New Pain Studies Report Mixed Treatment Results

A review of 13 randomized trials found virtual reality was associated with short-term reductions in cancer-related pain and anxiety, particularly during procedures and among children, though study limitations leave the evidence uncertain. By contrast, a Cochrane review of 20 trials found workplace ergonomic interventions generally made little to no difference to pain, function, recovery or sick leave for workers with arm, neck or shoulder complaints. Other early research explores how attention and technology may shape pain: a small study found simple tasks briefly reduced pain for some people with chronic pain but worsened it for others, while a separate VR experiment found eye-tracking signals could indicate mental workload less accurately in people with chronic pain than in healthy volunteers. Those findings do not establish that adaptive VR treats pain. A physical therapist featured in a news report said affirmations and calming her nervous system helped end recurring back pain, but her personal experience is not proof that the approach works generally.
