Investigation of the functional and biomechanical effect of instrument-assisted soft tissue mobilization technique in individuals with asymptomatic dynamic knee valgus - Randomized controlled trial.

Although there are studies showing that myofascial release will increase muscle force production, the contribution of its application alone to muscle force production has not been examined. Aim of the study is to investigate the effect of instrument-assisted soft tissue mobilization (IASTM) on eccentric strength, frontal plane projection angle (FPPA), dynamic (DPS), and static postural stability (SPS), femoral internal rotation (FIR) angle in females with dynamic knee valgus (DKV). A total of 44 recreationally active females with asymptomatic DKV (age: 21,39 ± 1,79, body mass index: 20,09 ± 2,45) participated and were randomly assigned to either control group (CG) or IASTM group (IASTMG). Participants' eccentric contraction strength, FPPA, DPS, SPS, and FIR on the involved leg were measured pre- and post. IASTM application was applied to IASTMG for 6 weeks, twice a week, for 5 min, using Graston Technique® instruments on gluteus medius. CG received no intervention. In comparison of ECS difference values, change in IASTMG was found to be statistically significantly higher than CG (p = .004; p < .01). There was no statistical difference in comparison of FIR and FPPA values (respectively p = .213, p = .360; p < .05). In SPS and DPS evaluation, a statistically significant improvement was observed in favor of IASTMG in comparison of both intergroup and difference values (p < .05 for all). Strength gain without exercise can increase postural stability, but it isn't sufficient to correct faulty movement patterns. We recommend adding IASTM to injury prevention programs, but there is a need to investigate the effect of IASTM with technique correction feedback.

Unknotting tech neck by breaking the cycle of pain and disability: Comparing the impact of instrument assisted soft tissue mobilization on specific muscles and superficial back arm line.

BACKGROUND: Computer professionals often develop a forward head posture due to prolonged hours of computer use, leading to neck pain. Instrument-assisted soft tissue mobilization (IASTM), an advanced technique for treating myofascial trigger points, has become increasingly popular for addressing these musculoskeletal issues. OBJECTIVES: The study aimed to compare the effectiveness of IASTM mobilization on SBAL (superficial back arm line) and SM(specific muscles-upper trapezius, levator scapulae, and sternocleidomastoid) in managing chronic neck pain among computer professionals. PARTICIPANTS & METHODS: The study involved 62 computer professionals, randomly divided into two groups. Group A received IASTM on SBAL and group B received IASTM on SM for neck pain each receiving three sessions weekly for four weeks. Outcome variables like Neck Disability Index (NDI), NPRS(Neck Pain Rating Scale), Craniovertebral angle (CVA), and range of motion (ROM) for flexion, and side flexion (right & left side) were evaluated at baseline, 2 weeks and 4 weeks. RESULTS: Significant improvement in NPRS were observed in both the SBAL and SM groups after 2 weeks of IASTM, wth the SBAL group demonstrating greater improvement. At 4 weeks, IASTM on SBAL showed significantly higher improvements in NPRS, CVA, NDI, and flexion compared to the SM group. The repeated measures ANOVA indicated a significant main effect of both time and group, along with a significant interaction between time and group for all outcome variables, except for CVA. CONCLUSION: The study indicates that IASTM on SBAL may offer a more effective treatment for chronic neck pain in computer professionals compared to targeting specific muscles.

Association between myofascial trigger point therapy and conditioned pain modulation.

