PolyU develops simplified Tai Chi exercise for elderly people with impaired vision
Researchers of The Hong Kong Polytechnic University (PolyU)'s Department of Rehabilitation Sciences have developed a novel set of simplified Tai Chi exercise for visually impaired elderly people. They also found the new exercise good for improving their sense of balance control and reducing the risk of fall.
This pioneering study was funded by the S.K. Yee Medical Foundation and jointly conducted by Dr William Tsang and Dr Amy Fu of PolyU's Centre for East-meets-West in Rehabilitation Sciences.
They have simplified the 24-form Yang style Tai Chi into 8-form and offered it to elderly people with visual impairment. Since the participants are learning Tai Chi through tactile guidance given by the master, this set of exercise is thus called "Tactile Tai Chi for the Visually Impaired".
Researchers have enrolled forty older people with visual impairment and divided them into two groups for the study. Among them, 20 Tai Chi participants were asked to practise in 90 minute sessions, three times a week for 16 weeks, while the subjects in the control group joined a percussion activity and learnt to play the Djembe. After four months, it was found that the Tai Chi participants showed significant improvements in their balance control, head and trunk movement when compared to the control group.
The result of this study has been published in the latest issue of international journal Age and Ageing. The findings also correlated with the result of a previous study relevant to Tai Chi, conducted in 2004 by the same Centre, which affirmed that practising Tai Chi could help improving the knee joint position sense.
Dr William Tsang added that the simplified Tai Chi exercise is also fit for visually impaired people of different ages to practise, not just for elderly people. The research team has made some DVDs to introduce the exercise in details.
The University sincerely thanked the S.K. Yee Medical Foundation for its support and the Hong Kong Society for the Blind for facilitating this study.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
