Objectives To review and evaluate in a prospective study the most frequent postural symptoms and examine the effect of treatment with plantars and/or prismatic lenses correction (legs length dismetry, functional and structural scoliosis).

Methods A group of 100 patients with postural symptoms were evaluated and treated in our institution for more than 36 months. Their symptoms were graduated from 0 to 4 and compared before and after a year of treatment. An x-ray film of the rachis from anteroposterior view was obtained. The aim of the corrections was to obtain the nearest horizontal equilibrium for the different plans of the body and equal distribution of weight. Leg length dismetry was corrected according to the position of the femoral heads and searching for the relative inclination degree of both femoral heads and sacred with the horizontal plan. Correction with prismatic lenses was performed in the cases without leg length dismetry, horizontal sacral base, inclination of the head or shoulder plans.

Results Of the 100 patients, 71 were female and reported mean age 33.7 ± 20.2 SD years. The symptoms more commonly found are shown in table below by frequency sequence at first observation. Improvement after completed treatment was obtained for all analysis symptoms with statistical significance except for temporomandibular joint, hip, knee and foot pain.

Conclusion The treatment of different postural symptoms with plantars, prismatic lenses or both together revealed a global improvement in low back and cervical pain, dizziness, astenopia, headache, dorsal pain, unbalance, migraine, vertigo. The different treatments analysed revealed a clinically significant improvement in low back pain (p = 0,001), cervical pain (p = 0,001), headache (p = 0,000), dizziness (p = 0,000), astenopia (p = 0,005), dorsal pain (p = 0,022), unbalance (p = 0,002), vertigo (p = 0,027), migraine (p = 0,05). This statistical significance improvement difference is higher with the follow-up.
