Efficacy of Virtual Reality Rehabilitation after Spinal Cord Injury
Emilee Sanders, OTS
The Skinny:
Virtual reality (VR) rehabilitation may help individuals with spinal cord injury (SCI) improve motor function, motor skills, balance, and aerobic function and reduce pain either as a standalone intervention or in conjunction with rehabilitation therapies. This is a first systematic review of its kind concerning the effectiveness of VR and SCI in rehabilitation.
In the Weeds:
The systematic review includes 25 studies which contained randomized controlled trials, nonrandomized controlled trials, quasi experimental studies, and before and after studies.
Participant inclusion criteria: Male and Female participants aged 18-65 years with spinal cord injury (traumatic or nontraumatic) who participated in immersive or non immersive VR-based therapy.
Two reviewers extracted data based on participant characteristics, study characteristics, methodological details, VR effects, bias risk, size effects, statistical power, and limitations.
The reviewers used a p value of < 0.05 to assess whether the effects of VR-based rehabilitation were significant for the allotted category (motor function, aerobic function, pain, balance, or psychological aspects).
Bringing it home:
Studies showed a short-term improvement on motor function, aerobic performance, balance, pain, and psychological aspects. Long-term benefits were also shown for motor function, balance, and pain. Some subjective reports from participants included better mood, satisfaction improvements, and high enjoyment.

Overall, the studies did not report any negative effects due to VR therapy. In the studies that did report adverse effects, a small number of participants had a short-lived muscle pain, physical fatigue, and difficulties with attention span, and one study reported a few participants having simulator sickness.
Rating (0-5 rating scale):
3/5 This study was well done for what was possible. They found that only 7/25 studies had high quality evidence. Furthermore, the exact protocols/ VR-interventions were not provided, so it is hard to ensure the specific activities and exercises did not affect the outcomes. It would also be important to note if certain VR-based activities were more therapeutically beneficial than others.
The study states that due to this limited evidence, they recommend that VR-rehabilitation be used in conjunction with conventional therapies, and I agree based on the present findings.

In this article we’re looking at the difference between Inferential Current versus Transcutaneous Electric Nerve Stimulation (IFC vs TENS). Transcutaneous Electric Nerve Stimulation (TENS) TENS variations are often described by their technical characteristics: high frequency, low intensity (conventional TENS) or low frequency, high intensity (acupuncture-like TENS, AL-TENS) (Walsh et al., 2009).
