The intervention group will receive 8 weeks of Progressive Resistance Training (PRT), twice a week, in addition to usual care. An upper limb functional goal will be identified through discussion with the researcher and the participant. PRT will be individually tailored to target two muscle groups and will be chosen in order to develop strength to progress towards the participants functional goal.

The chronic spinal cord injury exercise guideline parameters will be applied (3 sets of 8-10 repetitions, 1-2 mins rest between sets). Participants will be inducted to their PRT programme and will then independently complete the 8 week programme. During each of the following sessions, assistance for set up of equipment and/or limb position will be given by the researcher and/or the participants family, friend or carer, once they have been trained. PRT sessions will be recorded in a diary to monitor sets and repetitions completed, and intensity (visual analogue scale (VAS)).

Participants will continue with their usual care, consistent with standard National Health Service (NHS) care in this population. Usual physiotherapy care is provided, up to 2 times per day, 4 to 5 days per week, each lasting up to 90 minutes. Physiotherapists provide a combination of group exercise and one to one function-orientated physiotherapy sessions to improve balance, general muscle strength, wheelchair and/or transfer skills.

Progressive resistance training programme for individuals following spinal cord injury.

Muscular strength will be quantified using handheld dynamometry, the main upper limb muscle groups will be assessed, bilaterally. Shoulder flexors, extensors, abductors, adductors, lateral rotators, and medial rotators, elbow flexors and extensors, forearm pronators and supinators, and wrist flexors and extensors will be assessed. The order of testing the muscle groups will be consistent.

Handheld dynamometry will be conducted implementing the 'make' test. The participant will exert a maximal force against the device whilst the assessor will maintain the position of the device. Three trials will be performed for each upper limb muscle group. Prevention of muscle fatigue will be achieved by a 30-second recovery after each trial and 2 minutes rest between muscle groups. One or 2 trials will be used to familiarise participants with the testing procedure.

Muscular strength will be quantified using manual muscle testing, the main upper limb muscle groups will be assessed, bilaterally. Shoulder flexors, extensors, abductors, adductors, lateral rotators, and medial rotators, elbow flexors and extensors, forearm pronators and supinators, and wrist flexors and extensors will be assessed. The order of testing the muscle groups will be consistent. Manual muscle testing using the Medical Research Council ordinal scale will be conducted once using standardised positions. This scale ranges from 0 to 5, 0: no palpable or visible muscle contraction, up to 5: muscle can move against gravity and maximal resistance over full range of motion.
