Acute Effects of Local High-Frequency Percussive Massage on Deep Fascial and Muscular Stiffness and Joint Range of Motion in Young Adult Men.

BACKGROUND: Local high-frequency percussive (HFP) massage has recently found widespread application in physical therapy. Although HFP massage reportedly improves range of motion (ROM), the mechanism underlying its action has not yet been proven. This study aimed to clarify whether a 5-minute percussive massage regimen affects muscular or connective tissues, such as the deep fascia and deep intermuscular fascia and the change in joint ROM. METHOD: The study sample was calculated using G*Power analysis program, and this study enrolled 15 healthy men who underwent 5-minute HFP massage to the medial gastrocnemius muscle. Shear-wave elastography was used to measure tissue stiffness in the deep fascia, muscle, and deep intermuscular fascia through shear-wave velocity as well as the ROM of the volunteers' ankle joint dorsiflexion before and after the HFP massage. A value of P < .05 was used to declare statistical significance, and post hoc was used to calculate the effect size using G*Power. RESULTS: Shear-wave velocity revealed a significant change in the deep fascia (P = .003; shear-wave velocity: -0.7 m/s) and significant increase in ROM of ankle dorsiflexion (P = .002; increase in ROM: 3.0°) after 5 minutes of HFP massage. However, the muscle and deep intermuscular fascia did not exhibit any significant changes. CONCLUSIONS: HFP massage for 5 minutes modified the stiffness of the deep fascia and concurrently improved the ankle joint-dorsiflexion ROM. This method can be used as an intervention to decrease stiffness of the deep fascia and increase the ROM efficiently.

Correlation between jingjin injury and wulao and the relevant prevention and treatment strategies. / 经筋损伤与"五劳"çš„ç›¸å ³æ€§åŠé˜²æ²»ç­–ç•¥.

The paper explores the correlation between jingjin (muscle regions of meridians, sinews/fascia) injury and wulao (five types of exhaustion) and the relevant prevention and treatment strategies, and determines the internal mechanism of the disease so as to provide the ideas for prevention and treatment of jingjin injury. Wulao may result in jingjin injury not only through the damages of blood, qi, muscles, bones and tendons indirectly, but also through the damage of soft tissues directly. The great attention should be paid to preventing from jingjin injury, especially wulao, due to which, the appropriate combination of the static and the dynamic skills is emphasized in the way of physical exercise. When the injury occurred, the conditions of the whole body should be analyzed comprehensively and the local affected regions be concentrated simultaneously in treatment. For the indirect injury, the holistic idea should be the basis of regulating five zang organs and restoring the physiological functions of blood, qi, muscles, bones and sinews so as to adjust jingjin. Regarding the direct injury, the staging regimen for the local treatment is considered to harmonize qi and blood and balance sinews and bones. When the injury has been cured, the physical exercise is recommended to strengthen sinews and bones according to individual conditions to prevent from recurrence.

Ultrasound imaging and Fascial Manipulation®: 'Adding a twist' on the ankle retinacula.

BACKGROUND: Retinacula of the ankle are thickening of the deep fascia of the leg (crural fascia) and foot i.e. inseparable structures. Recent studies report their crucial role in functional stability and proprioception of the ankle. CASE PRESENTATION: A 38-yr-old Caucasian man - with a history of lateral malleolus fracture 12 years ago, obesity and right ankle osteoarthritis - was referred to a physiatrist for a right ankle pain that had significantly worsened over the last year. During walking, the patient experienced stinging pain in the area of tibialis anterior and peroneus tertius muscles, and the superior extensor retinaculum. Magnetic resonance imaging and ultrasonography showed clear thicknening (2.05 mm) of the oblique superomedial band of the inferior extensor retinaculum. Sonopalpation was performed to precisely evaluate/confirm the site of maximum pain. Foot function index (FFI) score was 42. RESULTS: Subsequently, the patient was prescribed fascial manipulation, and he had clinical improvement after the first session (FFI: 21). At 1-month follow-up, the patient was still asymptomatic without any functional limitation (FFI: 24). US imaging confirmed the decreased thickness of the oblique superomedial band of the extensor retinaculum (1.35 mm). CONCLUSION: Fascial Manipulation® appears to be a useful tool to reduce thickness, stiffness, and pain in this case as displayed by the ultrasound Imaging.

