Therapeutic effects of acupuncture plus fire needle versus acupuncture alone in lateral epicondylitis: A randomized case-control pilot study.

BACKGROUND: The aim of this study was to compare the short-term and intermediate-term efficacy of acupuncture plus fire needle therapy with that of acupuncture alone in the treatment of lateral epicondylitis (LE). METHODS: Thirty-eight patients with LE who had persisted for at least 2 months were enrolled in this prospective, assessor-blinded, randomized controlled pilot trial. Twenty-one patients were randomized to the acupuncture plus fire needle group and 17 to the acupuncture-only group. The primary outcome was the visual analog scale pain score for the previous 24 hours and the secondary outcomes were the maximum grip strength, Patient-rated Forearm Evaluation Questionnaire score, and Medical Outcomes Study 36-Item Short-form Health Survey score. The values at baseline (pretreatment), at the end of treatment, and at 3 months after treatment were used to assess the short-term and intermediate-term effects of treatment. The data were analyzed using the Chi-square test and t test. RESULTS: Within-group analyses showed better results for acupuncture plus fire needle therapy in the short term and intermediate term. Differences in the severity of pain and secondary outcomes were significant in the intermediate term in the acupuncture group. At the end of treatment, none of the differences in outcome scores were significant, except for maximum grip strength in the affected hand in the acupuncture group. No significant between-group differences in short-term or intermediate-term outcomes were observed. CONCLUSION: Acupuncture plus fire needle therapy was effective in the short term in patients seeking improvement of LE. Twelve treatments were effective for relieving pain and improving disability in the intermediate term in patients with chronic LE in both study groups. The findings of the pilot study confirm the feasibility of proceeding to a larger randomized controlled study of the longer-term effects of acupuncture plus fire needle therapy in patients with LE.

Effective Timing of Curcumin Ingestion to Attenuate Eccentric Exercise-Induced Muscle Soreness in Men.

Curcumin is known to have potent anti-inflammatory effects. We have reported that acute curcumin ingestion attenuates eccentric exercise-induced muscle damage. This study aimed to examine the effect of curcumin ingestion timing (before or after exercise) on the changes in muscle damage markers after eccentric exercise. In this randomized, single-blind, parallel design study, 24 healthy young men performed 30 maximal isokinetic (120º/s) eccentric contractions of the elbow flexors using an isokinetic dynamometer. Subjects were randomly assigned to ingest 180 mg/d of oral curcumin either 7 d before (PRE) or 4 d after exercise (POST) or 180 mg/d of oral placebo 4 d after exercise (CON). The maximal voluntary contraction (MVC) torque of the elbow flexors, elbow joint range of motion (ROM), muscle soreness, and serum creatine kinase (CK) activity were measured before, immediately after, and 1-4 d after exercise. Changes in these variables were compared over time. In the POST group, ROM were higher at 3-4 d and muscle soreness was lower at 3 d after exercise compared with the CON group (p<0.05). However, in the PRE group, there were no significant differences compared with the CON group in changes in ROM and muscle soreness. Meanwhile, there were no significant differences among the groups in terms of changes in MVC torque and serum CK activity. Our results suggest that curcumin ingestion after exercise had a more beneficial effect in attenuating muscle soreness.

Therapeutic heat and cold around the elbow on the response of median neurodynamic test 1.

