Summary

The aim was to investigate the effect of Stellate Ganglion Blockade, which will be applied in addition to conventional physical therapy, on pain and functionality in patients with poststroke complex regional pain syndrome.

Detailed description

Post-stroke complex regional pain syndrome (CRPS) is relatively common in hemiplegic upper extremity. Complex regional Pain Syndrome Type 1 is often seen without any nerve damage especially post-stroke. This musculoskeletal disorder usually effects motor improvement, quality of life and Daily living activities. Besides Presence of CRPS is thought to be challenging on the way of rehabilitation process. However, disproportionate sympthatic nervous system activation, disinhibition of the descenden neuronal pathways are the mechanisms thought to be taken place in the etiopathogenesis of CRPS, it still remains unclear. Pharmacological agents, Physical Therapy techniques, exercise and injections are used to treat CRPS. Therefore post-stroke patients have co-morbidities and multi-drug usage, it should be take into account to treat them with physical therapy agents and interventional procedures. Stellat ganglion blockade is an interventional technique that is used to break the vicious circle of symphatetic activation of upper extremity in CRPS. However to the best of our knowledge there are not any study that evaluates the effect of stellat ganglion Blockade on CPRS combining conventional physical therapy. Total of 32 patients with post-stroke CPRS are going to be participated in the study. Patients are going to be divided into two groups. Group 1 is going to receive both onventional physical therapy, exercise (10 sessions) and stellat ganglion blockade and Group 2 is going to receive just conventional physical therapy program and exercise therapy (10 sessions). Participants are going to evaluate before treatment, 2 weeks and 12 weeks after the end of the therapy sessions. Visual analog scale (VAS), Brunnstroom stages of stroke recovery (BSSR), Fugl-meyer (FMUE) and Stroke spesific quality of life (SSQoL) are used to evaluate pain, functionality and quality of life.
