Effects of percutaneous neuromodulation on the mechanical characteristics of the rectus femoris and the vastus lateralis in football players: a pilot study

Abstract Background and Aims Percutaneous neuromodulation is an ultrasound-guided technique aimed at the peripheral nerve, using an acupuncture needle as an electrode for a TENS type current which has demonstrated to have positive effects for pain but not for muscle activity. Tensiomyography (TMG) is a non-invasive assessment technique, which is reliable and provides instant information on the mechanical characteristics of superficial muscles. The aim of this study is to evaluate whether percutaneous neuromodulation produces effects on muscle contraction parameters. Material and Methods A longitudinal, analytic and experimental study with a control group, comprising a sample of 11 football players in the 3rd Division, randomly assigned to an intervention group (IG = 5) and a control group (CG = 6). Athletes were assessed using tensiomyography (TMG-S2, EMF-FURLAN & Co.) parameters: maximum deformation (Dm), response time (Td), contraction time (Tc), relaxation time (Tr) and time of contraction maintenance (Ts) of the rectus femoris (RF) and vastus lateralis (VL). Both legs were assessed immediately after the training session (Pre), after 10' rest period post intervention (Post1) and after 12 hours of rest on the following day (Post2). Both femoral nerves were intervened with a needle on the long axis and in a transverse section just below the same. An Electrostimulator (ITO, model ES- 160), was applied to the IG during 5' using a TENS current of 200µs, 1 Hz and with sufficient intensity to achieve a visible contraction of the quadriceps without discomfort. The channel was closed with adhesive electrodes placed medial to the ASIS. The CG received a placebo treatment with needles and electrodes placed on the same anatomical points and connected to an electrostimulator without current during 5' (Physio Invasiva device). Results On the right RF the Td decreased in the IG (pre/post2: P = 0.005) and between groups (post1: P = 0.017 and post2: P = 0.014). For Tc we found differences between the IG (pre/post2: P= 0.008) and the CG (post1/post2: P = 0.019). The left RF increased Tc in the CG (P = 0.036) and pre/post2 and Ts in the CG compared to the IG (post2: P = 0.0480.048). In the left VL Dm increased (pre/post2: P = 0.046 and post1/post2: P = 0.018), Td (pre/post2: P = 0.010) and Tc (pre/post2: P = 0.051 and post1/post2: P = 0.003) for the CG. In the IG, the right VL, both Td (P = 0.024) and Tc (P = 0.021) decreased between post1/post2. For the intragroup analysis (pre, post1 and post2) the Student's t-test was used, whereas for the intragroup analysis, the ANOVA was used (significance > P 0.05). Conclusions Considering the characteristics of the sample and understanding that the decrease of TMG parameters represents an improvement in the mechanical characteristics of the muscle, the findings of this pilot study suggest that the intervention with percutaneous neuromodulation in the IG produces greater recovery and improved activation after 12 hours on the RF and VL. However, the increase of these parameters in the CG results in greater fatigue.

Aim: The research was conducted as a randomized controlled pilot study to evaluate the effects of reflexology on lactation in mothers who delivered by cesarean section (CS). Methods: A single-blind randomized controlled experimental study was conducted with a total of 60 postpartum women in the reflexology application (n = 30) and control groups (n = 30). After the CS, the mothers in the control group were given approximately 3-h routine nursing care after recovering from the effects of anesthesia; the introductory information form was applied, and the Breastfeeding Charting System and Documentation Tool (LATCH) and visual analog scale (VAS) for the signs of the onset of lactation were implemented on the first and second days. Reflexology was applied to the women in the intervention group after an average of 3 h following the mother’s condition had become stable and she had recovered from the effects of anesthesia. Reflexology was applied a total of 20 min – 10 min for the right foot, 10 min for the left foot – twice a day with 8-h intervals on the first and second days after CS. After the last reflexology application, the LATCH and VAS for the signs of the onset of lactation were applied. Results: Of the women, 70% breastfed their babies within 60 min after delivery; 46.7% of the mothers received breastfeeding training and 81.7% needed support for breastfeeding after the CS. The LATCH breastfeeding scores of the women in the intervention group on both days were significantly higher compared to those of the women in the control group (p < 0.001). On the first day after the CS, apart from breast pain, there was no significant difference between the two groups in terms of breast heat and breast tension (p > 0.05). On the second day after the CS, apart from breast tension, there was no significant difference between the groups in terms of breast heat and breast pain (p < 0.05). In the study, women in the intervention group were found to have higher scores in terms of all three symptoms compared to the control group (p < 0.05). Conclusions: In the study, it was determined that LATCH scores and signs of the onset of breastfeeding increased in the mothers who received reflexology after CS.