Factors to consider for fascial plane blocks' success in acute and chronic pain management.

The outcome of fascial plane blocks (FPBs) has a certain variability that may depend on many factors, which can be divided into three main categories: operator-related, patient-related and drug-related. Operator-related factors include personal skills, choice of needle and injection modalities. Patient variables include anthropometric features, the type of targeted fascia, anatomical variants, patient positioning, muscle tone and breathing. Ultimately, efficacy, onset, and duration of fascial blocks may be affected by characteristics of the injected solution, including the type of local anesthetic, volume, concentration, pH, temperature and the use of adjuvants. In this article, we investigated all the factors that may influence the outcome of FPBs from a generic perspective, without focusing on any specific technique. Also, we provided suggestions to optimize techniques for everyday practitioners and insights to researchers for future studies.

A new perspective on tissue gliding dysfunction bordered by deep fascia as an indicator of delayed onset muscle soreness: A case report.

INTRODUCTION: The deep fascia, especially its thickness and stiffness, plays an important role in the mechanism of delayed onset muscle soreness (DOMS). Here, we present a patient with DOMS associated with a tissue gliding dysfunction bordered by the deep fascia. CASE PRESENTATION: A 25-year-old woman developed DOMS of the left upper arm. We confirmed the tissue gliding dysfunction during manual skin traction by ultrasound imaging and treated with acupuncture aimed at stimulating the deep fascia. Tissue gliding between subcutaneous and muscle tissues bordered by the deep fascia was analyzed qualitatively and quantitatively, i.e., phases and distance of displacement. At the initial examination, the tissue gliding phases were in the same direction synchronously and the distance of displacement was 0.66mm. After the DOMS symptoms improved with direct acupuncture to the deep fascia, the phases changed independently in opposite directions and their displacement was 7.04mm. CONCLUSIONS: In this patient, tissue gliding played an important role in the symptoms of DOMS. This case report focusing on tissue gliding provides a new perspective on understanding the pathogenesis of DOMS.

Quantitative Tension on the Abdominal Wall in Posterior Components Separation With Transversus Abdominis Release.

Importance: Posterior components separation (PCS) is a commonly used myofascial release technique in ventral hernia repairs. The contribution of each release with anterior and posterior fascial advancement has not yet been characterized in patients with ventral hernias. Objective: To quantitatively assess the changes in tension on the anterior and posterior fascial elements of the abdominal wall during PCS to inform surgeons regarding the technical contribution of each step with those changes, which may help to guide intraoperative decision-making. Design, Setting, and Participants: This case series enrolled patients from December 2, 2021, to August 2, 2022, and was conducted at the Cleveland Clinic Center for Abdominal Core Health. The participants included adult patients with European Hernia Society classification M1 to M5 ventral hernias undergoing abdominal wall reconstruction with PCS. Intervention: A proprietary, sterilizable tensiometer measured the force needed to bring the fascial edge of the abdominal wall to the midline after each step of a PCS (retrorectus dissection, division of the posterior lamella of the internal oblique aponeurosis, and transversus abdominis muscle release [TAR]). Main Outcome: The primary study outcome was the percentage change in tension on the anterior and posterior fascia associated with each step of PCS with TAR. Results: The study included 100 patients (median [IQR] age, 60 [54-68] years; 52 [52%] male). The median (IQR) hernia width was 13.0 (10.0-15.2) cm. After complete PCS, the mean (SD) percentage changes in tension on the anterior and posterior fascia were -53.27% (0.53%) and -98.47% (0.08%), respectively. Of the total change in anterior fascial tension, retrorectus dissection was associated with a mean (SD) percentage change of -82.56% (0.68%), incision of the posterior lamella of the internal oblique with a change of -17.67% (0.41%), and TAR with no change. Of the total change in posterior fascial tension, retrorectus dissection was associated with a mean (SD) percentage change of -3.04% (2.42%), incision of the posterior lamella of the internal oblique with a change of -58.78% (0.39%), and TAR with a change of -38.17% (0.39%). Conclusions and Relevance: In this case series, retrorectus dissection but not TAR was associated with reduced tension on the anterior fascia, suggesting that it should be performed if anterior fascial advancement is needed. Dividing the posterior lamella of the internal oblique aponeurosis and TAR was associated with reduced tension on the posterior fascia, suggesting that it should be performed for posterior fascial advancement.

