Effects of different treatments on pain, functional disability, position sense and range of motion in elite bodybuilders with chronic low back pain.

Back pain is one of the major global challenges and is one of the most prevalent musculoskeletal disorders occurring in 80% of people at least once in their lifetime. Therefore, the need to find appropriate treatment methods for this issue is very important. The objective is to examine the short-term and acute effects of a treatment session with dry needling, massage therapy, stretching exercises and Kinesio tape on pain, functional disability, position sense and range of motion in elite bodybuilders with non-specific chronic low back pain. The sample of this quasi-experimental study consisted of 48 bodybuilders with non-specific chronic low back pain (all male, mean age = 25.96 ± 2.18 years; mean weight = 74.45 ± 4.51 kg; mean height = 173.88 ± 3.74 cm; mean BMI = 24.60 ± 0.74 kg/m2) who randomly were placed in 4 dry needling, massage therapy, stretching exercises and Kinesio tape groups. The duration of each intervention was 30 min. The dependent variables in this study included the massage range of motion, position sense tests and visual pain scale that were taken separately from each subject in pretest, posttest (acute effect) and follow-up test (72 h after posttest; short-term effect). The results of a 4 (groups) × 3 (time) the mixed ANOVAs showed that pain in the short-term phase was significantly lower in the dry needling group than in the stretching and massage groups (P < 0.05). Also in the acute effect phase, the flexion range of motion was significantly lower in the dry needling group than in the massage group (P < 0.05). Furthermore, the two groups of stretching and massage exercises showed significantly greater range of motion (P < 0.05). Other comparisons were not significant (P > 0.05). The findings of the study showed that both massage and stretching treatment have higher acute effects, while dry needling treatment was more effective in follow up. On the other hand, these findings show that these treatment methods can have immediate and lasting positive effects in improving the performance in elite bodybuilders with non-specific chronic low back pain.

Combined effect of myofascial release and passive stretching on plantar pressure in individual with hamstring tightness- an experimental study.

INTRODUCTION: The lower kinetic chain is known to be affected by hamstring tightness which causes biomechanical alterations. As per the literature, short hamstring might cause prolonged forefoot loading, which can cause higher repeated stress on the plantar fascia. There is evidence supporting the use of various stretching and myofascial release techniques for hamstring tightness, further research is needed to investigate their impact on plantar pressure. Hence the study aims to determine combined effect of myofascial release and passive stretching on plantar pressure in individual with hamstring tightness. METHODS: This was an experimental pre-post study design with 67 randomised screenings from asymptomatic health care science students aged 18 to 25. From this scientific survey, a sample size of 47 students having HMS tightness based on the popliteal angle were recruited using a universal goniometer. An intervention was proposed that included MFR and passive stretching in 3 sessions on alternate days. Plantar pressure of these individuals was noted by using the "Harris and Beath foot printing mat" before and after the intervention. RESULT: Significant pressure changes were observed after intervention: great toe of right side (p = 0.001), toes 2 to 5 of right side (p = 0.010) and left side (p = 0.008), first metatarsal of left side (p = 0.010), lateral forefoot of right side (p = 0.019) and left (p = 0.018), medial heel (p = 0.044), and lateral heel of right side (p = 0.025). These values substantiate the enhancement in plantar pressure. CONCLUSION: The combined effect of Myofascial release and passive stretching in an individual with hamstring tightness resulted in a significant increase in popliteal angle and plantar pressure.

Synergistic difference in the effect of stretching on electromechanical delay components.

This study investigated the synergistic difference in the effect of stretching on electromechanical delay (EMD) and its components, using a simultaneous recording of electromyographic, mechanomyographic, and force signals. Twenty-six healthy men underwent plantar flexors passive stretching. Before and after stretching, the electrochemical and mechanical components of the EMD and the relaxation EMD (R-EMD) were calculated in gastrocnemius medialis (GM), lateralis (GL) and soleus (SOL) during a supramaximal motor point stimulation. Additionally, joint passive stiffness was assessed. At baseline, the mechanical components of EMD and R-EMD were longer in GM and GL than SOL (Cohen's d from 1.78 to 3.67). Stretching decreased joint passive stiffness [-22(8)%, d = -1.96] while overall lengthened the electrochemical and mechanical EMD. The mechanical R-EMD components were affected more in GM [21(2)%] and GL [22(2)%] than SOL [12(1)%], with d ranging from 0.63 to 1.81. Negative correlations between joint passive stiffness with EMD and R-EMD mechanical components were found before and after stretching in all muscles (r from -0.477 to -0.926; P from 0.007 to <0.001). These results suggest that stretching plantar flexors affected GM and GL more than SOL. Future research should calculate EMD and R-EMD to further investigate the mechanical adaptations induced by passive stretching in synergistic muscles.

