Research review (peer-reviewed)abstract
- The overall aim was to gain insight into and understand how physicians and nurses view the implementation of empowerment group education (EGE) in diabetes. Prior to the study the physicians and nurses attended a 2-day empowerment workshop. Further, they had implemented the empowerment approach in two groups of patients with type II diabetes. Three to 9 months later they (five physicians and 11 nurses from six family practices) participated in focus group interviews to evaluate the implementation of the EGE. The interviews were audio-taped, transcribed and analysed using the constant comparative method. The main result showed a conflict in roles. The physicians and nurses knew their role in the traditional approach but not with respect to the empowerment approach, which they needed to grow into. At the same time as they started a new way of working, their role had changed from being an expert to being a facilitator. As experts they felt secure, as facilitators they needed support in their educational process. To implement EGE they required support both from the family practice and from a supervisor in direct connection with the EGE. © 2004 Elsevier Ireland Ltd. All rights reserved.

3D passive walkers : Finding periodic gaits in the presence of discontinuities
- 2001

In: Nonlinear dynamics. - 0924-090X .- 1573-269X. ; 24:2, s. 205-229

Journal article (peer-reviewed)abstract
- This paper studies repetitive gaits found in a 3D passive walking mechanism descending an inclined plane. By using direct numerical integration and implementing a semi-analytical scheme for stability analysis and root finding, we follow the corresponding limit cycles under parameter variations. The 3D walking model, which is fully described in the paper, contains both force discontinuities and impact-like instantaneous changes of state variables. As a result, the standard use of the variational equations is suitably modified. The problem of finding initial conditions for the 3D walker is solved by starting in an almost planar configuration, making it possible to use parameters and initial conditions found for planar walkers. The walker is gradually transformed into a 3D walker having dynamics in all spatial directions. We present such a parameter variation showing the stability and the amplitude of the hip sway motion. We also show the dependence of gait cycle measurements, such as stride time, stride length, average velocity, and power consumption, on the plane inclination. The paper concludes with a discussion of some ideas on how to extend the present 3D walker using the tools derived in this paper.

Arthroscopic findings in wrists with severe post-traumatic pain despite normal standard radiographs
- 2004
-
In: Journal of Hand Surgery - British and European Volume. - : SAGE Publications. - 0266-7681 .- 1532-2211. ; 29 B:3, s. 208-213
-
Journal article (peer-reviewed)abstract
- This study assessed the role of diagnostic arthroscopy following a wrist injury in patients with normal standard radiographs, an unclear clinical diagnosis and persistent severe pain at 4 to 12 weeks. Forty-three patients were included after conservative management had failed to improve their wrist pain so that a stability test could be performed satisfactorily and underwent arthroscopy within 12 weeks. Arthroscopy revealed recent pathology in 41 wrists, of which 17 had significant ligament lesions that might have benefited from acute repair. We conclude that patients with marked persistent post-traumatic symptoms despite conservative management are likely to have sustained ligament injuries despite normal radiographs. We therefore recommend that under these circumstances an arthroscopy is carried out within 4 weeks if the patient and surgeon wish to acutely repair significant ligament injuries.

Repetitive gait of passive bipedal mechanisms in a three-dimensional environment
- 2001
-
In: Journal of Biomechanical Engineering. - : ASME International. - 0148-0731 .- 1528-8951. ; 123:1, s. 40-46
-
Journal article (peer-reviewed)abstract
- The inherent dynamics of bipedal, kneed mechanisms are studied with emphasis on the existence and stability of repetitive gait in a three-dimensional environment, in the absence of external, active control. The investigation is motivated by observations that sustained anthropomorphic locomotion is largely a consequence of geometric and inertial properties of the mechanism. While the modeling excludes active control, the energy dissipated in ground and knee collisions is continuously re-injected by considering gait down slight inclines. The paper describes the dependence of the resulting passive gait in vertically constrained and unconstrained mechanisms on model parameters, such as ground compliance and ground slope. We also show the possibility of achieving statically unstable gait with appropriate parameter choices.

Patient expectations of obesity treatment-the experience from a day-care unit.

Journal article (peer-reviewed)abstract
- BACKGROUND: Unrealistic patient weight loss expectations in treatment of obesity may hamper the modest success which can actually be achieved.SETTING: Academic Obesity Unit Day Care Centre.OBJECTIVE: Description of weight loss expectations and weight loss concerns by questionnaire analyses.RESULTS: Patients were severely obese, with a median initial body mass index (BMI) of 40.7 kg/m(2). Weight loss expectations were generally unrealistic, with women hoping for a loss up to 42%, and men for 29% of their baseline weight (P<0.001). No effects of age on actual weight loss or weight loss expectations were observed.CONCLUSION: Gender differences in weight loss expectations may be important to acknowledge in future development of obesity treatment programmes. Realistic treatment outcome should be described early in a programme to facilitate compliance.

Virtual engineering : an integrated approach to agile manufacturing machinery design and control
- 2003
-
In: Mechatronics (Oxford). - : BioMed Central Ltd.. - 0957-4158 .- 1873-4006. ; 13:10, s. 1105-1121

Journal article (peer-reviewed)abstract
- A virtual manufacturing approach for designing, programming, testing, verifying and deploying control systems for agile modular manufacturing machinery are proposed in this paper. It introduces the concepts, operations, mechanisms and implementation techniques for integrating simulation environments and distributed control system environments so that the control logic programs that have been programmed and verified in the virtual environment can be seamlessly transferred to the distributed control system environment for controlling the real devices. The approach looks to exploit simulation in a much wider range of applications with great advantages in the design and development of manufacturing machine systems. In particular, it facilitates the verification of the runtime support applications using the simulation model before they are applied to the real system. Mechanisms that allow runtime data to be collected during operation of the real machinery to calibrate the simulation models are also proposed. The system implemented delivers a powerful set of software tools for realising agile modular manufacturing systems.
