Sixty-six-year-old Mdm Hee did not appear a likely candidate for stroke. An active and independent senior, she held a job and did household chores herself. It came as a complete surprise to her when she had a stroke in November 2018.
“I remember it was a Monday. I had my lunch and sat down to watch television. My face began to itch, and I felt like I was floating when I was walking,” she recalled. “I took a bath thinking it would help, but it didn’t. Slowly, I began to feel worse as the day went on. So my family called for an ambulance.”
By the Lunar New Year of 2019, a clot the size of a coin was discovered in her brain. Fearing that it could rupture anytime, Mdm Hee was operated on immediately.
“After the surgery I experieced weakness on my left side and I couldn’t lift my left leg up at all,” she said. Determined to regain her active lifestyle again, Mdm Hee chose to stay in the hospital to complete her rehabilitation. “I want to go back to work,” she said.
Piloting the use of exoskeleton technology in community-based rehabilitation for seniors
To improve the rehabilitation outcomes of seniors with physical disabilities, a new pilot programme is bringing bionic exoskeleton technology into the community. Funded by the Balaji Sadasivan Endowment managed by Temasek Foundation, the Temasek Foundation – Improving Mobility via Exoskeletons (iMOVE) programme is piloted at five different rehabilitation settings:
Benefits of therapy with bionic exoskeleton
An exoskeleton robotic device is a wearable robotic device which is designed to help patients with disabilities or weakness result from a spinal cord injury, stroke or other conditions. Programmed to mimic normal walking patterns, therapists can help their patients to stand upright, walk and turn assisted by the device. Patients can re-learn step patterns and weight shifting, with the aim of regaining as much of their natural gait as possible.
Mr Ong Zhong Li, a physiotherapist at Alexandra Hospital explained how he employs the bionic exoskeleton in a physiotherapy session. “We start them (the patients) off by standing up, and get them to find their midline, to get them balanced. The exoskeleton can provide some assistance. Once the patient is accustomed to the system and the way the exoskeleton walks, we can put them on free legs and get them to walk. And if they are better we can give them resistance, to challenge them to work even harder.”
The exoskeleton improves patient recovery over a shorter period of rehabilitation, making it a more cost- and manpower-efficient therapy treatment. As part of the pilot programme, NUH has brought in two types of exoskeletons to determine their suitability for the local population across different health conditions and rehabilitation settings. Dr Effie Chew, Chief of Rehabilitation Services at Alexandra Hospital and a senior consultant in Rehabilitation Medicine, Department of Neurology, NUH, is leading the study which hopes to recruit 400 patients by September 2020. “With this study, we hope to give patients the best chances of achieving their fullest potential in recovery with the help of the latest in rehabilitation technology. We have had good initial experience with the technology, with better and faster improvement in mobility for some of our patients and hope to see the benefits brought to more patients in the community.”
For those who have been by the side of their loved ones coping with stroke, rehabilitation therapy with exoskeleton has brought some cautious optimism.
