Abstract
Objective: To compare the effectiveness of Cyriax physiotherapy, a supervised exercise programme, and polarized polychromatic non-coherent light (Bioptron light) in the treatment of lateral epicondylitis. Design: Controlled clinical trial. Setting: Rheumatology and rehabilitation centre. Subjects: This study was carried out with 75 patients who had lateral epicondylitis. They were allocated to three groups by sequential allocation. Interventions: Group A ( n=25) was treated with Cyriax physiotherapy. A supervised exercise programme was given to group B ( n=25). Group C ( n=25) received polarized polychromatic non-coherent light (Bioptron light). All patients received three treatments per week for four weeks. Outcomes: Pain was evaluated using a visual analogue scale and function using a visual analogue scale and pain-free grip strength at the end of the four-week course of treatment (week 4), one month (week 8), three months (week 16) and six months (week 28) after the end of treatment. Results: The supervised exercise programme produced the largest effect in the reduction of pain and in the improvement of function at the end of the treatment ( P<0.05) and at any of the follow-up time points ( P<0.05). Conclusion: The supervised exercise programme should be the first treatment option for therapists when they manage lateral epicondylitis patients. If this is not possible, Cyriax physiotherapy and polarized polychromatic non-coherent light (Bioptron light) may be suitable.

Abstract
STUDY DESIGN Controlled laboratory study. OBJECTIVE To determine the time course of dexamethasone sodium phosphate (Dex-P) during iontophoresis to underlying tissues using microdialysis. BACKGROUND In human participants, real-time information of Dex-P transdermal delivery during iontophoresis is unknown. METHODS Sixty-four healthy male participants (mean ± SD age, 24.2 ± 3.3 years; height, 181.8 ± 26.1 cm; mass, 82.4 ± 11.8 kg; subcutaneous fat thickness, 0.61 ± 0.19 cm) were randomly assigned into 1 of 6 groups: (1) 1-mA current, 1-mm probe depth; (2) 1-mA current, 4-mm probe depth; (3) 2-mA current, 1-mm probe depth; (4) 2-mA current, 4-mm probe depth; (5) in vivo retrodialysis; and (6) skin perfusion flowmetry. Microdialysis probes were used to assess the combined recovery (Dex-total) of Dex-P, dexamethasone, and its metabolite. RESULTS There was no difference in Dex-total between current intensities (P = .99), but a greater amount of Dex-total was recovered superficially at 1 mm compared to the 4-mm depth (P<.0001). Peak concentration mean ± SD values for the 1- and 2-mA currents at 1 mm were 10.8 ± 8.1 and 7.7 ± 5.5 µg/mL, and at 4 mm were 2.0 ± 0.8 and 1.3 ± 0.9 µg/mL, respectively. Peak skin perfusion was 741.4% ± 408.7% and 711.6% ± 260.8% at baseline for 1- and 2-mA intensities, respectively. Skin perfusion returned to baseline levels earlier during 1-mA intensity at a 110 mA · min dose within the treatment, compared to 2 mA at 60 minutes posttreatment. CONCLUSION Transdermal delivery of Dex-P during iontophoresis was successfully measured in vivo through human skin. Measurable concentrations of Dex-total were found regardless of current intensity. Although current-induced vasodilation occurred, it did not significantly affect the tissue accumulation of Dex-total.

