Effects of virtual walking on spinal cord injury-related neuropathic pain: A randomized, controlled trial.
Study Goal
The researchers aimed to determine if virtual walking could effectively treat spinal cord injury-related neuropathic pain and other pain types.
Results Summary
Virtual walking significantly reduced pain unpleasantness and certain sensory qualities of neuropathic pain but did not significantly differ from the control in overall pain severity reduction. The treatment showed pre- to post-reduction across all pain types, unlike the control.
Population
59 individuals with spinal cord injury and neuropathic pain.
Effective Dosage
20 minutes of virtual walking.
Duration
Single session (20 minutes).
Interactions
None mentioned.
| Intervention | Direction | Endpoint | Population | Dosage | Impact | Claim # |
|---|---|---|---|---|---|---|
virtual walking | no change | pain | individuals with SCI and neuropathic pain | - | no significant difference in change | #1 |
virtual walking | decrease | pain across all pain types | individuals with SCI and neuropathic pain | - | significant pre- to posttreatment reduction | #2 |
virtual walking | decrease | pain unpleasantness | individuals with SCI and neuropathic pain | - | significant reduction | #3 |
virtual walking | no change | neuropathic pain intensity | individuals with SCI and neuropathic pain | - | no significant reduction | #4 |
virtual walking | decrease | NP experienced as 'cold' | individuals with SCI and neuropathic pain | - | significantly reduced | #5 |
virtual walking | decrease | NP experienced as 'deep' | individuals with SCI and neuropathic pain | - | significantly reduced | #6 |
virtual walking | decrease | NP experienced with increased skin sensitivity | individuals with SCI and neuropathic pain | - | significantly reduced | #7 |
PURPOSE: This study is an examination of the efficacy of a virtual walking protocol to treat spinal cord injury (SCI)-related pain. METHOD: A total of 59 individuals with SCI and neuropathic pain (NP) were randomly assigned to receive 20 min of virtual walking, the treatment condition, or virtual wheeling, the control condition. Although having NP was a requirement to participate in the study, participants also underwent pain classification of up to 3 worst pain sites to also examine the effects of virtual walking on nonneuropathic pain. Pain outcomes included changes in pain severity across all pain types, NP unpleasantness, and severity of various sensory qualities of NP. DESIGN: This was a randomized, controlled, single-blinded trial. RESULTS: There was no significant difference in change in pain between groups, though there was a significant pre- to posttreatment reduction across all pain types in the virtual walking condition, but not the control condition. Specific to NP, there was a significant reduction in pain unpleasantness, but not neuropathic pain intensity. NP experienced as "cold," "deep," and with increased skin sensitivity were significantly reduced following virtual walking compared with the control condition. CONCLUSION: Results from this trial suggest that virtual walking treatment may benefit certain aspects of NP, such as associated unpleasantness, as well as certain sensory qualities of that pain. Efficacy of this treatment modality to reduce overall pain severity remains unclear, and may be modulated by other injury, individual, or personality characteristics.