OBJECTIVE: To compare the effects of the application of therapeutic heat and cold on the mechanical response of the median nerve neurodynamic testing. DESIGN: Single-blinded randomized crossover trial. METHODOLOGY: 56 asymptomatic university students (mean age = 21.82 ±â€¯1.64 years) of either gender with a limited elbow extension range of motion during a Median Neurodynamic Test 1 were recruited. Each subject was administered 3 testing conditions on separate days with a 24-hr washout period. The interventions included 1) therapeutic moist heat around the elbow, 2) therapeutic cold around the elbow and 3) no thermal agent as a controlled condition. Outcome measure of elbow extension range of motion at the onset of pain and submaximal pain were recorded before the intervention, immediately after the removal of the thermal agents (20th min) and at 2 subsequent readings of 30 min and 1 hour after the removal of the thermal agent. RESULTS: There was a significant effect of using a thermal agent with time on the elbow range of motion at the onset of pain [F(2,165) = 3.622, p = 0.029] and submaximal pain[F(2,165) = 3.841, p = 0.023] at the 20th min. A posthoc comparison indicated that at the 20th min the mean elbow range at the onset of pain and submaximal pain for the therapeutic heat condition (mean = 33.5, S.D = 13.37 and mean = 16.80, S.D = 12.99 respectively) was significantly different than the no thermal agent condition (mean = 40.17, S.D = 12.34 and mean = 23.4, S.D = 13.82 respectively). However, therapeutic cold condition did not significantly differ from both the other conditions. CONCLUSION: Therapeutic heat causes an immediate increase in elbow extension range of motion during a Median Neurodynamic Test1 and testing post the application of thermal agents can alter the test response.

The Effects of Needling Therapies on Muscle Force Production: A Systematic Review and Meta-analysis.

BACKGROUND: Needling has been shown to decrease pain in the short term; however, its effects on muscle force production are unclear. OBJECTIVE: To evaluate the evidence regarding the comparative effects of needling on muscle force production. METHODS: In this systematic review, an electronic search was performed using key words related to needling. Methodological quality of articles was appraised and effect sizes were calculated. The strength of evidence was determined, and meta-analysis was performed when similar methods were used in studies for similar conditions. RESULTS: Twenty-one studies were included in this review, of which 9 were deemed to be of high quality (greater than 6/10 on the Physiotherapy Evidence Database [PEDro] scale), 11 of fair quality (5 to 6/10), and 1 of poor quality (less than 5/10). Three meta-analyses were performed. There was moderate strength of evidence and medium effect sizes for needling therapy to enhance force production in those with neck pain, and very low strength of evidence of no effect for individuals with nonspecific and postoperative shoulder pain and those with lateral epicondylalgia. Other studies not included in the 3 meta-analyses demonstrated no significant effect of needling on force production. These studies included individuals with carpal tunnel syndrome, knee osteoarthritis, ankle sprains, knee arthroscopy, or delayed-onset muscle soreness. CONCLUSION: The majority of studies suggest no effect of dry needling on force production. High-quality studies with adequate power that control for the placebo effect and follow accepted reporting standards could make valuable contributions to the literature. This study was registered with the International Prospective Register of Systematic Reviews (PROSPERO, CRD42017080318). LEVEL OF EVIDENCE: Therapy, level 1a. J Orthop Sports Phys Ther 2019;49(3):154-170. Epub 30 Nov 2018. doi:10.2519/jospt.2019.8270.

Manipulation Under Anesthesia as a Treatment of Posttraumatic Elbow Stiffness.

OBJECTIVES: Evaluate the safety and efficacy of manipulation under anesthesia (MUA) for posttraumatic elbow stiffness. DESIGN: Retrospective, case series. SETTING: Single institution; level 1 trauma center. PATIENTS/PARTICIPANTS: Chart review of 45 patients over a 10-year period treated with MUA for posttraumatic elbow stiffness after elbow injuries treated both operatively and nonoperatively. INTERVENTION: None. MAIN OUTCOME MEASURES: Change in total flexion arc pre- to postmanipulation; time to manipulation; complications. RESULTS: Average time from most recent surgical procedure or date of injury to MUA was 115 days. Average premanipulation flexion arc was 57.9 degrees; average flexion arc at the final follow-up was 83.7 degrees. The improvement in elbow flexion arc of motion was statistically significant (P < 0.001). Post hoc analysis of the data revealed 2 distinct groups: 28 patients who underwent MUA within 3 months of their most recent surgical procedure (early manipulation), and 17 patients who underwent MUA after 3 months (late manipulation). Average improvement in elbow flexion arc in the early MUA group was 38.3 degrees (P < 0.001); improvement in the late MUA group was 3.1 degree. Comparison of improvement between the early and late MUA groups found a significant difference (P < 0.001) in mean flexion arc improvement from premanipulation to postmanipulation, favoring the early group. One patient had a complication directly attributable to MUA. Nineteen patients required additional procedures on the injured extremity after MUA. CONCLUSIONS: MUA is a safe and effective adjunct to improving motion in posttraumatic elbow stiffness when used within 3 months from the original injury or time of surgical fixation. After 3 months, MUA does not reliably increase elbow motion. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Conservative treatment in displaced fractures of the humeral capitellum: a reduction technique under local anaesthesia.

