Only one in 10 treatments for lower back pain ‘are effective'
The majority of treatments for lower back pain may not be effective, according to a new review.
While the NHS advises that back pain will usually improve 'within a few weeks', this may seem like a lifetime to sufferers who will look for ways to alleviate their pain.
But a new study has found that only one in 10 treatments for lower back pain are effective, with those that improve symptoms only having 'slight' or 'small' effects on pain.
Experts found that evidence was 'inconclusive' for a number of popular treatments.
Researchers led by academics in Australia set out to examine the effectiveness of non-surgical back pain treatments in adults.
They looked at 301 trials examining 56 different treatments for lower back pain.
People involved with the studies reported pain intensity at the start of the trial and again after treatment.
Researchers also assessed the certainty of the evidence provided in the studies.
They found that just one treatment for acute low back pain and five treatments for chronic – or long-term – back pain were 'efficacious'.
These include non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, for short-term back pain.
For long-term back pain the treatments found to be effective were exercise, spinal manipulative therapy, taping, antidepressants and a type of drug called transient receptor potential vanilloid 1 (TRPV1).
But even these were only found to have 'slight' or 'small' reductions in pain compared with a placebo – or dummy drug.
'Best available evidence shows that one in 10 common non-surgical and non-interventional treatments for low back pain are efficacious, providing small analgesic effects beyond placebo,' the authors said.
They said that exercise, paracetamol and glucocorticoid injections 'probably provides little to no difference in pain' for acute lower back issues.
Antibiotics and anaesthetics were also found to be 'not efficacious' for long-term lower back problems.
Meanwhile the rest of the interventions studied had 'inconclusive evidence' so the authors called for more studies to examine the 'remaining uncertainty' surrounding a number of back pain treatments.
While the evidence was deemed to be inconclusive, the information available did point to some of these being effective for acute back pain.
For example the authors found that the certainty of the evidence for acupuncture was 'low' but the information that is available suggests that it may provide moderate reductions in pain for both short and long-term back pain.
And while massage is said to have large reductions in pain, the evidence surrounding this claim is 'very low'.
Other interventions where the evidence was deemed to be inconclusive include heat, TENS, opioids and muscle relaxants.
The authors, writing in BMJ Evidence-Based Medicine, added: 'Most non-surgical and non-interventional treatments for low back pain were not efficacious.
'Around 10% of non-surgical and non-interventional treatments provided small analgesic effects beyond placebo.
'For acute low back pain, there is moderate certainty evidence that NSAIDs are efficacious.
'For chronic low back pain, there is moderate certainty evidence that exercise, spinal manipulative therapy, taping, antidepressants, and TRPV1 agonists are efficacious.'

Younger women could have cervical screening every five years instead of three
The changes mean that, from next month, women aged 25 to 49 in England who are negative for human papillomavirus (HPV) will receive screening invites every five years. The move has been recommended by the UK National Screening Committee and is based on analysis from King's College London showing five-yearly screening is just as safe as three-yearly, with the same number of cancers found. HPV is a sexually-transmitted group of viruses which cause no symptoms. Around 13 high-risk types of HPV are known to cause 99.7% of all cervical cancers. As at present, any woman who has HPV or has a recent history of HPV will continue to be invited to more frequent screenings to check the virus has cleared and, if not, to check for cell changes in the cervix. In a written statement to Parliament, health minister Ashley Dalton said the new change 'increases the opportunities to test and recall women and people with a cervix who have HPV, while extending the cervical screening intervals from three to five years in England for individuals who have a negative HPV test. 'This will bring England's cervical screening intervals in line with those of Wales and Scotland.' She said the NHS screening programme in England provides all women between the ages of 25 and 64 'with the opportunity to be screened routinely to detect HPV infection or cervical abnormalities at an early, more treatable stage'. She added: 'The aim of the programme is to reduce the number of women who develop invasive cervical cancer and reduce the number who die from it.' Ms Dalton said testing negative for HPV means the chances of developing cancer within five years are very small, as it can take around 10 years or more from the time HPV is detected to developing cervical cancer. She added: 'Those who test positive for HPV are already being followed up with yearly testing. 'This is important to ensure that individuals are monitored for any early signs of cervical abnormalities and provided the necessary treatment.' Experts have been concerned about falling numbers of women under 50 attending cervical screening, with around a third in England not taking up their invitations. Dr Sue Mann, NHS national clinical director for women's health, said: 'Taking a more personalised approach to cervical screening will help ensure everyone eligible can make the most of these life-saving services, while sparing women appointments that they don't need. 'The NHS is following robust evidence on how often women need to be safely screened, and by putting invitations and reminders straight in women's pockets on their phones, we're making it easier than ever to take up screening appointments. 'Make sure you come forward for your screening when you're invited, even if it was weeks, months or years ago. If you think you are due but have not yet had an invitation, speak to your GP practice.' Michelle Mitchell, chief executive of Cancer Research UK, said: 'We welcome this change to cervical screening in England, which is the result of years of vital research to make screening more effective and has shown it is safe to extend the time between tests. 'Screening, alongside the roll out of the HPV vaccine – which Cancer Research UK scientists helped develop – have seen cervical cancer rates drop by around a quarter since the early 1990s, and we look forward to even more progress. 'If you notice any unusual changes for you, do not wait for a screening invitation – speak to your doctor.' Athena Lamnisos, chief executive of the Eve Appeal, said: 'We want every eligible person to feel empowered to attend a vaccination and cervical screening appointment when they are invited so we can achieve the brilliant ambition of eliminating cervical cancer.'