INTRODUCTION: Myofascial trigger point therapy (MTrP) is a widely used therapeutic approach, although the underlying mechanisms remain unclear. Mechanisms discussed include peripheral involvement of muscles as well as central pain modulating processes such as the conditioned pain modulation (CPM). The aim of this study was to investigate whether the analgesic response of MTrP and the analgesic response of CPM correlate in asymptomatic participants in order to identify shared underlying mechanisms of MTrP and CPM. METHOD: Both, CPM and MTrP protocols consisted of heat-based test stimuli (heat pain thresholds before and after the intervention) and pressure-based (conditioning) stimuli. Asymptomatic participants (n = 94) were randomly assigned to receive either mild, intense or no pressure stimuli (between-group design) to both the fingernail and the MTrP of the infraspinatus muscle (within-group design). Pressure stimuli at both locations (fingernail, MTrP) were applied with a pressure algometer for 120 s and continuously adjusted to maintain a constant pain intensity of mild or intense pain. All thermal stimuli were applied on the lower leg with a thermal stimulator. RESULTS: A significant correlation was shown between the analgesic effect of CPM and MTrP therapy for mild (r = 0.53, p = 0.002) and intensive stimuli (r = 0.73, p < 0.001). 17.3% of the variance of the MTrP effect were explained by CPM after mild stimulation, and 47.1% after intense stimulation. Pain-related characteristics did not explain the variance within the analgesic response using a regression analysis. CONCLUSIONS: Between the analgesic responses following MTrP and CPM paradigms, a moderate to strong correlation was observed, suggesting shared underlying mechanisms.

Evaluation of the efficacy of manual soft tissue therapy and therapeutic exercises in patients with pain and limited mobility TMJ: a randomized control trial (RCT).

The limited number of randomized controlled trials (RCTs) comparing the efficacy of soft tissue manual therapy and self-therapy interventions prompted the authors to focus on the analgesic and myorelaxant use of massage, post-isometric muscle relaxation (PIR) and therapeutic exercise in TMD patients. OBJECTIVES: To evaluate the effectiveness of soft tissue therapy and therapeutic exercises in female patients with pain, increased masseter muscle tension and limited mandibular mobility. MATERIAL AND METHODS: The study was conducted on a group of 82 women (G1) with the Ib disorder diagnosed in DC/TMD (Ib-myofascial pain with restricted mobility). The control group (G2) consisted of 104 women without diagnosed TMDs (normal reference values for TMJ ROM and masseter muscle sEMG bioelectric activity). Diagnostic procedures were performed in both groups (sEMG of the masseter muscles at baseline and during exercise, measurement of TMJ mobility, assessment of pain intensity-NRS scale). The G1 group was randomly divided into 3 therapeutic groups in which the therapy was carried out for 10 days: therapeutic exercises (TE), manual therapy - massage and therapeutic exercises (MTM_TE), manual therapy - PIR and therapeutic exercises (MTPIR_TE). Each time after therapy, the intensity of pain and TMJ mobility were assessed. Sealed, opaque envelopes were used for randomization. After 5 and 10 days of therapy, bilateral sEMG signals of the masseter muscles were acquired. RESULTS: Massage, PIR and self-therapy led to a decrease in sEMG at rest as well as in exercise. After day 6 of therapy, the groups obtained a significant difference (p = 0.0001). Each of the proposed forms of therapy showed a minimal clinically significant difference (MID) in the sEMG parameter at the endpoint, with the most considerable difference in the MTM_TE group. The forms of MT used were effective in reducing the patients' pain intensity; however, a significant difference between therapies occurred after 4 treatments (p = 0.0001). Analyzing the MID between methods, it was observed that self-therapy had an analgesic effect only after 8 treatments, while PIR after 3 and massage after 1 treatment. After day 7, the mean pain score in the MTM_TE group was 0.889 and in the TMPIR_TE group was 3.44 on the NRS scale. In terms of MMO, a significant difference was obtained between monotherapy and each form of TM, i.e. massage (p = 0.0001) and PIR (p = 0.0001). Analyzing mandibular lateral movements, the authors got a significant difference in the proposed MT forms, of which massage treatments exceeded the effectiveness of PIR. CONCLUSIONS: Soft tissue manual therapy and therapeutic exercise are simple and safe interventions that can potentially benefit patients with myogenic TMDs, with massage showing better analgesic effects than PIR.

Effectiveness of various methods of manual scar therapy.

