- Abstract
- Objective: the aim of our study is to investigate the alterations in motor control variables on a quantitative level in patients suffering from low back pain in order to understand the differences between these individuals and healthy ones. Methods: during this study we used multiple scientific databases such as pubmed, embase and google scholar in order to find the needed literature as well as results. We used specific keywords (according to our PICO) accompanied with coordinating conjunctions such as “AND” and “OR” while following the specific database format to come up with appropriate research equations. Studies found were scanned to make sure they follow our inclusion/exclusion criteria before presenting their results. This study focused mainly on two outcomes of motor control which are muscle activation and kinematics. Results: according to the results found in the literature, we notice several differences between LBP patients and healthy ones. When it comes to muscular activity, several studies have showed that during movement different muscles were recruited at different intensities; notably the multifidus muscle (MF), erector spinae (ES) being greatly activated when compared to healthy individuals. Onset latency was also delayed in patients with LBP for the following groups: MF, ES, internal oblique/transverse abdominus (IO/TrA), external oblique (EO) and rectus abdominus (RA). On the other hand, kinematics results also varied between LBP patients and healthy ones; there was a noticeable decline in angle and angular velocity in patients with LBP as well as overall thoracic and lumbar range of motion (ROM). Conclusion: it is clear when looking at the results found that there are many alterations in the motor control of LBP patients. The results found in the literature also showed many contradictions which were potentially due to the body’s innate capacity to adapt differently when faced with obstacles (such as pain in this case). This makes it harder for practitioners to come up with a specific consensus on the matter as well as locating specific alterations in outcomes (specific muscle groups activation percentages, onset latency, articulations, etc.). That being said, we encourage tackling such issues by implementing an evidence based approach, with the patient at its core, in order to adapt the plan of treatment according to specific alterations that may be present.