Major change to smear tests as women 'spared appointments they don't need'
Cervical cancer screenings will be less common for women aged 25 to 49 if they are shown to be low risk - low risk individuals will be able to wait five years between smear tests A major change to cervical cancer screening will mean younger women can have the smear test less often. Women aged 25 to 49 will no longer have to be tested every three years if their previous test shows no signs of the human papillomavirus (HPV), which is linked to cervical cancer. These women deemed at low risk will be able to wait five years between smear tests after the Joint Commission on Vaccination and Immunisation advised that this is safe. The change will come into force from next month. Dr Sue Mann, NHS national clinical director for women's health, said: 'Taking a more personalised approach to cervical screening will help ensure everyone eligible can make the most of these life-saving services, while sparing women appointments that they don't need.' Two people a day still die from cervical cancer in the UK and the disease claimed the life of Celebrity Big brother star Jade Goody in 2009. The move follows a recommendation by the UK National Screening Committee the five-year interval brings younger women into line with the approach already used for women aged 50 to 64 in England. Michelle Mitchell, chief executive of Cancer Research UK, said: "We welcome this change to cervical screening in England, which is the result of years of vital research to make screening more effective and has shown it is safe to extend the time between tests. Screening, alongside the roll out of the HPV vaccine have seen cervical cancer rates drop by around a quarter since the early 1990s, and we look forward to even more progress. "Beating cervical cancer means beating it for all, and we're committed to a future where almost no one develops this disease. If you notice any unusual changes for you, do not wait for a screening invitation - speak to your doctor." Currently cervical screening involves a medical professional inserting a soft brush to take a sample of cells from the cervix. In recent years cervical cancer rates have dropped for women in their 20s who received the HPV vaccine, but have increased for women aged 30 to 44. NHS England data shows that during 2023/24 only 68.8% of 25 to 64-year-olds were screened within the recommended period of time, compared to 68.7% the previous year. Embarrassment is thought to be a major reason uptake of screening is not higher and rates have fallen in recent years. The NHS has this week rolled-out digital invitations and reminders for cervical screening via the NHS App, as part of a new 'ping and book' service. Eligible women will first receive a notification through the app to alert them to book a screening appointment, followed by a text message if the app notification isn't opened. Letters will remain in place for those who need them. Dr Mann added: 'The NHS is following robust evidence on how often women need to be safely screened and by putting invitations and reminders straight in women's pockets on their phones, we're making it easier than ever to take up screening appointments.' Currently all women aged 25 to 64 are invited by letter to cervical screening to check the health of their cervix. It is not a test for cancer but looks for abnormal cells to help prevent cancer. A small sample of cells is taken from the cervix and checked for certain types of human papillomavirus (HPV) that can cause changes to the cells of your cervix. These are called "high risk" types of HPV. If these types of HPV are found, the sample is checked for any changes in the cells of your cervix. These can be treated before they get a chance to turn into cervical cancer. Cervical cancer causes 685 deaths a year in England. The move to five-year intervals for younger women brings England into line with Scotland and Wales. Louise Ansari, chief executive of Healthwatch England, said: "We welcome this change, which confirms that most women will not need to attend screening so frequently. 'Healthwatch research last year showed many women can find it an uncomfortable experience, and sometimes difficult to schedule in around their busy lives. Reducing the number of times they need to attend, alongside sensitive and empathetic approaches by health professionals, will make these important appointments easier to manage.' Women due for screening will still be invited at the interval in which they were advised of at the time of their last test. Only those who attend cervical screening on or after 1 July, and meet the clinical criteria, will have their next test due date set at five years. The NHS aims to eliminate cervical cancer by 2040 and is also rolling out the option of DIY swab kits. The World Health Organisation's definition of eliminating cervical cancer is to have an incidence rate of below 4 per 100,000 women.