We report the case of a 46-year-old woman who struck her right elbow on the ground after a fall on ice. Radiography showed a right humeral capitellar fracture, and CT further confirmed a Dubberley type 1A fracture. Closed reduction was performed under local anaesthesia, and an anatomical position was obtained. After the reduction, her right elbow was casted for 18 days. Three months after the injury, bone union was achieved without displacement, and the active range of motion of her right elbow recovered similar to the unaffected side. At 1 year postinjury, the Grantham score was excellent, and she obtained a two-point score on the Disabilities of the Arm, Shoulder and Hand (DASH) Questionnaire. Although surgical treatment is recommended for a displaced humeral capitellar fracture, a Dubberley type 1A (no posterior column fracture of a distal humerus) can be effectively treated by early closed reduction.

Hypoalgesic effects of three different manual therapy techniques on cervical spine and psychological interaction: A randomized clinical trial.

OBJECTIVE: The purpose of this study was to evaluate the extent to which psychological factors interact with a particular manual therapy (MT) technique to induce hypoalgesia in healthy subjects. METHODS: Seventy-five healthy volunteers (36 female, 39 males), were recruited in this double-blind, controlled and parallel study. Subjects were randomly assigned to receive: High velocity low amplitude technique (HVLA), joint mobilization, or Cervical Lateral glide mobilization (CLGM). Pressure pain threshold (PPT) over C7 unilaterally, trapezius muscle and lateral epicondyle bilaterally, were measured prior to single technique MT was applied and immediately after to applied MT. Pain catastrophizing, depression, anxiety and kinesiophobia were evaluated before treatment. RESULTS: The results indicate that hypoalgesia was observed in all groups after treatment in the neck and elbow region (P < 0.05), but mobilization induces more hypoalgesic effects. Catastrophizing interacted with change over time in PPT, for changes in C7 and in manipulation group. CONCLUSIONS: All the MT techniques studied produced local and segmental hypoalgesic effects, supporting the results of previous studies studying the individual interventions. Interaction between catastrophizing and HVLA technique suggest that whether catastrophizing level is low or medium, the chance of success is high, but high levels of catastrophizing may result in poor outcome after HVLA intervention.

Development of network-based multichannel neuromuscular electrical stimulation system for stroke rehabilitation.

Neuromuscular electrical stimulation (NMES) is a promising assistive technology for stroke rehabilitation. Here we present the design and development of a multimuscle stimulation system as an emerging therapy for people with paretic stroke. A network-based multichannel NMES system was integrated based on dual bus architecture of communication and an H-bridge current regulator with a power booster. The structure of the system was a body area network embedded with multiple stimulators and a communication protocol of controlled area network to transmit muscle stimulation parameter information to individual stimulators. A graphical user interface was designed to allow clinicians to specify temporal patterns and muscle stimulation parameters. We completed and tested a prototype of the hardware and communication software modules of the multichannel NMES system. The prototype system was first verified in nondisabled subjects for safety, and then tested in subjects with stroke for feasibility with assisting multijoint movements. Results showed that synergistic stimulation of multiple muscles in subjects with stroke improved performance of multijoint movements with more natural velocity profiles at elbow and shoulder and reduced acromion excursion due to compensatory trunk rotation. The network-based NMES system may provide an innovative solution that allows more physiological activation of multiple muscles in multijoint task training for patients with stroke.

Implementation of EMG- and Force-Based Control Interfaces in Active Elbow Supports for Men With Duchenne Muscular Dystrophy: A Feasibility Study.

