The Validity and Reliability of a New Simple Instrument for the Measurement of First Ray Mobility.

Several methods have been described to quantify the first ray mobility. They all have certain disadvantages (great size, sophistication, or lack of validation). The objective of this work was to study the validity and reliability of a new instrument for the measurement of first ray mobility.

Validity of clinical methods in the detection of leg-length discrepancies.

Introduction: Lower limb-length discrepancy is highly prevalent in the general population. Numerous methods and measurement instruments for its diagnosis appear in the literature, but there has not been an agreement about their validity. The aim of this work is to determine the validity of the Weber-Barstow manoeuvre (WB) of the pelvic measuring device (PMD) and the block method (BM), in comparison with standing anteroposterior telemetry of the lower limbs in subjects with leg-length discrepancy (LLD).

Static Range of Motion of the First Metatarsal in the Sagittal and Frontal Planes.

The first metatarsal and medial cuneiform form an important functional unit in the foot, called "first ray". The first ray normal range of motion (ROM) is difficult to quantify due to the number of joints that are involved. Several methods have previously been proposed.

Ankle sprain as a work-related accident: status of proprioception after 2 weeks.

Purpose: This study aims at verifying whether proprioception is abnormal or not, two weeks after a grade 1 and 2 ankle sprain in the scope of work-related accident.

Methods: A descriptive, observation and transversal study was designed to compare speed, movement and oscilation of centre of pressure in employees of companies signed up to a mutual company. Participants' healthy feet comprised the control group, and feet that had undergone an ankle sprain due to a work-related accident comprised the cases group.

Radiographic Assessment of Lower-Limb Discrepancy.

Background: This study compares different lower-limb length measurements using tests of lower-limb upright full-length radiography and anteroposterior radiography of load-bearing hips.

Methods: Forty-seven consecutive individuals aged 17 to 61 years (mean ± SD, 31.47 ± 11.

Metatarsal pain and plantar hyperkeratosis in the forefeet of female professional flamenco dancers.

Objectives: The objectives of this study were to determine the frequency of metatarsal pain and of hyperkeratosis on the plantar forefoot in female professional flamenco dancers, and to determine whether there is a relationship between the two disorders.

Method: Forty-four female professional flamenco dancers, with a minimum activity of 25 hrs/wk, participated in this cross-sectional study. The presence or absence of metatarsal pain while dancing was recorded, and plantar pressures were measured on a pressure platform, both barefoot and shod with the usual dance shoe.

Morphofunctional study of brachymetatarsia of the fourth metatarsal.

Brachymetatarsia is abnormal anatomical shortness of the metatarsals. We describe a new diagnostic test that enables quantification of the shortening of the fourth metatarsal in brachymetatarsia. The metatarsodigital alterations most frequently related to this deformity are presented.
