Musculoskeletal conditions are a very common, if not the most common, reason to visit the family doctor, comprising an estimated one-in-six to over half6 of all primary care visits. Under this umbrella of musculoskeletal conditions fall many different aliments: this paper will investigate chronic nonspecific low back pain and greater trochanter pain syndrome.
Boasting titles for greatest number of disability-years caused by a disease and most common non-communicable disease, one would hope that researchers and clinicians would thoroughly understand what causes this pervasive morbidity. Unfortunately, when it comes to chronic nonspecific low back pain (CNLBP), no clear pathoanatomic cause is attributed to the symptoms.
Low back pain is localized below the costal margin and above the inferior gluteal folds and is deemed chronic when it lasts for more than 12-weeks. Although most cases of low back pain seem to resolve prior to the 12-week mark, chronic low back pain is responsible for the vast majority of workers' compensation costs. In 90% of cases of chronic low back pain, clinicians cannot pinpoint the etiology, hence the 'non-specific' modifier.
Greater trochanter pain syndrome (GTPS) boasts a slightly less impressive resume - affecting a mere 10% to 25% of the general population. GTPS presents as lateral hip pain, specifically over the greater trochanter, and is worse when lying or bearing weight on that side.
It too has a plethora of potential aetiologies, and although it can be challenging to elucidate lateral hip pain's true etiology this clinical diagnosis comprises of trochanteric bursitis, gluteus medius and minimus tendinopathies, and external coxa saltans (commonly referred to as "snapping hip").
CNLBP and GTPS seem to coexist in about a third of the time and general treatment recommendations are similar. They range from analgesic medication to load management, though because between CNLBP and GTPS, a wide demographic is affected, treatments should be accessible and applicable to the wider population. Exercise therapies generally to meet these criteria. Exercise has also routinely demonstrated to be efficacious, cost-effective and low risk.
A multitude of different exercise modalities have routinely been shown to reduce chronic pain and improve physical function. Furthermore, specific exercises can be leveraged to treat chronic pain of broad aetiologies. Systematic reviews and meta-analyses alike have shown these to hold true in the realm of chronic non-specific low back pain as well. Commonly communicated is the relative paucity of research on GTPS, however, minimizing pain and performing strengthening and stretching exercises for the region appears to be a mainstay of the current therapy.
It is well known that exercise program adherence is a major issue when it comes to exercise interventions. A minimum level of adherence must be obtained for an exercise intervention to be efficacious. And when that level of adherence is attained in patients with CNLPB, exercise-based programs have shown to decrease pain and improve function. Similar results are show in the little amount of research on exercise therapies for GTPS, and in clinical practice it is assumed to be true.
Adherence is higher when people are highly supervised. So it is unsurprising that patients have higher rates of adherence after seeing their physiotherapist for extra 'booster' sessions. However, additional sessions with healthcare providers is not always feasible, due to high costs, poor accessibility, or unavailable providers, amongst other reasons. With the ever-increasing use of technology, though, patients can have somewhat similar care - such as guidance while doing exercises - through pre-recorded online videos. Some preliminary studies suggest that these online videos are able to increase patient adherence.
While many YouTube exercise rehabilitation videos are of high quality, there are also many that are not. This can leave the patient - even with an abundance of online resources - paradoxically without answers: unsure and unable to know what is relevant. Additionally, patients report better trust towards those who adequately understand their medical conditions, such as their healthcare team.
It would then be conceivable that physician-produced videos that are endorsed by the patient's healthcare team would alleviate this issue. Furthermore, it could circumvent the challenges associated with in-person care as well as alleviate some of the pitfalls of sifting through endless YouTube videos. The aim of this study was to investigate whether a patient education tool - an accompanying set of explanatory videos - will increase patient adherence when compared to prescribing an evidence-based, personalized set of exercises without these videos.