The Training and Tapering Practices of Highland Games Heavy Event Athletes.

ABSTRACT: Winwood, PW, Keogh, JW, Travis, SK, Grieve, I, and Pritchard, HJ. The training and tapering practices of Highland Games heavy event athletes. J Strength Cond Res 38(3): e116-e124, 2024-This study provides the first empirical evidence of how Highland Games heavy event athletes train and taper for Highland Games competitions. Athletes (n = 169) (mean ± SD: age 40.8 ± 10.7 years, height 181.2 ± 9.5 cm, weight 107.2 ± 23.0 kg, 18.8 ± 10.3 years of general resistance training, and 8.1 ± 6.9 years of competitive Highland Games experience) completed a self-reported 4-page online survey on training and tapering practices. Analysis by sex (male and female) and competitive standard (local or regional, national, and international) was conducted. Seventy-eight percent (n = 132) of athletes reported that they used a taper. Athletes stated that their taper length was 5.2 ± 3.5 days, with the step (36%) and linear tapers (33%) being the most performed. Athletes reported that their highest training volume and intensity were 5.5 and 3.8 weeks out (respectively) from competition, and all training ceased 2.4 ± 1.4 days before competition. Training volume decreased during the taper by 34%. Athletes typically stated that, tapering was performed to achieve recovery, peak performance, and injury prevention; training intensity, frequency, and duration stayed the same or decreased; game-specific training increased with reductions in traditional exercises; the caber toss, weight for height, and heavy weight throw were performed further out from competition than other events; muscular power and strength were the most common types of training performed; static stretching, foam rolling, and massage were strategies used in the taper; and poor tapering occurred because of life/work circumstances, lack of sleep/rest, or training too heavy/hard. These results may aid Highland Games athletes to optimize training and tapering variables leading to improved performances.

Effects of percussion massage therapy, dynamic stretching, and static stretching on physical performance and balance.

BACKGROUND: Percussion massage therapy is a popular approach in sport medicine for physical therapists, but few researchers have investigated the comparison with other intervention methods. OBJECTIVE: This study aimed to examine the comparison of the effects of dynamic stretching, static stretching and percussive massage therapy on balance and physical performance in individuals. METHODS: The participants who were 18-25 years of age, able to perform performance tests, did not have any orthopedic surgery, did not have problems during running and sudden turning, and did not have a professional sports history were included in the study. Participants were assigned randomly to three groups as dynamic stretching (DS) (n= 16), static stretching (SS) (n= 16) and percussive massage therapy (PMT) (n= 16) groups. Horizontal jumping test, T drill test and balance measurements on a single leg with open and closed eyes of all participants were recorded before and after applications. RESULTS: When the values of the pre and post-treatment of all groups in the study were compared, significant improvements were observed in the t-test, horizontal jumping test and right/left foot balance with eyes open in DS group (p< 0.05). Significant improvements were observed in all values in the PMT group (p< 0.05). In the comparison of the differences between the groups, PMT group values were more significant than the SS group in all parameters. CONCLUSION: Percussive massage therapy would be an alternative that can be used to increase the performance and balance of individuals before exercise.

The Effects of Dry Needling on Hamstring Range of Motion: A Critically Appraised Topic.

