The technology of self-report measures has advanced rapidly over the past few years. Recently, this technology was used to develop a performance-integrated self-report measure for use with patients with musculoskeletal impairments that may lead to work disability. Psychometric studies of the new measure in patient populations have been successful. A validation study of the measure with adults in good general health is necessary. The purpose of this study was to assess the concurrent validity of a new performance-integrated self-report measure, the multidimensional task ability profile (MTAP). A prospective validation study was conducted in which a self-report measure was administered online, and a physical performance test was administered at various clinics in North America. One hundred ninety-six (34% male) adult volunteers in good general health participated in this study. Self-report measure-MTAP. Physiologic measure-EPIC Lift Capacity test. The MTAP was administered online within 1 week of formal testing of lift capacity using a standardized lift capacity test, the EPIC Lift Capacity test. MTAP scores were compared with performance on the EPIC Lift Capacity test. Stepwise regression analysis was used to identify the strength of the relationship between the two measures and the relative explanation of lift capacity variance by the MTAP score, along with gender and age. The combination of MTAP score, gender, and age demonstrated a regression coefficient of R=0.82, which accounts for 67.3% of the variance in lift capacity. The MTAP displayed good concurrent validity compared with actual physical performance as assessed by the EPIC Lift Capacity test. Modern performance-integrated self-report measures, such as the MTAP, have the potential to provide information about functional capacity that is sufficiently useful to confirm status and help guide treatment algorithms.

Self-report measures of functional ability are commonly used in occupational rehabilitation to measure the current status of an individual and his or her progress in response to intervention. Most of these measures have been developed using classical test theory that does not provide calibration of the items. Methods of test development that originated in the field of Education have been applied recently to healthcare measures, providing item calibration and allowing proportional evaluation of total scores. The purpose of this article is to demonstrate the application of these methods in the revision of an existing self-report measure. The potential value of these methods to improve established measures is demonstrated.

The management of chronic low back pain (CLBP) has proven very challenging in North America, as evidenced by its mounting socioeconomic burden. Choosing among available nonsurgical therapies can be overwhelming for many stakeholders, including patients, health providers, policy makers, and third-party payers. Although all parties share a common goal and wish to use limited health-care resources to support interventions most likely to result in clinically meaningful improvements, there is often uncertainty about the most appropriate intervention for a particular patient. To help understand and evaluate the various commonly used nonsurgical approaches to CLBP, the North American Spine Society has sponsored this special focus issue of to The Spine Journal, titled Evidence-Informed Management of Chronic Low Back Pain Without Surgery. Articles in this supplement were contributed by leading spine practitioners and researchers, who were invited to summarize the best available evidence for a particular intervention and encouraged to make this information accessible to nonexperts. Each of the articles contains five sections (description, theory, evidence of efficacy, harms, and summary) with common subheadings to facilitate comparison across the 24 different interventions profiled in this special focus issue, blending narrative and systematic review methodology as deemed appropriate by the authors. It is hoped that articles in this special focus issue will be informative and aid in decision making for the many stakeholders evaluating nonsurgical interventions for CLBP.

There are basically two ways to change the structure in the painful spine, which include the use of strengthening exercises or repeat movements, which are guided by pain response. In this article, we take the position that strength training can only rationally be achieved by using exercise equipment that enables the knowledge of range, resistance, and number of repetitions on each exercise occasion. Without translating exercise into numbers, information that is available when using exercise equipment, progress is very difficult to define. The same is true with repeated movements, which can alter the location of pain. Such is the case with McKenzie testing, wherein centralization of the pain is the goal of the repeated movements. Adverse movements are defined those that cause peripheralization of the pain radiating into the extremities. Changing the internal status of the disc is the assumed function of repeated movements. The justification of these maneuvers is demonstrated by definable endpoints of improved function.

... However, these synthetic biomaterials do not mimic the architecture, porosity, and organic components of the natural bone and are not optimal in regard to biodegradation and host tissue integration or practical to implant or inject. Naturally occurring coral exoskeleton has a porous architecture that is similar to the human trabecular bone [4]. Since its main composition is calcium carbonate, a hydrothermal technique was developed to completely convert the calcium carbonate to be coralline hydroxyapatite (CHA) ceramics for clinical application [5][6][7][8]. ...

... It is also stated that greater scores of musculoskeletal discomfort and lower ranges of motion occur among people with low back pain. An earlier research (Mayer, Mooney, & Dagenais, 2012) has revealed that exercise offers many advantages for all those people with low back pain, and positive influences in them concerning stress, feelings and depressive, and anxiety disorder. Also exercise could to reduce the pain severity and scores of musculoskeletal discomfort (Sihawong et al., 2011). ...

... In Canada, LBP related medical costs range between 6 and 12 billion dollars each year, and continue to increase [4]. In addition, impairments in strength [5,6], flexibility [7,8], endurance [9], and obesity [10] are well documented in individuals with chronic LBP. Exercise therapy is currently the most widely used form of conservative treatment for chronic LBP, with recent reviews supporting its effectiveness [11,12]. ...

... Laminectomy and discectomy advocated by Mixter and Barr [1] in the surgical treatment of prolapsed lumbar disc were associated with high morbidity hence many minimally invasive techniques were devised to reduce approach-related morbidity. Techniques such as chymopapain, percutaneous lumbar nucleotomy, transforaminal and automated disc removal devices [2,[5][6][7][8], were minimally invasive but have not proven as effective as open lumbar disc surgery. The indications for these procedures have generally been limited to contained lumbar disc herniations. ...

... This strategy has been shown to effectively activate the lumbar extensors and other trunk extensor muscles [6,7]. Progressive resistance exercise training on these devices has been shown to result in large strength gains in healthy adults [4,5], and relieve symptoms and restore functional capacity in individuals with chronic low back pain [3,[8][9][10]. Existing back extension machines that stabilize the pelvis in the seated position and allow for gradual loading of lumbar extensors are intended for in-clinic use, which requires face-to-face interactions with a therapist or trainer. ...

... Maximum grip strength is observed in a standing posture, with the shoulder fixed forward at 45 degrees, the elbow at 90 degrees, and the wrist and forearm in a neutral position [57]. Assessing back extensor strength was done in the sitting position, allowing for improved joint stabilization, especially in the hip and knee [27,58]. This controlled position ensures reliable measurements of back extensor strength, making it a potentially reliable indicator of muscle strength. ...

Concerning socioeconomic transcendence, specific data to soft tissue injuries are scarce [27], but it has been determined that their economic impact defines them as the major medical problem of the industrialized society [28]. The engineering of tissues aims for the restoration, maintenance or improvement of tissue functions that are considered defective or that have been lost by different pathological conditions, either by the development of biological substitutes or by the reconstruction of tissues. ...
