   Exercise eases chronic back pain while the stress hormone rises

   Pooled results from four trials in adults with chronic low back pain found that exercise programmes lasting six weeks or more reduced pain, yet serum cortisol levels went up rather than down.

   ⚠What it shows: An early signal only: four trials with 169 people between them, and the studies disagreed with each other on how big both effects were. Whether the cortisol rise matters for recovery is simply not known yet.Meta-analysis · Pain Manag

   Diet plus lifting tops the rankings for keeping muscle with osteoarthritis

   Pooled rankings from 34 randomised trials in overweight or obese adults with lower-limb osteoarthritis placed diet plus resistance exercise as the most effective approach for muscle mass, resistance exercise alone for muscle strength, and aerobic exercise alone for walking speed.

   ⚠What it shows: Strong as evidence goes because it pools 34 randomised trials, but the rankings come from comparing treatments across different studies rather than head to head, and the trials used a mix of diets and exercise programmes, so the exact ordering is less certain than the overall message.Meta-analysis · Nutrients

   Light weights with a cuff matched heavy training in arthritic joints

   In pooled trials of people with osteoarthritis and rheumatoid arthritis, mostly women, low-load resistance training with blood flow restriction produced similar gains in muscle strength, muscle mass and functionality to moderate and high-intensity training, and outperformed low-load training without restriction on knee extension strength.

   ⚠What it shows: Promising but thin: only five trials made the cut, mostly in women with arthritis, and the strength results varied somewhat between studies. Enough to call the approach promising, not enough to call it proven.Systematic review · PLoS One

   Exercise may ease office workers' back pain, but the proof is thin

   Pooling 4 randomised trials in 263 office workers with chronic low back pain, exercise interventions may reduce pain in the short term; the certainty of the evidence was rated very low and no trial measured work productivity.

   ⚠What it shows: A weak signal, not a verdict: only 4 trials with 263 office workers could be pooled, the reviewers rated the pain evidence very low certainty, and not one study measured whether people actually functioned better at work.Study · J Occup Health

   Medical cannabis eases chronic pain only slightly, and dizziness comes with it

   Pooled results from 32 randomised trials in 5174 adults with chronic pain show non-inhaled medical cannabis gives a small improvement in pain relief, with 10% more patients reaching a meaningful reduction than on placebo, plus very small gains in physical functioning and sleep quality. It also raised the risk of transient side effects including dizziness, drowsiness, nausea, vomiting and impaired attention.

   ⚠What it shows: About as solid as pain evidence gets: results pooled from 32 trials in 5174 adults, rated moderate to high certainty. The benefits are genuinely small though, follow-up lasted at most 5.5 months, and dizziness became far more common in trials running 3 months or longer.Meta-analysis · BMJ

   Tai chi and yoga outperformed standard rehab for chronic low back pain

   In a network comparison of 75 randomised trials with 5,254 participants, tai chi, yoga, Pilates and sling exercise eased chronic low back pain more than conventional rehabilitation, while yoga and core or stabilisation exercises did most for physical function.

   ⚠What it shows: Encouraging but not settled: results pooled and ranked across 75 trials in 5,254 people, yet many of the underlying trials were small and of mixed quality, so the authors stop short of crowning a single best regimen.Meta-analysis · Front Public Health

   Pilates helps back pain, but no better than other exercise

   Across 10 randomised trials in 510 people with nonspecific low back pain, Pilates reduced pain and disability more than minimal intervention, mostly with medium-sized effects, but there is no conclusive evidence it beats other forms of exercise.

   ⚠What it shows: Fairly trustworthy as far as it goes: a sweep of all the studies on this pulled together 10 trials with 510 people, rating the evidence low to moderate quality. It shows Pilates beats doing very little, not that it beats other exercise.Systematic review · Spine (Phila Pa 1976)

   Magnetic pulses may ease low back pain, on thin evidence

   Pooled results from 6 randomised trials suggest repetitive peripheral magnetic stimulation reduces pain intensity and functional disability in people with low back pain compared with sham or other therapy, though fear of movement did not improve and the evidence was rated very low to low quality.

   ⚠What it shows: A hint, not proof: results pooled from just 6 small trials totalling 139 people, and the reviewers themselves rated the evidence very low to low quality. Promising on paper, a long way from settled.Meta-analysis · Arch Phys Med Rehabil

   The unfashionable back brace holds up in pooled trials

   A meta-analysis of 13 randomised trials found that back braces and other lumbar orthoses, worn for two weeks or longer, significantly reduced low back pain and its associated disability.