Abstract
Background Deep transverse friction massage, one of several physical therapy interventions suggested for the management of tendinitis pain, was first demonstrated in the 1930s by Dr James Cyriax, a renowned orthopedic surgeon in England. Its goal is to prevent abnormal fibrous adhesions and abnormal scarring. This is an update of a Cochrane review first published in 2001.Objectives To assess the benefits and harms of deep transverse friction massage for treating lateral elbow or lateral knee tendinitis.Search methods We searched the following electronic databases: the specialized central registry of the Cochrane Field of Physical and Related Therapies,the Cochrane Central Register of Controlled Trials (CENTRAL),MEDLINE, EMBASE, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), Clinicaltrials.gov, and the Physiotherapy Evidence Database (PEDro), up until July 2014. The reference lists of these trials were consulted for additional studies.Selection criteria All randomized controlled trials (RCTs) and controlled clinical trials (CCTs) comparing deep transverse friction massage with control or other active interventions for study participants with two eligible types of tendinitis (ie, extensor carpi radialis tendinitis (lateral elbow tendinitis, tennis elbow or lateral epicondylitis or lateralis epicondylitis humeri) and iliotibial band friction syndrome (lateral knee tendinitis)) were selected. Only studies published in English and French languages were included.Data collection and analysis Two review authors independently assessed the studies on the basis of inclusion and exclusion criteria. Results of individual trials were extracted from the included study using extraction forms prepared by two independent review authors before the review was begun.Data were cross-checked by a third review author. Risk of bias of the included studies was assessed using the "Risk of bias"tool of The Cochrane Collaboration. A pooled analysis was performed using mean difference (MD) for continuous outcomes and risk ratio (RR)for dichotomous outcomes with 95% confidence intervals (CIs).Main results Two RCTs (no new additional studies in this update) with 57 participants met the inclusion criteria. These studies demonstrated high risk of performance and detection bias, and the risk of selection, attrition, and reporting bias was unclear.The first study included 40 participants with lateral elbow tendinitis and compared (1) deep transverse friction massage combined with therapeutic ultrasound and placebo ointment (n = 11) versus therapeutic ultrasound and placebo ointment only (n = 9) and (2)deep transverse friction massage combined with phonophoresis (n = 10) versus phonophoresis only (n = 10). No statistically significant differences were reported within five weeks for mean change in pain on a 0 to 100 visual analog scale (VAS) (MD -6.60, 95%CI -28.60 to 15.40; 7% absolute improvement), grip strength measured in kilograms of force (MD 0.10, 95% CI -0.16 to 0.36) and function ona 0 to 100 VAS (MD -1.80, 95% CI -0.18.64 to 15.04; 2% improvement), pain-free function index measured as the number of painfree items (MD 1.10, 95% CI -1.00 to 3.20) and functional status (RR 3.3, 95% CI 0.4 to 24.3) for deep transverse friction massage,and therapeutic ultrasound and placebo ointment compared with therapeutic ultrasound and placebo ointment only. Likewise for deep transverse friction massage and phonophoresis compared with phonophoresis alone, no statistically significant differences were found for pain (MD -1.2, 95% CI -20.24 to 17.84; 1% improvement), grip strength (MD -0.20, 95% CI -0.46 to 0.06) and function (MD3.70, 95% CI -14.13 to 21.53; 4% improvement). In addition, the GRADE (Grades of Recommendation, Assessment, Development and Evaluation) approach was used to evaluate the quality of evidence for the pain outcome, which received a score of "very low".Pain relief of 30% or greater, quality of life, patient global assessment, adverse events, and withdrawals due to adverse events were not assessed or reported.The second study included 17 participants with iliotibial band friction syndrome (knee tendinitis) and compared deep transverse friction massage with physical therapy intervention versus physical therapy intervention alone, at two weeks. Deep transverse friction massage with physical therapy intervention showed no statistically significant differences in the three measures of pain relief on a 0 to 10 VAS when compared with physical therapy alone: daily pain (MD -0.40, 95% CI -0.80 to -0.00; absolute improvement 4%), pain while running (scale from 0 to 150) (MD -3.00, 95% CI -11.08 to 5.08), and percentage of maximum pain while running (MD -0.10, 95% CI -3.97 to 3.77). For the pain outcome, absolute improvement showed a 4% reduction in pain. However, the quality of the body of evidence received a grade of "very low."Pain relief of 30% or greater, function, quality of life, patient global assessment of success, adverse events, and withdrawals due to adverse events were not assessed or reported.Authors' conclusions We do not have sufficient evidence to determine the effects of deep transverse friction on pain, improvement in grip strength, and functional status for patients with lateral elbow tendinitis or knee tendinitis, as no evidence of clinically important benefits was found.The confidence intervals of the estimate of effects overlapped the null value for deep transverse friction massage in combination with physical therapy compared with physical therapy alone in the treatment of lateral elbow tendinitis and knee tendinitis. These conclusions are limited by the small sample size of the included randomized controlled trials. Future trials, utilizing specific methods and adequate sample sizes, are needed before conclusions can be drawn regarding the specific effects of deep transverse friction massage on lateral elbow tendinitis.

