- Brief Summary
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.
- Detailed Description
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.

Group Intervention Description Group 1 Original IPAQ followed by a revised one. In the first week, this group will receive a physical activity diary and be required to fill it out for 7 days. After completion of the activity diary, group 1 will receive an original International Physical Activity Questionnaire short form (IPAQ-sf). Group 1 will be asked to fill it out with information about physical activities in the last 7 days. In the second week, the group will need to fill another physical activity diary for 7 days. After the completion of this, group 1 will be asked to fill a revised version of IPAQ-sf to describe physical activities in the last 7 days. Group 2 Revised IPAQ followed by an original one. In the first week, this group will receive a physical activity diary and be required to fill it out for 7 days. After completion of the activity diary, group 2 will receive a revised version of International Physical Activity Questionnaire short form (IPAQ-sf). Group 2 will be asked to fill it out with information about physical activities in the last 7 days. In the second week, the group will need to fill another physical activity diary for 7 days. After the completion of this, group 2 will be asked to fill an original IPAQ-sf to describe physical activities in the last 7 days.
- Primary Outcome Measures
Name Time Method Total physical activity duration 16 days 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.
- Secondary Outcome Measures
Name Time Method Physical activity duration for different intensities from original and revised IPAQ-sf 16 days 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.Qualitative inputs from the pilot study participants for all of the study instruments 16 days 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.
