Key Findings
- 01Individuals with multiple sclerosis achieved similar peak oxygen uptake (V̇O₂max) on both the recumbent stepper and the treadmill.
- 02Control participants achieved higher V̇O₂max on the treadmill compared to the recumbent stepper.
- 03Individuals with multiple sclerosis more consistently met criteria for maximal testing when using the recumbent stepper.
- 04The recumbent stepper appears to be a more suitable device for assessing cardiopulmonary function in individuals with mobility limitations.

How to apply
When designing or selecting equipment for fitness assessments, rehabilitation, or exercise programs for individuals with mobility challenges, consider the biomechanical demands and user interface of different machine types.
Project actions
- 01Consider the physical capabilities of your target user group when selecting or designing equipment.
- 02Test prototypes with users who have diverse physical abilities to identify potential barriers.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Randomized crossover design allows for within-subject comparisons, reducing inter-individual variability.
- +Inclusion of both a patient group and a control group provides a comparative perspective.
Limitations
The specific characteristics of the multiple sclerosis patients (e.g., severity of disability) might influence the results, and the control group may not perfectly represent a 'typical' healthy individual.
Reliability & validity
The crossover design enhances internal validity by controlling for individual differences. Reliability would depend on the consistency of the CPET protocol and measurement equipment.
Think critically
How might the design of other common exercise machines (e.g., rowing machines, elliptical trainers) similarly impact individuals with different types of physical disabilities?
Design Principles
"Adaptive design: Exercise and assessment tools should be adaptable to accommodate a wide range of physical capabilities."
This research highlights how the physical interface and biomechanical demands of exercise equipment can create barriers for specific user groups. Designers must consider the functional capabilities and limitations of diverse users when developing tools for assessment or rehabilitation.
What This Means for Your Design
Some exercise machines are better than others for people who have trouble moving. A stepper machine that you sit on works better for testing the heart and lungs of people with multiple sclerosis than a treadmill.

Paragraph starter
The selection of appropriate testing equipment is critical for accurate physiological assessment, particularly for individuals with mobility impairments. Research indicates that devices like recumbent steppers, which reduce reliance on lower-body function, can yield more reliable cardiopulmonary exercise testing results for populations such as those with multiple sclerosis compared to body-weight supported treadmills, which may exacerbate limitations and lead to suboptimal data.