While there is an extensive number of studies on the development and evaluation of electromyography (EMG)- and force-based control interfaces for assistive devices, no studies have focused on testing these control strategies for the specific case of adults with Duchenne muscular dystrophy (DMD). This paper presents a feasibility study on the use of EMG and force as control interfaces for the operation of active arm supports for men with DMD. We have built an experimental active elbow support, with a threefold objective: 1) to investigate whether adult men with DMD could use EMG- and force-based control interfaces; 2) to evaluate their performance during a discrete position-tracking task; and 3) to examine users' acceptance of the control methods. The system was tested in three adults with DMD (21-22 years). Although none of the three participants had performed any voluntary movements with their arms for the past 3-5 years, all of them were 100% successful in performing the series of tracking tasks using both control interfaces (mean task completion time EMG: [Formula: see text] , force: [Formula: see text] ). While movements with the force-based control were considerably smoother in Subject 3 and faster in Subject 1, EMG based-control was perceived as less fatiguing by all three subjects. Both EMG- and force-based interfaces are feasible solutions for the control of active elbow supports in adults with DMD and should be considered for further investigations on multi-DOF control.

Correction of Cubitus Varus After Pediatric Supracondylar Elbow Fracture: Alternative Method Using the Taylor Spatial Frame.

BACKGROUND: Cubitus varus is a well-reported complication of supracondylar fracture of the humerus potentially resulting in cosmetic problems, impaired function, and malpractice claims. Traditional methods of correcting malunited distal humeral fractures involve complex osteotomies that have a high complication rate, require a large exposure, and challenging fixation. We present a technique of gradual correction using a percutaneous transverse osteotomy and 3 dimensional correction with a Taylor Spatial Frame. METHODS: This was a retrospective, IRB-approved study of 12 patients between 2006 and 2010, with cubitus varus after a malunited pediatric supracondylar fracture. The average age at initial injury was 5+8 years. The average age of the patients at surgery was 8+8 years. We measured technical (radiographic parameters and complications), functional (clinical carrying angle, range of motion, QuickDash), and satisfaction domain (questionnaire) outcomes at a minimum follow-up of 6 months. RESULTS: The osteotomy healed in all patients by 10 weeks after the index surgery. The mean external fixator time was 10 weeks. The average preoperative and postoperative humeroulnar angles for the affected elbow were 23 degrees varus and 5.8 degrees valgus, respectively. This was statistically significant (P<0.001). The mean preoperative and postoperative carrying angles were 22 degrees of varus and 5.8 degrees of valgus. This was statistically significant (P<0.001). The results of the QuickDash assessment showed that patients were doing very well with regard to the use of their upper extremity. The mean symptom/disability score was 0.80. No major complications or neurovascular complications were encountered. Overall satisfaction with the procedure was high. CONCLUSIONS: The Taylor Spatial Frame as used in this case series provides the experienced surgeon another safe, accurate, and reliable method to correct cubitus varus after pediatric supracondylar fracture. We used in 7 of our 12 cases, a previously unreported pattern of distal humeral pin fixation that allows for a very distal metaphyseal osteotomy, close to the deformity apex. This is a biplanar delta configuration that straddles the olecranon fossa and is appropriate for both children and adults. LEVEL OF EVIDENCE: Level IV.

Research on musculoskeletal model of elbow joint for evaluating the feasibility of FES.

Tremor usually occurs in a patient's upper limb with a roughly sinusoidal profile. Understanding the inner mechanism of the involuntary movement is fundamental to improving tremor suppression treatments. Therefore, the musculoskeletal model of the elbow joint was developed in this study. Initially, healthy subjects were selected to simulate tremor and the tremulous data was collected with the purpose of sparing patients from fatigue. With the recorded joint angle and surface EMG (sEMG), the model was calibrated to subjects by optimization approach. The activation derived from the electric pulse was employed to drive the tuned model and the model's output was compared with the angle predicted by the EMG-driven musculoskeletal model. The results demonstrated that the performance of the calibrated model was improved by a smaller normalized root mean square error and a higher coefficient of determination compared with the no-tuned model. There was no significant difference between the angles estimated by the tuned model activated by the electric pulse and muscle excitation. It indicates that neural activation could be replaced by the electric pulse to excite the limbs for desired angle. Therefore, the study presents a good way to evaluate the feasibility of Functional Electric Stimulation to suppress tremor.