Background/Aims Treating pelvic fractures non-operatively is possible. The immobilisation stage of recovery requires different adjustment processes compared to those used in operative treatment. The aim of the present study was to prove the additional benefit an antigravity treadmill can have on patients with non-operatively treated pelvic fractures. Methods A prospective pilot study, including patients with non-operatively treated pelvic fractures as the intervention group and healthy volunteers as a control group, was undertaken. Patients of the intervention group participated in a training session with an antigravity treadmill every 3 days for a total of 40 days, in addition to physiotherapy, lymph drainage massage and manual therapy. Patients were evaluated using a dynamic gait index, and a numeric rating scale on three successive dates, to assess their pain. A standardised gait analysis was also carried out. Results The intervention group comprised 9 patients, while 33 patients made up the control group. All patients completed the protocols and experienced a significant decrease in pain and increase of mobility. Gait analysis showed that by the 40-day follow-up, patients in the intervention group had regained almost normal gait patterns when compared to the control group. At each time point, a significant improvement in patients' gait patterns could be seen. Conclusions The results concurred with previous studies, suggesting that the antigravity treadmill is safe and that recovery to almost normal gait patterns is possible, while the comparison to a healthy group strengthened the data. The present prospective study thus showed promising results regarding the efficacy of the antigravity treadmill, despite study limitations.

Symptom Scores

Gastroesophageal reflux disease (GERD) affects approximately 20% of Australians. Patients suffer a burning sensation known as heartburn due to the movement of acidic stomach content into the esophagus. There is anecdotal evidence of the effectiveness of prebiotic sugarcane flour in controlling symptoms of GERD. This pilot study aimed to investigate the effectiveness of a prebiotic sugarcane flour in alleviating symptoms in medically-diagnosed GERD patients. This pilot study was a single center, double-blinded, placebo-controlled randomized trial conducted on 43 eligible participants. The intervention group (n = 22) were randomized to receive 3 g of sugarcane flour per day, and the control group (n = 21) received 3 g of cellulose placebo per day. Symptoms of gastroesophageal reflux disease were assessed before and after three weeks treatment using the validated Gastroesophageal Reflux Disease-Health Related Quality of Life questionnaire (GERD-HRQL). After three weeks there were significant differences in symptoms for heartburn, regurgitation, and total symptoms scores (p < 0.05) between the sugarcane flour and placebo. Mean GERD-HRQL scores increased in the placebo group for regurgitation (mean increase 1.7; 95% CI 0.23 to 3.2; p = 0.015) and total symptom scores (2.9; 95% CI 0.26 to 5.7; p = 0.033). In contrast, there were significant reductions in heartburn (mean decrease −2.2; 95% CI −4.2 to −0.14; p = 0.037) and total symptom scores (−3.7; 95% CI −7.2 to −0.11; p = 0.044) in the intervention group. This pilot study has shown significant positive effects of sugarcane flour in the reduction of GERD symptoms, and a larger randomized controlled trial is warranted.

Purpose: The “11+ Kids” injury-prevention program has been shown to reduce injuries and related costs in youth football players less than 14 y of age. A major argument to convince coaches to use this exercise-based injury-prevention program is a potential performance enhancement of the players. Therefore, this study investigated the effects of the “11+ Kids” program on isokinetic strength. Methods: Two teams were randomly assigned to the intervention and control groups. The intervention group replaced their warm-up by the “11+ Kids” and the control group warmed up as usual. Two days before and after the 10-wk intervention, isokinetic strength of the hip adductors and abductors, knee flexors and extensors, and ankle invertors and evertors was tested. Results: Thirty-one players (mean age 11.5 [0.8] y) completed the study. The intervention group showed large improvements in all isokinetic strength measures (P < .001 for all measures; Cohen d = 0.8–1.4), whereas the control group only showed negligible to medium positive effects (P values ranging from .006 to .718; Cohen d = −0.1 to 0.7). The intervention was beneficial compared with the control group regarding isokinetic strength of the hip adductors (P < .001), knee flexors (P = .002), and ankle evertors (P < .001) and invertors (P = .005). Conclusions: Given the relatively short intervention period of 10 wk, the observed improvements relate to a practically meaningful effect of the intervention. The gain in strength may improve players’ performance and may contribute to a reduction of injury risk in the long-term application.