[Professor LI De-hua's experience in treating facial nerve injury after total parotidectomy with blade needle based on jingjin theory].

The paper summarizes the academic thought and clinical experience of professor LI De-hua in treatment of facial nerve injury after total parotidectomy with blade needle based on jingjin (muscle region of meridian, sinew/fascia) theory. This disease is located at muscle regions of hand-/foot-three yang meridians; and the sinew/fascia adhesion is its basic pathogenesis, manifested by "transversely-distributed collaterals" and "knotted tendons". In treatment, the knotted tendons are taken as the points. Using the relaxation technique of blade needle, the lesions of sinews/fascia are dissected and removed to release the stimulation or compression to the nerves and vessels so that the normal function of sinews/fascia can be restored.

[Exploration of the thinking and methods in treatment of cancer pain with acupuncture and moxibustion on the base of the fascia theory].

There is a commonality between jingjin (muscle region of meridian) and the fascial network for coordinating the balance in the body. The occurrence and the progression of tumor may disrupt the overall coordination between the fascial network and jingjin directly or indirectly, thereby, the impairment of this coordination may result in cancer pain. Rooted on the theory of overall balance of the fascial network, and combined with understanding of pain in jingjin theory, professor HUANG Jin-chang emphasizes the importance of "relaxing the knot" in treatment of cancer pain. It is recommended to select the fascia reaction point as the target point, in accordance with the principle of balance adjustment and apply various acupuncture and moxibustion therapies, such as Fu's subcutaneous needling, small-needle scalpel therapy, fire needling, and moxibustion.

Thoracolumbar fascia mobility and chronic low back pain: Phase 1 of a pilot and feasibility study assessing repeated measures and the influence of paraspinal muscle contraction.

BACKGROUND: Differential movement, or shear strain (SS), between layers of thoracolumbar fascia is reduced with chronic low back pain. To provide a foundation for clinical research involving SS, this study assessed temporal stability and the effect of paraspinal muscle contraction on SS in persons with chronic low back pain. METHODS: We used ultrasound imaging to measure SS in adults self-reporting low back pain ≥1 year. Images were obtained by placing a transducer 2-3 cm lateral to L2-3 with participants lying prone and relaxed on a table moving the lower extremities downward 15°, for 5 cycles at 0.5 Hz. To assess paraspinal muscle contraction effects, participants raised the head slightly from the table. SS was calculated using 2 computational methods. Method 1 averaged the maximum SS from each side during the third cycle. Method 2 used the maximum SS from any cycle (2-4) on each side, prior to averaging. SS was also assessed after a 4-week no manual therapy period. RESULTS: Of 30 participants (n = 14 female), mean age was 40 years; mean BMI 30.1. Mean (SE) SS in females with paraspinal muscle contraction was 66% (7.4) (method 1) and 78% (7.8) (method 2); 54% (6.9) (method 1) and 67% (7.3) (method 2) in males. With muscles relaxed, mean SS in females was 77% (7.6) (method 1) or 87% (6.8) (method 2); 63% (7.1) (method 1) and 78% (6.4) (method 2) in males. Mean SS decreased 8-13% in females and 7-13% in males after 4-weeks CONCLUSION: Mean SS in females was higher than males at each timepoint. Paraspinal muscle contraction temporarily reduced SS. Over a 4-week no-treatment period, mean SS (with paraspinal muscles relaxed) decreased. Methods less likely to induce muscle guarding and enabling assessment with broader populations are needed.

Acute effects of thoracolumbar fascia release techniques on range of motion, proprioception, and muscular endurance in healthy young adults.

