The project will develop knowledge about physical activity in persons with Charcot-Marie-Tooth (CMT) in Norway. We plan to explore instruments to measure physical activity level for the target-group at the community level. We want to understand which type of activities, activity intensities and how persons with CMT perform habitual physical activity. Subsequently, a physical activity measurement instrument adapted to persons with CMT will be developed. This instrument can be used in a future intervention project to promote physical activity in this group.
Charcot-Marie-Tooth (CMT) is a condition that potentially affects daily life function including physical activity. Currently, there is no specific treatment. To prevent physical deconditioning, physical activity recommended. Furthermore, other studies have found the benefit of being physically active, including people with neuromuscular disorders (NMD). . Apart from the physical activity in a rehabilitation center, physical activity also needs to be maintained at the community level in people's everyday life. To measure physical activity level in the community, we need an instrument that is designed for doing so. A questionnaire can be used to collect information about type of activity, activity duration and intensity. The instruments available so far to measure physical activity at the community level are not specifically adapted to persons with CMT. Therefore, this study will focus on revising the questionnaire based on the inputs from persons with CMT themselves. Furthermore, the revised questionnaire will be compared with the original one in addition to yet another instrument.

Total physical activity duration
Correlations of the total physical activity duration measured using original and revised International Physical Activity Questionnaire short form (IPAQ-sf) with an activity diary (in minutes/week). The original IPAQ-sf has been used in Norwegian context and available in Norwegian language. It has a criterion validity of 0.30 (95% CI 0.23-0.36) against accelerometer count and 0.30-0.46 for correlation with a physical activity diary physical activity level (in MET minutes/week). The content of the revised IPAQ-sf was formulated based on the inputs from experts, including the persons with CMT themselves in our reference group. The revised IPAQ-sf will be compared with the original IPAQ-sf in this pilot project.
Time frame: 16 days
Physical activity duration for different intensities from original and revised IPAQ-sf
Correlations of the physical activity duration at three different intensities: high/vigorous, moderate, and light/walking, measured using original and revised IPAQ-sf with an activity diary (in minutes/week). Both original and revised IPAQ-sf can provide description of physical activity level in three different intensities: high/vigorous, moderate, and light/walking. In the activity diary, the Borg's scale will be used to describe intensity in categories: high, moderate, and light. The Borg's scale has weighted mean validity coefficients 0.57-0.72 for various physiological measurements, including: heart rate, blood lactate, %VO2max, VO2, ventilation, and respiration rate.
Time frame: 16 days
Qualitative inputs from the pilot study participants for all of the study instruments
Inputs and comments from pilot study participants for the original IPAQ-sf, revised IPAQ-sf, and activity diary. In this pilot project, we provided field for comments for each point of question in all three questionnaires: original IPAQ-sf, revised IPAQ-sf, and physical activity diary. These qualitative inputs will be analysed for further development and improvement of the study instruments.
