   Strength work at the office keeps neck and shoulder pain away

   A systematic review of 24 randomised trials found workplace exercise programmes, especially strength work targeting the neck, shoulders and upper limbs, reduced pain and helped prevent musculoskeletal disorders in workers.

   ⚠What it shows: Encouraging but broad-brush: a sweep of 24 trials where workers were assigned at random to exercise programmes or not, reported without pooled numbers, so the direction of the effect is clearer than its size. The programmes varied a lot between studies, which makes the ideal routine hard to pin down.Systematic review · Aten Primaria

   Back pain shows up in the fascia: thicker, stiffer, denser on scans

   Pooled imaging from 14 studies shows the thoracolumbar fascia, the broad connective tissue sheet of the lower back, is thicker, stiffer and more echogenic in people with low back pain than in pain-free controls. Greater fascial thickening also correlated with higher pain ratings.

   ⚠What it shows: A real and consistent difference, but a snapshot: results pooled from 14 imaging studies comparing people with and without back pain cannot say whether the fascia changes cause the pain or follow from it. The stiffness and density findings also rest on just 3 studies each.Systematic review · Sports Med Open

   Exercise still eases chronic low back pain after 60

   Exercise therapy meaningfully reduced pain and disability and improved both physical and mental quality of life in adults aged 60 and over with chronic low back pain, across 18 randomised trials involving 989 people. Effects on mobility were less certain.

   ⚠What it shows: Strong enough to matter: results pooled from 18 trials in 989 adults aged 60 and over, and the included studies were of relatively high quality. The mobility findings were shakier and the authors say more trials are needed to confirm them.Meta-analysis · J Orthop Surg Res

   Yoga eases back pain, but no better than standard physio exercise

   Across 18 randomised trials, yoga reduced chronic low back pain versus no exercise for up to 6 to 7 months and improved disability for up to 12 months, but it was no better than physical therapy exercise on either outcome, and quality of life did not improve.

   ⚠What it shows: Believable but unglamorous: results pooled from 18 trials, with the strength of the evidence ranging from very low to moderate. The pain benefit had faded by the 12-month mark, and yoga showed no edge over ordinary exercise at any point.Meta-analysis · PLoS One

   Softer landings, not new shoes, may protect runners' knees

   Runners retrained to land more softly had roughly two-thirds lower risk of knee injury in one trial of 320 people. Meanwhile footwear choices, graduated running programmes, multicomponent exercise and injury-prevention education showed no influence on knee injury risk across 17 other prevention trials.

   ⚠What it shows: Promising but fragile: the standout result comes from a single trial of 320 runners, rated low certainty within a wider sweep of 30 trials in new and recreational runners. It needs repeating before it counts as anything like settled.Meta-analysis · Br J Sports Med

   Kegels ease low back pain, not just bladder trouble

   Across 19 randomised trials (456 people doing the exercises, 470 controls), pelvic floor muscle strengthening reduced low back pain intensity more than control care, with the biggest reductions in postpartum and pregnant women.

   ⚠What it shows: Decent evidence with a wobble: results pooled from 19 trials all pointed towards less pain after pelvic floor training, but the trials disagreed with each other a lot, so the true size of the benefit is uncertain. The clearest signal came from women during and after pregnancy, so it may not transfer equally to everyone else.Meta-analysis · Neurol Sci

   Rest was the old prescription for chronic pain; the evidence backs movement

   An overview of 21 Cochrane reviews covering 381 studies and 37,143 adults with chronic pain found exercise caused few adverse events and tended to improve pain severity and physical function, though most effects were small to moderate and the underlying evidence quality was low.

   ⚠What it shows: Reassuring on safety, less certain on how much relief to expect: this sweep of all the studies covered 381 trials with 37,143 adults, but most individual trials had fewer than 50 people and rarely followed anyone beyond three to six months. The clearest signal is that exercise did little harm.Meta-analysis · Cochrane Database Syst Rev

   Exercise beats usual care for chronic low back pain, by a margin patients can feel

   A Cochrane review of 249 trials found exercise reduced chronic low back pain by a clinically important margin compared with no treatment, usual care or placebo, and is probably more effective than education alone or non-exercise physical therapy. Improvements in day-to-day function were smaller and fell short of the threshold for clinical importance.