PURPOSE: This study investigates the acute effects of Graston and myofascial release on thoracolumbar fascia (TLF) on lumbar range of motion (ROM), lumbar and cervical proprioception, and trunk muscle endurance in healthy young adults. METHOD: Twenty-four healthy young individuals were included in the study. Individuals were randomly divided into two groups as Graston technique (GT) (n = 12) and myofascial release (MFR) (n = 12). GT group received a fascial treatment with a graston instrument and the MFR group (n = 12) received manual myofascial treatment. Both techniques were applied for 10 min and as a single session. Lumbar ROM (goniometer), lumbar proprioception (digital inclinometer), cervical proprioception (CROM device), and trunk muscle endurance (with McGill Endurance Test) were evaluated before and after treatment. RESULTS: Age, gender and body mass index of individuals in both groups were similar (p > 0.05). In both GT and MFR groups, an increase in ROM in the flexion direction (p < 0.05) and a decrease in the angle of deviation in proprioception in the flexion direction were determined (p < 0.05). Neither technique had a significant effect on cervical proprioception and trunk muscle endurance (p > 0.05). In addition, no difference was found between the effectiveness of Graston and myofascial release (p > 0.05). CONCLUSION: This study showed that Graston and myofascial release applied to TLF in healthy young adults effectively improve lumbar ROM and proprioception in the acute period. Considering these results, both Graston and myofascial release can be used to provide elasticity of TLF and improve proprioceptive return.

Concurrent validity of palpation and musculoskeletal ultrasound in evaluating the fascia of individuals with and without myofascial pain syndrome.

BACKGROUND AND PURPOSE: Palpation evaluates the fascia, a three-dimensional web of connective tissues. We propose altered fascia system displacement in patients with myofascial pain syndrome. This study determined the concurrent validity of palpation and musculoskeletal ultrasound (MSUS) videos played on Windows Media Player 10 (WMP) when evaluating the direction of the fascia system's displacement at the end of the cervical active range of motion (AROM). METHODS: This cross-sectional study used palpation as index test and MSUS videos on WMP as reference test. First, three physical therapists palpated right and left shoulders for each cervical AROM. Second, during cervical AROM, PT-Sonographer recorded the fascia system displacement. Third, using the WMP, the physical therapists evaluated the direction of skin, superficial and deep fascia displacements at the end of cervical AROM. MedCalc Version 19.5.3 determined the "exact" Clopper-Pearson Interval (CPI). RESULTS: We found strong accuracy between palpation and MSUS videos on WMP when determining the direction of skin displacement during cervical flexion and extension (CPI= 78.56 to 96.89). There was moderate agreement between palpation and MSUS videos on WMP when determining the direction of the skin, superficial fascia, and deep fascia displacements during cervical lateral flexion and rotation (CPI= 42.25 to 64.13). CONCLUSION: Skin palpation during cervical flexion and extension may be useful in evaluating patients with myofascial pain syndrome (MPS). It is unclear what fascia system was evaluated when shoulders were palpated at the end of cervical lateral flexion and rotation. Palpation as diagnostic tool for MPS was not investigated.

Clinical effect of acupuncture along fascia, meridians, and nerves combined with ultrasound-guided paravertebral nerve block in the treatment of postherpetic neuralgia: a randomized parallel-controlled study.

