Differences in performance on the functional movement screen between chronic low back pain patients and healthy control subjects

Abstract

[Purpose] Differences in scores on the Functional Movement Screen between patients with chronic lower back pain and healthy control subjects were investigated. [Subjects and Methods] In all, 20 chronic lower back pain patients and 20 healthy control subjects were recruited. Chronic lower back pain patients and healthy controls performed the Functional Movement Screen (deep squat, hurdle step, inline lunge, shoulder mobility, active straight leg raise, trunk stability pushup, and rotary stability). The Mann-Whitney test was used to analyze differences in Functional Movement Screen scores between the two groups. [Results] Chronic lower back pain patients scored lower on the Functional Movement Screen total composite compared with healthy control subjects. Chronic lower back pain patients scored lower on Functional Movement Screen subtests including the deep squat, hurdle step, active straight leg raise, and rotary stability tests. [Conclusion] The deep squat, hurdle step, active straight leg raise, and rotary stability tasks of the Functional Movement Screen can be recommended as a functional assessment tools to identify functional deficits in chronic lower back pain patients.

Reliability and Validity of the Functional Movement Screen™ with a Modified Scoring System for Young Adults with Low Back Pain

“…The effect size of 0.80 was chosen based on the findings of a previous FMS™ study in an LBP population. 16 A convenience sample of the participants for the study was recruited from local communities. The eligible participants were young adults between 18 and 40 years of age.…”

“…15 Further, people with chronic pain demonstrated a lower FMS™ composite score as compared to healthy controls. 16 The reliability of the FMS™ has been established in different healthy populations. [17][18][19] The inter-rater reliability of FMS™ composite scores in these studies ranges from good (ICC = 0.76) to excellent (ICC = 0.98).…”

“…The inter-rater reliability and intra-rater reliability of the FMS™ test have been studied in individuals with LBP by Ko et al, 16 using its original scoring system, in which a zero score is assigned when there is presence of pain, regardless of the severity of the pain level. However, Ko et al did not describe whether or not their patient participants had LBP at the time of testing (baseline).…”

Measuring exercise adherence in patients with low back pain: development, validity, and reliability of the EXercise Adherence Scale (EXAS)

“…The first limitation is that the participants recruited for the reliability study were healthy subjects. Healthy subjects perform better during functional movement tasks when compared to patients with chronic LBP (Ko, Noh, Kang, and Oh, 2016). However, the reliability of the scoring system for the quality of exercise performance depends on the agreement between different ratings made by the same rater.…”

Sacroiliac Joint Hypermobility Biomechanics and What it Means for Health Care Providers and Patients

“…Successful management of lumbopelvic pain syndromes should include both anatomical and functional assessments of strength, endurance, flexibility, motor control, gait, and lumbopelvic kinematics. Various options are available for assessment, such as the Sorenson test, Prone Plank test, Functional Movement Screen, other movement control tests, and laboratory‐based gait analyses . The Lumbar Spine Instability Questionnaire is a 15‐item questionnaire that may be useful in assessing instability and guiding treatment approaches .…”
