ISRCTN - ISRCTN11392629: Exercise rehabilitation trial in Huntington's disease

Plain English Summary

Background and study aims
Huntington's disease (HD) is an inherited neurological disease, which over time results in progressive problems with movement, thinking and behaviour, and ultimately difficulties in undertaking the usual activities of daily living. It is known that keeping physically active is important for any person who has a chronic health condition. Additionally, there is a growing interest in the potential that aerobic exercise may have for brain health, particularly for people with degenerative diseases such as HD. Engaging in regular exercise, however, can be difficult for people with HD given the complex and varied problems that they are faced with on a daily basis. This study aims to evaluate the feasibility and benefit of a supported, structured exercise intervention in people with early to mid-stage HD.

Who can participate?
Men and women aged 18 and over diagnosed with HD.

What does the study involve?
People with HD who enrol in the study will be asked to attend two research assessments (focussing on physical fitness, movement, thinking and walking abilities) over a three-month period at their local HD clinics. After the first assessment, they will be randomly allocated to either the exercise intervention group or the control group. In the intervention group, exercise trainers will work with each participant on an individualised exercise programme, either in their home or at a community gym. The intervention will take place three times per week for 12 weeks, and trainers will supervise the participant in just over half of the sessions. The remainder of the sessions will be conducted by the participant independently, or with the support of a carer or family member.

What are the possible benefits and risks of participating?
There may, or may not be, direct benefits to anyone taking part in this study. The study aims to find out whether or not the exercise intervention is safe, feasible and beneficial to people with HD. By taking part, participants will be helping us to answer this question, which may be of benefit to people with HD in the future. The assessments and intervention are unlikely to cause any undue stress. Care and comfort of participants will be ensured at all times. The proposed exercise training is of moderate intensity and has been developed in line with established protocols, and therefore poses minimal risk.

Where is the study run from?
Leiden (Netherlands), Munster (Germany), Cardiff (Wales), Birmingham (England), Oxford (England)

When is the study starting and how long is it expected to run for?
February 2014 to August 2014

Intervention

People with HD who enrol in the study will be asked to attend two research assessments (focussing on physical fitness, movement, thinking and walking abilities) over a three-month period at their local HD clinics or university research facilities. After the first assessment, they will be randomly allocated to either the an aerobic exercise programme group or the control group. If they are assigned to the intervention, professional trainers will work with each participant on an individualised exercise programme, either in their home or at a community gym. The intervention will take place three times per week for 12 weeks, and trainers will supervise the participant in just over half of the sessions. The remainder of the sessions will be conducted by the participant independently, or with support of a carer or family member.

Participants who are assigned to the control group will be instructed to continue as normal for the 13 weeks between assessments, and will be instructed to not begin any new exercise or physical activity routines. Following completion of the second assessment, the participants in the control group will be offered gym membership for 12 weeks, so long as the results from the intervention group do not indicate any potential harm. This will include two visits by a trainer to instruct the participant in an appropriate exercise programme.

Primary outcome measures

Feasibility in terms of adherence, safety and process. Measures will be taken at baseline and 13 weeks. A follow-up telephone call will be made at 26 weeks to conduct the IPAQ and EQ-5D.

Secondary outcome measures

Assess benefit including physical fitness, cognitive ability and motor function. Measures will be taken at baseline and 13 weeks. A follow-up telephone call will be made at 26 weeks to conduct the IPAQ and EQ-5D.
