- Pelvic floor myofascial pain severity and pelvic floor disorder symptom bother: Is there a correlation? [Journal Article]
- AJAm J Obstet Gynecol 2019 Jul 15
- CONCLUSIONS: Pelvic floor myofascial pain was common in patients seeking evaluation for pelvic floor disorder symptoms. Location and severity of pelvic floor myofascial pain was significantly correlated with degree of symptom bother, even after controlling for postmenopausal status. Given the high prevalence of pelvic floor myofascial pain in these patients and correlation between pain severity and degree of symptom bother, a routine assessment for pelvic floor myofascial pain should be considered for all patients presenting for evaluation of pelvic floor symptoms.
- Vaginal Diazepam for Nonrelaxing Pelvic Floor Dysfunction: The Pharmacokinetic Profile. [Journal Article]
- JSJ Sex Med 2019; 16(6):763-766
- CONCLUSIONS: Serum plasma concentrations of vaginally administered diazepam are low; however the half-life is prolonged.Vaginal administration of diazepam results in lower peak serum plasma concentration, longer time to peak concentration, and lower bioavailability than standard oral use. Providers should be aware that with diazepam's long half-life, accumulating levels would occur with chronic daily doses, and steady-state levels would not be reached for up to 1 week. This profile would favor intermittent use to allow participation in physical therapy and intimacy. Larish AM, Dickson RR, Kudgus RA, et al.

Twenty-four basic and clinical studies and case reports are included in this quarterly review of the myofascial pain literature. The majority of publications focus on invasive techniques, especially dry needling. We hope, that this not suggest that clinicians and researchers are slowly moving away from manual trigger point (TrP) approaches. While some physiotherapists have bought into the notion that hands-on approaches are a thing of the past, since "pain is in the brain" and "the issues are not in the tissues," there is also a body of research that aims to combine so-called top-down and bottom-up therapies. Combining manual therapy and dry needling with pain neuroscience education is likely the preferred method using a multimodal approach (Puentedura and Flynn, 2016; Lluch Girbes et al., 2015).
- The repeated bout effect can occur without mechanical and neuromuscular changes after a bout of eccentric exercise. [Journal Article]

Changes in muscle fascicle mechanics have been postulated to underpin the repeated bout effect (RBE) observed following exercise-induced muscle damage (EIMD). However, in the medial gastrocnemius (MG), mixed evidence exists on whether fascicle stretch amplitude influences the level of EIMD, thus questioning whether changes in fascicle mechanics underpin the RBE. An alternative hypothesis is that neural adaptations contribute to the RBE in this muscle. The aim of this study was to investigate the neuromechanical adaptations during and after repeated bouts of a highly controlled muscle lengthening exercise that aimed to maximize EIMD in MG. In all, 20 subjects performed two bouts of 500 active lengthening contractions (70% of maximal activation) of the triceps surae, separated by 7 days. Ultrasound constructed fascicle length-torque (L-T) curves of MG, surface electromyography (EMG), maximum torque production, and muscle soreness were assessed before, 2 hours and 2 days after each exercise bout. The drop in maximum torque (4%) and the increase in muscle soreness (24%) following the repeated bout were significantly less than following the initial bout (8% and 59%, respectively), indicating a RBE. However, neither shift in the L-T curve nor changes in EMG parameters were present. Furthermore, muscle properties during the exercise were not related to the EIMD or RBE. Our results show that there are no global changes in gastrocnemius mechanical behavior or neural activation that could explain the observed RBE in this muscle. We suggest that adaptations in the non-contractile elements of the muscle are likely to explain the RBE in the triceps surae.

Neck and shoulder stiffness is a typical subjective symptom in developed countries. This stiffness is caused by factors such as muscle tension and poor blood flow, leading to reduce work efficiency and diminish QOL. NKCP®, a natto-derived dietary food supplement whose main component is bacillopeptidase F, has antithrombotic, fibrinolytic, and blood viscosity-lowering effects. Here, we investigated the effect of NKCP® on neck and shoulder stiffness in a double-blind placebo-controlled randomized crossover study. Thirty subjects with neck and shoulder stiffness were randomly divided into 2 groups and ingested 250 mg of NKCP® or placebo daily for 4 weeks. Headache score significantly improved in the NKCP® group compared to the placebo group. Moreover, NKCP® significantly improved the score of visual analogue scale for neck and shoulder stiffness and pain, reduced muscle stiffness of the neck, and increased the skin surface temperature of neck and shoulders, compared to before ingestion. No adverse effects were observed during this study. These results suggest that NKCP® may alleviate headaches and chronic neck and shoulder stiffness and pain.
- Antioxidants for preventing and reducing muscle soreness after exercise. [Review]
- CDCochrane Database Syst Rev 2017 12 14; 12:CD009789
- CONCLUSIONS: There is moderate to low-quality evidence that high dose antioxidant supplementation does not result in a clinically relevant reduction of muscle soreness after exercise at up to 6 hours or at 24, 48, 72 and 96 hours after exercise. There is no evidence available on subjective recovery and only limited evidence on the adverse effects of taking antioxidant supplements. The findings of, and messages from, this review provide an opportunity for researchers and other stakeholders to come together and consider what are the priorities, and underlying justifications, for future research in this area.
- Effect of Physical Methods of Lymphatic Drainage on Postexercise Recovery of Mixed Martial Arts Athletes. [Randomized Controlled Trial]
- CJClin J Sport Med 2019; 29(1):49-56
- CONCLUSIONS: The lymphatic drainage methods, whether manual or using electro-stimulation and DO, improve postexercise regeneration of the forearm muscles of MMA athletes. The methods can be an important element of therapeutic management focused on optimizing training effects and reducing the risk of injuries of the combat sports athletes.

People working at computers often suffer from overload-related muscle pain, and physical and mental discomfort. The aim of the study was to evaluate the effectiveness of chair massage, conducted in the workplace among white-collar workers, in relieving symptoms of musculoskeletal strain related to prolonged sitting posture. The study was conducted in 124 white-collar workers, 55 women and 69 men, aged 33.7 ± 7.6 years. Subjects were randomly assigned to three groups: chair massage program, relaxing music sessions, and a control group, each of four-week duration. Each group was evaluated before and after the program completion. Pain perception was assessed algometrically as a threshold for compression pain of neck muscles, measured in kg/cm2. The relaxation level was assessed from the heart rate variability. We found that the chair massage increased both the pain threshold in all tested muscles (p < 0.001) and the relaxation level from 31.9% to 41.6% (p < 0.05). In the group with music sessions, muscle pain threshold remained unchanged, except for the trapezoid muscle where it decreased (p < 0.05), while the relaxation level increased from 26.0% to 33.3% (p < 0.05). In both massage and relaxing music groups, there was a significant decrease in muscle tension (p < 0.01). Changes in the control group were inappreciable. We conclude that the chair massage performed in the workplace is an effective method for prevention of musculoskeletal overstrain related to prolonged sitting posture. The program seems worth implementing in various occupational environments.

- Relations between the results of complex clinical and neurophysiological examinations in patients with temporomandibular disorders symptoms. [Journal Article]
- CCranio 2018; 36(1):44-52
- CONCLUSIONS: sEMG is a suitable tool for prosthodontists because it provides objective results on the stomatognathic system muscles function. Pain and other temporomandibular symptoms detected mostly unilaterally significantly increase muscle tension of the masticatory muscles and diminish muscle motor units recruitment during maximal contraction. Effects may spread to the neck and shoulder girdle muscles.
