As many people find physical therapy boring and frustrating, Taipei Veterans General Hospital has developed an intelligent rehabilitation system that combines therapy with gaming to help patients focus and find a sense of fun during treatment.
The system combines wearable sensor devices, virtual reality and cloud computing, which allows people to do physical therapy at home or in hospital. It was put to use last month after gaining approval.
During the initial deployment phase, the hospital is focusing on people with adhesive capsulitis — a condition also known as frozen shoulder, which is characterized by stiffness and pain in the shoulder joint.
Lee Si-huei (李思慧), an attending physician at the Department of Physical Medicine and Rehabilitation, said the hospital designed a game in which people with frozen shoulders perform movements along with cartoon characters that are displayed onscreen, making the treatment process more fun and easy.
“The patients do not have to remember the movements or how many times [they have to do them]. They only have to turn on the computer and do the movements along with the progam,” she said.
The system can also pick up readings on the user’s physical condition and set a more suitable therapy session for them. The information can also serve as a reference for designing better medical devices.
“Physical therapy could last for a long period, so we tried to add some fun elements, hoping to increase patients’ motivation and make them more focused during the process,” Lee said.
Physical therapy for people with frozen shoulders can take up to seven years and some people find it difficult to visit the hospital regularly, she added.
The hospital’s experiment on two groups of patients with frozen shoulders — two sessions per week for three weeks — showed that those using the intelligent rehabilitation system have seen a marked improvement compared with those using conventional therapy, Lee said
The system gives people more flexibility, as they can easily fit the physical therapy sessions into their daily schedules and do them wherever they want, and return to the hospital after a certain period to adjust their exercise regime based on their progress, Lee said.
As the system works though the Internet, family members of the patients who are often busy or live overseas can also participate in the physical therapy process, she added.
FAST TRACK? Chinese spouses must renounce their Chinese citizenship and pledge allegiance to Taiwan to gain citizenship, some demonstrators said Opponents and supporters of a bill that would allow Chinese spouses to obtain Taiwanese citizenship in four years instead of six staged protests near the Legislative Yuan in Taipei yesterday morning. Those who oppose the bill proposed by the Chinese Nationalist Party (KMT) demanded that Chinese spouses be granted citizenship only after renouncing their Chinese citizenship, passing a citizenship test and pledging allegiance to Taiwan. The demonstrators, who were protesting at a side entrance to the Legislative Yuan on Jinan Road, were mostly members of the Taiwan Association of University Professors and other organizations advocating Taiwanese independence. Supporters of the bill, led
SILENT MAJORITY: Only 1 percent of Chinese rejected all options but war to annex Taiwan, while one-third viewed war as unacceptable, a university study showed Many Chinese are more concerned with developments inside their country than with seeking unification with Taiwan, al-Jazeera reported on Friday. Although China claims Taiwan as its own territory and has vowed to annex it, by force if necessary, 23-year-old Chinese Shao Hongtian was quoted by al-Jazeera as saying that “hostilities are not the way to bring China and Taiwan together.” “I want unification to happen peacefully,” Shao said. Al-Jazeera said it changed Shao’s name to respect his wish for anonymity. If peaceful unification is not possible, Shao said he would prefer “things to remain as they are,” adding that many of his friends feel
Taiwan has “absolute air superiority” over China in its own airspace, Deputy Minister of National Defense Po Horng-huei (柏鴻輝) told a meeting of the legislature’s Foreign Affairs and National Defense Committee on Monday, amid concern over whether Taipei could defend itself against a military incursion by Beijing. Po made the remarks in response to a question from Democratic Progressive Party Legislator Chiu Chih-wei (邱志偉) on whether Taiwan would have partial or complete air superiority if Chinese People’s Liberation Army (PLA) warplanes were to enter Taiwan’s airspace. Po, a retired pilot, said that the Taiwanese military has “absolute air superiority” over PLA
A shipment of basil pesto imported by Costco Wholesale Taiwan from the US in the middle of last month was intercepted at the border after testing positive for excessive pesticide residue, the Food and Drug Administration (FDA) said yesterday. Samples taken from a shipment of the Kirkland Signature brand of basil pesto imported by Costco contained 0.1 milligrams per kilogram of ethylene oxide, exceeding the non-detectable limit. Ethylene oxide is a carcinogenic substance that can be used as a pesticide. The 674kg shipment of basil pesto would either be destroyed or returned to its country of origin, as is the procedure for all