Abstract
BACKGROUND AND PURPOSE This study was designed to evaluate the effects of competing ions and electroosmosis on the transdermal iontophoresis of dexamethasone phosphate (Dex-Phos) and to identify the optimal conditions for its delivery. METHODS The experiments were performed using pig skin, in side-by-side diffusion cells (0.78 cm(2)), passing a constant current of 0.3 mA via Ag-AgCl electrodes. Dex-Phos transport was quantified for donor solutions (anodal and cathodal) containing different drug concentrations, with and without background electrolyte. Electrotransport of co-ion, citrate, and counterions Na(+) and K(+) also was quantified. The contribution of electroosmosis was evaluated by measuring the transport of the neutral marker (mannitol). RESULTS Electromigration was the dominant mechanism of drug iontophoresis, and reduction in electroosmotic flow directed against the cathodic delivery of Dex-Phos did not improve drug delivery. The Dex-Phos flux from the cathode was found to be optimal (transport number of approximately 0.012) when background electrolyte was excluded from the formulation. In this case, transport of the drug is limited principally by the competition with counterions (mainly Na(+) with a transport number of approximately 0.8) and the mobility of the drug in the membrane. DISCUSSION AND CONCLUSION Dex-Phos must be delivered from the cathode and formulated rationally, excluding mobile co-anions, to achieve optimal iontophoretic delivery.

Abstract
According to Fascial Manipulation theory, patellar tendon pain is often due to uncoordinated quadriceps contraction caused by anomalous fascial tension in the thigh. Therefore, the focus of treatment is not the patellar tendon itself, but involves localizing the cause of this incoordination, considered to be within the muscular fascia of the thigh region. Eighteen patients suffering from patellar tendon pain were treated with the Fascial Manipulation technique. Pain was assessed (in VAS) before (VAS 67.8/100) and after (VAS 26.5/100) treatment, plus a follow-up evaluation at 1 month (VAS 17.2/100). Results showed a substantial decrease in pain immediately after treatment (p<0.0001) and remained unchanged or improved in the short term. The results show that the patellar tendon may be only the zone of perceived pain and that interesting results can be obtained by treating the muscular fascia of the quadriceps muscle, whose alteration may cause motor incoordination and subsequent pathology.

Abstract
STUDY DESIGN Experimental laboratory study. OBJECTIVES To measure the transmission of dexamethasone sodium phosphate (DEX-P) using iontophoresis as a function of skinfold tissue thickness and time elapsed between treatment and tissue extraction. BACKGROUND Iontophoresis is a modality used in physical therapy with the intent to drive medications through the skin to underlying tissues using a direct electrical current. DEX-P is the most commonly used medication with iontophoresis and is used to treat a variety of connective tissue conditions. METHODS AND MEASURES Sixteen adults undergoing anterior cruciate ligament reconstructive surgery using the semitendinosis/gracilis autograft received a 40-mA-min dose of iontophoresis with 0.4% DEX-P superficial to a slip of the distal semitendinosis tendon prior to surgery. The tendon slip was extracted within 4 hours. Time between treatment and tissue extraction and skinfold thickness were measured. Analysis was performed on the slip of the semitendinosis using high-performance liquid chromatography mass spectrum. RESULTS Of the 16 subjects (10 female, 6 male; mean age, 33 years), 7 had measurable amounts of DEX-P in the tendon slip (4 female, 3 male; mean age, 34 years). The average concentration in the 16 subjects was 2.9 ng/g of tendon tissue. There was no correlation between DEX-P absorbed and skinfold thickness (r = -0.08, P = .79) or time elapsed (r = 0.25, P = .38). In a subset of the 7 individuals that showed measurable levels of DEX-P absorbed, the average concentration of DEX-P was 6.6 ng/g of tendon tissue, and there was a relationship between DEX-P concentrations and time elapsed that did not reach statistical significance (r = 0.71, P = .11). CONCLUSIONS Iontophoresis appears to facilitate the transmission of dexamethasone to connective tissues in humans with skinfold thickness up to at least 30 mm. The absorption of the dexamethasone seemed to continue to occur for up to 4 hours after delivery. It is not clear why DEX-P was measured in only 7 of the 16 subjects. LEVEL OF EVIDENCE Therapy, level 5.

