Acupuncture - No important effect over sham, no evidence for subgroups who might benefit, further research unlikely to change recommendation
Orthotics, belts, corsets, rocker sole shoes - Very limited clinical evidence of benefit
Traction - Very limited clinical evidence of benefit
Electrotherapies:
PENS: insufficient evidence as recommendation would be a significant change in clinical practice
TENS: conflicting evidence
Interferential: evidence of no clinical benefit
Therapeutic ultrasound: insufficient evidence of clinical benefit