BACKGROUND: The skin is a protective barrier of the body against external factors, and its damage leads to a loss of integrity. Normal wound healing results in a correct, flat, bright, and flexible scar. Initial skin damage and patient specific factors in wound healing contribute that many of these scars may progress into widespread or pathologic hypertrophic and keloid scars. The changes in cosmetic appearance, continuing pain, and loss of movement due to contracture or adhesion and persistent pruritis can significantly affect an individual's quality of life and psychological recovery post injury. Many different treatment methods can reduce the trauma and surgical scars. Manual scar treatment includes various techniques of therapy. The most effectiveness is a combined therapy, which has a multidirectional impact. Clinical observations show an effectiveness of manual scar therapy. MATERIAL AND METHODS: The aim of this work was to evaluate effectiveness of the scar manual therapy combined with complementary methods on the postoperative scars. Treatment protocol included two therapies during 30 min per week for 8 weeks. Therapy included manual scar manipulation, massage, cupping, dry needling, and taping. RESULTS: Treatment had a significant positive effect to influence pain, pigmentation, pliability, pruritus, surface area, and scar stiffness. Improvement of skin parameters (scar elasticity, thickness, regularity, color) was also noticed. CONCLUSION: To investigate the most effective manual therapy strategy, further studies are needed, evaluating comparisons of different individual and combined scar therapy modalities.

Comparison of the effectiveness of instrument-assisted soft tissue mobilization and extracorporeal shock wave therapy in myofascial pain syndrome.

Background/aim: To compare the effectiveness of instrument-assisted soft tissue mobilization (IASTM) and extracorporeal shock wave therapy (ESWT) used in myofascial pain syndrome (MPS) and to determine whether they are superior to conservative treatment (CT). Materials and methods: A total of 42 female patients (aged 18-60 years) diagnosed with MPS were enrolled and randomly assigned to either the CT (n = 14), CT+IASTM (n = 14), or CT+ESWT group (n = 14). All of the groups received treatment for 3 weeks (CT: 5 sessions per week, 15 sessions in total, ESWT and IASTM: 2 sessions per week, 6 sessions in total). Neck stretching exercises were given to all of the patients as a home program. The pain intensity of the patients was determined using the visual analog scale (VAS). The pressure pain threshold (PPT) was measured with an algometer. Cervical joint range of motion (ROM) was measured with a cervical ROM (CROM) device. Pain, cervical disability, quality of life, and sleep disturbances were evaluated with the Neck Outcome Score (NOOS). Depression and anxiety parameters were evaluated with the Hospital Anxiety and Depression Scale (HADS). Evaluations were made before treatment and 3 days after the last treatment session. Results: The CT+IASTM group was more successful than the other groups in terms of pain intensity, PPT, and improvements in the ROM parameters (p < 0.05). No significant difference was found between the NOOS and HADS scores of the groups when the posttreatment changes were compared to pretreatment (p > 0.05). Conclusions: All 3 of these treatments can be used to alleviate the negative effects of MPS. IASTM treatment can be preferred primarily in the creation of combined treatment programs for patients with ROM limitations and low PPTs.

Multisensory Stimulation and Soft Tissue Therapy on Pain and Neurodevelopment Among Preterm Neonates.

PURPOSE: To determine the combined effects of multisensory stimulation (MSS) and soft tissue therapy (STT) in managing procedural pain and promoting neurodevelopment in neonates undergoing repetitive painful procedures during their neonatal intensive care unit (NICU) stay. METHODS: Total of 104 preterm neonates admitted in NICU will be recruited for this trial. The intervention will be given for 5 consecutive days to both the groups. Experimental group will receive both MSS and STT; control group will receive routine NICU care. The premature infant pain profile and Neonatal Pain, Agitation, and Sedation Scale will be used for assessing procedural pain, and Infant Neurological International Battery and Premie-Neuro will be used for assessing neurodevelopmental maturity. Relevant parametric or nonparametric test will be used to analyze the data for all outcomes. DISCUSSION: This is a study protocol analyzing the combined effects of nonpharmacological interventions (MSS and STT) in preterm neonates.