Abstract Background Hospital stays and medical interventions are accompanied by worries and anxiety in children and parents. Recent studies show that hospital clowns may reduce anxiety and enhance well-being. However, so far studies are based solely on subjective measures and clowns are usually not integrated in medical routine. With this pilot study, we aim to provide both psychological and physiological evidence of positive effects of clowns’ interventions in hospitalized children. Patients/Method In a consecutive randomized intervention-control group design with 31 children aged 4 to 13 years, 17 patients were accompanied by a clown prior to surgery or during ward round (intervention group) and 14 were not (control group). Saliva samples for oxytocin measurement were taken from all patients before hospitalization (T1) and prior to surgery or after ward round (T2). Self- and parents-reports were obtained at T1, T2 as well as at time of discharge from hospital (T3) regarding children’s anxiety (STAI), worries and well-being. Clowns evaluated their success in cheering up the child. Health professionals were asked for their acceptance of clowns in hospitals. Results Children in the intervention group had lower anxiety ratings and a higher oxytocin concentration at T2 as compared with T1; the control group showed no changes. Parents rated the well-being of their children higher if their child had clown’s contact and were more willing to recommend the hospital. The staff judged the clowns as helpful for patients. Discussion Consistent psychological and physiological results suggest the positive impact of a clown’s intervention in hospitalized children.

Positive parenting programs are a key strategy to promote the development of parental competence. We designed a pilot study based on parental self-efficacy to promote healthy lifestyles in their children aged between 2 to 5 years old. In this pilot study, we aimed to assess the effects of a parenting program on parental self-efficacy and parenting styles. Twenty-five parents were allocated into intervention (N = 15) and control group (N = 10). Parents from the intervention group received four group sessions (120 mi per session) to develop a positive parenting, parenting styles and parenting skills regarding to children’s diet, exercise, and screen time, and two additional sessions about child development and family games. Parents from the control group received these two latter sessions. Parental self-efficacy, parenting styles, and meal-related parenting practices were measured before and after the intervention and at 3-month follow-up. Acceptability and feasibility of the program was also measured. Quantitative data were analyzed using the repeat measures ANOVA and ANCOVA tests and the effect size calculation. Content analysis was used to analyse open questions. Positive trends were found regarding parental self-efficacy and the use of authoritative parenting style. Parents also reported a great acceptability of the program getting high satisfaction. According to the feasibility barriers and facilitators aspects were identified. The positive trends founded in this study support the development of parenting programs to promote healthy lifestyle in children.

Abstract Background We aimed to determine the effectiveness of 4 weeks of balance exercise compared with no intervention on objectively measured postural sway. Methods This was a single-center parallel randomized controlled, open label, trial. A six-sided dice was used for allocation at a 1:1-ratio between exercise and control. The trial was performed at a university hospital clinic in Sweden and recruited community-dwelling older adults with documented postural instability. The intervention consisted of progressively challenging balance exercise three times per week, during 4 weeks, with follow-up at week five. Main outcome measures were objective postural sway length during eyes open and eyes closed conditions. Results Sixty-five participants aged 70 years (balance exercise n = 32; no intervention n = 33) were randomized. 14 participants were excluded from analysis because of early dropout before follow-up at week five, leaving 51 (n = 22; n = 29) participants for analysis. No significant differences were detected between the groups in any of the postural sway outcomes. Within-group analyses showed significant improvements in hand grip strength for the intervention group, while Timed Up & Go improvements were comparable between groups but only statistically significant in the control group. Conclusions Performing balance exercise over a four-week intervention period did not acutely improve postural sway in balance-deficient older adults. The lower limit in duration and frequency to achieve positive effects remains unclear. Trial registration Clinical trials NCT03227666, July 24, 2017, retrospectively registered.

