Clinical Conditions

Electromyography has been used to evaluate the performance of the peribuccal musculature in mastication, swallowing and speech, and is an important tool for analysis of physiopathological changes affecting this musculature. Many investigations have been conducted in patients with auditory and speech deficiencies, but none has evaluated the musculature responsible for the speech. This study compared the electromyographic measurements of the superior and inferior fascicles of the orbicularis oris muscle in patients with profound bilateral neurosensorial hearing deficiency (deafness) and healthy volunteers. Electromyographic analysis was performed on recordings from 20 volunteers (mean age of 18.5 years) matched for gender and age. Subjects were assigned to two groups, as follows: a group formed by 10 individuals with profound bilateral neurosensorial hearing deficiency (deaf individuals) and a second group formed by 10 healthy individuals (hearers). Five clinical conditions were evaluated: suction, blowing, lip projection and compression, and production of the syllable "Pa". It was found that the deaf patients presented muscle hyperactivity in all clinical conditions, and that the inferior fascicle of the orbicularis oris muscle showed higher electromyographic activity rates, suggesting the need for a hearing-speech treatment with emphasis on oral motricity.

Abstract Context: Gastrocnemius stretching exercises often are prescribed as part of the treatment program for patients with overuse injuries associated with limited ankle dorsiflexion. However, little is known about how the position of the subtalar joint during gastrocnemius stretching affects ankle dorsiflexion range of motion (ROM). Objective: To determine the effect of subtalar joint position during gastrocnemius stretching on ankle dorsiflexion ROM. Design: This study was a 3-way mixed-model design. The 3 factors were subtalar joint position (supinated, pronated), lower extremity (experimental, control), and time (pretest, posttest). Lower extremity and time were the repeated measures. Setting: University research laboratory. Patients or Other Participants: Thirty-three healthy volunteers (29 women, 4 men). Intervention(s): Participants performed a gastrocnemius stretching exercise 2 times daily for 3 weeks with the subtalar joint of the randomly assigned experimental side (dominant or nondominant) in the randomly assigned position (supination or pronation). The contralateral lower extremity served as the control. Main Outcome Measure(s): Before and after the 3-week gastrocnemius stretching program, we used goniometers to measure ankle dorsiflexion ROM in weight-bearing and non–weight-bearing positions with the subtalar joint positioned in anatomic 0°. Results: Ankle dorsiflexion ROM measured in weight-bearing and non–weight-bearing positions increased after the gastrocnemius stretching program (P  =  .034 and .003, respectively), but the increase in ROM did not differ based on subtalar joint position (P  =  .775 and .831, respectively). Conclusions: Subtalar joint position did not appear to influence gains in ankle dorsiflexion ROM after a gastrocnemius stretching program in healthy volunteers.

0bjective:To estimate intratester and intertester reliability and learning effects during the Star Excursion Balance Tests (SEBTs).Setting:A university athletic training research laboratory.Subjects:Sixteen healthy volunteers with no history of balance disorders or significant lower extremity joint pathology.Measurements:Length of excursion was measured manually for each trial.Results:ICCs for intratester reliability were .78–.96 on day 1 and 32–.96 on day 2. ICCs for intertester reliability were .35–.84 on day 1 and .81–.93 on day 2. Significant learning effects were identified for 4 of the 8 tests.Conclusions:Estimates of intratester and intertester reliability were high, but adequate practice trials should be performed before taking baseline measures.
