Description of intervention(s) / exposure
Water based exercise rehabilitaiton
Participants will attend a water-based group exercise program for one hour, twice per week for eight weeks. Each session will be supervised by a senior clinician physiotherapist, experienced in delivering water-based rehabilitation to patients with multiple co-morbidities, and an experienced pulmonary rehabilitation clinician. The exercise training will be conducted in a 33-35ºC hydrotherapy pool. Exercise will consist of 20-30 minutes of lower limb endurance training (walking, jogging, cycling, kicking dependent on the capability of the individual) in addition to 15 minutes of upper and lower body strength training (using speed, turbulence, various depths, equipment).

Outcomes
Primary outcome [1] 318550 0
Feasability - comprised of participation and acceptability .
The number of participants approached, the number who consent, the number of sessions attended and completion rate (defined as undertaking at least 70% of planned sessions) will be recorded to assess feasibility. The 'water exercise acceptability questionnaire' will be used to assess participants’ acceptability with the water environment and exercise sessions. This questionnaire was developed and published by McNamara et al. Acceptability of the aquatic environment for exercise training by people with chronic obstructive pulmonary disease with physical co morbidities: Additional results from a randomised controlled trial. Physiotherapy 101 (2015) 187–192.

The primary outcomes of feasibility will be reported descriptively as numbers and percentages. Paired t tests or Wilcoxon signed-rank test will be used to evaluate the within group changes in symptoms, HRQoL, functional exercise capacity and strength following the water-based rehabilitation program. Statistical significance will be set at p<0.05.

Summary
Brief summary
Exercise training is recommended for people with interstitial lung disease (ILD), to improve their exercise capacity, symptoms and quality of life. However, our group recently found that people who have ILD that is related to their underlying connective tissue disease showed less improvement in physical function and fatigue compared to other types of ILD. People with connective tissue disease often experience muscle and joint pain and weakness and this may make the standard gym-based approach difficult and painful.

Water-based exercise uses warm water to relieve pain and the water's buoyancy reduces the impact on joints. It has been shown to be effective in people with other chronic lung conditions such as chronic obstructive pulmonary disease and in patients with rheumatoid arthritis. No previous studies have examined the benefits of water-based exercise in people with CTD-ILD. This study will establish whether water-based exercise is viable and beneficial in CTD-ILD and whether it can improve their breathing symptoms and physical function.
