Motion Sickness Treatment Apparatus and Method

Methods and apparatus are disclosed for treating motion sickness. In a preferred embodiment a method of the invention comprises operating eyewear having shutter lenses to open said shutter lenses at a selected operating frequency ranging from within about 3 Hz to about 50 Hz. The shutter lenses are opened for a short duration at the selected operating frequency wherein the duration is selected to prevent retinal slip. The shutter lenses may be operated at a relatively slow frequency of about 4 Hz when the user is in passive activity such as riding in a boat or car or in limited motion situations in a spacecraft. The shutter lenses may be operated at faster frequencies related to motion of the user's head when the user is active

Functional implications of minor mandibular asymmetry: clinical and digital research on a sample of healthy patients

OBJECTIVE.The aim of the study is to evaluate the influence that the mandibular asymmetry could have towards the other components of the Stomathognatic system and to further related structures from a functional point of view. MATERIALS and METHODS. A sample of 18 young asymmetric patients, in healthy status, was investigated with clinical evaluation and questionnaires and digital devices such as Electromiography, Stabilometry, T-scan and Formetric. Descriptive and quantitative statistical analysis were performed. RESULTS. ASIM electromyography index was significant only in a short percentage of the sample. Hypertonia of temporalis muscle in the same side of mandibular deviation and the cross-activation of the contralateral masseter were present. The data of the stabilometric platform showed that only 33% of patients had a load discrepancy between right and left side. All patients presented similar and limited postural anomalies during the Formetric examination. No significant results emerged from statistics . CONCLUSIONS. From the emerging data, mandibular asymmetry does not seem to be considered a potential risk factor for the development of functional anomalies both in the stomatognatic system and in the postural one. The only issue that should be considered is the condylar retrusion of the mandibular shortest side that is a possible destabilizing factor of the TMJ condyle-disc coordination

A descriptive study of International Special Olympic athletes\u27 vision care needs

Three hundred-seventy International Special Olympics participants and 115 staff members representing 39 countries participated . in a vision screening conducted by 32 members of the \u27 American Optometric Association\u27s Sports . Vision and/or Low Vision Sections during the 1991 International. Special Olympics, held in Minneapolis/St. Paul. The. program also included emergency eyecare services and educational· benefits relating to the role of vision in athletic and life performance. An age-matched population of normal nonathlete students were · compared on several measures of visual sensitivity and visual-motor performance. Results of the program substantiated the findings of the 1984-86 Oregon · State Special Olympics vision care program. An unmet need for comprehensive eyecare exists within the International Special Olympics population. Areas of greatest concern include the large number of competitors\u27 never having received vision care, nearly 113 of\u27 the athletes participate with uncompensated or. residual refractive error, and the increased risk of ocular trauma resulting from lack of · eye protection requirement

Exploring glass as a novel method for hands-free data entry in flexible cystoscopy

We present a way to annotate cystoscopy finding on Google Glass in a reproducible and hands free manner for use by surgeons during operations in the sterile environment inspired by the current practice of hand-drawn sketches. We developed three data entry variants based on speech and head movements. We assessed the feasibility, benefits and drawbacks of the system with 8 surgeons and Foundation Doctors having up to 30 years' cystoscopy experience at a UK hospital in laboratory trials. We report data entry speed and error rate of input modalities and contrast it with the participants' feedback on their perception of usability, acceptance, and suitability for deployment. The results are supportive of new data entry technologies and point out directions for future improvement of eyewear computers. The findings can be generalised to other endoscopic procedures (e.g. OGD/laryngoscopy) and could be included within hospital IT in the future