CLINICAL SCENARIO: Hamstring range of motion (ROM) and the influence it has on injury risk is among great discussion in the literature. Hamstring injury may result from hamstring tightness, poor flexibility, or decreased ROM, and many argue that this can be prevented through various intervention strategies. In active populations, risk of further injury, pain, and complications throughout the kinetic chain can occur if minimal hamstring ROM is left untreated. One therapeutic intervention that has been applied to varying parts of the body to help improve function while relieving pain is dry needling (DN). This intervention includes the application of needles to structures to induce responses that might benefit healing and overall stimulation of a neurological response. In this review, the intent is to identify evidence and the effects of DN on hamstring ROM. CLINICAL QUESTION: What are the effects of DN on hamstring ROM? SUMMARY OF KEY FINDINGS: Among total 11 articles, 1 single-blinded randomized controlled trial and 2 double-blinded randomized controlled trials were included in this critically appraised topic. All 3 articles had inconclusive evidence to isolate the application of the DN intervention. There was insufficient evidence to identify if DN independently improved hamstring ROM; however, in combination with interventions such as exercise and stretch plans, there were improvements on ROM. CLINICAL BOTTOM LINE: DN does not significantly increase or decrease the ROM of the hamstrings. When combined with exercise and stretch plans, DN could increase ROM. STRENGTH OF RECOMMENDATION: The grade of B is recommended by the Strength of Recommendation Taxonomy for inconsistent or limited-quality patient-oriented evidence.

A scoping review of the different types of exercise programs proposed for the improvement of postural balance in adolescents with idiopathic scoliosis.

BACKGROUND: Adolescent idiopathic scoliosis (AIS), which is the most common type of scoliosis, is a progressive disease that occurs in children aged 10-16 years. Abnormal curvature in AIS provokes spinal asymmetry of the upper body alignment and might deteriorate postural balancing and control ability. OBJECTIVE: To evaluate the effect of exercise interventions on balance and postural stability in patients with adolescent idiopathic scoliosis. METHODS: Embase, Scopus, Pubmed (Medline) and Web of Science databases were searched using the terms idiopathic scoliosis, physiotherapy, and balance. The articles selected were published in English in peer-reviewed journals from 2012 to July 2022. RESULTS: Ten studies met the inclusion criteria. The PEDro scale values ranged from 2 to 6 (mean, 3.6), indicating a low level of scientific rigor. In the sample studies, spinal stabilization exercises were most often trialed (n= 3), followed by Schroth's exercise (n= 2), stretching and self-elongation exercise (n= 2), the exercise protocol of Blount and Moe, physiotherapeutic scoliosis-specific exercise, and proprioceptive neuromuscular facilitation exercise (all n= 1). CONCLUSIONS: Physical therapists will be able to apply hippotherapy, Schroth exercise, physiotherapy scoliosis-specific exercise, trunk stabilization, proprioceptive neuromuscular facilitation exercise, spinal stabilization exercise, core stabilization exercise, and body awareness therapy to manage balance impairments in patients with adolescent idiopathic scoliosis, and further studies are needed to provide stronger evidence.

Comparison of utilizing modified hold-relax, muscle energy technique, and instrument-assisted soft tissue mobilization on hamstring muscle length in healthy athletes: Randomized controlled trial.

INTRODUCTION: The hamstring muscle shortness is the primary risk factor for sports-related injuries. Numerous treatments are available for lengthening of hamstring muscle. The main purpose of this study was to compare the immediate effect of modified hold-relax, muscle energy technique (MET), and instrument assisted soft tissue mobilization-Graston techniques (IASTM-GT) on length of hamstring muscle in young healthy athletes. METHODS: 60 athletes comprising of 29 females and 31 males were recruited in the present study. Participants were allocated to 3 groups of IASTM-GT (N = 20, 13 male, 7 female), Modified Hold-relax (N = 20, 8 male, 12 female), and MET (N = 20, 7 male, 13 female). Active knee extension and passive straight leg raising (SLR), and toe touch test were performed before and immediately after the intervention by a blinded assessor. For the comparison of dependent variables across time, 3*2 repeated measure ANOVA was utilized. RESULTS: Interaction of group by time was significant for passive SLR (P < 0.001). Interaction of group by time was not significant for active knee extension (P = 0.17). The results showed that dependent variables increased significantly in all groups. The effect size (Cohen's d) in the groups of IASTM-GT, modified Hold-relax, and MET was 1.7, 3.17, and 3.12, respectively. CONCLUSION: Although the measures were improved in all groups, it seems that IASTM-GT can be used as a safe and efficient treatment, which can be a suitable candidate alongside modified hold-relax and MET for increasing the hamstrings muscle length in healthy athletes.