OBJECTIVE: To observe the clinical efficacy of acupuncture along fascia, meridians, and nerves combined with ultrasound-guided nerve blockage in the treatment of postherpetic neuralgia. METHODS: A total of 61 outpatients with post-chest and back herpes zoster neuralgia were recruited in the Department of Pain at the Xiyuan Hospital, China Academy of Chinese Medical Sciences from May 2019 to June 2021. They were randomly divided into two groups. Thirty-one patients in the control group were treated with ultrasound-guided thoracic paravertebral nerve block (PVB) alone, one patient declined to continue during treatment ( 30), and thirty patients in the observation group received the acupuncture along the fascia, meridians, and nerves combined with ultrasound-guided PVB treatment ( 30). Both control and observation group received treatment weekly for 4 weeks. The medical history data such as age, sex, presence or absence of comorbidities and disease course were analyzed. The visual analog scale (VAS) score was used to assess the pain degree of two groups at T0 (before treatment), T1 (1-time treatment ended), T2 (2 times treatment ended), T3 (3 times treatment ended), and T4 (4 times treatment ended). The sleep state was examined by Pittsburgh Sleep Quality Index (PSQI) before and after the study. RESULTS: There was no significant difference in general conditions between the control group and the observation group (> 0.05). The VAS score in both control and observation group was decreased in a time-dependent manner after 1-4 weeks of treatment. There were no significant differences in VAS scores between the two groups after 1 or 2 weeks of treatment ( > 0.05). After 3 and 4 weeks of treatment, the VAS score was significantly decreased in the observation group compared with that in the control group ( < 0.001). In addition, the reduction in VAS score (after treatment-before treatment) between the two groups was statistically significant [D value: -1.53, 95% (-2.32, 0.74), < 0.001]. Furthermore, the sleep state of patients in both groups markedly improved and much obvious in the observation group than that in the control group ( < 0.05). CONCLUSION: These results suggest that a combination of acupuncture along fascia, meridians, and nerves with ultrasound-guided PVB treatment is more effective than ultrasound-guided PVB treatment alone.

Pro and Con: How Important Is the Exact Location of Adductor Canal and Femoral Triangle Blocks?

In this Pro-Con commentary article, we debate the importance of anterior thigh block locations for analgesia following total knee arthroplasty. The debate is based on the current literature, our understanding of the relevant anatomy, and a clinical perspective. We review the anatomy of the different fascial compartments, the course of different nerves with respect to the fascia, and the anatomy of the nerve supply to the knee joint. The Pro side of the debate supports the view that more distal block locations in the anterior thigh increase the risk of excluding the medial and intermediate cutaneous nerves of the thigh and the nerve to the vastus medialis, while increasing the risk of spread to the popliteal fossa, making distal femoral triangle block the preferred location. The Con side of the debate adopts the view that while the exact location of local anesthetic injection appears anatomically important, it has not been proven to be clinically relevant.

Acute Effects of Percussive Massage Therapy on Thoracolumbar Fascia Thickness and Ultrasound Echo Intensity in Healthy Male Individuals: A Randomized Controlled Trial.

Percussive massage therapy (PT) has been widely used by therapists and the fitness population to treat myofascial-related conditions. However, there is no evidence to confirm the effects of PT on the fascia. This study aimed to investigate the effects of PT on thoracolumbar fascia (TLF) morphology and other related outcomes. METHODS: Sixty-six healthy males participated and were randomly allocated into a percussive massage group (PT group) and a control group. The PT group received 15 min of back percussion massage, while the control group rested prone lying in the same environment for 15 min. Thoracolumbar fascia (TLF) thickness and echo intensity, perceived stiffness, lumbar flexibility, and skin temperature were measured in both groups before and immediately after the intervention. RESULT: TLF thickness and lumbar flexibility did not change when compared in the two groups. However, the echo intensity (left side, difference -3.36, 95% CI -5.1 to -1.6; right side, difference -4.39, 95% CI -6.1 to -2.7) and perceived stiffness (difference, -1.18, 95% CI -1.84 to -0.52) in the TLF region were significantly lower in the PT group than in the control group and were accompanied by increased skin temperature (difference 0.29, 95% CI 0.11 to 0.48). CONCLUSION: We suggest that a 15 min PT with 30 Hz on the back region could reduce TLF echo intensity and perceived stiffness and increase skin temperature in healthy men individual.

Effects of dry needling and stretching exercise versus stretching exercise only on pain intensity, function, and sonographic characteristics of plantar fascia in the subjects with plantar fasciitis: a parallel single-blinded randomized controlled trial.