Gingival Recession Treatment with the Use of Xenogeneic Matrix: Optimization of Patient-Centered Outcomes by the Digital Soft Tissue Design

Abstract Objective: To evaluate the impact of the originally-developed approach aimed at pre-treatment graphical modelling of soft-tissue changes (digital soft tissue design) for the optimization of patient-centered outcomes after Class I and Class II single gingival recessions treatment with the use of a xenogeneic dermal matrix. Material and Methods: Patients enrolled in the study group received single gingival recession treatment via CAF+XDM method supported by pre-treatment graphical modelling of potential soft-tissue changes (digital soft tissue design), while patients enrolled in the control group received single gingival recession treatment via CAF+CTG method with no pre-treatment graphical modeling of gingival level changes. Patient-centered outcomes were measured by visual analogue scale, OHIP-14, and Mahajan's scales. Results: Realization of pre-treatment graphical modelling of soft-tissue changes supported the achievement of better patient-centered outcomes, such as root coverage (p<0.05), surgical phase (p<0.05), post-surgical phase (p<0.05), cost-effectiveness (p<0.05) and diagnostics and patient-orientation (p<0.05) based on patient's personal perception grades. Conclusion: Patient-centered results were found to be more successful within the group using the xenogeneic type of graft accompanied with the implementation of pre-treatment graphical modeling of soft tissue changes, which helped to balance patients' pre-operative expectations and post-operative satisfaction with the received results, reduce post-operative morbidity and improve oral health-related quality of life (AU).

Concentrados plaquetarios para regeneración y tratamiento de tejidos duros y blandos / Platelet concentrates for regeneration and treatment of the hard and soft tissues

Debido a la alta frecuencia de las recesiones periodontales y sus repercusiones, de comparar los efectos de los diferentes derivados plaquetarios utilizados en el tratamiento de lesiones en tejidos blandos y duros orales. Se realizó una búsqueda en Pubmed/ Medline, EMBASE, el Registro de Ensayos del Cochrane Oral Health Group, Lilacs de ensayos clínicos que utilicen concentrados plaquetarios para el tratamiento de defectos periodontales y periimplantarios en comparación con los tratamientos convencionales. Los principales resultados observados no mostraron diferencias significativas en ninguna de las siguientes variables: profundidad de sondaje, nivel de inserción clínico, recubrimiento radicular mediante colgajo de avance coronal y grosor de encía queratinizada. La única variable estudiada en la que se encontraron diferencias significativas fue en la realización de un colgajo de acceso agregando concentrados plaquetarios y sin ellos. Podemos concluir en este estudio que los derivados plaquetarios como el plasma rico en plaquetas (PRP), plasma rico en fibrina (PRF) y el plasma rico en fibrina y leucocitos (L-PRF) pueden ser beneficiosos en el tratamiento y regeneración de tejidos blandos y duros periodontales y periimplantarios. No obstante, se necesita más investigación para analizar detalladamente el comportamiento de estos derivados sanguíneos. (AU)

This study was put forward as a result of the number and consequences of periodontal recessions, this review aims to compare the effects of different types of platelet concentrates used to treat hard and soft oral tissue defects. In order to do so, clinical trials were researched based on the usage of platelet concentrates, compared with conventional treatments were searched in PubMed/Medline, EMBASE, Cochrane Oral Health Group, and Lilacs. Within the main outcomes, there were not found remarkable differences in any of the following factors: probing depth, clinical attachment level, root coverage, coronal advance fl ap, keratinized gingival width. There was only signifi cant distinction on the studies that compared the usage of an access fl ap variable with and without platelet concentrates. To sum up, seems to be benefi cial the addition of platelet rich plasma (PRP), platelet rich fibrin (PRF) and leucocyte platelet rich fibrin (L-PRF) to the treatment when dealing with periodontal and periimplant defects. Nevertheless, further investigations and studies are needed in order to be able to analyze in detail the behavior of these blood products. (AU)

Management of surgical soft tissue defects of the lower extremities.