Abstract
BACKGROUND Iontophoresis ostensibly facilitates the delivery of medications through the skin to underlying tissues using a direct electrical current. Dexamethasone is the most commonly used medication with iontophoresis to treat a variety of connective tissue disorders. HYPOTHESIS Iontophoresis will facilitate the absorption of dexamethasone into connective tissue compared with diffusion. STUDY DESIGN Controlled laboratory study. METHODS Twenty-nine adults undergoing anterior cruciate ligament reconstructive surgery using the semitendinosus/gracilis autograft were randomly assigned to either a true iontophoresis (TI) or sham iontophoresis (SI). In the TI group, a 40-mA/min dose of iontophoresis using a 0.4% (4 mg/mL) solution of dexamethasone was used targeting the semitendinosus tendon just before surgery. The SI group underwent the same treatment, but the machine was not turned on. Tissue was extracted within 4 hours of treatment and analyzed for dexamethasone. In addition, 2 control samples were sent to the laboratory for analysis. RESULTS There was a statistically significant difference in dexamethasone concentrations between the groups (P = .0216). Of the 16 samples in the TI group, 8 had measurable amounts of dexamethasone, with an average concentration of 2.906 ng/g of tendon tissue. In the SI group, 1 of the 13 samples had measurable amounts of dexamethasone with an average concentration of 0.205 ng/g of tendon tissue. The control samples contained no dexamethasone. CONCLUSION Iontophoresis facilitates the transmission of dexamethasone to connective tissues in humans. CLINICAL RELEVANCE Iontophoresis can deliver dexamethasone to connective tissues in humans.

Abstract
OBJECTIVE To compare the effectiveness of an exercise programme, pulsed ultrasound and transverse friction in the treatment of chronic patellar tendinopathy. DESIGN Randomized controlled trial. SETTING Rheumatology and Rehabilitation Centre. SUBJECTS This study was carried out with 30 patients who had chronic patellar tendinopathy. They were randomized into three groups. INTERVENTIONS Group A (n = 10) was treated with exercise programme. Pulsed ultrasound was given to group B (n = 10). Group C (n = 10) received transverse friction. All patients received three treatments per week for four weeks. OUTCOMES Patients' pain was evaluated at the end of the four-week course of treatment (week 4), one month (week 8) and three months (week 16) after the end of treatment. RESULTS The exercise programme was statistically significantly better than the other two treatments at the end of treatment (chi2 = 12.21, p < 0.01), one month (chi2 = 23.2, p < 0.001) and three months (chi2 = 23.2, p < 0.001) after the end of the treatment. CONCLUSION Although the results suggested that the exercise programme was more effective treatment than ultrasound and transverse friction at the end of the treatment as well as at the follow-ups, future controlled studies are needed to establish the relative and absolute effectiveness of each of the three treatment interventions.

Abstract
Traditional therapeutic modalities include cryotherapy, sonotherapy, pulsed electrical stimulation, transcutaneous electrical nerve stimulation, high-volt pulsed current, and iotopheresis. Alternative modalities include acupuncture, magnetic field therapy, biofeedback,and massage. All therapeutic modalities should be considered adjuncts to progressive functional exercise. Controlled studies rarely reach consensus regarding the efficacy of therapeutic modalities,so their use should be individualized to the patient.