OBJECTIVES: Plantar fasciitis is a common problem in the foot region which has negative considerable impact on foot function. METHODS: In this parallel blinded randomized controlled trial, a total of thirty-seven subjects with plantar fasciitis (forty feet) were enrolled randomly to either the control group (stretching exercise) or the experimental group (stretching exercise plus dry needling). All interventions lasted six weeks and both groups were followed for two weeks. Primary outcomes were first step pain, pain, and activity daily function subscales of the FAOS questionnaire and secondary outcomes were plantar fascia thickness, and echogenicity. RESULTS: The mixed model ANOVAs showed significant group × time interactions for all primary outcomes. In both groups, first step pain and both subscales of the FAOS questionnaire were improved compared to baseline measurements. There were considerable differences between the two groups and the experimental group experienced more improvements in primary outcomes compared to the control group. For secondary outcomes, plantar fascia thickness at insertion significantly decreased, and the echogenicity in the two regions significantly increased in the experimental group compared to the control group. CONCLUSION: These results suggest that the combination of dry needling and stretching exercises can be an effective conservative treatment for plantar fasciitis subjects.

Thoracolumbar fascia mobility and chronic low back pain: Phase 2 of a pilot and feasibility study including multimodal chiropractic care.

BACKGROUND: Thoracolumbar fascia mobility observed with ultrasound imaging and calculated as shear strain is lower in persons with chronic low back pain. This pilot and feasibility trial assessed thoracolumbar shear strain in persons with chronic low back pain following spinal manipulation and over an 8-week course of multimodal chiropractic care. METHODS: Adults self-reporting chronic low back pain ≥ 1 year participated between September 2019 and April 2021 in a trial using ultrasound imaging to measure thoracolumbar shear strain. Ultrasound imaging occurred 2-3 cm lateral to L2-3 while participants relaxed prone on an automated table moving the lower extremities downward 15 degrees, for 5 cycles at 0.5 Hz. Pain intensity on an 11-point numerical rating scale, disability, pain interference, and global improvement were also collected. Participants received 8-weeks of twice-weekly chiropractic care including spinal manipulation, education, exercise, self-management advice and myofascial therapies. Shear strain was computed using 2 methods. The highest shear strain from movement cycles 2, 3, or 4 was averaged over right and left sides for each participant. Alternately, the highest shear strain from movement cycle 3 was used. All data were analyzed over time using mixed-effects models. Estimated mean changes are reported. RESULTS: Of 20 participants completing 8-weeks of chiropractic care (female n = 11), mean (SD) age was 41 years (12.6); mean BMI was 28.5 (6.2). All clinical outcomes improved at 8-weeks. Mean (95% confidence interval) pain intensity decreased 2.7 points (- 4.1 to - 1.4) for females and 2.1 points (- 3.7 to 0.4) for males. Mean Roland-Morris disability score decreased by 5 points (- 7.2 to - 2.8) for females, 2.3 points (- 4.9 to 0.2) for males. Mean PROMIS pain interference T-score decreased by 8.7 points (- 11.8 to - 5.5) for females, 5.6 points (- 9.5 to - 1.6) for males. Mean shear strain at 8-weeks increased in females 5.4% (- 9.9 to 20.8) or 15% (- 0.5 to 30.6), decreasing in males 6.0% (- 24.2 to 12.2) or 2% (- 21.0 to 16.8) depending on computational method. CONCLUSION: Spinal manipulation does not likely disrupt adhesions or relax paraspinal muscles enough to immediately affect shear strain. Clinical outcomes improved in both groups, however, shear strain only increased in females following 8-weeks of multimodal chiropractic care. Trial registration ClinicalTrials.gov registration is NCT03916705.

Evidence of in-vivo myofascial force transfer in humans- a systematic scoping review.

