Abstract

This study tested a protocol for a randomized controlled trial of therapeutic versus placebo shoulder strapping as an adjuvant intervention early after stroke. Despite widespread use, there is little evidence of the efficacy or acceptability of shoulder strapping to improve arm function in patients with shoulder paresis following stroke. This study tested a protocol designed to trial shoulder strapping as an adjuvant therapy in patients with shoulder paresis after stroke and tested its acceptability for patients and clinical staff. A multiple-method design comprised one quantitative randomized, double-blind, placebo-controlled study and two qualitative exploratory investigations entailing patient interviews and staff surveys. Seventeen sub-acute stroke patients with shoulder paresis were recruited in London stroke service settings between November 2007 and December 2009. Outcomes from a 4-week therapeutic strapping protocol were compared with those of placebo strapping as an adjunct to conventional rehabilitation. Minimal adverse events and greater improvement in arm function (Action Research Arm Test) were seen with therapeutic compared with placebo strapping (effect size 0.34). Patients and staff found the strapping acceptable with minimal adverse effects. This study provided data for sample size calculation and demonstrated a workable research protocol to investigate the efficacy of shoulder strapping as an adjuvant intervention to routine rehabilitation for stroke patients. Small-scale findings continue to flag the importance of investigating this topic. The protocol is recommended for a definitive trial of shoulder strapping as an adjuvant intervention.
