Virtual walking therapy in neuropathic spinal cord injury pain: a feasibility study.

STUDY DESIGN

A feasibility study.

OBJECTIVES

Chronic neuropathic pain is a prevalent comorbidity in patients with spinal cord injury (SCI), and current medical treatments remain unsatisfactory. New developments as virtual walking are emerging which has been established and further developed at our centre. This study aims to investigate the feasibility of our virtual walking setup in a small group of SCI patients.

SETTING

The study was conducted at the Swiss Paraplegic Centre in Nottwil, Switzerland.

METHODS

Four patients aged 22 to 60 years were observed during and after therapy. Three had complete paraplegia (levels Th4-Th8) with neuropathic at- and below-level pain, while one had incomplete paraplegia (Th10) with at-level pain. The primary outcome measured was satisfaction with acceptance of and adherence to virtual walking therapy, alongside suggestions for therapy improvements. Additionally, patients kept a pain diary and pain drawings to measure the extent of pain distribution and intensity before and after therapy. Therapy schedules included either two sessions per week for five weeks or five sessions per week for two weeks.

RESULTS

There was a sound satisfaction and good acceptance amongst participants. Support, duration, and number of sessions were perceived well and acceptable. Pain as a secondary outcome did not change during or after therapy in all but one patient which improved in pain intensity, pain quality as well as pain distribution.

CONCLUSION

Results suggest that our virtual walking setting is a feasible tool that should be further studied in patients with SCI-related chronic neuropathic pain.