Abstract
BACKGROUND A better treatment modality is needed to control the pain of medial or lateral epicondylitis (tennis elbow). HYPOTHESIS Dermal iontophoretic administration of dexamethasone sodium phosphate will be significantly more effective in controlling pain than a placebo in patients with medial or lateral elbow epicondylitis. STUDY DESIGN Randomized, double-blinded, placebo-controlled study. METHODS On six occasions, 1 to 3 days apart within 15 days, 199 patients with elbow epicondylitis received 40 mA-minutes of either active or placebo treatment. RESULTS Dexamethasone produced a significant 23-mm improvement on the 100-mm patient visual analog scale ratings, compared with 14 mm for placebo at 2 days and 24 mm compared with 19 mm at 1 month. More patients treated with dexamethasone than those treated with placebo scored moderate or better on the investigator's global improvement scale (52% versus 33%) at 2 days, but the difference was not significant at 1 month (54% versus 49%). Investigator-rated pain and tenderness scores favored dexamethasone over placebo at 2 days. Patients completing six treatments in 10 days or less had better results than those treated over a longer period. CONCLUSIONS Iontophoresis treatment was well tolerated by most patients and was effective in reducing symptoms of epicondylitis at short-term follow-up.

Abstract
PURPOSE Sixty-eight skeletally mature New Zealand white rabbits were used to study the effects of iontophoresis- and injection-delivered sodium phosphate dexamethasone (DX) on the morphologic, histologic, microscopic, and biomechanical properties of uninjured rabbit patellar tendons over an initial 14-d period. METHODS Three control (untreated, placebo iontophoresis, and placebo injection) groups and two treatment (iontophoresis and injection) groups underwent serum, ELISA tendon, histology, electron microscopy, and biomechanical analysis. RESULTS Serum DX levels were detectable and quantifiable in both treatment groups at 1 h but were significantly greater (P < 0.05) in the injected group (11.29 ng.mL-1) compared with the iontophoresis group (6.34 ng.mL-1). The most significant histologic finding was a lack of a cellular inflammatory response in the DX-treated groups at 24 h. Ultrastructural analysis produced no significant differences between size or size ratio of collagen fibrils among any groups. Morphologic examination revealed only injection puncture marks seen in appropriate tendons. Biomechanical testing produced disruption at the patellar insertion in 81% of the specimens. No injected tendon failed at the injection site. Normalized biomechanical properties included: 1) Stiffness increased in control and iontophoresis groups from 1 to 24 h, then gradually declined; the DX-injected specimens showed a similar but delayed effect. 2) Peak load at failure for iontophoresis and control groups was greatest at 24 h. The DX-injected group again showed a delayed response. 3) In general, total energy to failure revealed no significant differences between groups at any time period. CONCLUSION It appears that iontophoresis or injection-delivered DX may produce anti-inflammatory effects without significantly altering ultrastructural or biomechanical characteristics of the rabbit patellar tendon within an initial 14-d period.

Abstract
BACKGROUND Deep transverse friction massage (DTFM) is one of several physiotherapy interventions suggested for the management of pain due to iliotibial band friction syndrome (ITBFS). OBJECTIVES To assess the effectiveness of DTFM for treating ITBFS observed in runners. SEARCH STRATEGY We searched the Medline, Embase, Healthstar, Sports Discus, CINAHL, the Cochrane Controlled Trials Register, PEDro, the specialized registry of the Cochrane musculoskeletal group and the Cochrane field of Physical and Related Therapies up to the end of December 2000, using the sensitive search strategy developed by the Cochrane Collaboration. The search was complemented with bibliography searching of the reference list of the trials retrieved from the electronic search. Key experts in the area were contacted for further published and unpublished articles. SELECTION CRITERIA All randomized controlled trials (RCTs) and controlled clinical trials (CCTs) comparing therapeutic ultrasound against placebo or another active intervention in patients with patellofemoral pain syndrome were selected. DATA COLLECTION AND ANALYSIS Two reviewers determined the studies to be included based on inclusion and exclusion criteria (LB, VR). Data were independently abstracted by two reviewers (VR, LB), and checked by a third reviewer (BS) using a pre-developed form of the Cochrane Musculoskeletal Group. The same two reviewers, using a validated scale, assessed the methodological quality of the RCTs and CCTs independently. Iliotibial band friction syndrome outcome measures were extracted from the publications. The pooled analysis was performed using weighted mean differences (WMDs) for pain relief as described as 1) daily pain; 2) pain while running and 3) percentage of maximum pain when running. A chi-square test was used to assess heterogeneity among trials. Fixed effects models were used throughout and random effects for outcomes showing heterogeneity. MAIN RESULTS One RCT, including 17 patients with ITBFS was included. The experimental group (DTFM combined to rest, stretching exercises, cryotherapy and therapeutic ultrasound) (n=9) was compared to the control group (rest, stretching exercises, cryotherapy and therapeutic ultrasound only) (n=8). This trial showed no statistical difference in the three types of pain relief measured after four consecutive sessions of DTFM combined with other physiotherapy modalities for runners. Despite lack of statistical significance, there was a clinically important relative percentage difference in pain while running of 22%. REVIEWER'S CONCLUSIONS DTFM combined with other physiotherapy modalities did not show consistent benefit over control of pain for runners experiencing ITBFS. These conclusions are limited by the low methodological quality of the one small sample size trial (n=17) included. No conclusions can be drawn about the use or non use of DTFM for the treatment of ITBFS. Future trials, utilizing appropriate methods and adequate sample sizes are needed before conclusions can be drawn regarding the effect of massage on iliotibial band friction syndrome.

