Abstract [en]

Studies have shown that about a third of all persons over 65 years who live at home fall at least once a year. Development of a lifting device that can help people raise themselves up entirely on their own, or with minimal assistance, would be a revolutionary step for the individual as compared with the lifting devices in use today. A prototype has been developed and the prototype has been tested to verify the approach. Studies have been conducted with nursing staff in a nursing home to find out the conditions for how a walker equipped with a lifting beam could facilitate the work. For caregivers dealing frequently with people who fall, this assistive device can contribute to decreasing occupational injuries.

Abstract [en]

The home should represent safety and security for the person who lives there, and this is an important factor for independence and autonomy in very old age. With aging populations, the needs for long-term care increase, care provided by spouses and/or from the growing home care sector. Injuries among these groups are common.

In this study, an ergonomics perspective was applied in the analysis of some basic daily activities performed by old persons and by home care workers, assisting.

  • The postures and movements of home care staff assisting at toilet visits, and transferring persons from wheelchair to toilet, were measured and analysed.

  • Some daily activities related to making food and washing clothes, performed by a group of persons between the age of 75 and 100, were measured and analysed.

  • The task of getting up from the floor – on your own and with the help of a walker equipped with a lifting device – was analysed with the help of older persons and nursing staff. The design was built on the knowledge gained from analysing how older people get up from floor.

  • Requirements for access with a four-wheeled walker in the local built environment were investigated.

Observations were made with the help of video recording. Postures were recorded with the CUELA measurement system. The VIDAR ergonomics evaluation instrument was used to register the participants’ experiences of discomfort and pain during getting up from the floor with or without the walker with a lifting device. Structured interviews were used to find out about older peoples’ experience of using the four-wheel walker.

It is concluded that ageing at home requires improved architectural and technical bathroom design and improved access in the local built environment.

2. The Adoption of Ergonomic Innovations for Injury Prevention: Examples from the building construction and health care industries

2014 (English)Doctoral thesis, comprehensive summary (Other academic)
Abstract [en]

A good work environment is important for the individual, for industry and for society. The work environment research has, predominantly, targeted identification of problems and the measurement of the size of these problems.

Innovations to reduce the incidence of musculoskeletal disorder, MSD, have been introduced in different branches of industry, but with limited success.

Few of the ergonomic innovations developed for the building and construction industry have reached a sufficient level of adoption. Ergonomic innovations in the health care sector are of an incremental character and seem to have similar problems of adoption as the ones in the building and construction industry.

Three examples of ergonomic innovation are examined in the thesis:

  • a glue spreader for floor layers

  • a four-wheel walker with a lifting device

  • a sonographer’s scanning support device

The studies show that an ergonomic innovation is not adopted for prevention of occupational injury unless the innovation also has other relative advantages apart from the ergonomic ones. For the group who already has sustained an injury, it is enough that the ergonomic problems are solved, while the other, symptom-free group, requires other advantages in order to adopt the innovation; increased production economy seems to be the most prominent potential advantage.
