Nevertheless, the combined administration of 43 hours of static stretching and 36 hours of NMES was more than administered during any previous trial (Borisova and Bohannon 2009). A recent study produced click here inconclusive evidence about the effectiveness of a combined intervention of electrical stimulation in conjunction with prolonged muscle stretch (using a splint) to treat and prevent wrist contracture (Leung et al 2012). Similarly, our results also showed no added benefit of electrical stimulation during static stretching of the shoulder and arm. The results of these multimodal approaches

to the problem of post-stroke arm contracture development are in line with the conclusion of a review (Katalinic et al 2011) that static stretch positioning procedures have little, if any, short or long term effects on muscle contracture (treatment effect ≤3 deg), pain, spasticity, or activity limitations. Although pooled data from studies investigating the effects of electrical stimulation suggested some treatment effects on functional

motor ability (Pomeroy et al 2006) and pain-free range of passive humeral lateral rotation in patients with residual arm motor capacity (Price and Pandyan 2000), we found no such results Selleckchem Nutlin 3 in our sample of patients without residual arm motor capacity. As the combined procedure did not result in any meaningful treatment effects, it suggests that application of muscle stretching or NMES alone as a monotherapeutic intervention will not have a clinically relevant impact in this subgroup of patients either. Research to date suggests that it is not possible to control or overcome (the emergence of) contractures and hypertonia using the current static arm muscle stretching procedures. Similarly, NMES of the antagonists of the muscles prone to shortening does not seem to provide additional benefits either. We therefore argue that these techniques should be discontinued in the treatment of patients with a poor prognosis for functional recovery. In this subgroup of patients it is becoming an increasingly difficult challenge

to find effective treatments that can prevent the development of the most common residual impairments such as contractures, Thiamine-diphosphate kinase hypertonia, and spasticity and its associated secondary problems such as shoulder pain and restrictions in performance of daily life activities. Further research is required to investigate what renders these interventions ineffective. The efficacy of other approaches, such as transcranial magnetic stimulation, NMES of the muscles prone to shortening (Goldspink et al 1991), or other combinations of techniques, could also be investigated. eAddenda: Table 4, 5, 6 (individual patient data) and Appendix 1 and 2.
