Ultrasound imaging evaluation of structural and textural features in asymptomatic achilles tendons in pre-professional dancers: A cross-sectional study.

Objective: To evaluate performance descriptors, sociodemographics variables and tendon echogenicity of asymptomatic Achilles tendons and to compare the echotexture from different classification subgroups.

Design: A prospective, randomized cross-sectional study was carried out.

Setting: laboratory of university.

Does Function Determine the Structure? Changes in Flexor Hallucis Longus Muscle and the Associated Performance Related to Dance Modality: A Cross-Sectional Study.

: Flexor hallucis longus pathology is one of the most common conditions of the ankle and foot in dancers, due to the high demand of dance movements performed in an extreme plantar flexion and dorsiflexion range of motion. The objectives of this study were to determine the bilateral differences between the thickness and cross-sectional area of the flexor hallucis longus muscle in dancers, to establish possible differences between dance modalities, and to analyze whether there is a correlation between ultrasonographic parameters or performance variables and the dance modality. : A sample of 50 (29 classical and 21 contemporary) full-time pre-professional female dancers were included in the study.

Cross-Cultural Adaptation of the Dance Functional Outcome Survey (DFOS) for Spanish Dancers.

A growing number of research papers regarding Spanish-speaking dancers justifies the need for an adapted Spanish version of the Dance Functional Outcome Survey (DFOS). The objective of this study was to cross-culturally adapt and validate the DFOS for Spanish-speaking dancers. A sample of 127 healthy and injured professional and pre-professional dancers were recruited.

Ultrasound imaging features of the Achilles tendon in dancers. Is there a correlation between the imaging and clinical findings? A cross-sectional study.

Objectives: To analyze the prevalence of tendon pathology and performance associated in pre-professional classic dancers with no history of Achilles tendon (AT) pain.

Design: A cross-sectional study was conducted.

Participants: Twenty-nine classic ballet dancers without AT pain (58 tendons) were recruited.

Comparative Effects of One-Shot Electrical Stimulation on Performance of the Flexor Hallucis Longus Muscle in Professional Dancers: Percutaneous Versus Transcutaneous?

Objective: High demand of flexor hallucis longus (FHL) in the positions of extreme flexion of the ankle and toes is required in the dance. The aim was to investigate the effects of single-shot of ultrasound-guided percutaneous neuromodulation (PNM) vs. single-shot of transcutaneous electrical nerve stimulation (TENS) in performance of the FHL muscle in professional dancers.

Immediate effects of ultrasound-guided percutaneous neuromodulation versus physical exercise on performance of the flexor hallucis longus muscle in professional dancers: a randomised clinical trial.

Background: Ultrasound-guided percutaneous neuromodulation (US-guided PNM) is a minimally invasive intervention. This technique consists of the application of percutaneous electrical stimulation (PES) through an acupuncture needle-like electrode that is placed in close proximity to the nerve or motor point of the target muscle under ultrasound guidance.

Objective: To examine the immediate effects of a stretching exercise, an eccentric exercise and US-guided PNM on the performance of the flexor hallucis longus (FHL) muscle in young dancers.
