodometry and stabilometry, with eyes open, the mean left pressure significantly decreased (p = 0.008) in the comparison between GCxGPA. The left anterior mass division (DMAE) had a significant increase (p = 0.02) in the comparison between GCxGP. The left posterior mass division (DMPE) had a significant reduction (p = 0.02) in the comparison between GCxGPP. The results for closed eyes had a significant increase for DMAE (p = 0.01) and DMAD (p = 0.03) when comparing GCxGPP. The left (p = 0.03) and right (p = 0.04) DMP had a significant reduction in the comparison between GCxGP. Regarding the photogrammetry data, there is a reduction for the variable frontal angle of the right (p = 0.02) and left (0.01) lower limb between the GCxGPP; the right leg / hindfoot angle had a significant reduction (0.007) for GCXGPP and a reduction for GCXGPA (0.002) and the left side also had a significant reduction (0.001) for GCxGPP and GPA (0.001). The variable vertical alignment of the right head had the greatest difference between the GCxGPP (0.001); the angle of the right knee had the greatest difference (0.03) for GCxGPA; the horizontal alignment of the left head also had a greater difference (0.008) between GCxGPP. Therefore, the interventions were effective in body posture (anterior, posterior, right and left profile), body balance and flexibility, after thirty days with daily use of four hours. However, neither protocol was more effective than the other.