Management of post-operative soft-tissue defects on the lower legs is challenging owing to arterial and venous insufficiency, poor skin quality including epidermal and dermal atrophy, insufficient tissue laxity, and increased risk of infection. This paper highlights the management of post-operative soft-tissue defects on the lower extremity that cannot be closed primarily or by reconstruction with a local flap. A systematic review of the literature was performed using the National Library of Medicine (NLM) PubMed online database. Articles were included if they reported the management of post-operative lower extremity soft-tissue defects with secondary intention healing, full-thickness skin graft, split-thickness skin grafts, or skin substitutes. Sixty-three articles were included for analysis. There are several options for managing surgical defects on the lower legs and the method chosen should depend on various factors, including the quality of the skin, vascularity and size of the defect, medical history of the patient, and the experience of the surgeon.

ACR appropriateness criteria imaging of mediastinal masses

Mediastinal masses can present with symptoms, signs, and syndromes or incidentally. Selecting the appropriate diagnostic imaging study for mediastinal mass evaluation requires awareness of the strengths and weaknesses of the various imaging modalities with regard to tissue characterization, soft tissue contrast, and surveillance. This publication expounds on the differences between chest radiography, CT, PET/CT, ultrasound, and MRI in terms of their ability to decipher and surveil mediastinal masses. Making the optimal imaging choice can yield diagnostic specificity, avert unnecessary biopsy and surgery, guide the interventionist when necessary, and serve as a means of surveillance for probably benign, but indeterminate mediastinal masses. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Comparative efficacy of interventions for reducing symptoms of depression in people with dementia: systematic review and network meta-analysis.

OBJECTIVE: To describe the comparative efficacy of drug and non-drug interventions for reducing symptoms of depression in people with dementia who experience depression as a neuropsychiatric symptom of dementia or have a diagnosis of a major depressive disorder. DESIGN: Systematic review and meta-analysis. DATA SOURCES: Medline, Embase, the Cochrane Library, CINAHL, PsycINFO, and grey literature between inception and 15 October 2020. ELIGIBILITY CRITERIA FOR STUDY SELECTION: Randomised trials comparing drug or non-drug interventions with usual care or any other intervention targeting symptoms of depression in people with dementia. MAIN OUTCOME MEASURES: Pairs of reviewers screened studies, abstracted aggregate level data, and appraised risk of bias with the Cochrane risk of bias tool, which facilitated the derivation of standardised mean differences and back transformed mean differences (on the Cornell scale for depression in dementia) from bayesian random effects network meta-analyses and pairwise meta-analyses. RESULTS: Of 22 138 citations screened, 256 studies (28 483 people with dementia) were included. Missing data posed the greatest risk to review findings. In the network meta-analysis of studies including people with dementia without a diagnosis of a major depressive disorder who were experiencing symptoms of depression (213 studies; 25 177 people with dementia; between study variance 0.23), seven interventions were associated with a greater reduction in symptoms of depression compared with usual care: cognitive stimulation (mean difference -2.93, 95% credible interval -4.35 to -1.52), cognitive stimulation combined with a cholinesterase inhibitor (-11.39, -18.38 to -3.93), massage and touch therapy (-9.03, -12.28 to -5.88), multidisciplinary care (-1.98, -3.80 to -0.16), occupational therapy (-2.59, -4.70 to -0.40), exercise combined with social interaction and cognitive stimulation (-12.37, -19.01 to -5.36), and reminiscence therapy (-2.30, -3.68 to -0.93). Except for massage and touch therapy, cognitive stimulation combined with a cholinesterase inhibitor, and cognitive stimulation combined with exercise and social interaction, which were more efficacious than some drug interventions, no statistically significant difference was found in the comparative efficacy of drug and non-drug interventions for reducing symptoms of depression in people with dementia without a diagnosis of a major depressive disorder. Clinical and methodological heterogeneity precluded network meta-analysis of studies comparing the efficacy of interventions specifically for reducing symptoms of depression in people with dementia and a major depressive disorder (22 studies; 1829 patients). CONCLUSIONS: In this systematic review, non-drug interventions were found to be more efficacious than drug interventions for reducing symptoms of depression in people with dementia without a major depressive disorder. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42017050130.

