Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will conduct eccentric weightlifting (dumbbells) with the healthy arm, which involves lowering a dumbbell.
All training will be instructed and monitored by an investigator and/or a trained exercise physiologist.
The training program runs for 8 weeks, participants come in twice a week for approximately one hour per session. Over the course of 8 weeks, the weights will increase as a percentage of the maximum weight the participants can lift at the start of the experiment (10% 1-repetition maximum weight at the start of the 8 weeks, increasing by 10% each training week).
Before the training program, there will be 2 sessions for baseline testing. These sessions will approximately be 1.5 hours each.
Four weeks after the program there will be a post-measurement which will take around 1.5 hours.
All training and assessment will be done in the 'NeuroRehabilitation and Robotics lab' at the ECU in Joondalup, WA.

Efficacy
Statistical methods / analysis
A recent meta-analysis (Manca et al. 2017) demonstrated a 17.7% increase in muscle strength in the untrained arm after eccentric training. The reported effect size is moderate-to-large. Because this is a phase 0 trial, we will only include a small number of participants (n= 15) for each group, which makes 30 participants in total.

Summary
Brief summary
In this study, we investigate the effects of strength training of the non-affected arm on the affected arm after stroke. It has previously been shown that training of one arm can increase the strength in the trained and the untrained arm. We will test the strength in both arms before, during and after the training program. As a secondary outcome measure, we will test sensorimotor performance with the KinArm exoskeleton and test if our program has an effect on activities of daily living with the stroke-impact-scale.
