Urine output was measured each time over a one-hour period. Prior to all one-hour collection

periods, participants’ bladders were emptied via a catheter. If intermittent self-catheterisations were used for bladder management, an indwelling catheter was temporarily inserted to ensure consistency between measurements. In addition, fluid intake was restricted for three hours prior to the collection period NSC 683864 nmr according to normal recommended daily intake for weight (Spinal Cord Medicine Consortium 1998). Where possible, participants’ bladder management remained constant throughout the trial although two participants changed bladder management from indwelling catheters – one to a suprapubic catheter and the other to intermittent self-catherisations – for reasons unrelated to the trial. Spasticity was measured before and after the experimental learn more and control phases of the trial using the Ashworth Scale (Cardenas et al 2007). Measurements were performed in the supine position for quadriceps, hamstrings, plantarflexor, and hip adductor muscles (0–4). Scores for each muscle group of the left and right legs were tallied and treated as one overall measure of lower limb spasticity (0–32) as recommended by others (Hobbelen et al 2012). Lower limb swelling was measured before and after the two phases of the trial using the ‘Leg-o-meter’, a reliable and valid tool that uses a tape measure

to quantify leg circumference (Berard and Zuccarelli 2000). Circumferential measures were taken 13 cm from the base of the heel, directly posterior to the medial malleoli. Participants were asked to complete the Patient Reported Impact of Spasticity Measure (PRISM) questionnaire before and after the control

and experimental phases. The questionnaire explores participants’ experiences of abnormal muscle control or involuntary muscle movement over the found preceding week. It asks participants to rate their abnormal muscle control or involuntary movement for 41 scenarios on a 5-point scale ranging from 0 (‘never true for me’) to 4 (‘very often true for me’) with a maximal possible score of 164 reflecting severe spasticity. Its reliability has been established (Cook et al 2007). At the end of the trial, participants were asked to rate their perceptions about the overall effects of FES cycling using a 15-point Global Impression of Change Scale anchored at –7 by ‘markedly worse’ and at +7 by ‘markedly better’ (Schneider et al 1997). In addition, they were also asked to rate the inconvenience of the FES cycling phase of the trial on a 10-cm Visual Analogue Scale anchored at one end with 0 reflecting ‘not at all inconvenient’ and at the other end with 10 reflecting ‘extremely inconvenient’. Participants were also asked open-ended questions to explore any perceived deleterious or beneficial effects of the FES cycling. Change data (pre to post difference) for each phase were used to Libraries derive point estimates of the differences between the experimental and control phases.