Effects of Diacutaneous Fibrolysis on Mechanosensitivity, Disability, and Nerve Conduction Studies in Mild to Moderate Carpal Tunnel Syndrome: Secondary Analysis of a Randomized Controlled Trial.

OBJECTIVE: People diagnosed with carpal tunnel syndrome (CTS) have fibrosis between the soft, connective, and neural tissues that could worsen the compression of the median nerve. The diacutaneous fibrolysis (DF) technique may release tissue adhesions and increase the mobility of connective tissues. The purpose of this study was to compare the outcomes of DF in people with mild to moderate CTS on mechanosensitivity, disability, and nerve conduction studies. METHODS: This was a secondary analysis of a double-blinded, randomized, placebo-controlled trial. Patients were recruited between April and September 2016 from the Department of Neurophysiology at the Hospital Miguel Servet, Zaragoza, Spain. Thirty-nine people (52 wrists) diagnosed with mild to moderate CTS were included. Participants were randomly assigned to either the DF group (n = 26) or the sham group (n = 26). Both groups received 5 therapy sessions, 2 sessions per week. Mechanosensitivity with the Upper Limb Neurodynamic Test 1, symptom severity and functional status with the Boston Carpal Tunnel Questionnaire, and median nerve sensory conduction velocity with nerve conduction studies were the outcomes measured. Assessments were recorded at baseline and after the intervention. RESULTS: The DF group showed significant improvements in the following: mechanosensitivity, with 28.46 degrees of elbow extension range of motion (95% CI = 19.2-37.7); an increase of 1.0 point (95% CI = 0.7-1.4) for the Boston Carpal Tunnel Questionnaire symptom severity and functional status score; and sensory conduction velocity of median nerve, which improved to 5.8 m/s (95% CI = 2.5-9.2). CONCLUSION: Participants with mild to moderate CTS experienced improvements in symptom severity, functional status, mechanosensitivity, and nerve conduction studies after 5 sessions of DF. IMPACT: This study provides evidence of an approach based on soft and connective tissues around the median nerve in patients with CTS.

Background Limbs soft tissue sarcomas have an incidence of 4.7 cases per 100,000 inhabitants and their surgical management has a high rate of morbidity and mortality due to bleeding. Use of ultrasonic vessel sealing is a novel technique often required. The aim of the study is to determine whether the intraoperative and postoperative results can be improve with the use of ultrasonic vessel sealing systems when surgeons are performing resection surgery of soft tissue sarcomas. Methods A longitudinal cohort was conducted between May 2017 and December 2018, including all patients undergoing resection of soft tissue sarcomas using ultrasonic vessel sealing technology that presented intraoperative and postoperative complications. The variables of age, sex, municipality, neighborhood, occupation, preoperative hemoglobin, intraoperative bleeding, hemovac drainage, postsurgical hemoglobin, seroma, hematoma, need for blood transfusion, and major complications were recorded. Data were analyzed using Shapiro Wilk or Kolmogorov Smirnov for descriptive statistics. Hypothesis tests to compare the occurrence of certain characteristics by stage or severity of the tumor pathology were performed using the Chi2 test or Fisher's test in qualitative variables, while the quantitative ones with t Student or Mann Whitney, a value of p<0.05 it was considered statistically significant. Results 32 patients were included in the study: 13 women and 19 men; the main types of sarcomas found were spindle cell sarcoma in 11 cases and liposarcoma in 5 cases. A median hemoglobin difference of −1.85g/dL was found. The use of the ultrasonic bipolar vessel sealing system showed a 71% success rate for surgeries; complications occurred in 12% of patients. Discussion Ultrasonic vessel sealing system is a valid alternative that benefits limbs soft tissue sarcomas resection patient surgery by reducing surgery time and improving safer hemostasis. Further randomized controlled studies should be preformed.