   ⚠What it shows: About as trustworthy as back pain evidence gets: a Cochrane sweep of 249 trials with moderate certainty in the main result. Pain relief cleared the bar for a difference patients would feel, but gains in daily function were small, and most trials could not hide from participants which treatment they received.Meta-analysis · Cochrane Database Syst Rev

   Your knees squash a little after a run, then bounce back

   MRI studies show knee cartilage thickness and volume dip by roughly 3.3% to 4.9% immediately after running, but the changes appear transient, with some measures back to baseline within 91 minutes and existing cartilage defects unchanged within 48 hours. Reviewers concluded a single bout of running does not appear detrimental to knee cartilage.

   ⚠What it shows: Reassuring but far from settled: a sweep of 24 imaging studies covering 446 knees, and the authors rate the certainty of the evidence as very low, with only a third of studies at low risk of bias. It also only examined single runs, so it says nothing about years of training or people with existing knee problems.Meta-analysis · Osteoarthritis Cartilage

    Heavy weights offer no extra relief for arthritic knees

    Pooled data from ten trials in 892 adults with knee osteoarthritis found high-intensity strength training was no better than lighter training or routine care for knee pain, function, stiffness or quality of life, with a comparable rate of adverse events.

    ⚠What it shows: A null you can actually use: results pooled from ten trials in 892 adults with knee osteoarthritis found lighter strength work matched heavy training on almost every measure, including safety. The comparison lumped lighter training together with routine care, so it cannot rank those two against each other.Meta-analysis · Am J Phys Med Rehabil

    Pool or gym floor: knee arthritis exercise worked either way

    In a small 8-week trial, 29 women aged 40 to 70 with knee osteoarthritis improved similarly in pain, function, strength and fear of movement whether they did closed chain exercises in water or on land. Only the 40-metre walk test favoured the land group.

    ⚠What it shows: Useful but small: a trial of 29 women assigned at random to pool or land sessions for 8 weeks, so it cannot speak for men or for longer-term joint outcomes. Both groups improved, and only one walking test told them apart.Study · Health Sci Rep

    Achilles tendons with tendinopathy shrank right after isometric exercise

    Across 12 pooled studies, people with midportion Achilles tendinopathy showed an immediate large reduction in tendon volume after isometric exercise, while healthy Achilles tendons kept their volume after acute loading.

    ⚠What it shows: Interesting but early: results pooled from 12 small studies of healthy and painful Achilles tendons, and several of the changes did not reach statistical significance. Whether a shrinking tendon means anything for pain or recovery is still unknown.Meta-analysis · J Biomech

    Collagen supplements eased knee osteoarthritis pain across 11 trials

    Oral collagen supplements improved both pain and function in people with knee osteoarthritis across 11 randomised trials totalling 870 participants, with pain scores improving by 13.63 points more than placebo and function by 6.46 points, improvements the authors call statistically and clinically noteworthy.

    ⚠What it shows: Reasonably strong for a supplement: results pooled from 11 trials in 870 people with knee osteoarthritis all pointed the same way, favouring collagen over placebo. The trials disagreed with each other on how large the benefit is, so the exact size remains uncertain.Meta-analysis · Clin Exp Rheumatol

    Heat eases arthritic hands, but the type of heat matters

    Across nine pooled trials in 627 people, heat therapy reduced short-term pain and improved grip strength in hand osteoarthritis. Combined approaches such as paraffin and mud treatments outperformed heated gloves alone.

    ⚠What it shows: Solid for the short term: results pooled from nine trials in 627 people back the pain relief and grip gains, but the trials delivered heat in different ways and only tracked people briefly. Nobody knows yet whether the benefit lasts.Meta-analysis · J Rehabil Med

    Impact plus lifting builds bone density in older adults

    Exercise significantly increased bone mineral density at the lumbar spine and femoral neck in older adults, in a meta-analysis of 19 randomised trials with 1577 participants. Programmes combining impact activity with resistance training loading, and odd-impact protocols, were the effective types; low-impact and resistance-only exercise showed no significant change.

    ⚠What it shows: Strong by exercise-science standards: 19 trials with 1577 older adults, moderate to high quality, and no sign that negative results were left unpublished. The bone gains were small and results for some exercise types disagreed with each other, so the ideal programme is not yet settled.Meta-analysis · Age (Dordr)

    For chronic back pain, exercise dose matters more than exercise type

    Exercise brings small but significant reductions in pain and disability for people with chronic low back pain, and of the eight programme and trial features examined, only dosage, the total amount of exercise delivered, was linked to how well it worked.

    ⚠What it shows: Solid footing: this pooled the randomised trials of exercise for chronic low back pain and the benefit, though small, held up. It compared whole studies rather than individual patients, so it cannot say which kind of person benefits most, and the search only ran to 2008.Meta-analysis · Phys Ther

    For knee osteoarthritis pain, non-weight-bearing strength work led the field

    In a meta-analysis of eight randomised trials, short-term exercise produced a large reduction in knee osteoarthritis pain overall (SMD -0.94), and non-weight-bearing strengthening had the biggest effect (-1.42) compared with weight-bearing strengthening (-0.70) and aerobic exercise (-0.45).