Acute effects of different proprioceptive neuromuscular facilitation stabilization techniques on the balance of elderly women.

AIM: To compare the acute effects of rhythmic stabilization (RS) and stabilizer reversal (SR) techniques of PNF on the balance of sedentary elderly women. METHODS: Women aged (≥70) were allocated into three groups: RS, SR and control (CR). The experimental groups (RS and SR) performed balance exercises with the addition of rhythmic stabilization techniques (RS group) or with stabilizers reversal (SR group) for 15 min. The CR group performed the exercises without adding the PNF stabilization techniques. Participants performed the Time Up and Go (TUG) test, the Functional Reach Test (FRT) and static and dynamic stabilometry pre and post intervention. Kruskal-Wallis and Mann-Whitney tests were used for comparison between groups and post hoc analysis, respectively, with p ≤ 0.05. For the effect size measurements, the r for Wilcoxon and Mann-Whitney signal were used. RESULTS: For functional tests intra-group analysis, a reduction in TUG time and an increase in FRT range (p ≤ 0.05) were observed in RS e SR groups. Stabilometry analysis showed a significant difference only for the RS group, with reduced average velocity of the centre of pressure (COP), and an increased in the left foot pressure. CONCLUSIONS: A single RS or SR session reduced the TUG time and the range distance in the FRT in elderly women. A single session of the RS technique was also able to reduce the mean velocity of the COP and the maximum pressure on the left foot. IMPACT: This study shows an easy-to-apply methods without additional materials that can help prevent falls in the elderly.

Hamstrings fascicle length and physical performance changes after a single bout of dynamic stretching or neurodynamic gliding in healthy young and older adults.

INTRODUCTION: The physiological and structural alterations have been less reported in response to dynamic stretching (DS) or neurodynamic nerve gliding (NG). Accordingly, this study investigated the changes in fascicle lengths (FL), popliteal artery velocity, and physical fitness in response to a single bout of DS or NG. METHODS: The study included 15 healthy young adults (20.9 ± 0.7 yrs) and 15 older adults (66.6 ± 4.2 yrs) who randomly performed three different interventions (DS, NG, and rest control) for 10 min and 3 days apart. The biceps femoris and semitendinosus FL, popliteal artery velocity, sit and reach (S&R), straight leg raise (SLR), and fast walking speed were measured before and immediately after the intervention. RESULTS: After NG intervention, S&R was largely greater by 2 cm (1.2, 2.8 cm) and 3.4 cm (2.1, 4.7 cm) with largely increased SLR angles of 4.9° (3.7°, 6.1°) and 4.6° (3.0°, 6.2°) with all p < 0.001 for the older adults and young groups, respectively. A similar magnitude improvement in the S&R and SLR testing was also seen for both groups after DS (p < 0.05). Moreover, no changes were seen in FL, popliteal artery velocity, fast gait speed, and age effect following all three intervention occasions. CONCLUSION: Stretching with DS or NG immediately increased flexibility, which appeared to be largely due to changes in stretch tolerance rather than an increase in fascicle length. Furthermore, age dependency in response to stretching exercise was not seen in the present study.

Effects of Static Contemporary Western Yoga vs. a Dynamic Stretching Exercise Program on Body Composition, Balance, and Flexibility.