3D CT Soft Tissue Craniofacial Analysis and Lip Morphology

ABSTRACT Objctive: To assess the soft tissue characteristics of Bangladeshi adults to formulate soft tissue 3D CT standards using Holdaway's (HA) and lip morphology (LM) analyses. Another aim of this study was to assess the gender dimorphism of Bangladeshi population. Material and Methods: One hundred and seventeen (Eighty-five men and Thirty-two women) Bangladeshi adults have obtained their computed tomography (CT) scan at the Radiology Department for normal diagnosis. Craniofacial deformities were undetected in all cases. The CT images were prepared by a 3D imaging programming software (Mimics 11.02 Materialise). Parameters from the identified landmark points were measured in 3D through this software. Results: Upper lip thickness (ULT) (vermillion UL-A point) measurement was significant in HA and in LM analyses, upper lip protrusion (ULP) (Ls to Sn-SPog) measurement has demonstrated significant difference among both genders, where p-value was less than 0.05. Mean measurements of Bangladeshi adults were relatively comparable except the face convexity (FC) when compared with the HA cephalometric soft tissue values. Conclusion: By using HA and LM analyses, 3D CT soft tissue standards were established for Bangladeshi adults. Measurements for all parameters have remained equivalent with the HA standard data apart from the FC measurement. This consequently may demonstrate that the Bangladeshi population retains a convex shape with a slight protrusive lip or retruded chin.

Utilización de láser diodo en tejidos blandos: reporte de 3 casos / Use of diode laser in soft tissue: report of 3 cases

Existen diversas condiciones anatómicas o alteraciones mucogingivales que pueden afectar tanto el normal funcionamiento como la estética gingival de piezas dentarias e implantes dentales. Si bien los tratamientos de estas condiciones se han realizado tradicionalmente con bisturí, el desarrollo tecnológico ha permitido que actualmente se pueden realizar con láser. Existen diferentes tipos de láser, siendo el diodo uno de los más utilizados debido a su menor tamaño, portabilidad, fácil configuración y menor costo. El láser ha adquirido mayor popularidad en cirugías de tejido blando dado sus múltiples beneficios: menor tiempo operatorio, control del sangrado y de la hemostasia, reducción de la cantidad de anestesia, posibilidad de no requerir suturas y minimización del dolor e inflamación postquirúrgica. El propósito de este trabajo es presentar la resolución de tres casos clínicos a los cuales se les realizaron los procedimientos de frenectomía labial, remoción de melanosis gingival y resección de fibroma irritativo mediante el uso de láser diodo. Para desarrollar todos los procedimientos se utilizó un equipo de láser diodo de 940 nm (Biolase®, USA) con una potencia que varió entre 2 y 2.5 W en modo continuo utilizando una pieza quirúrgica con una punta de 300 µm (E 3-4), la que fue activada antes de empezar. Posterior a la cirugía se bioestimuló para disminuir el dolor y edema postoperatorio utilizando la punta de dolor a 4 W por 30 segundos a una distancia de 1 cm directo en la zona intervenida a todos los casos. La conclusión arroja que en todos los casos, el láser de diodo permitió un resultado exitoso. El procedimiento fue seguro, la técnica fue sencilla y de tiempo clínico reducido. El postoperatorio ocurrió con ausencia de dolor o molestias, generando una mayor satisfacción del paciente. Cabe señalar que la técnica depende de la habilidad del profesional que la realiza.

