Splints and Orthotics of No Benefit for Achilles Tendinopathy

A recent systematic review with meta-analysis (for those non-science folks reading one of the highest quality studies you can have!) looked at a common treatment options for Achilles tendinopathy: exercise, orthotics and splinting.

What they Measured:

Researchers measured function, pain and quality of life for managing Achilles tendinopathy, and analysis 22 studies with over 1100 participants.

What they Found:

Exercise improved pain and function while splinting at night and wearing orthotics provided no benefit to pain, function, or quality of life.

What this Means:

If you’re dealing with Achilles tendinopathy then seek the guidance and assistance of a physiotherapist who can coach you with the best exercises that are appropriate for you and your injury to get you feeling and moving better!

Don’t waste your money or effort on things like orthotics or splints that make no difference in your pain, function, or quality of life !

Epidurals Do NOT Prolong Labor

The newest research provides evidence against the popular belief that it does.


A recent study published in the Journal of Obstetrics and Gynecology looked at the effect of an epidural on length of delivery.

Good News!

A recent study out of the Beth Israel Deaconells Medical Centre shows that having an epidural during the pushing stage of labor does NOT negatively affect the duration of labor.

Previous evidence and common sense from health professionals suggested a link between using an epidural and a longer second stage of labour (the stage where you push). It was therefore thought that there was a link between using an epidural and an increased risk of needing to intervene with an instrumental delivery (such as having to use forceps) or even having to have an emergency caesarean section.

The thought was that due to the numbing effects of the epidural, the pelvic floor muscles would not work optimally to push. Because of this, it has been common for doctors to limit pain meds flowing in an epidural if labour started to progress too slowly, meaning moms-to-be experienced more pain.

Good news is that this new study demonstrates that the epidural did not negatively impact delivery!

Let’s go over the study in more details:

The Study

The study conducted was a double-blind, randomized controlled trial. For those of you who aren’t in the research world, this translates to being a high quality study.

Between March 2015 and September 2015 400 women who had never before had a child completed the study. One group received an epidural during their second stage of labour, while the other group received a placebo epidural during this same stage. Length of vaginal delivery rate, incidence of episiotomy, position of the fetus at birth, as well as other measures of fetal well being were measured.

The Results

Findings of the study demonstrated that the epidural had NO effect on any of the above measures – length of delivery, incidence of episiotomy, position of the fetus at birth, or any other measure of fetal well being.

Not surprisingly, results also showed that the women in the control group (a placebo epidural) had a lot more pain than there control group counter parts.

What it All Means

This study provides some fantastic evidence to show that there is no down side to having an epidural during the second stage of labor. This is important as labor can be an incredibly painful experience, and the decision to have an epidural as a form of pain relief should lie with the patient in collaboration with her physician and/or midwife.

Key Takeaways

  • An epidural is a safe form of pain relief during the pushing stage of labor
  • It does not have an effect on length of delivery, or any measure of fetal well-being
  • The decision to have an epidural should lie with the patient in collaboration with her physican and/or midwife

First Sleep, then Coffee.

The Newest Research Links Pain and Sleepiness.


A new research study from Harvard Medical School brought together researchers from a pain and sleep background to look at an area not yet well studied: does sleep, or lack thereof, influence pain?

Researchers from Boston Children’s Hospital and Beth Israel Deaconess Medical Centre determined that decreased sleep increases pain sensitivity, though this isn’t all too surprising. What was surprising, however, was the role of alertness in pain sensitivity.  You see, researchers found that even with sleep loss, the more alert subjects were (for example had they been given caffeine), the less sensitive to pain they were.

In other words, the more sleep subjects had the less sensitive to pain they were; however, if they were deprived of sleep they experienced less sensitivity to pain than their other sleep deprived counterparts if they were given medications that promoted wakefulness, such as caffeine. Not only that, but these medications promoting wakefulness actually worked better than standard pain medications such as ibuprofen and morphine!

Let’s go through in more details:

The Study

Researchers looked at normal sleep cycles using EEG and EMG readings in mice. They then proceeded to deprive the mice of sleep. In a unique methodology, however, they tried to mimic the way most humans would lose sleep: they entertained them!

Essentially what this means is that they kept the mice subjects awake in a non-stressful manner (as opposed to making them run on the treadmill or fall off platforms as other studies frequently have done). Subject mice got to play with toys and do fun activities (similar to how us human counterparts may scroll through facebook, or watch late night TV). During there sleep deprived entertainment, researchers monitored the mice’s sleepiness, their levels of stress hormones (to make sure the mice weren’t stressed out) and tested their response to both painful and non-painful stimuli.

Pain sensitivity was measured by how long it took the subject to move away from a painful stimulus (heat, cold, pressure, or capsaicin – the agent in hot chili peppers), while non painful stimuli included looking at the subjects startle response to loud noises.

The Results

Findings of the study demonstrated that in otherwise healthy mice even just five consecutive days of moderate sleep deprivation significantly exacerbated pain sensitivity. This was specific to pain and common painkillers including ibuprofen and even morphine, a strong painkiller, did not block the pain hypersensitivity that was induced by the sleep loss.

However, researchers did find an interesting result that caffeine and modafinil, drugs that promote wakefulness, successfully blocked the pain hypersensitivity caused by both acute and chronic sleep loss.

What it All Means

This study is a great example of learning more about the sometimes complicated ties of lifestyle to both chronic and acute pain and tells us a lot about some new future areas of study.

Sleep is critical in all areas of our life, including managing our pain. Even acute sleep deprivation can worsen pain and can lead to a vicious cycle of pain and poor sleep quality. Therefore working on your sleep hygiene and ensuring you get sleep and avoid the distractions before bedtime can play an important role in feeling better.

Does this study mean you should go out and pump yourself up with wakefulness promoting drugs, like caffeine? No – remember, so far this study has only been done on mice – but it is an interesting note to think about. Because perhaps it is something we will need to consider in the future, as according to the authors, “This represents a new kind of analgesic that hadn’t been considered before, one that depends on the biological state of the animal…. Such drugs could help disrupt the chronic pain cycle, in which pain disrupts sleep, which then promotes pain, which further disrupts sleep.”

Key Takeaways

  • Acute and chronic sleep deprivation increases pain sensitivity
  • Painkillers such as ibuprofen and morphine may not block this hypersensitivity from sleep loss
  • Caffeine, and other wakefulness promoting agents, did seem to improve pain sensitivity when sleep deprivation had occurred.