Outcomes of arthroscopic treatment of osteochondritis dissecans of the capitellum and description of the technique.

HYPOTHESIS: We hypothesize that a technique for all-arthroscopic fixation of capitellum osteochondritis dissecans (OCD) lesions using suture fixation and autogenous iliac crest bone grafting offers a successful alternative to open internal fixation techniques as shown by 2-year validated patient-reported outcomes. METHODS: Our technique uses arthroscopic all-inside suture fixation with iliac crest autogenous bone grafting. The procedure was performed on 4 elite-level, adolescent athletes presenting with 5 unstable capitellum OCD lesions resulting in elbow pain, limited range of motion, and decreased ability to play. Magnetic resonance imaging showed an unstable OCD lesion, which was correlated with arthroscopy. Postoperatively, patients were evaluated by the short version of the Disabilities of the Arm, Shoulder and Hand questionnaire; Oxford Elbow and Mayo Elbow scores; visual analog scale; postoperative range of motion; and return to play. RESULTS: Three female patients and one male patient aged 13 to 15 years underwent the procedure. The mean final follow-up period was 2.8 years. Union was achieved in all patients, as seen on magnetic resonance imaging at a mean of 3 months. At follow-up, the mean loss of extension was 2°. Mean flexion was 153°. There was no loss of supination or pronation. The mean score on the short version of the Disabilities of the Arm, Shoulder and Hand questionnaire was 11. The mean Mayo Elbow score was 88. The mean Oxford Elbow score was 42. The mean visual analog scale score was 2. The mean time to return to play was 4 months. All patients continued to compete at an elite level. There were no infections or cases of fixation failure, and no patients required conversion to open surgery or needed revision surgery. CONCLUSION: Arthroscopic all-inside fixation of unstable OCD lesions is a successful technique, facilitating athletes to return to an elite level of play.

Corticosteroid or placebo injection combined with deep transverse friction massage, Mills manipulation, stretching and eccentric exercise for acute lateral epicondylitis: a randomised, controlled trial.

BACKGROUND: Lateral epicondylitis of the elbow is a frequent condition with long-lasting symptoms. Corticosteroid injection is increasingly discouraged and there is little knowledge on the combined effect of corticosteroid injection and physiotherapy for acute conditions. We wanted to investigate the efficacy of physiotherapy alone and combined with corticosteroid injection for acute lateral epicondylitis. METHODS: A randomized, controlled study with one-year follow-up was conducted in a general practice setting in Sarpsborg, Norway. We included 177 men and women aged 18 to 70 with clinically diagnosed lateral epicondylitis of recent onset (2 weeks to 3 months). They were randomly assigned to one of three treatments: physiotherapy with two corticosteroid injections, physiotherapy with two placebo injections or wait-and-see (control). Physiotherapy consisted of deep transverse friction massage, Mills manipulation, stretching, and eccentric exercises. We used double blind injection of corticosteroid and single blind assessments. The main outcome measure was treatment success defined as patients rating themselves completely recovered or much better on a six-point scale. RESULTS: One hundred fifty-seven patients (89 %) completed the trial. Placebo injection with physiotherapy showed no significant difference compared to control or to corticosteroid injection with physiotherapy at any follow-up. Corticosteroid injection with physiotherapy had a 10.6 times larger odds for success at six weeks (odds ratio 10.60, p < 0.01) compared to control (NNT = 3, 99 % CI 1.5 to 4.2). At 12 weeks there was no significant difference between these groups, but at 26 weeks the odds for success were 91 % lower (OR 0.09, p < 0.01) compared to control, showing a large negative effect (NNT = 5, 99 % CI 2.1 to 67.4). At 52 weeks there was no significant difference. Both control and placebo injection with physiotherapy showed a gradual increase in success. CONCLUSIONS: Acute lateral epicondylitis is a self-limiting condition where 3/4 of patients recover within 52 weeks. Physiotherapy with deep transverse friction massage, Mills manipulation, stretching, and eccentric exercises showed no clear benefit, and corticosteroid injection gave no added effect. Corticosteroid injections combined with physiotherapy might be considered for patients needing a quick improvement, but intermediate (12 to 26 weeks) worsening of symptoms makes the treatment difficult to recommend.

