Purpose The purpose of this study was to develop a novel instrument for assessing headache-related disability focusing solely on important activities of daily living. Methods Part 1: A literature search was conducted in PubMed and Google Scholar, supplemented by hand searches in bibliographies to retrieve the original article for any instrument for the assessment of headache-related disability. Each instrument was evaluated for item categories, specific item content, measurement scale format for each item, and instructions to users. Together, these features constituted the construct validity of these instruments. Qualitative evaluations of these results were summarized with respect to the adequacy of each component. Psychometric features such as reliability and validity were not assessed. Part 2: An existing instrument for assessing self-rated disability, the Neck Disability Index, was modified for content and format and subjected to 2 rounds of clinician and patient review. Item contents and formats received final consensus, resulting in a 9-item instrument: the Headache Activities of Daily Living Index (HADLI). This instrument was tested in a sample of headache patients. Cronbach α and individual item correlations were obtained. Principal Components Analysis was performed. Results Part 1: The search identified 6 reports on 5 preexisting instruments for self-rating of headache-related disability. Problems in content were found in all instruments, especially relating to the lack of items for specific activities of daily living. Problems were noted in most of the instruments for scaling and instructions with respect to the effect of headache on activities of daily living. Part 2: The authors first identified suitable items from an existing instrument for self-rating of disability. These were supplemented by items drawn from the literature. A panel of 3 clinicians and 2 laypersons evaluated these items. Two more focus groups of 7 headache sufferers each reviewed the new instrument. After this, a 9-item instrument for assessing activities of daily living in headache sufferers, the HADLI, was finalized. After this, 53 participants were recruited to study the face validity of the instrument. The sample consisted of 41 women and 12 men with a mean age of 37.3 (12) years; mean duration of headaches was 7.4 (8.3) years; mean frequency of headaches per week was 3.4 (2.4); and the intensity was 6 (2.4). The mean HADLI score was 26.2 (13.4), or 52%. There were no floor or ceiling effects for total score. The total Index Cronbach α was 0.96. The Principal Components Analysis identified one component which accounted for 75% of the variance. Conclusions The HADLI was created using theory and empirical-based methods. Face validity was assessed by focus group input and by first-level psychometrics. The HADLI has good face validity and is suitable for further reliability and validity testing. © 2015 National University of Health Sciences.

Despite the findings that peak anterior shear load is highly correlated with low-back pain reporting, very little research has been conducted to determine how vertebral shear injury potential is influenced. The current study quantified the combined effects of vertebral joint compression and flexion/extension postural deviation from neutral on ultimate shear failure. Ninety-six porcine cervical specimens (48C3-C4, 48C5-C6) were tested. Each specimen was randomly assigned to one of twelve combinations of compressive force (15%, 30%, 45%, or 60% of predicted compressive failure force) and flexion/extension postural deviation (extended, neutral, or flexed). Vertebral joint shear failure was induced by applying posterior shear displacement of the caudal vertebra at a constant rate of 0.15. mm/s. Throughout shear failure tests, vertebral joint kinematics were measured using an optoelectronic camera and a series of infrared light emitting diodes while shear force was measured from load cells rigidly interfaced in series with linear actuators that applied the shear displacement. Measurements of shear stiffness, ultimate force, displacement, and energy stored were made from the force-displacement data. Compressive force and postural deviation demonstrated main effects without a statistically significant interaction for any of the measurements. Shear failure force increased by 11.1% for each 15% increment in compressive force (p<0.05). Postural deviation from neutral impacted ultimate shear failure force by a 12.8% increase with extension (p<0.05) and a 13.2% decrease with flexion (p<0.05). Displacement at ultimate failure was not significantly altered by either compressive force or postural deviation. These results demonstrate that shear failure force may be governed by changes in facet articulation, either by postural deviation or by reducing vertebral joint height through compression that alter the moment arm length between the center of facet contact pressure and the pars interarticularis location. However, objective evidence of this alteration currently does not exist. Both compression and flexion/extension postural deviation should be equally considered while assessing shear injury potential. © 2011 Elsevier Ltd.

Background: The biomechanical relationship between the hip and low back is well described and impairment of hip range of motion is thought to affect lumbar spine function, possibly leading to increased loading and subsequent symptoms. However therapy for low back pain (LBP) patients is commonly directed solely to the low back area overlooking possible hip impairment. Case description: A 56-year-old male recreational golfer presented with a chronic golf-related low back complaint. Previous conservative therapy targeting the spine did not result in complete symptom relief. A working diagnosis of L4-S1 facet joint irritation and lower lumbar segmental instability secondary to bilateral hip ROM impairment was established. A trial of therapy strictly addressing the hip ROM impairments was initiated and following 2 treatment sessions, a complete resolution of symptoms was achieved and maintained at a 2-month follow-up. Discussion: This case demonstrated a complete and rapid relief of un-resolving low back pain with a management strategy focused on hip ROM impairments. Clinicians should remember to look beyond the local area of complaint and appreciate the interdependent nature of the musculoskeletal system. © 2013 Elsevier Ltd.