   ⚠What it shows: Encouraging but light on detail: results pooled from 13 trials of people with low back pain, and the paper reports that pain and disability improved without saying by how much. Braces were often used alongside other therapies, so the brace alone may not deserve all the credit.Meta-analysis · J Back Musculoskelet Rehabil

    Your tendon can feel better without looking better on a scan

    Exercise therapy for tendinopathy works without the tendon visibly changing: a review of 20 studies in 625 patients found strong evidence refuting structural change as the explanation for improvement after eccentric training. Only heavy-slow resistance training showed moderate evidence of structural change.

    ⚠What it shows: Strong on what it rules out, silent on what the real mechanism is: a sweep of 20 studies covering 625 tendinopathy patients, though the studies were too varied to pool their numbers. The searches ran to 2012, so newer imaging work could refine the picture.Systematic review · Br J Sports Med

    Gentle aerobic exercise eased fibromyalgia pain, no hard intensity needed

    Pooled results from 28 randomised trials covering 2,494 people with fibromyalgia found aerobic exercise modestly reduced pain, fatigue, depressed mood and quality-of-life limitations and improved physical fitness. Pain fell with both land-based and water-based exercise of slight to moderate intensity, two or three times per week.

    ⚠What it shows: About as good as this evidence gets: results pooled from 28 randomised trials in 2,494 people with fibromyalgia, and the improvements held up when the authors tested for bias, though each one was modest in size. Few trials described their exercise programmes in detail, so which format works best is still unresolved.Meta-analysis · Arthritis Res Ther

    Screen-guided rehab shows early promise for arthritic knee pain

    In a systematic review of randomised trials, interactive digital rehabilitation may improve pain-related functioning and lower pain intensity at 6-8 weeks in knee osteoarthritis, though certainty was low. After knee replacement it may aid functioning but made little to no difference to pain.

    ⚠What it shows: Promising but thin: trials were small, ranging from 36 to 306 people, most followed people for 3 months or less, and reviewers rated the key evidence low certainty. Better studies could shrink or erase the benefit.Meta-analysis · J Med Internet Res

    Moving more may be the treatment for fear of moving in chronic back pain

    In pooled results from eight trials with 854 adults with nonspecific chronic low back pain, exercise on its own reduced fear of movement more than passive care or usual care, by more than the smallest amount patients would notice. Certainty in the evidence was rated low.

    ⚠What it shows: Encouraging but shaky: eight trials with 854 people pointed the same broad way, yet the studies disagreed with each other a great deal and the overall evidence was rated low certainty. The authors themselves call it a trend, not a consistent effect.Review · Eur Spine J

    Exercise keeps bad backs at work, and the type barely matters

    Exercise programmes cut the odds of long-term work disability by about a third compared with usual care in people with persistent non-specific low back pain, across pooled results from 23 randomised trials. No single type of exercise proved better than another.

    ⚠What it shows: Solid but slow-burn evidence: results pooled from 23 trials found exercise beat usual care only in the long term, with nothing significant in the short or medium term and no clear winner among exercise types. The search also stops at 2008, so this is a mature rather than fresh finding.Meta-analysis · J Rehabil Med

    Yoga plus education tops the list for back pain with low mood

    Across five randomised trials in 834 people living with both chronic low back pain and depressive symptoms, yoga combined with education showed the largest improvements in pain and mood versus usual care. The certainty of the evidence was rated low to very low.

    ⚠What it shows: A pointer, not a verdict: just five trials covering 834 people fed the comparison, and the authors rate their own certainty as low to very low. The yoga result rests on a thin slice of that evidence.Meta-analysis · Sci Rep

    Mood and fear predict lasting back pain better than how you move

    A pooled review of fifteen studies found that depression, distress and fear of movement predicted whether non-specific low back pain became persistent, while physical factors such as trunk movement showed limited and inconclusive evidence. The certainty of the evidence was rated low across the board.

    ⚠What it shows: Treat this as a strong lead rather than a verdict: a sweep of fifteen studies, one covering 15,778 people, found the psychological links, but the authors rate the certainty of evidence as low to very low throughout. It shows prediction, not proof that treating mood or fear prevents lasting pain.Meta-analysis · Eur J Pain

    Muscle-zapping machines only help arthritic knees when paired with exercise

    Pooled across eight randomised trials, neuromuscular electrical stimulation did not reliably improve pain, disability, quadriceps strength or walking distance in knee osteoarthritis. Added to structured exercise, though, it reduced pain more than exercise alone.

