Immediate and Short-Term Effects of Kinesiotaping on Muscular Activity Reynard et al. BMC Musculoskeletal Disorders (2018) 19:305 https://doi.org/10.1186/s12891-018-2169-5 RESEARCH ARTICLE Open Access Immediate and short-term effects of kinesiotaping on muscular activity, mobility, strength and pain after rotator cuff surgery: a crossover clinical trial Fabienne Reynard1* , Philippe Vuistiner2, Bertrand Léger2 and Michel Konzelmann3 Abstract Background: Kinesiotape (KT) is widely used in musculoskeletal rehabilitation as an adjuvant to treatment, but minimal evidence supports its use. The aim of this study is to determine the immediate and short-term effects of shoulder KT on muscular activity, mobility, strength and pain after rotator cuff surgery. Methods: Thirty-nine subjects who underwent shoulder rotator cuff surgery were tested 6 and 12 weeks post-surgery, without tape, with KT and with a sham tape (ST). KT and ST were applied in a randomized order. For each condition, the muscular activity of the upper trapezius, three parts of the deltoid and the infraspinatus were measured during shoulder flexion, and range of motion (ROM) and pain intensity were assessed. At 12 weeks, the isometric strength at 90° of shoulder flexion, related muscular activity and pain intensity were also measured. Subjects maintained the last tape that was applied for three days and recorded the pain intensity at waking up and during the day. Results: Modifications in muscle activity were observed with KT and with ST. Major changes in terms of decreased recruitment of the upper trapezius were observed with KT (P < 0.001). KT and ST also increased flexion ROM at 6 weeks (P = 0.004), but the differences with the no tape condition were insufficient to be clinically important. No other differences between conditions were found. Conclusions: Shoulder taping has the potential to decrease over-activity of the upper trapezius, but no clinical benefits of KT on ROM, strength or pain were noted in a population of subjects who underwent rotator cuff surgery. Trial registration: The study was retrospectively registered on ClinicalTrials.gov PRS (NCT03379636)on21stDecember 2017.

    Current Reviews in Musculoskeletal Medicine (2018) 11:113–121 https://doi.org/10.1007/s12178-018-9465-4 ROTATOR CUFF REPAIR (M TAO AND M TEUSINK, SECTION EDITORS) Partial and Full-Thickness RCT: Modern Repair Techniques Amit Nathani1 & Kevin Smith1 & Tim Wang1 Published online: 22 January 2018 # Springer Science+Business Media, LLC, part of Springer Nature 2018 Abstract Purpose of Review The purpose of this article is to review the recent literature concerning modern repair techniques related to partial- and full-thickness rotator cuff tears. Recent Findings The understanding of rotator cuff pathology and healing continues to evolve, beginning with emerging descrip- tions of the anatomic footprint and natural history of rotator cuff tears. Significant controversy remains in treatment indications for partial-thickness rotator cuff lesions as well as optimal surgical repair techniques for both partial- and full-thickness tears. Techniques such as margin convergence and reduction of the so-called “comma” tissue have improved the ability to anatomically reduce large and retracted tears. Repair strength and contact pressures are improved with double-row repairs and transosseus- equivalent techniques compared to traditional single-row repairs. Future work is directed towards obtaining reliable radiographic healing and demonstrating clinical superiority and cost-effectiveness of a single technique. Summary Much recent work regarding rotator cuff anatomy and pathology has been reported. Newer techniques improve repair strength. Despite these advances, significant questions remain concerning surgical indications and clinical outcomes. Keywords Rotator cuff . Repair . Anatomy . Technique . Review . Outcomes Introduction muscle degeneration and atrophy, which may preclude suc- cessful surgical repair [4•, 5, 6].

  • Musculoskeletal Conditions
    TUE Physician Guidelines Medical Information to Support the Decisions of TUE Committees Musculoskeletal Conditions MUSCULOSKELETAL CONDITIONS 1. Medical Condition Musculoskeletal conditions including those arising from injuries are common in sport. However, athletes are also susceptible to arthropathies with a familial or degenerative aetiology such as osteoarthritis, rheumatological or autoimmune diseases. In the setting of sport we traditionally classify injury according to a mechanism of acute macrotrauma or repetitive overuse ranging from minor injuries to muscle, tendon and other “soft tissues” to more serious fractures, dislocations and spinal cord trauma. Consequently the use of pharmacological agents and hence the need for TUE will vary. The management of musculoskeletal conditions requires some understanding of the inflammatory response and the biochemistry of pain production. Potent anti-inflammatory agents, powerful analgesics and even so called “disease-modifying agents” are amongst the agents used to treat musculoskeletal conditions This is especially so for conditions such as rheumatoid arthritis, systemic lupus erythematosus (SLE) and ankylosing spondylitis which may require long-term or intermittent administration of medications. Relevant to the TUE process, there are two classes of prohibited substances commonly used in the management of musculoskeletal conditions. These are glucocorticoids (GCs) and narcotic analgesics, both of which are only prohibited “in-competition”. Therefore a TUE is required only when these substances are necessary during a defined in-competition period and, in the case of GCs, if they are administered via oral, rectal, intramuscular or intravenous routes. GCs are commonly used to manage musculoskeletal injuries and conditions because of their potency as anti-inflammatory agents. However, in some instances their use in competitive sport has become excessive and inappropriate with little regard for potential side effects.

Bauer University of Wisconsin-Milwaukee, 2012 Under the Supervision of Professor Stephen C. Cobb Plantar fasciitis is a common lower extremity injury caused by mechanical overload that affects 10% of all runners. Despite its commonality, research results investigating the etiology of the condition and the most efficacious treatment have been equivocal. A potential limitation of previous research assessing the mechanical changes associated with plantar fasciitis may be the modeling of the foot as a single segment. To date no study has investigated running kinematics in individuals with plantar fasciitis using a multi-segment foot model.

WHEN A MUSCLE, TENDON, NERVE OR JOINT IS STRESSED AND TRAUMATIZED ON A REPEATED BASIS FOR DAYS, MONTHS OR YEARS, THOSE BODY TISSUES EVENTUALLY BECOME DAMAGED. This leads to a work related musculoskeletal disorder. Work related musculoskeletal disorders (WMSDs) are sometimes called repetitive strain injuries (RSIs), cumulative trauma disorders and overuse injuries. When a WMSD develops, a worker experiences: 1. Swelling, as some tissues become irritated 2. Pain 3. Stiffness and loss of range of motion of surrounding joints 4. Inability to work and function at home Besides the most common upper extremity disorders, WMSDs may also affect the low back, knees, ankles and feet. HOW DO YOU TREAT WMSDs? Ergonomics should be a priority in the workplace, so WMSDs are prevented instead of treated. If you think you have signs and symptoms of a repetitive strain injury, see your doctor. Make sure your doctor has a description of your job and understands how your job affects your body. Treatment may involve a combination of approaches such as: Job modifications Services of health professionals, such as physiotherapists or massage therapists Exercise program Use of medication