ABSTRACT: Chapman-Lopez, TJ, Moris, JM, Petty, G, Timon, C, and Koh, Y. Effects of static contemporary western yoga vs. a dynamic stretching exercise program on body composition, balance, and flexibility. J Strength Cond Res 37(5): 1064-1069, 2023-Essentrics is a dynamic full-body stretching workout, which has recently earned its popularity in the field of yoga because of its potential for improvement in balance, flexibility, and weight loss while adding enjoyment to the workout without any discomfort and pain. However, the effects of Essentrics on overall health have not been well studied, particularly in a younger, physically healthy population. Thirty-five subjects (27 females and 8 males, age = 20.4 ± 0.2 years, and body mass index = 22.58 ± 0.55 kg·m-2) were assigned to 2 groups-contemporary western yoga (CWY, n = 20) and Essentrics (ESS, n = 15). Each group met 3 times per week for a total of 45-50 minutes per day for 6 weeks. Anthropometric measurements, body composition (dual-energy x-ray absorptiometry), flexibility (sit-and-reach), and balance (lower extremity Y-balance) were assessed before and after the 6-week program. The balance test included 3 reaches (anterior, posteromedial [PM], and posterolateral [PL] and composite reach distance). Each reach was averaged for the right and left sides and then normalized to leg length. Data were analyzed using an analysis of variance with repeated measures (p ≤ 0.05), and a post hoc test was performed for any significant interactions. There were no significant group differences between CWY and ESS in balance and flexibility. Following the 6-week yoga programs, balance was improved as follows: PM (87.13 ± 11.64 cm to 92.25 ± 9.91 cm, p = 0.001), PL (82.88 ± 11.28 to 88.62 ± 9.62 cm, p = 0.002), composite reach distance (CRD) (225.96 ± 27.17 to 238.26 ± 22.98 cm, p = 0.001), normalized PM (98.31 ± 11.68 to 104.27 ± 11.14%, p = 0.001), normalized PL (93.60 ± 11.98 to 100.15 ± 10.70%, p = 0.001), and normalized CRD (255.12 ± 27.89 to 269.21 ± 25.07%, p = 0.001). Flexibility was also improved from 51.42 ± 8.24 to 53.38 ± 7.04 cm (p = 0.010) following the 6-week workout programs. Total body fat percentage was significantly reduced only in the CWY group (24.44 ± 6.73 to 23.51 ± 6.32%, p = 0.002). Regardless of the type of stretching workout, both dynamic and static workouts improved flexibility and balance. Thus, individuals seeking to improve balance and flexibility can benefit from either dynamic or static yoga program.

Effects of traditional stretching versus self-myofascial release warm-up on physical performance in well-trained female athletes.

OBJECTIVE: The purpose of this study was to compare the acute effects of self-myofascial release (SMR) versus traditional stretching used as a part of warm-up on physical performance in well-trained female athletes. METHODS: Twenty-three participants (age, 21.8±1.73 years; experience in sport, 114.8±30.5 months) were recruited. Isokinetic peak torque and muscle endurance ratio were measured during knee extension and flexion at 60°/s and 180°/s. Jump height, reactive strength index, and leg stiffness were measured using a jump mat during a counter-movement jump. Hamstring flexibility was measured using a sit-and-reach test. Three interventions were performed by all athletes randomly within 72 hours intervals. RESULTS: The jump height and hamstring flexibility test scores improved significantly more after dynamic stretching (DS) as compared to SMR and static stretching (SS). The DS and SMR exercises were more effective than the SS exercises in terms of right and left knee muscle isokinetic strength both at 60°/s, and 180°/s. With regard to keeping muscular endurance ratio (%), SS exercises were found more effective than DS and SMR exercises for only the right knee at 180°/s, but not left knee muscle. CONCLUSION: Dynamic stretching and SMR showed better flexibility, strength, and jump performance than SS. Trainers and players may replace SS with DS and SMR to acutely improve muscle power, strength, and flexibility.

Effectiveness of physical therapy interventions on post-stroke spasticity: An umbrella review.

BACKGROUND: Post-stroke spasticity is often one of the primary impairments addressed in rehabilitation. However, limited guidance exists on the effectiveness of physical therapy (PT) interventions for post-stroke spasticity. OBJECTIVE: To evaluate the quality of evidence of PT interventions for post-stroke spasticity. METHODS: Ovid (Medline), Cochrane Library, CINAHL, Scopus, PEDro, and PROSPERO were searched to identify reviews based on the following criteria: 1) published between 2012 and 2021, 2) participants older than 18 years old, 3) post-stroke spasticity, 4) PT interventions, 5) clinical or neurophysiological measures of spasticity as primary outcomes. Assessment of Multiple Systematic Reviews 2 and the Grades of Recommendations Assessment, Development, and Evaluation assessed methodological quality. RESULTS: Eight articles were included in the analysis. No high-quality evidence was found. Moderate quality evidence exists for transcutaneous electrical nerve stimulation, neuromuscular electrical stimulation, resistance training, and lower extremity ergometer training with or without functional electrical stimulation. Low quality evidence exists for dynamic stretching, botulinum toxin with constraint-induced movement therapy, and static stretching using positional orthoses. CONCLUSION: Findings suggest that PT should prioritize a combination of active strategies over passive interventions, but further studies are needed prioritizing analyses of the movement system in managing post-stroke spasticity in conjunction with medical therapies.