    ⚠What it shows: Take the headline null seriously and the bright spots gently: only eight trials fed this pooled analysis, and the one clear functional gain came largely from a single study. The pain benefit alongside exercise looks the most credible use, not the device on its own.Study · Orthop Rev (Pavia)

    Pilates eases chronic low back pain in women, and menopause does not blunt it

    In pooled randomised trials, Pilates produced large improvements in pain and everyday function for women with chronic low back pain, and postmenopausal women benefited as much as younger women.

    ⚠What it shows: Consistent benefit, but treat the size with care: pooled effects this large often shrink as bigger trials arrive, and the comparison groups ranged from doing nothing to other treatments, so some of the gain may reflect structured exercise of any kind. The review also does not report how many women took part overall.Study · J Back Musculoskelet Rehabil

    Strength training on isokinetic machines eases arthritic knees

    Across 46 randomised trials in 2,860 people with knee osteoarthritis, isokinetic strength training improved knee muscle strength, range of motion and knee function scores, and reduced pain and stiffness compared with control treatments.

    ⚠What it shows: Encouraging but shaky: results pooled from 46 trials in 2,860 people with knee osteoarthritis all pointed the same way, yet the review's own authors rated the underlying evidence as poor because the trials disagreed with each other and many gave imprecise results. Bigger, better trials are still needed before this counts as settled.Meta-analysis · J Orthop Surg Res

    Hip work helps wobbly ankles only alongside ankle rehab

    Pooled results from nine randomised trials found hip strengthening improved balance reach distances, self-reported ankle stability scores and hip abductor strength in people with chronic ankle instability. In subgroup analysis, the balance gains only appeared when hip work was added to ankle rehabilitation; hip strengthening on its own beat neither no training nor ankle rehab alone.

    ⚠What it shows: Suggestive rather than settled: results pooled from nine trials that the reviewers describe as small and low quality, so the size of any benefit is uncertain. Everyone taking part already had a repeatedly unstable ankle, so this says nothing about preventing a first sprain.Meta-analysis · Complement Ther Med

    Workplace exercise schemes eased neck and shoulder pain, not low back pain

    Pooling trials of workplace physical activity programmes, employees in the intervention groups reported less general musculoskeletal pain (standardised difference -0.40) and less neck and shoulder pain (-0.37) than comparison groups, while the few studies of low back pain and of arm, elbow, wrist, hand or finger pain showed no clear evidence of benefit.

    ⚠What it shows: Reasonably solid for the neck and shoulders: results pooled from workplace trials published between 1990 and March 2013, each comparing employees given an exercise programme with employees who were not. Pain was reported by the employees themselves, and there were too few trials on the low back, arms and hands to say anything either way.Meta-analysis · Workplace Health Saf

    Core work is no better than any other exercise for back pain

    Pooled data from 29 studies found stabilisation or core stability exercises produced statistically significant but clinically insignificant long-term improvements in non-specific low back pain and disability compared with any alternative treatment or control, with mean differences of -6.39 for pain and -3.92 for disability on a 0 to 100 scale. Compared with other forms of active exercise, there was no statistical or clinical difference.

    ⚠What it shows: Strong evidence and unusually consistent: results pooled from 29 studies covering more than 2,000 people for pain and for disability, with the studies largely agreeing and rated of high quality at long-term follow-up. The authors judge further research unlikely to change the conclusion, though it does not tell you which exercise any individual will stick with.Meta-analysis · BMC Musculoskelet Disord

    Knee arthritis pain fell sharply with machine-based strength training

    Pooled results from nine trials in 696 people with knee osteoarthritis found isokinetic strength training, done on machines that control movement speed, produced a large improvement in pain and a moderate one in disability, and it was well tolerated.

    ⚠What it shows: Encouraging but not settled: results pooled from nine trials covering 696 people with knee osteoarthritis, all judged low to moderate quality. The programmes and outcome measures varied so much that the authors say firm guidance on how to deliver this training is not yet possible.Meta-analysis · Ann Phys Rehabil Med

    Fast reps with lighter weights work best for arthritic knees

    A pooled analysis of 46 randomised trials in 3463 people with knee osteoarthritis ranked high-speed resistance training as the most effective type for easing pain and stiffness and improving function. For pain and function, moderate loads of 43 to 47% of one-rep max appeared optimal.

    ⚠What it shows: Strong as exercise evidence goes: results pooled from 46 trials in 3463 people with knee osteoarthritis. The trials varied a lot in how they ran the training, so the precise dose numbers are best read as ballpark targets rather than rules.Meta-analysis · BMC Musculoskelet Disord
