Clinical Trial Summary

This study evaluates whether Remote Ischaemic Preconditioning (RIPC) can improve activity, gait and fatigue in people with Multiple Sclerosis. Half the participants will receive RIPC, the other half will receive a sham treatment.

Description:

Regular physical activity has been shown to improve physical fitness, fatigue, quality of life, and reduce the progression of disability in people with multiple sclerosis (MS). However, people with MS are less physically active than others. This is partly due to poor exercise tolerance and fatigue.

Remote Ischemic preconditioning (RIPC) is the exposure of a limb to brief periods of circulatory occlusion and reperfusion by inflating pressure cuffs around arms or legs to above systolic pressures (mmHg), to protect organs against ischaemic injury. RIPC has been shown to improve exercise performance and delay fatigue in athletes. However, there is little to no research examining the effect of RIPC on walking or exercise performance in MS patients. The aim of this trial is to assess whether RIPC can improve activity, gait and reduce fatigue in people with MS.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change from baseline in speed of walking over a one week period	Change in activity levels will be assessed by measuring the average speed of participants walking during the waking hours over a one week period, using a wearable activity monitor for one week before the intervention and during the final week of the 6 week intervention period.	7 weeks
Primary	Change from baseline in number of steps taken over a one week period	Change in activity levels will be assessed by measuring the average number of steps taken during the waking hours over a one week period, using a wearable activity monitor for one week before the intervention and during the final week of the 6 week intervention period.	7 weeks
Primary	Change from baseline in length of stride over a one week period	Change in activity levels will be assessed by measuring the average length of stride during the waking hours over a one week period, using a wearable activity monitor for one week before the intervention and during the final week of the 6 week intervention period.	7 weeks
Primary	Change from baseline in speed of walking during the 6 minute walk test	Speed of walking during the 6 minute walk test will be assessed using wearable sensors at baseline and after the 6 week intervention period. The 6 minute walk test assesses exercise tolerance by assessing walking over the span of six minute.	6 weeks
Primary	Change from baseline in Modified Fatigue Impact Scale (MFIS) Score	A 21 item self reported fatigue scale which assess the effects of fatigue across three domains, cognitive, physical and psycho-social. Each item is scored from 0-4 (0=no effect of fatigue, 4=large effect of fatigue) yielding a total between 0 - 84.	6 weeks
Primary	Change from baseline in Multiple Sclerosis Walking Scale 12 (MSWS-12) score	A 12 item self reported scale which assesses the impact of MS on a patient's walking ability. Each item is scored from 1-5 (1=no impact, 5=high impact), yielding a total between 1-60 which is transformed to a percentage out of 100.	6 weeks
Primary	Change from baseline in Borgs rating of perceived exertion scale score	Exertion after the 6 minute walk test will be measured at baseline and following the 6 week intervention period using the Borgs rating of perceived exertion scale, a self report measure of perceived exertion ranging from 6-20 (6=no exertion, 20=exhaustion).	6 weeks