Objectives: To investigate the effects of topical agents for the treatment of Myofascial Pain Syndrome (MPS) and Myofascial Trigger Point (MTRP).Methods: Subjects with an identifiable trigger point in the trapezius muscle, age 18-80 were recruited for a single-session randomized, placebo-blinded clinical study. Baseline measurements of trapezius muscle pressure pain threshold (PPT: by pressure algometer) along with right and left cervical lateral flexion (rangiometer) were obtained by a blinded examiner. An assessor blinded to the outcomes assessments applied one of 6 topical formulations which had been placed in identical plastic containers. Five of these topicals were proposed active formulations; the control group was given a non-active formulation (PLA). Five minutes after the application of the formula the outcome measures were re-tested. Data were analyzed with a 5-way ANOVA and Holms-adjusted t-tests with an alpha level of 0.05.Results: 120 subjects were entered into the study (63 females; ages 16-82); 20 subjects randomly allocated into each group. The pre- and post-treatment results for pressure threshold did show significant intra-group increases for the Ben-Gay Ultra Strength Muscle Pain Ointment (BG), the Professional Therapy MuscleCare Roll-on (PTMC roll-on) and Motion Medicine Cream (MM) with an increased threshold of 0.5 kg/cm2(+/-0.15), 0.72 kg/cm2(+/-0.17) and 0.47 Kg/cm2(+/-0.19) respectively. With respect to the inter-group comparisons, PTMC roll-on showed significant increases in pressure threshold compared with Placebo (PLA) (p = 0.002) and Icy Hot Extra Strength Cream (IH) (p = 0.006). In addition, BG demonstrated significant increases in pressure threshold compared with PLA (p = 0.0003).Conclusions: With regards to pressure threshold, PTMC roll-on, BG and MM showed significant increases in pain threshold tolerance after a short-term application on a trigger points located in the trapezius muscle. PTMC roll-on and BG were both shown to be superior vs placebo while PTMC was also shown to be superior to IH in patients with trigger points located in the trapezius muscle on a single application.CMCC Research Ethics Board Approval # 1012X01, 2011. © 2012 Avrahami et al; licensee BioMed Central Ltd.

Background: The mechanisms subserving deep spinal pain have not been studied as well as those related to the skin and to deep pain in peripheral limb structures. The clinical phenomenology of deep spinal pain presents unique features which call for investigations which can explain these at a mechanistic level.Methods: Targeted searches of the literature were conducted and the relevant materials reviewed for applicability to the thesis that deep spinal pain is distinctive from deep pain in the peripheral limb structures. Topics related to the neuroanatomy and neurophysiology of deep spinal pain were organized in a hierarchical format for content review.Results: Since the 1980's the innervation characteristics of the spinal joints and deep muscles have been elucidated. Afferent connections subserving pain have been identified in a distinctive somatotopic organization within the spinal cord whereby afferents from deep spinal tissues terminate primarily in the lateral dorsal horn while those from deep peripheral tissues terminate primarily in the medial dorsal horn. Mechanisms underlying the clinical phenomena of referred pain from the spine, poor localization of spinal pain and chronicity of spine pain have emerged from the literature and are reviewed here, especially emphasizing the somatotopic organization and hyperconvergence of dorsal horn " low back (spinal) neurons" . Taken together, these findings provide preliminary support for the hypothesis that deep spine pain is different from deep pain arising from peripheral limb structures.Conclusions: This thesis addressed the question " what is different about spine pain?" Neuroanatomic and neurophysiologic findings from studies in the last twenty years provide preliminary support for the thesis that deep spine pain is different from deep pain arising from peripheral limb structures. © 2012 Vernon; lisencee BioMed Central Ltd.

Biomedical language, also known as biomedical English, is sufficiently different from general English to warrant treatment as a distinct language. Biomedical language has its own conventions of grammar, phraseology and discourse, as well as a lexicon which is complex and esoteric. Furthermore, each sub-discipline, such as integrative medicine, has a unique vocabulary which must be mastered in order to achieve fluency. In this article, the vocabulary specific to acupuncture is identified, and strategies are introduced to master the use of that vocabulary. © 2013 Brian Stephen Budgell.

The purpose of this study was to determine the rate and type of injury in elite Canadian Taekwondo athletes, before and during competition and to investigate the relationship between past injuries, injuries during competition and success. This retrospective case-series study incorporated Taekwondo injuries sustained by 75 male and female elite Canadian Taekwondo athletes over 10 years and its relationship to athletes' success by means of gaining medals during competition. A logistic regression model (using the Generalised Estimating Equations (GEE) method) was used to investigate the relationship between injuries and success. Injury rate was associated with performance after holding variables constant (Odds Ratio (OR)1/40.124, P1/40.039). Moreover, with each additional injury per match, competitors were 88% (1-0.124) less likely to win a medal. Although not statistically significant, additional injuries prior to competition were associated with a 30% increase in medal prevalence (OR1/41.299, P1/40.203). When comparing athletes (gender, tournament difficulty, injury variables), a competitor who is one year older is 10% less likely to medal (OR1/40.897, P1/40.068). When an additional injury occurred during competition, the athlete was 88% less likely to win a medal. Prevention, correct diagnosis, and immediate therapeutic intervention by qualified health care providers are important. © 2012 Taylor & Francis.
