translation and linguistic validation of the swedish version of Orthotics and prosthetics users survey
5th Regional Central European ISPO Conference Portorož Slovenien 19-21 sept 2008, 2008Co-Authors: Gustav Jarl, Liselotte M N HermanssonAbstract:There is an increasing need for outcome measures in the orthotic and prosthetic field and specifically a lack of outcome measures in Swedish. The Orthotics and Prosthetics Users’ Survey (OPUS) was developed in the USA for assessment of the outcome of orthotic and prosthetic interventions, and could potentially also be used for shoe insoles and orthopaedic shoes. The aims of this study were to translate OPUS into Swedish and test the translated version’s linguistic validity in a Swedish context. The Orthotic and Prosthetic Users’ Survey was translated into Swedish and back-translated into English, following a modified version of the World Health Organization guidelines. After revision of the Swedish version, 39 Swedish clients (12 men, 27 women) answered the OPUS questionnaires and were systematically debriefed afterwards. Most items were understood correctly by the respondents, but some words and expressions had to be changed to avoid misunderstandings or unintended interpretations. The resulting Swedish version of OPUS, OPUS-Swe, showed acceptable linguistic validity and has potential for use in both clinical practice and scientific settings. Nevertheless, before OPUS-Swe can be fully implemented, its psychometric properties need to be evaluated.

Running injuries and Orthotics : review article
International Sportmed Journal, 2006Co-Authors: Darren J Stefanyshyn, Blayne A. HettingaAbstract:lIgObjective:l/Ig To review the literature with respect to the influence of foot Orthotics on the treatment of running injuries and to discuss the biomechanical functioning of Orthotics during running. Data sources:l/Ig This paper was written based on peer-reviewed published literature. (Source: PubMed and SportDiscus. Search terms: orthotic, running, injury, and pertinent variants of each. Dates: all data inclusive to the end of 2005). lBRglIgConclusions:l/Ig The reported success rate of orthotic intervention in relieving running injury and pain varies from 25%-95% and is generally over 70%. However, randomised control studies that control for confounding factors are still required to fully evaluate the efficacy of orthotic use in running. Recent studies have challenged the previously accepted function of Orthotics in aligning the skeleton, suggesting that Orthotics result in minimal changes in skeletal movement. New concepts, such as reducing muscle activity, decreasing joint loading and increasing cushioning, have been proposed as potential functions of Orthotics in addressing running injuries. Some of the latest studies are starting to address these concepts but additional data are still required before definitive conclusions can be established.

Shoe inserts and Orthotics for sport and physical activities.
Medicine and science in sports and exercise, 1999Co-Authors: Benno Nigg, Matthew A. Nurse, Benno M Nigg, Darren J StefanyshynAbstract:The purposes of this paper were to discuss the perceived benefits of inserts and Orthotics for sport activities and to propose a new concept for inserts and Orthotics. There is evidence that inserts or Orthotics reduce or prevent movement-related injuries. However, there is limited knowledge about the specific functioning an orthotic or insert provides. The same orthotic or insert is often proposed for different problems. Changes in skeletal movement due to inserts or Orthotics seem to be small and not systematic. Based on the results of a study using bone pins, one may question the idea that a major function of Orthotics or inserts consists in aligning the skeleton. Impact cushioning with shoe inserts or Orthotics is typically below 10%. Such small reductions might not be important for injury reduction. It has been suggested that changes in material properties might produce adjustments in the muscular response of the locomotor system. The foot has various sensors to detect input signals with subject specific thresholds. Subjects with similar sensitivity threshold levels seem to respond in their movement pattern in a similar way. Comfort is an important variable. From a biomechanical point of view, comfort may be related to fit, additional stabilizing muscle work, fatigue, and damping of soft tissue vibrations. Based on the presented evidence, the concept of minimizing muscle work is proposed when using Orthotics or inserts. A force signal acts as an input variable on the shoe. The shoe sole acts as a first filter, the insert or orthotic as a second filter, the plantar surface of the foot as a third filter for the force input signal. The filtered information is transferred to the central nervous system that provides a subject specific dynamic response. The subject performs the movement for the task at hand. For a given movement task, the skeleton has a preferred path. If an intervention supports/counteracts the preferred movement path, muscle activity can/must be reduced/increased. Based on this concept, an optimal insert or orthotic would reduce muscle activity, feel comfortable, and should increase performance.

shoe Orthotics for the treatment of chronic low back pain a randomized controlled trial
Archives of Physical Medicine and Rehabilitation, 2017Co-Authors: Jerrilyn A Cambron, Jennifer M Dexheimer, Manuel A Duarte, Sally FreelsAbstract:Abstract Objectives To investigate the efficacy of shoe Orthotics with and without chiropractic treatment for chronic low back pain compared with no treatment. Design Randomized controlled trial. Setting Integrative medicine teaching clinic at a university. Participants Adult subjects (N=225) with symptomatic low back pain of ≥3 months were recruited from a volunteer sample. Interventions Subjects were randomized into 1 of 3 treatment groups (shoe orthotic, plus, and waitlist groups). The shoe orthotic group received custom-made shoe Orthotics. The plus group received custom-made Orthotics plus chiropractic manipulation, hot or cold packs, and manual soft tissue massage. The waitlist group received no care. Main Outcome Measures The primary outcome measures were change in perceived back pain (numerical pain rating scale) and functional health status (Oswestry Disability Index) after 6 weeks of study participation. Outcomes were also assessed after 12 weeks and then after an additional 3, 6, and 12 months. Results After 6 weeks, all 3 groups demonstrated significant within-group improvement in average back pain, but only the shoe orthotic and plus groups had significant within-group improvement in function. When compared with the waitlist group, the shoe orthotic group demonstrated significantly greater improvements in pain ( P P =.0068). The addition of chiropractic to Orthotics treatment demonstrated significantly greater improvements in function ( P =.0278) when compared with Orthotics alone, but no significant difference in pain ( P =.3431). Group differences at 12 weeks and later were not significant. Conclusions Six weeks of prescription shoe Orthotics significantly improved back pain and dysfunction compared with no treatment. The addition of chiropractic care led to higher improvements in function.

IROS - Wearable soft robotic device for post-stroke shoulder rehabilitation: Identifying misalignments
2012 IEEE RSJ International Conference on Intelligent Robots and Systems, 2012Co-Authors: Ignacio Galiana, Frank L. Hammond, Robert D Howe, Marko B PopovicAbstract:Stroke is the leading cause of long-term disability in the United States, affecting over 795,000 people annually. In order to regain motor function of the upper body, patients are usually treated by regular sessions with a dedicated physical therapist. A cost-effective wearable upper body Orthotics system that can be used at home to empower both the patients and physical therapists is described. The system is composed of a thin, compliant, lightweight, cost-effective soft orthotic device with an integrated cable actuation system that is worn over the upper body, an embedded limb position sensing system, an electric actuator package and controller. The proposed device is robust to misalignments that may occur during actuation of the compliant brace or when putting on the system. Through simulations and experimental evaluation, it was demonstrated i) that the soft orthotic cable-driven shoulder brace can be successfully actuated without the production of off-axis torques in the presence of misalignments and ii) that the proposed model can identify linear and angular misalignments online.
