For how we live.
Cochrane reviews found no trials specific to acute neck pain, and only moderate evidence that targeted exercise helps the chronic kind. Manipulation and mobilisation come out roughly even.
The commonest cause of spinning dizziness is loose inner-ear crystals. In trials the Epley manoeuvre cleared vertigo in 56% of people versus 21% with a sham, and guidelines advise against reaching for drugs.
A Cochrane review of 39 trials found a steroid injection lowered heel pain by about 6 points on a 100-point scale in the first month, and made no difference by six months. Most cases settle anyway.
A 503-patient trial found surgery no better than physiotherapy plus a steroid injection for frozen shoulder. A meta-analysis of 65 studies pointed to early intra-articular steroid as the one clear winner.
Manual lymphatic drainage is a real physiotherapy for swelling after breast-cancer treatment, where trials show modest, mixed benefit. For 'detoxing' or slimming a healthy body there is no evidence.
Balance starts slipping after the mid-50s. In 1,702 adults, those who could not hold a 10-second one-legged stance had 84% higher death risk. Specific exercise, done three times a week, measurably restores it.
A network meta-analysis found six treatments clearing the clinically important threshold in the short term. It also graded 98.6% of the evidence very low certainty, and found nothing that held up past a year.
The PROP OA trial found a 3.39-point gain on a 100-point score at six months. The effect on pain was larger than the effect overall, and both diminished by twelve months.