Systematic literature review of abobotulinumtoxinA in clinical trials for adult upper limb spasticity.

OBJECTIVE: The aim of this study was to elucidate clinical trial efficacy, safety, and dosing practices of abobotulinumtoxinA (ABO) treatment in adult patients with upper limb spasticity (ULS). METHODS: A systematic literature review was performed to identify randomized controlled trials and other comparative clinical studies of ABO in the treatment of adult ULS published in English between January 1991 and January 2013. Medical literature databases (PubMed, Cochrane Library, and EMBASE) were searched, and a total of 295 records were identified. Of these, 12 primary publications that evaluated ABO for the management of ULS were included in the final data report. SYNTHESIS: Total ABO doses ranged between 500 and 1500 U for ULS. Most of the studies in ULS showed statistically significant benefits (reduction in muscle tone based on Ashworth score) of ABO vs. placebo. Statistical significance was reached for most evaluations of spasticity using the Modified Ashworth Scale. Statistically significant effects on active movement and pain were demonstrated, albeit less consistently. ABO was generally well tolerated across the individual studies; most adverse events reported were considered unrelated to treatment. Adverse events considered associated with ABO treatment included fatigue, tiredness, arm pain, skin rashes, flu-like symptoms, worsening of spasm, and weakness. CONCLUSIONS: On the basis of data extracted from 12 randomized clinical studies, a strong evidence base (9/12 studies) exists for the use of ABO to reduce ULS caused by stroke.

Técnica de Thrust para la disfunción posterior de la cabeza del radio / Thrust technique for posterior disfunction of the radial head

Las disfunciones osteopáticas en el codo pueden causar absentismo laboral, con el gasto económico que ello conlleva para la sociedad, debido a la alta incidencia con la que estas disfunciones se presentan. Una de las lesiones osteopáticas que se pueden dar en el codo, es la disfunción de cabeza de radio posterior, que provoca un aumento del tono del músculo supinador corto, que a su vez puede referir dolor en la región externa del brazo y antebrazo. El objetivo de la técnica de thrust para la cabeza de radio posterior con contacto indexial, será anteriorizar la cabeza del radio, para así poder recuperar la funcionalidad en la articulación del codo. Para realizar correctamente la técnica, previamente habrá que llegar a un diagnóstico adecuado basado en la inspección, palpación, pruebas de movilidad, pruebas musculares, pruebas ortopédicas y radiología (AU)

Osteopathic dysfunctions in the elbow can cause work absenteeism, and the economic expense that this entails for society, due to the high incidence with which these dysfunctions occur. One of the osteopathic injuries that can occur in the elbow is posterior radial head dysfunction, which causes an increase in tone of the short supinator muscle, which in turn may refer pain in the external region of the arm and forearm. The objective of the thrust technique for the posterior radial head with indexial contact will be to forward the radial head in order to recover the functionality at the elbow joint. In order to correctly perform the technique, a proper diagnosis based on inspection, palpation, mobility tests, muscle tests, orthopedic tests and radiology must be previously arrived at (AU)

Deficits in startle-evoked arm movements increase with impairment following stroke.

OBJECTIVE: The startle reflex elicits involuntary release of planned movements (startReact). Following stroke, startReact flexion movements are intact but startReact extension movements are impaired by task-inappropriate flexor activity impeding arm extension. Our objective was to quantify deficits in startReact elbow extension movements, particularly how these deficits are influenced by impairment. METHODS: Data were collected in 8 stroke survivors performing elbow extension following two non-startling acoustic stimuli representing "get ready" and "go", respectively. Randomly, the "go" was replaced with a startling acoustic stimulus. We hypothesized that task-inappropriate flexor activity originates from unsuppressed classic startle reflex. We expected that increasing damage to the cortex (increasing impairment) would relate to increasing task-inappropriate flexor activity causing poor elbow extension movement and target acquisition. RESULTS: Task-inappropriate flexor activity increased with impairment resulting in larger flexion deflections away from the subjects' intended target corresponding to decreased target acquisition. CONCLUSIONS: We conclude that the task-inappropriate flexor activity likely results from cortical or corticospinal damage leading to an unsuppressed or hypermetric classic startle reflex that interrupts startReact elbow extension. SIGNIFICANCE: Given startReact's functional role in compensation during environmental disturbances, our results may have important implications for our understanding deficits in stroke survivor's response to unexpected environmental disturbances.