There are various anatomical conditions or mucogingival alterations that can affect the normal functioning and the gingival aesthetics of teeth and dental implants. Although the treatments of these conditions have been traditionally performed with a scalpel, technological development has allowed that they can be now performed with lasers. There are different types of lasers, being the diode one of the most used due to its smaller size, portability, easy configuration, and lower cost. The laser has become more popular in soft tissue surgeries due to its multiple benefits: shorter operating time, control of bleeding and hemostasis, reduction in the amount of anesthesia, possibility of not requiring sutures, and minimization of post-surgical pain and inflammation. The purpose of this work is to present the resolution of three clinical cases which underwent labial frenectomy procedures, removal of gingival melanosis and resection of irritative fibroma using diode laser. To develop all the procedures, a 940 nm diode laser equipment (Biolase®, USA) was used with a power that varied between 2 and 2.5 W in continuous mode, using a 300 µm tip (E 3-4), which was activated before starting. After surgery, biostimulation was carried out to reduce postoperative pain and edema using the pain tip at 4 W for 30 seconds at a distance of 1 cm directly in the operated area in all cases. In all cases, the diode laser allowed a successful result. The procedure was safe, the technique was simple, and the clinical time was short. The postoperative period occurred with the absence of pain or discomfort, generating greater patient satisfaction. It should be noted that the technique depends on the skill of the professional who performs it.

Comparison of the Graston Technique® With Instrument-Assisted Soft Tissue Mobilization for Increasing Dorsiflexion Range of Motion.

CONTEXT: Limited dorsiflexion (DF) range of motion (ROM) is commonly observed in both the athletic and general populations and is a predisposing factor for lower extremity injury. Graston Technique® (GT) is a form of instrument-assisted soft tissue mobilization (IASTM), used commonly to increase ROM. Evidence of the long-term effects of GT on ROM is lacking, particularly comparing the full GT protocol versus IASTM alone. OBJECTIVE: To evaluate the effectiveness of 6 sessions of the GT or IASTM compared with a control (CON) group for increasing closed-chain DF ROM. DESIGN: Cohort design with randomization. SETTING: Athletic training clinic. PATIENTS OR OTHER PARTICIPANTS: A total of 23 physically active participants (37 limbs) with <34° of DF. Participants' limbs were randomly allocated to the GT, IASTM, or CON group. INTERVENTION: Participants' closed-chain DF ROM (standing and kneeling) were assessed at baseline and 24-48 hours following their sixth treatment. Participants in the CON group were measured at baseline and 3 weeks later. The intervention groups received 6 treatments during a 3-week period, whereas the CON group received no treatment. The GT group received a warm-up, instrument application, stretching, and strengthening of the triceps surae. The IASTM group received a warm-up and instrument application. MAIN OUTCOME MEASURES: Closed-chain DF was assessed with a digital inclinometer in standing and kneeling. RESULTS: A significant difference between groups was found in the standing position (P = .03) but not in kneeling (P = .15). Post hoc testing showed significant improvements in DF in standing following the GT compared with the control (P = .02). CONCLUSIONS: The GT significantly increases ankle DF following 6 treatments in participants with DF ROM deficits; however, no differences were found between GT and IASTM. The GT may be an effective intervention for clinicians to consider when treating patients with DF deficits.

Vacuum myofascial therapy device for non-specific neck pain. A single blind randomized clinical trial.

OBJECTIVES: This study aimed to investigate the efficacy of a vacuum myofascial therapy device (VT) for improving pressure pain thresholds (PPTs), range of motion (ROM), neck pain-related disability, pain, and quality of life in patients with non-specific neck pain. METHODS: A randomized controlled trial in which thirty-eight participants with non-specific neck pain (NP) were randomly assigned to either an experimental (VT) or a comparison physical therapy program (PTP) group. The VT group (n = 19) received five sessions of treatment with a vacuum myofascial therapy device while the PTP group (n = 19) received five sessions of massage, ultrasound therapy (US), and transcutaneous electric nerve stimulation (TENS) over two weeks. The outcome measures were the numerical pain rating scale (NPRS), range of motion, quality of life (SF-12), neck disability Index (NDI), and PPTs at the end of treatment and at one-month follow-up. RESULTS: Although both groups experienced improvements in pain, neck disability, range of motion, and pressure pain, these only were statistically significant in the VT group. At one-month follow-up, the VT group still showed improvements in pain, neck disability, and range of motion. DISCUSSION: Vacuum myofascial therapy applied with a device offers similar results to other vacuum-based techniques such as cupping therapy. Moreover, in this device the parameters are digitally controlled, which allows for the precise reproduction of treatment.