Changes After a Conventional vs. an Alternative Therapy Program on Physical, Psychological, and Injury-Related Parameters in Male Youth Soccer Players With Patellar Tendinopathy During Return to Competition.

ABSTRACT: Niering, M and Muehlbauer, T. Changes after a conventional vs. an alternative therapy program on physical, psychological and injury-related parameters in male youth soccer players with patellar tendinopathy during return to competition. J Strength Cond Res 37(9): 1834-1843, 2023-Changes after a conventional (CON) vs. alternative (ALT) therapy program on physical, psychological, and injury-related or pain-related parameters in soccer players with patellar tendinopathy (PT) during return to competition were examined. Thirty-four male youth soccer players (15-16 years) with PT were randomly assigned to a CON ( n = 18) or ALT ( n = 16) program. The ALT program consisted of 60 minutes of balance training, eccentric and isometric exercises, static stretching, and a dual-task progression. The CON program consisted of 30 minutes of eccentric and isometric exercises and static stretching. Both programs were conducted until painlessness was reported during full training load. Assessments of muscle power (drop jump, jump and reach), change of direction speed (CODS) (acyclic sprint), speed (tapping, 30-m linear sprint), endurance (Yo-Yo intermittent recovery test level-1), the Achievement Motives Scale Sport, and injury-related or pain-related correlates were performed immediately, 6 weeks, 16 weeks, and 20 weeks after the respective therapy program. Players in the ALT group required a shorter program duration (ALT: 47.1 ± 15.6 days, CON: 58.2 ± 24.6 days) and achieved the same (muscle power, speed, endurance) or greater (CODS) improvements in physical performances, the same enhancements in psychological measures (achievement motives), and better values for injury-related or pain-related correlates (injury incidence, pain-related training interruptions). Results indicate that both programs effectively improve relevant outcome parameters in players with PT. The ALT therapy is more time efficient than the CON therapy. Therapists should consider this multimodal training program for effective treatment of athletes to shorten their return to competition time and minimize the risk of secondary injuries.

'It stretches your body but makes you feel good too': A qualitative study exploring young people's perceptions and experiences of yoga.

Whilst research suggests that yoga can positively impact physical and psychological wellbeing, understanding of youth's experiences is limited with no non-clinical studies in the UK. Ten focus groups explored perceptions and experiences of yoga among 35 youth (10-18 years). Inductive thematic analysis revealed that yoga was viewed as a holistic mind-body practice cultivating greater awareness and enhanced physical performance. Youth described yoga as providing tools that developed confidence, stress-management and emotional self-regulation. Social and relational impacts of yoga were highly valued. Despite the perceived biopsychosocial benefits of yoga, gendered and media representations of yoga may serve as a barrier to uptake.

Efficacy of proprioceptive neuromuscular facilitation in improving shoulder biomechanical parameters, functionality, and pain after axillary lymph node dissection for breast cancer: A randomized controlled study.

