A New Dimension in Hearing

An overview of Starkey's new Muse iQ, SoundLens Synergy iQ, and Halo iQ products that utilize the latest advanced signal processing, Acuity Immersion & Immersion Directionality, to focus on aspects of sound and hearing that contribute to the listener's spatial experience. The course will also introduce Starkey's latest 2.4 GHz accessory.

Modifications in lower leg muscle activation when walking barefoot or in minimalist shoes across different age-groups.

Publication date: Available online 28 October 2017
Source:Gait & Posture
Author(s): Simon Franklin, François-Xavier Li, Michael J. Grey
Ageing is associated with a decline in muscle strength and impaired sensory mechanisms which contribute to an increased risk of falls. Walking barefooted has been suggested to promote increased muscle strength and improved proprioceptive sensibility through better activation of foot and ankle musculature. Minimalist footwear has been marketed as a method of reaping the suggested benefits of barefoot walking whilst still providing a protective surface. The aim of this study was to investigate if walking barefoot or in minimalist footwear provokes increased muscle activation compared to walking in conventional footwear. Seventy healthy adults (age range 20-87) volunteered for this study. All participants walked along a 7m walking lane five times in four different footwear conditions (barefoot (BF), minimalist shoes (MSH), their own shoes (SH) and control shoes (CON)). Muscle activity of their tibialis anterior (TA), gastrocnemius medialis (GCM) and peroneus longus (PL) were recorded simultaneously and normalised to the BF condition. MSH are intermediate in terms of ankle kinematics and muscle activation patterns. Walking BF or in MSH results in a decrease in TA activity at initial stance due to a flatter foot at contact in comparison to conventional footwear. Walking BF reduces PL activity at initial stance in the young and middle age but not the old. Walking in supportive footwear appears to reduce the balance modulation role of the GCM in the young and middle age but not the old, possibly as a result of slower walking speed when BF.

Preoperative determination of nerve of origin in patients with vestibular schwannoma.

Preoperative determination of nerve of origin in patients with vestibular schwannoma.

HNO. 2017 Oct 27;:

Authors: Rahne T, Plößl S, Plontke SK, Strauss C

Abstract
BACKGROUND: Vestibular schwannoma (VS) is a benign tumor that develops in the internal auditory canal and the cerebellopontine angle, potentially diminishing hearing or balance. Most VS tumors arise from one of two vestibular branches: the superior or inferior vestibular nerve. Determining the specific nerve of origin could improve patient management in terms of preoperative counseling, treatment selection, and surgical decision-making and planning. The aim of this study was to introduce a novel scoring system that was designed to determine the nerve of origin.
METHODS: The nerve of origin was predicted based on video head impulse assessments of all semicircular channels, together with cervical/ocular vestibular-evoked myogenic potential tests. The acquired data were entered into a scoring system developed to allocate the tumor origin. Finally, the nerve of origin was definitively determined intraoperatively.
RESULTS: The novel scoring system was applied to five consecutive patients undergoing surgical VS treatment. In one case, no determination was possible. In all other cases, the preoperatively predicted tumor origin was the same as the origin determined during surgery.
CONCLUSION: The scoring system predicts the nerve of origin and will be evaluated in a larger prospective cohort study of VS patients in the near future.