A 5-22-year follow-up study of stemmed alumina ceramic total elbow arthroplasties with cement fixation for patients with rheumatoid arthritis.

BACKGROUND: We determined mid to long-term results of total elbow arthroplasty (TEA) by use of unlinked elbow prostheses with solid alumina ceramic trochleae, and ceramic ulnar stems (stemmed Kyocera type I; SKC-I) for patients with rheumatoid arthritis. PATIENTS AND METHODS: Fifty-four elbows of 39 patients were available for detailed clinical and radiographic review after a follow-up period of at least 5 years. The mean follow-up period was 12.6 years (range 5-22 years). Clinical condition before and after surgery was assessed by use of a modified version of the Mayo Elbow Performance Score (MEPS; 0-100 points) and a Japan Orthopaedic Association Elbow score (JOA score; 0-100 points). The radiographs were reviewed and loosening was defined as a progressive radiolucent line >1 mm wide that was completely circumferential around the prosthesis. Clinical records of post-operative events affecting the elbows were used for survival analysis of the prostheses using the Kaplan-Meier method. RESULTS: The average modified MEPS and JOA scores improved significantly from 39.7 ± 14.3 to 44.7 ± 9.4, respectively, pre-operatively, to 89.7 ± 15.4 and 83.1 ± 12.8, respectively, post-operatively (P < 0.0001). The functional assessment score also improved from 4.9 ± 2.8 to 8.5 ± 3.3 points (P < 0.0001). With loosening or implant revision defined as end points, the likelihood of survival of the prosthesis for up to 20 years was 92.6% (95% confidence interval (CI), 85.6-100.0) or 86.3 % (95 % CI 75.0-97.6), respectively. CONCLUSION: Satisfactory clinical results were obtained after TEA using SKC-I prostheses, which provided excellent pain relief and functional range of motion. The results of our study reveal the high reliability over a long period of the cemented SKC-I prosthesis with an alumina ceramic component.

[Case-control study on comprehensive traditional Chinese medicine therapy for preventing postsurgery stiffness after operation for terrible triad of the elbow].

OBJECTIVE: To study therapeutic effects of comprehensive traditional Chinese medicine therapy for preventing postsurgery stiffness after operation for terrible triad of the elbow. METHODS: From December 2008 to December 2013,32 patients with elbow triad were randomly divided into two groups: therapy group and control group. There were 17 patients in control group including 12 males and 5 females with a mean age of (41.0 ± 7.1) years old. The patients in control group were received the past procedure therapy. There were 15 patients in therapy group, including 10 males and 5 females with a mean age of (41.3 ± 7.6) years old. The patients in therapy group were received comprehensive traditional Chinese medicine therapy, including passive exercise training at early stage (0 to 2 weeks after operation), transition from passive to active exercise training at middle stage (3 to 4 weeks after operation), and active exercise training at late stage (5 to 12 weeks after operation). Other treatment methods, such as orally taking or externally use of Chinese herbal medicine, manipulation and physiotherapy, were used at all stages. The Mayo Elbow Performance Score, patient satisfaction and complications were evaluated and analyzed. RESULTS: All the patients were followed up, and the mean duration was 7.5 months. There were no complications such as internal fixation loosing, obvious displacement fracture and heterotopic ossification occurred. The Mayo score and patient satisfaction in therapy group were higher than those in control group (t = 12.78, P = 0.00; χ2 = 8.719, P = 0.003). Seven patients needed reoperation in control group, compared with 1 patient in therapy group (χ2 = 4.626, P = 0.032). CONCLUSION: The comprehensive traditional Chinese medicine therapy is effective to prevent postoperative stiffness after operation for terrible triad of the elbow by using different methods at different stages, which is worthy of spread and application.