Abstract
Objective:To assess the efficacy of lidocaine iontophoresis on myofascial trigger-point pain.Setting:University athletic training facility.Design:Randomized, double-blind, placebo-controlled, repeated-measures.Subjects:Twenty-three subjects with sensitive trigger points over the trapezius.Intervention:Placebo iontophoresis treatment without current or lidocaine, control treatment using distilled water and normal current dose, medicated treatment using 1% lidocaine and normal current dose.Main Outcome Measure:Trigger-point pressure threshold assessed with an algometer.Results:ANOVA revealed a significant difference among treatments (F2,40= 7.38,P< .01). Post hoc comparisons revealed a significant difference in pressure threshold between the lidocaine treatment and the control (P= .01) and placebo (P= .001) treatments. Effect sizes of .28 and .39, respectively, were found for these comparisons.Conclusions:Although the data revealed significant differences between treatments, the small effect sizes and magnitude of the pressure-sensitivity deviation scores suggest that iontophoresis with 1% lidocaine is ineffective in treating trigger points.

Abstract
When pain and effusion have been minimized and patients assume appropriate knee posture at rest and during exercise, the extent of postinjury or postoperative quadriceps femoris neuromuscular inhibition and avoidance during locomotion is reduced. Restoring normal lower-extremity ROM and musculotendinous extensibility (with consideration for biarticular muscles) is foundational to the implementation of an exercise program that integrates the trunk, hip, and ankle muscles into dynamic knee-stabilization challenges while addressing isolated quadriceps femoris deficiencies. Cardiovascular conditioning should be addressed as early as feasible. Although programs generally address anaerobic and aerobic energy systems, increasing patients' fatigue resistance, as evidenced by prolonged maintenance of appropriate functional exercise techniques and body control without verbalized discomfort or observed movement-avoidance patterns, ensures therapists that neuromuscular responsiveness for dynamic knee stabilization is improving.

Abstract
The techniques of iontophoresis and electroporation can be used to enhance topical and transdermal drug delivery. Iontophoresis applies a small low voltage (typically 10 V or less) continuous constant current (typically 0.5 mA/cm2 or less) to push a charged drug into skin or other tissue. In contrast, electroporation applies a high voltage (typically, ?100 V) pulse for a very short (micros-ms) duration to permeabilize the skin. This electric assistance of drug delivery across skin will expand the scope of transdermal delivery to hydrophilic macromolecules such as the drugs of biotechnology. These two techniques differ in several aspects such as the mode of application and pathways of transport but can be used together for effective drug delivery. Iontophoresis is already used clinically in physical therapy clinics and is close to commercialization for development of a systemic delivery patch with miniaturized circuits and similar in overall size to a passive patch. The use of electroporation for drug delivery is relatively new and is being actively researched.
