Stair climbers restoring seniors' mobility

A pilot project has helped to give housebound elderly a new lease on life. Kathy Zhang reports from Hong Kong.

In January, nonagenarian Ng Lai-kuen visited her husband's grave for the first time in 15 years. Through all those years, she had been unable to climb the steep hill to the site where her husband is buried, so the trip was a dream come true.

The fulfillment of her dream was made possible by the "stair climber," an operator-assisted device with three wheels at each end of an axle that enables objects to be moved easily on steps.