Long Term Retention

Abstract Context Some medical schools integrate STOP THE BLEED® training into their curricula to teach students how to identify and stop life threatening bleeds; these classes that are taught as single day didactic and hands-on training sessions without posttraining reviews. To improve retention and confidence in hemorrhage control, additional review opportunities are necessary. Objectives To investigate whether intermittent STOP THE BLEED® reviews were effective for long term retention of hemorrhage control skills and improving perceived confidence. Methods First year osteopathic medical students were asked to complete an eight item survey (five Likert scale and three quiz format questions) before (pretraining) and after (posttraining) completing a STOP THE BLEED® training session. After the surveys were collected, students were randomly assigned to one of two study groups. Over a 12 week intervention period, each group watched a 4 min STOP THE BLEED® review video (intervention group) or a “distractor” video (control group) at 4 week intervals. After the 12 weeks, the students were asked to complete an 11 item survey. Results Scores on the posttraining survey were higher than the pretraining survey. The median score on the five Likert scale items was 23 points for the posttraining survey and 14 points for the pretraining survey. Two of the three knowledge based quiz format questions significantly improved from pretraining to posttraining (both p<0.001). On the 11 item postintervention survey, both groups performed similarly on the three quiz questions (all p>0.18), but the intervention group had much higher scores on the Likert scale items than the control group regarding their confidence in their ability to identify and control bleeding (intervention group median = 21.4 points vs. control group median = 16.8 points). Conclusions Intermittent review videos for STOP THE BLEED® training improved medical students’ confidence in their hemorrhage control skills, but the videos did not improve their ability to correctly answer quiz-format questions compared with the control group.

Abstract Introduction Medication self-management support has been recognised as an essential element in primary health care to promote medication adherence and health outcomes for older people with chronic conditions. A patient-centred intervention empowering patients and supporting medication self-management activities could benefit older people. This pilot study tested a newly developed medication self-management intervention for improving medication adherence among older people with multimorbidity. Method This was a two-arm randomised controlled trial. Older people with multimorbidity were recruited from a community healthcare centre in Changsha, China. Participants were randomly allocated to either a control group receiving usual care (n = 14), or to an intervention group receiving three face-to-face medication self-management sessions and two follow-up phone calls over six weeks, targeting behavioural determinants of adherence from the Information-Motivation-Behavioural skills model (n = 14). Feasibility was assessed through recruitment and retention rates, outcome measures collection, and intervention implementation. Follow-up data were measured at six weeks after baseline using patient-reported outcomes including medication adherence, medication self-management capabilities, treatment experiences, and quality of life. Preliminary effectiveness of the intervention was explored using generalised estimating equations. Results Of the 72 approached participants, 28 (38.89%) were eligible for study participation. In the intervention group, 13 participants (92.86%) completed follow-up and 10 (71.42%) completed all intervention sessions. Ten participants (71.42%) in the control group completed follow-up. The intervention was found to be acceptable by participants and the intervention nurse. Comparing with the control group, participants in the intervention group showed significant improvements in medication adherence (β = 0.26, 95%CI 0.12, 0.40, P < 0.001), medication knowledge (β = 4.43, 95%CI 1.11, 7.75, P = 0.009), and perceived necessity of medications (β = −2.84, 95%CI -5.67, −0.01, P = 0.049) at follow-up. Conclusions The nurse-led medication self-management intervention is feasible and acceptable among older people with multimorbidity. Preliminary results showed that the intervention may improve patients’ medication knowledge and beliefs and thus lead to improved adherence.

Medication deprescribing is essential to prevent inappropriate medication use in multimorbid patients. However, experience of deprescribing in Danish Subacute Medical Outpatient Clinics (SMOCs) is limited. The objective of our pilot study was to evaluate the feasibility and sustainability of a collaborative deprescribing intervention by a pharmacist and a physician to multimorbid patients in a SMOC. A randomized controlled pilot study was conducted, with phone follow-up at 30 and 365+ days. A senior pharmacist performed a systematic deprescribing intervention using the Screening Tool of Older Persons’ potentially inappropriate Prescriptions (STOPP) criteria, the Danish deprescribing list, and patient interviews. A senior physician received the proposed recommendations and decided which should be implemented. The main outcome was the number of patients having ≥1 medication where deprescribing status was sustained 30 days after inclusion. Out of 76 eligible patients, 72 (95%) were included and 67 (93%) completed the study (57% male; mean age 73 years; mean number of 10 prescribed medications). Nineteen patients (56%) in the intervention group and four (12%) in the control group had ≥1 medication where deprescribing status was sustained 30 days after inclusion (p = 0.015). In total, 37 medications were deprescribed in the intervention group and five in the control group. At 365+ days after inclusion, 97% and 100% of the deprescribed medications were sustained in the intervention and control groups, respectively. The three most frequently deprescribed medication groups were analgesics, cardiovascular, and gastrointestinal medications. In conclusion, a collaborative deprescribing intervention for multimorbid patients was feasible and resulted in sustainable deprescribing of medication in a SMOC.
