Muscle weakness is one of the most common and debilitating symptoms following a Spinal Cord Injury (SCI). Strength training is recommended as an effective means to increase muscular strength and improve function for individuals with long term SCI. In contrast, the strength training guidance for those with a recent (\<1 year) SCI is lacking. Therefore, this study aims to investigate the feasibility of a method of upper limb strengthening - Progressive Resistance Training (PRT) and its impact upon muscle strength and function.
The trial and recruitment will be conducted at the Queen Elizabeth National Spinal Injuries Unit (QENSIU), Glasgow. Individuals with tetraplegia and upper limb weakness will be randomly allocated to receive either a tailored progressive resistance training (PRT) programme alongside usual care or usual care alone. Up to 30 participants admitted to the QENSIU will be recruited to the study. They will be randomised to the intervention or control group. The intervention group will receive 8 weeks of PRT. 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 which contribute to achieving this goal. For each muscle group 3 sets of 8-10 repetitions will be carried out, resistance will be applied using wrist weights, free weights or resistance bands as required. Measurements of muscle strength and function will be assessed prior to, and following the study. Outcome measures: Manual muscle testing, Handheld Dynamometry, The Spinal Cord Independence Measure, The Action Research Arm Test.

Change in muscular strength - handheld dynamometry
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.
Time frame: Baseline, 8 weeks
Manual muscle testing
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.
Time frame: Baseline, 8 weeks
The Spinal Cord Independence Measure (SCIM III)
The Spinal Cord Independence Measure (SCIM III) is a measure of functional independence for individuals with SCI. It is composed of 19 items that assesses 3 domains: self-care, respiration and sphincter management and mobility. The total SCIM III scores range from 0 to 100. 0 represents total dependence, 100 represents complete independence. The blind assessor will score participants on the items for each subscale. The subscale 'self-care' exclusively relates to upper limb ability. SCIM III reflects important aspects of independence specific to the SCI population. Its use has been recommended for individuals with tetraplegia, changes within the self-care category relate to changes in upper limb function. Furthermore, it has been reported to be reliable and valid for patients with traumatic SCI.
Time frame: Baseline, 8 weeks
The Action Research Arm Test (ARAT)
Upper limb function will be assessed using The Action Research Arm Test (ARAT) following the standardised protocol outlined by Yozbatiran et al., (2008). The ARAT assesses participants ability to grasp, grip and pinch objects, and make gross motor movements. Standardised materials are required including a box with wooden blocks, alloy tubes, cups, marbles etc. Score for the ARAT ranges from 0-57 points, 57 points represents the best possible performance.
Time frame: Baseline, 8 weeks
Perception of ability
At the end of the intervention period, each participant in the intervention group will be asked to rate if their functional goal has changed on a 15-point scale from -7 'a very great deal worse', to +7 'a very great deal better'.
Time frame: 8 weeks
