Purpose: To evaluate the influence of two different heel heights on static balance and on limits of stability during functional reach test, with both the eyes open and eyes closed, in young women (age 22–27) who did not wear heeled shoes habitually. Methods: Thirtyone young women (age 22–27) performed balance tests on a stabilometric platform without footwear and in shoes with 4 cm and 10 cm heels. The center of pressure (COP) deviations range and velocity in anteroposterior (AP) and mediolateral (ML) directions were assessed. The limits of stability were measured when the subject leaned the body in sagittal plane. Results: The ranges of COP deviations in AP and ML directions were already significantly higher in 4 cm heels in comparison to the barefoot condition. COP deviation velocity significantly raised with increasing heel height as well as when the eyes were closed. Conclusions: A more pronounced increase of COP deviation velocity than COP deviation range when measurement conditions become more difficult may indicate that young women anticipate postural corrections by stimulation of ankle proprioception when heeled shoes are worn. High-heeled shoes may lead to alterations in velocity feedback balance mechanism, which may increase the risk of musculoskeletal injuries. Observed in our study adverse effect of heeled footwear on balance may predispose women to falls and injuries. Permanent use of stiletto high heels should be avoided by women.

High heel footwear may be destructive for the spine because of an increased erector spinae muscle bioelectrical activity and increased ground reaction forces affecting lower limbs and the spine. The aim of this study was to evaluate the changes of bioelectrical activity in cervical paraspinal muscle during gait in low and in high heel shoes in different age groups. In 31 women aged 20-25 years and in 15 women aged 45-55 years without neck pain, the bioelectrical activity of the cervical paraspinal muscle was assessed during gait on flat surface with natural speed in three conditions: without shoes, in low (4 cm) and in high (10 cm) heel shoes. Higher bioelectrical activity cervical paraspinal muscle was noted during gait in high heel shoes in comparison to gait without shoes. The changes were more pronounced in the group of subjects aged 45-55 years. The prolonged wearing of shoes with stiletto type heels by individuals without neck pain is not safe for their spine and may lead to chronic paraspinal muscle fatigue.

Mięśnie w obrębie kompleksu lędźwiowo-miedniczno-biodrowego pełnią rolę podtrzymującą dla narządów miednicy mniejszej, odpowiadają za kontyngencję pęcherza oraz pełnią funkcję mięśni oddechowych. Mięśnie dna miednicy są również uważane za ważną część mechanizmu stabilizacji głębokiej kręgosłupa. U pacjentów z zaburzeniami funkcji mięśni dna miednicy mamy do czynienia z dolegliwościami bólowymi w obrębie kręgo-słupa lędźwiowego i miednicy, z objawami nietrzymania moczu oraz z zaburzeniami toru oddychania. Celem pracy jest przedstawienie metodyki zastosowania obrazowania ultrasonograficznego w ocenie funkcji mięśni dna miednicy. Ultrasonografia staje się coraz bardziej popularna w pracy fizjoterapeutów, zarówno w diagnostyce zaburzeń mięśni głębokich kompleksu lędźwiowo-miednicznego jak i jako narzędzie służące do biofeedbacku podczas terapii.

The muscles of the lumbopelvic region play a significant role in musculoskeletal function as well as continence and respiration. The pelvic floor muscles also provide trunk stability. In patients with failure of pelvic floor muscles function we observe low back pain, incontinence and breathing disorders. The aim of this study was to present the methodology of ultrasound evaluation of pelvic floor muscles. Ultrasonography becomes popular in physiotherapy practice both in evaluation of lumbopelvic complex dysfunction and as a biofeedback tool during the therapy.