    ⚠What it shows: Pooled data from only eight randomised trials, all using programmes of more than three sessions a week for up to eight weeks, so this speaks to short-term pain relief only; the subgroup comparison is indirect and the review dates from 2013.Meta-analysis · Clin Rehabil

    For chronic back pain, only movement held up long term

    A systematic review of 85 studies on chronic non-specific low back pain found that only movement therapy showed evidence of long-term effectiveness. Bed rest, TENS, massage, spine supports, back schools and antidepressants showed no evident effectiveness, while injections, NSAIDs, heat and opioids helped only in the short term.

    ⚠What it shows: Review of German and English literature from 2004 to 2015; therapies were assessed as broad categories, 'long term' meant beyond 6 weeks, and the evidence base is now around a decade old.Meta-analysis · Orthopade

    Cognitive functional therapy may not beat manual therapy for back pain

    Pooling five randomised trials (n = 507), cognitive functional therapy may be no more effective than manual therapy plus core exercises for reducing pain and disability in chronic low back pain, with the pooled estimates so imprecise that the certainty of evidence was rated very low. No adverse events were reported.

    ⚠What it shows: Systematic review and meta-analysis of 15 identified trials, of which only 5 provided data (n = 507; 262 cognitive functional therapy, 245 control); all studies were judged at high risk of bias, confidence intervals were extremely wide, and 9 trials were still ongoing.Meta-analysis · J Orthop Sports Phys Ther

    Supplements trail the drug for knee arthritis pain

    In a network meta-analysis of 23 randomised trials in knee osteoarthritis, celecoxib ranked highest for pain on the visual analogue scale (mean difference -0.48, 95% CI -0.78 to -0.17) and for WOMAC total score, followed by glucosamine/chondroitin; krill oil ranked top on the WOMAC pain subscale, while probiotics and metformin had the most favourable safety rankings. Certainty for most of these adjuvant comparisons was low or very low.

    ⚠What it shows: Network meta-analysis of 23 RCTs with no direct head-to-head trials between the adjuvant options; GRADE certainty for most supplement comparisons was low or very low, mainly from severe imprecision, so the rankings are provisional rather than a league table.Systematic review · Front Med (Lausanne)

    Back pain adherence coaching: small gains, unclear why

    In a meta-analysis of 14 randomised trials covering 1,233 adults with non-specific low back pain, strategies bolted onto exercise programmes to improve adherence showed no clear effect on adherence itself, yet pain and function improved slightly in the medium term on moderate-certainty evidence.

    ⚠What it shows: Fourteen randomised trials, 1,233 adults with non-specific low back pain; risk of bias was low in only six trials, adherence was measured inconsistently (device data in three trials, questionnaires in four), and certainty ranged from moderate to very low.Review · Musculoskelet Sci Pract

    In a systematic review of ten moderate-to-high quality trials in knee osteoarthritis, quadriceps strengthening reduced pain and improved function, and outperformed proprioceptive training. No one strengthening method beat the others.

    Pain does not track knee load, review finds

    Pooling 183 studies of people with knee osteoarthritis, walking produced the greatest knee loading and stair ascent the most pain, while sit-to-stand was lowest on both; during walking, higher knee loading was correlated with less pain (r = -0.507).

    ⚠What it shows: Systematic review and meta-analysis of 183 studies, but the loading differences across activities were mostly non-significant apart from sit-to-stand, the populations and methods were highly heterogeneous, and many studies measured only one activity: usually walking. The loading-pain correlation is cross-study association, not cause.Meta-analysis · Clin Biomech (Bristol)

    Walking and tai chi ease knee osteoarthritis pain

    A meta-analysis of 24 studies (1,972 participants, 71.46% female) found that low-intensity physical activity, Baduanjin, tai chi, walking and general activity, significantly reduced knee osteoarthritis pain (d = -0.65) and stiffness (d = -0.71) and improved physical function (d = -0.58) in middle-aged and older adults.

    ⚠What it shows: Pooled from 24 trials of mixed quality (assessed with the Cochrane risk-of-bias tool) in middle-aged and older adults with knee osteoarthritis, mostly women; exercise trials cannot blind participants, so effect sizes for self-reported pain may be flattered, and the review does not establish which modality is best.Meta-analysis · J Aging Phys Act
