Hearing Loss Film “Hearing Hope” Captures Personal Strength, Scientific Vision

National nonprofit organization Hearing Health Foundation (HHF) has created a new short film, “Hearing Hope,” to expand awareness of hearing health through the voices of those who benefit from and those who carry out the foundation’s life-changing work.

The third most prevalent chronic physical condition in the U.S., hearing loss can affect anyone—from first-grader Emmy to retired U.S. Army Colonel John—but its reach is often underestimated. “It’s one of the most common sensory deficits in humans,” explains cochlear implant surgeon Dr. Anil Lalwani. “I think we have to go from it being hidden to being visible.”

Both a hearing aid user and cochlear implant recipient, seventh-grader Alex is doing his part to make hearing loss less hidden. Smiling, he says he wants people to know that hearing with his devices makes him happy. John wishes to be an advocate for veterans and all who live with hearing loss and tinnitus.

The film also highlights resilience in response to the challenges associated with hearing conditions. Video participant Renee saw her dream of becoming an astronaut halted at 17 when her hearing loss was detected. Now she helps send people to space as an engineer at NASA.

Sophia describes the “low, low rock bottom” she hit when she was diagnosed with Usher Syndrome, the leading cause of deafblindness. Yet she feels special knowing her disability shapes her and sets her apart.

Jason recounts having no resources for hearing loss in children when his son, Ethan, failed his newborn hearing screening. Today he’s grateful for Ethan’s aptitude for language, made possible through his early hearing loss intervention.

With the support of HHF, more progress is made each year. “I’m glad that the doctors are trying to figure out how fish and birds can restore their hearing,” says Emmy.

For the past 60 years, HHF has funded promising hearing science and in 2011 established the Hearing Restoration Project (HRP), an international consortium dedicated to finding biological cures for hearing loss using fish, bird, and mouse models to replicate the phenomenon of hearing loss reversal in humans.

“If [the HRP] can achieve that goal of hearing restoration...that would be a marvelous thing for hearing loss,” reiterates Dr. Robert Dobie.

Through “Hearing Hope,” HHF would like to share its mission and message of hope to as many individuals as possible and reassure those with hearing loss and their loved ones they are not alone. As an organization that channels all efforts into research and education, HHF would greatly appreciate any assistance or suggestions to increase the visibility of the film.

O 027 - There are common patterns of muscle synergy in cerebral palsy crouch gait

Publication date: Available online 25 July 2018

Source: Gait & Posture

Author(s): M. Shojaeefard, A. Khandan, M. Arab Baniasad, F. Farahmand, S. Baghdadi, A. Vafaei, R. Narimani

Abstract
Background

Muscle synergy is the leading hypothesis on how the central nervous system coordinates limb functions. Cerebral palsy (CP) patients utilize fewer synergies, and are believed to have a simpler neuromuscular control. This study was undertaken to determine whether consistent muscle synergies are recruited during ambulation in cerebral palsy crouch gait and how the muscles contribute to such synergies.

Methods

Ten ambulatory CP patients were recruited. All walked with crouch gait. sEMG data were collected from 14 lower limb muscles during gait analysis. Non-negative matrix factorization method was utilized to extract muscle synergies.

Results and significance

A total of five synergy patterns were extracted. One synergy was shared among all patients, and was more active during swing. Another pattern was observed in seven patients, and was active during stance. These data suggest that CP patients with crouch gait utilize the simplest neuromuscular pattern to ambulate. One synergy is responsible for the swing phase, and one for the stance. This will substantially limit the adaptability of gait to various walking circumstances. The results of this study may help guide gait training programs and maximize the efficiency of ambulation in CP crouch gait.

Age-related changes in arm motion during typical gait

Publication date: Available online 25 July 2018

Source: Gait & Posture

Author(s): Patricia Van de Walle, Pieter Meyns, Kaat Desloovere, Jente De Rijck, Julie Kenis, Evi Verbecque, Tamaya Van Criekinge, Ann Hallemans

Abstract
Background

When toddlers learn to walk, they do so with a typical high guard position of the arms. As gait matures, children develop a reciprocal arm swing. So far, there have been no attempts to describe age-related changes of arm movements during walking after this first rapid development.

Research question

The purpose of this study was to investigate age-related changes in arm movement during typical gait.

Methods

All participants (n = 102) received gait analysis using a full-body marker set (Plug-in Gait). Participants were divided into five age-groups: young children (G1: n = 20; 3.0-5.9y), children (G2: n = 24; 6.0-9.9y), pubertal children (G3: n = 26; 10.0-13.9y), adolescents (G4: n = 16; 14.0-18.9y) and adults (G5: n = 16; 19.0-35.2y). Age-related changes in arm movements were investigated by comparing continuous joint angular waveforms (spm1d) between all groups, as well as by comparing the mean joint angle and range of motion of the different joints between age-groups.

Results

The overall shape of movement patterns was comparable across all age groups. Nevertheless, with advancing age, consistency increased. At the shoulder, G1&2 showed a larger mean extension angle compared to older children and adults. The range of shoulder axial rotation was significantly larger in adults compared to all other age groups. In the youngest groups (G1-G2), an increased mean elbow flexion and mean wrist extension angle was found.

Significance

Determining an exact age of maturation of arm swing remains difficult as parameter specific adult-like values were not reached at the same age but should not be set before the age of ten to fourteen years for any parameter.