PURPOSE: Axillary lymph node dissection and radiotherapy have been associated with pain, physical symptoms, and decreased functional abilities in the upper extremity. This study aimed to evaluate the potential effects of the proprioceptive neuromuscular facilitation (PNF) technique on muscle strength, pain and functionality in this patient group in comparison with progressive resistance training (PRT). METHODS: The study was conducted with a randomized clinical trial design. Sixty-six women were included in the study and randomly divided into three groups: the PNF group (n = 22), the PRT group (n = 22), and the control group (n = 22). The participants were evaluated at the baseline and after eight weeks of treatment. Outcome measures were determined as pain (the Visual Analog Scale), upper extremity strength (isokinetic dynamometer), functionality (the Disabilities of the Arm, Shoulder and Hand questionnaire), and perception of change (the Global Rating of Change Scale). TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT05288036. RESULTS: The results showed statistically significant changes in both treatment groups in terms of shoulder flexors/extensors, abductor/adductors, internal/external rotators strength/power/endurance measurement, pain, and functionality (p < 0.05). Concerning functionality and perception of change, the PNF group had a statistically significantly higher improvement compared to the remaining two groups (p < 0.05). CONCLUSION: PNF is an effective technique in increasing upper extremity muscle strength, reducing pain during rest and activity, and improving functionality in patients receiving breast cancer treatment.

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.

Evaluation of the Effect of SPIDER System Therapy on Weight Shifting Symmetry in Chronic Stroke Patients-A Randomized Controlled Trial.

(1) Background: The Strengthening Program for Intensive Developmental Exercises and Activities for Reaching Health Capability (SPIDER) system is dedicated to patients with motor deficits resulting from damage to the peripheral or central nervous system (including post-stroke patients). It enables the conduct of forced-weight-bearing therapy to the lower limb affected by the paresis. In this study, the TYMO® measuring platform was used to quantify the impact of therapy using the SPIDER system and therapy that did not use this system. The TYMO® device is a portable posturography platform that monitors the tilting of the body's center of mass and reports the results of the rehabilitation process. (2) Objective: To evaluate the effect of therapy based on neurophysiological methods (proprioceptive neuromuscular facilitation (PNF), neurodevelopmental treatment according to the Bobath concept (NDT-Bobath)) and the SPIDER system on body weight transfer shifting, in post-stroke patients in the chronic phase, compared to therapy based on neurophysiological methods (PNF, NDT-Bobath), without the use of the SPIDER system. (3) Methods: This is a randomized controlled trial in which patients (n = 120; adults, post-ischemic stroke-first stroke episode, in chronic phase-up to 5 years after the stroke incident) were assigned to one of two groups: study, n = 60 (with therapy using PNF, NDT-Bobath methods and the SPIDER system); and control, n = 60 (with therapy using PNF and NDT-Bobath methods, without the SPIDER system). In patients in both groups, before and after the training (2 weeks of therapy), body weight distribution was measured on the TYMO® platform. (4) Results and Conclusions: The results of the statistical analysis demonstrated a greater reduction in the tilt of the body's center of mass in therapy using the SPIDER system, compared to therapy in which the system was not used.

Acute Effects of Static and Proprioceptive Neuromuscular Facilitation Stretching of the Plantar Flexors on Ankle Range of Motion and Muscle-Tendon Behavior in Children with Spastic Cerebral Palsy-A Randomized Clinical Trial.

Stretching is considered a clinically effective way to prevent muscle contracture development in children with spastic cerebral palsy (CP). Therefore, in this study, we assessed the effects of a single session of proprioceptive neuromuscular facilitation (PNF) or static stretching (SS) on ankle joint range of motion (RoM) and gastrocnemius muscle-tendon behavior in children with CP. During the SS (n = 8), the ankle joint was held in maximum dorsiflexion (30 s). During the PNF stretching (n = 10), an isometric contraction (3-5 s) was performed, followed by stretching (~25 s). Ten stretches were applied in total. We collected data via dynamometry, 3D motion capture, 2D ultrasound, and electromyography, before and after the stretching sessions. A mixed ANOVA was used for the statistical analysis. Both ankle RoM and maximum dorsiflexion increased over time (F(1,16) = 7.261, p < 0.05, η² = 0.312; and F(1,16) = 4.900, p < 0.05, η² = 0.234, respectively), without any difference between groups. An interaction effect (F(1,12) = 4.768, p = 0.05, η² = 0.284) was observed for muscle-tendon unit elongation (PNF: -8.8%; SS: +14.6%). These findings suggest a positive acute effect of stretching on ankle function. However, SS acutely increased muscle-tendon unit elongation, while this decreased after PNF stretching, indicating different effects on the spastic muscles. Whether PNF stretching has the potential to cause positive alterations in individuals with CP should be elucidated in future studies.