Acupuncture for lateral epicondylitis (tennis elbow): study protocol for a randomized, practitioner-assessor blinded, controlled pilot clinical trial.

BACKGROUND: Lateral epicondylitis is the most frequent cause of pain around the elbow joint. It causes pain in the region of the elbow joint and results in dysfunction of the elbow and deterioration of the quality of life. The purpose of this study is to compare the effects of ipsilateral acupuncture, contralateral acupuncture and sham acupuncture on lateral epicondylitis. METHODS/DESIGN: Forty-five subjects with lateral epicondylitis will be randomized into three groups: the ipsilateral acupuncture group, contralateral acupuncture group and the sham acupuncture group. The inclusion criteria will be as follows: (1) age between 19 and 65 years with pain due to one-sided lateral epicondylitis that persisted for at least four weeks, (2) with tenderness on pressure limited to regions around the elbow joint, (3) complaining of pain during resistive extension of the middle finger or the wrist, (4) with average pain of NRS 4 or higher during the last one week at a screening visit and (5) voluntarily agree to this study and sign a written consent. Acupuncture treatment will be given 10 times in total for 4 weeks to all groups. Follow up observations will be conducted after the completion of the treatment, 8 weeks and 12 weeks after the random assignment. Ipsilateral acupuncture group and contralateral acupuncture group will receive acupuncture on LI4, TE5, LI10, LI11, LU5, LI12 and two Ashi points. The sham acupuncture group will receive treatment on acupuncture points not related to the lateral epicondylitis using a non-invasive method. The needles will be maintained for 20 minutes. The primary outcome will be differences in the visual analogue scale (VAS) for elbow pain between the groups. The secondary outcome will be differences in patient-rated tennis elbow evaluation (PRTEE), pain-free/maximum grip strength (Dynamometer), pressure pain threshold, clinically relevant improvement, patient global assessment, and the EQ-5D. The data will be analyzed with the paired t-test and ANCOVA (P <0.05). DISCUSSION: The results of this study will allow evaluation of contralateral acupuncture from two aspects. First, if the contralateral acupuncture shows the effects similar to ipsilateral acupuncture, this will establish clinical basis for contralateral acupuncture. Second, if the effects of contralateral acupuncture are not comparable to the effects of ipsilateral acupuncture, but are shown to be similar to the effects of the sham acupuncture, we can establish the basis for using the same acupoints of the unaffected side as a control in acupuncture clinical studies. TRIAL REGISTRATION: This trial has been registered with the 'Clinical Research Information Service (CRIS)', Republic of Korea: KCT0000628.

Physical therapy, corticosteroid injection, and extracorporeal shock wave treatment in lateral epicondylitis. Clinical and ultrasonographical comparison.

The aim of this study was to compare--clinically and ultrasonographically--the therapeutic effects of physical therapy modalities (hot pack, ultrasound therapy, and friction massage), local corticosteroid injection, and extracorporeal shock wave treatment (ESWT) in lateral epicondylitis (LE). Fifty-nine elbows of 59 patients with LE were randomized into three treatment groups receiving either physical therapy, a single corticosteroid injection, or ESWT. Visual analogue scale (VAS) was used to assess pain intensity, Jamar hydraulic dynamometer for grip strength, finger dynamometer for pinch strength (before treatment, on the first, third, and sixth months of treatment). All subjects were also evaluated with ultrasonography before and 6 months after treatment. In all groups, VAS scores of the patients were found to decrease significantly on the first, third, and sixth months of treatment. With respect to grip strength evaluations, the increase after treatment was significant only on the first month in group II; on the first and third months in group I; and on the first, third, and sixth months of treatment in group III. Pinch strength and ultrasonographical findings did not change during follow-up in any group. We imply that physical therapy modalities, corticosteroid injection, and ESWT have favorable effects on pain and grip strength in the early period of LE treatment. The increase in grip strength lasts longer with ESWT. On the other hand, ultrasonographic findings do not change in the first six months of these treatment methods.