BACKGROUND: The fascial system not only enables the body to operate in an integrated manner but modifies its tension in response to the stress on it. Recent animal, cadaveric and in-vitro trials have shown that "myofascial force transmission" (MFT) can play a major role in homeostasis, musculoskeletal function and pain. Human evidence for the in-vivo existence of MFT is scarce. OBJECTIVE: This scoping review attempts to gather and interpret the available evidence of the in-vivo existence of MFT in humans, its role in homeostasis, and musculoskeletal function. METHOD: A search of major databases using the keywords 'myofascial force transmission' and 'epimuscular force transmission' yielded 247 articles as of November 2021. For the final analysis, only original in-vivo human studies were considered. In-vitro human studies, cadaveric or animal studies, reviews, and similar studies were excluded. A qualitative analysis of the studies was conducted after rating it with the Oxford's Center for Evidence -based Medicine (CEBM) scale. RESULT: Twenty studies ranging from randomized controlled trials (RCTs) to case studies covering 405 patients have been included in this review. The analysed trials were highly heterogeneous and of lower methodological quality meddling with the quantitative analysis. The majority of the appraised studies demonstrated a higher probability of MFT existence, while two studies revealed a lower probability. CONCLUSION: Our search for proof of the in vivo existence of MFT in humans has led us to support such an existence, albeit prudently. Previous research on animals and human cadavers reinforces our finding. We are optimistic that the forthcoming studies on the topic will pave the way for the unraveling of several musculoskeletal riddles that are currently unknown or less well-known.

Fascial manipulation as an adjunct to physiotherapy management in obstetric brachial plexus palsy: A case report.

The integrity of connective tissue sheaths surrounding the nerves influences both the severity and the potential for recovery of brachial plexus lesions. This study presents an innovative, early onset, multidisciplinary approach to obstetric brachial plexus palsy. This approach is aimed at functional recovery of the nerve lesion and includes mobilization of the fascia using the Fascial Manipulation® method. This case study discusses how, in addition to conventional treatment, interventions aimed at the fascial system can potentially affect tension around the neural sheaths, enhance proprioceptive input and facilitate movement to influence obstetric brachial plexus palsy outcomes.

Hip abduction machine is better than free weights to target the gluteus medius while minimizing tensor fascia latae activation.

INTRODUCTION: Changes in the lower extremities' biomechanics are associated with gluteus medius (GMed) weakness and increased tensor fascia latae (TFL) activation. OBJECTIVE: To determine which exercises produce greater GMed activity while minimizing TFL activation during the concentric and eccentric phases of three single-joint strengthening exercises. DESIGN: Controlled laboratory study. SETTING: Laboratory. PARTICIPANTS: Eleven males (age: 29.18 ± 4.51 years; body mass: 84.01 ± 14.48 kg; height: 1.74 ± 0.07 m; body fat: 16.34 ± 3.33%). MAIN OUTCOME MEASURES: GMed and TFL activation and activation ratio while performing ten maximal repetitions of three exercises: side-lying hip abduction (SLHA); clamshell (CLAM) and hip abductor machine (HAM). RESULTS: GMed activation was greater than TFL in all exercises in both concentric and eccentric phases. There were no differences in GMed activation between the three exercises in both phases. TFL activation was greater in SLHA compared to HAM and CLAM during both phases. In both concentric and eccentric phases, GMed:TFL ratio was greater in HAM compared to CLAM and SLHA. CONCLUSIONS: GMed had increased activation compared to TFL in all analyzed exercises. Considering GMed:TFL ratio, if the goal is to preferentially activate GMed while minimizing TFL activation, the hip abductor machine seems to be the best exercise.

Intra- and inter-observer concordance of a fascial standing flexion test in children.

INTRODUCTION: Manual clinical tests must be highly reliable and valid to help in diagnosing, monitoring, and treating patients. Recent research highlighted the role of the fascia; thus, it is important to develop inexpensive, easy-to-use, and clinically valid procedures to assess this tissue in the field of manual therapy. The purpose of this study was to determine the level of inter- and intra-examiner concordance when performing a fascial standing flexion test in children. DESIGN: The present study is a descriptive observational study. METHODS: Two examiners tested 24 healthy children between 11 and 12 years of age performing two trials with the proposed fascial test. Inter- and intra-examiner data were analyzed using unweighted kappa coefficients and percentage agreement. RESULTS: We observed zero inter-examiner reliability in the fascial standing flexion test (mean κ = -0.071, mean percentage agreement of 43.7%), and moderate intra-examiner reliability (mean κ = 0.693, mean percentage agreement of 85.4%). CONCLUSION: The reliability and validity of the fascial standing flexion test must be improved before it can be recommended for use in a clinical setting.
