Spatiotemporal Gait Parameters as Predictors of Lower-Limb Overuse Injuries in Military Training

The study objective was to determine whether spatiotemporal gait parameters could predict lower-limb overuse injuries in cohort of combat soldiers during first year of military service. Newly recruited infantry soldiers walked on a treadmill at a 15 ∘ incline with a fixed speed of 1.67 m/sec while wearing a standard military vest with a 10 kg load. Stride time variability, stride length variability, step length asymmetry, and the duration of the loading response phase of the gait cycle were measured. Injury data on 76 soldiers who did not report musculoskeletal complaints at initial screening were collected one year after recruitment. Multiple logistic regression analyses were conducted to determine the predictive effect of the gait parameters on lower-limb injuries. Twenty-four soldiers (31.6%) had overuse injuries during the first year after recruitment. Duration of the loading response was a significant predictor of general lower-limb injury ( < 0.05), as well as of foot/ankle and knee injuries ( < 0.05, < 0.01, resp.). A cutoff value of less than 12.15% for loading response duration predicted knee injuries with 83% sensitivity and 67% specificity. This study demonstrates the utility of spatiotemporal gait evaluation, a simple screening tool before military training, which may help to identify individuals at risk of lower-limb overuse injuries

Validity of the Kinect for Gait Assessment: A Focused Review

Gait analysis may enhance clinical practice. However, its use is limited due to the need for expensive equipment which is not always available in clinical settings. Recent evidence suggests that Microsoft Kinect may provide a low cost gait analysis method. The purpose of this report is to critically evaluate the literature describing the concurrent validity of using the Kinect as a gait analysis instrument. An online search of PubMed, CINAHL, and ProQuest databases was performed. Included were studies in which walking was assessed with the Kinect and another gold standard device, and consisted of at least one numerical finding of spatiotemporal or kinematic measures. Our search identified 366 papers, from which 12 relevant studies were retrieved. The results demonstrate that the Kinect is valid only for some spatiotemporal gait parameters. Although the kinematic parameters measured by the Kinect followed the trend of the joint trajectories, they showed poor validity and large errors. In conclusion, the Kinect may have the potential to be used as a tool for measuring spatiotemporal aspects of gait, yet standardized methods should be established, and future examinations with both healthy subjects and clinical participants are required in order to integrate the Kinect as a clinical gait analysis tool

Attitudes and beliefs about musculoskeletal pain and its association with pain neuroscience knowledge among physiotherapy students in Israel

Abstract Background Physiotherapy has a vital role in helping patients manage and overcome musculoskeletal pain. Healthcare providers’ beliefs about pain are associated with the beliefs of their patients. This study evaluated the attitudes, beliefs and level of pain neuroscience knowledge among Israeli Bachelor-level physiotherapy students. Methods First-year (n = 29, before pain course), second-year (n = 28, immediately after pain course and before clinical placements), and fourth-year (n = 28, post-clinical placements) physiotherapy students completed the Health Care Providers’ Pain and Impairment Relationship Scale (HC-PAIRS, range 15–105, lower scores indicate a more positive attitude) to assess pain attitudes and beliefs. The Neurophysiology of Pain Questionnaire (NPQ, range 0–19, higher scores indicate more pain-related knowledge) was also completed to measure pain neuroscience knowledge. Two separate one-way ANOVAs with post hoc analyses were used to compare HC-PAIRS and NPQ results between the three groups of students. Pearson correlations were determined between HC-PAIRS and NPQ. Results HC-PAIRS scores of the first-year students were significantly higher than those of second- and fourth-year students (p = 0.011, p < 0.001, respectively), with no difference between second- and fourth-year students; indicating that first-year students had less-positive attitudes toward the ability of individuals with musculoskeletal pain to function. Similarly, NPQ scores showed that first-year students differed from second- and fourth-year students (p < 0.001, p < 0.001, respectively). The HC-PAIRS and NPQ correlation among the fourth-year students yielded a moderately negative association (r = − 0.462, p = 0.01), indicating that pain neuroscience knowledge was associated with less belief that chronic pain justifies disability. Conclusions A specific curriculum about pain during physiotherapy undergraduate education contributes to a more positive evidenced-based attitude to musculoskeletal pain and patient function. The association between pain neuroscience knowledge and positive attitudes and beliefs regarding pain were enhanced after clinical placements, demonstrating that learning improves when integrated into practice. Due to the impact of pain training and the expected benefits to patient care, health policy decision makers and educators should verify that the pain curriculum is current with the best research evidence. Future studies with larger samples that include students from other healthcare disciplines, including medicine are warranted

Cross-Cultural Adaptation, Reliability, and Validity of a Hebrew Version of the Physiotherapist Self-Efficacy Questionnaire Adjusted to Low Back Pain Treatment

Background: Clinician self-efficacy may be an important factor in the success of treatment for low back pain (LBP), which has unique clinical features and a high prevalence rate. Therefore, it is important to assess clinicians’ self-efficacy in this particular condition. The Physiotherapist Self-Efficacy (PSE) questionnaire was designed to measure self-efficacy of physiotherapy students. Objectives: To translate and trans-culturally adapt the PSE into Hebrew, to adjust the questionnaire to assess clinicians’ self-efficacy in the treatment of LBP, and to assess the construct validity and reliability of the PSE in the Hebrew version. Methods: After adjustment for LBP and cross-cultural adaptation, test–retest reliability was assessed with 140 physiotherapists. The analyses used included exploratory factor analysis for structural validity, Cronbach’s alpha for internal consistency, and intraclass correlation coefficients (ICC) for test–retest reliability. Results: Factor analysis revealed a unidimensional structure with an acceptable model fit. The PSE translated into Hebrew exhibited a very high internal consistency (α = 0.93) and excellent test–retest reliability (ICC = 0.94). The standard error of measurement (SEM) and minimal detectable change (MDC) were 1.75 and 4.85, respectively. Conclusions: The Hebrew-translated PSE showed adequate validity and excellent reliability, indicating its suitability to measure clinician self-efficacy in treating patients with LBP
