RESUMO
Chronic rhinosinusitis (CRS) is one of the most common conditions all over the world. The purpose of this study was to investigate the effects of low-level laser therapy (LLLT) in patients with CRS. Fourteen adult patients with CRS participated in this single-blind, sham-controlled clinical trial (12 male, mean age 40 years). Patients received five successive sessions of sham laser followed by five successive sessions of real laser after 2 days. Ga-Al-As laser of 830 nm in a continuous mode at a power output of 30 mW and energy dose of 1 J was applied on the cheeks and the forehead for the maxillary and frontal sinuses, respectively. Laser was delivered on six points over each sinus, each point for 33 s. Four measurements were taken. The total symptom score (TSS) was calculated as the primary outcome measure. The effects of LLLT on TSS were evaluated by using repeated measure ANOVA. The percentage improvement of real laser and sham laser was compared by Wilcoxon signed ranked test. Cohen's d was used to calculate the effect size. Total symptom score significantly improved after real laser (p = 0.015, Cohen's d = 0.69). The percentage improvement for real laser (34.12 ± 46.43) was significantly better than the sham laser (5.02 ± 37.34, Z = - 2.23, p = 0.026). No significant improvements were observed after sham laser. This study indicates that five-session active LLLT when compared with sham is effective in the treatment of CRS symptoms.

BACKGROUND: Chronic nonspecific low back pain (LBP) is one of the common health issues. Hamstring tightness contributes to the development of LBP. This study aimed to investigate the acute and short-term effects of deep dry needling (DN) in patients with chronic nonspecific LBP and hamstring muscle tightness. METHODS: A single-group pretest-posttest clinical study design was followed. The outcome measures were the visual analog scale (VAS), passive knee extension (PKE) test, finger-floor distance (FFD) test, and functional rating index (FRI). Patients underwent one session of deep DN of three points on both hamstring muscles, each point for one minute. Patients were assessed before (T0), immediately after (T1), and one week after DN (T2). The FRI was assessed at T0 and T2. RESULTS: Ten women with a mean age of 21.1 years (SD = 1.6) participated in the study. Significant large effect sizes in VAS pain reduction (d = 1.25) and PKE hamstring tightness were obtained (hamstring: right, d = 0.82; left, d = 0.88) at T2. Medium effect sizes were obtained for FFD (d = 0.45) and FRI (d = 0.72) at T2. CONCLUSION: A single session of deep DN improved pain and function and increased hamstring flexibility. This pilot study supports the use of DN in patients with LBP and hamstring tightness; however, future research with a rigorous study design of randomized controlled trial is required to confirm the findings. This trial is registered with IRCT20180511039612N1.

BACKGROUND: The Western Ontario Meniscal Evaluation Tool (WOMET) is the only questionnaire available to assess quality of life in patients with isolated meniscal injuries. The aims of this study were to prepare the Persian version of the WOMET (PWOMET) and validate it in Iranian patients with isolated meniscal tears. METHODS: In the first stage, the English version of WOMET was translated into Persian. Content validity, and qualitative and quantitative (impact score) face validity were tested by specialists and in a sample of 30 patients. In the second stage, PWOMET was assessed for the evaluation of psychometric properties in 100 patients with isolated meniscal injury and 50 healthy people based on the COSMIN checklist. Construct validity was tested based on structural validity (factor analysis) and hypothesis testing. Correlation with the total scores on the SF-36, IKDC and KOOS were used for concurrent criterion validity. Test-retest reliability and internal consistency were calculated using intraclass correlation coefficient (ICC) and Cronbach's alpha, respectively. In addition the standard error of measurement (SEM) and smallest detectable change were calculated. Interpretability was investigated as the ceiling and floor effects and minimal important difference. RESULTS: The PWOMET had acceptable qualitative face validity and content validity. The impact score (quantitative face validity) was more than 1.5 for all items. For construct validity, structural validity (factor analysis) and hypothesis testing ability were confirmed. Correlations between the PWOMET total score and IKDC, SF-36, KOOS scores were 0.61, 0.54 and 0.63, respectively (p < 0.001), thus confirming concurrent criterion validity. The intraclass correlation coefficient, Cronbach's alpha, SEM and smallest detectable change for the PWOMET were 0.73, 0.89, 9.43 and 26.13, respectively. The PWOMET had no ceiling or floor effects, and minimal important difference was 9.07. CONCLUSION: The PWOMET provides valid and reliable scores for assessment of the quality of life in patients with isolated meniscal injury.

CONTEXT: There are numerous studies on the benefits of dry needling (DN) for pain relief. No studies exist examining the effects of DN on hamstring flexibility. OBJECTIVE: To determine the immediate effects of DN on hamstring flexibility in healthy subjects with shortened hamstrings. DESIGN: A single-blinded, pretest-posttest clinical pilot study. SETTING: A university physiotherapy clinic. SUBJECTS: A total of 15 healthy subjects (female = 11; age = 23.26 [4.3] y) with shortened hamstrings participated in this study. INTERVENTION: Subjects received a single session of DN. Three locations on the hamstring muscle group were needled, each for 1 minute. MAIN OUTCOME MEASURES: The active knee extension test, muscle compliance, passive peak torque, and stretch tolerance were measured at baseline, immediately, and 15 minutes after DN. RESULTS: There were statistically significant improvements in all outcome measures immediately after DN and at the 15-minute follow-up. The effect sizes for all outcome measures were large (Cohen's d ≥ 0.8). No serious adverse events were observed with DN. CONCLUSIONS: This is the first study that demonstrates the beneficial effects of DN on hamstring flexibility, muscle compliance, and stretch tolerance without added stretching. The beneficial effects of DN should encourage clinicians to use DN as a novel strategy for increasing muscle flexibility.

CONTEXT: Hamstring muscle tightness is one of the most common problems in athletic and healthy people. Dry needling (DN) was found to be an effective approach for improving muscle flexibility, but there is no study to compare this approach with static stretching (SS) as a common technique for the increase of muscle length. OBJECTIVE: To compare the immediate effects of DN and SS on hamstring flexibility in healthy subjects with hamstring tightness. STUDY DESIGN: A single-blind randomized controlled trial. SETTING: A musculoskeletal physiotherapy clinic at Tehran University of Medical Sciences. SUBJECTS: Forty healthy subjects (female: 32, age range: 18-40 y) with hamstring tightness were randomly assigned into 2 groups of DN and SS. INTERVENTION: The DN group received a single session of DN on 3 points of the hamstring muscles, each for 1 minute. The SS group received a single session of SS of the hamstrings, consisting of 3 sets of 30-second SS with a 10-second rest between sets in the active knee extension test (AKET) position. MAIN OUTCOME MEASURES: The AKET, muscle compliance, passive peak torque, and stretch tolerance were measured at the baseline, immediately, and 15 minutes after the interventions. RESULTS: Improvements in all outcomes was better for the DN group than for the SS group. DN increased muscle compliance significantly 15 minutes after the intervention, but it did not improve in the SS group. CONCLUSION: DN is effective in improving hamstring flexibility compared with SS. One session of DN can be an effective treatment for hamstring tightness and increase hamstring flexibility. The improvements suggest that DN is a novel treatment for hamstring flexibility.

BACKGROUND: This study aimed to compare the effects of therapeutic ultrasound (US) and radial extracorporeal shock wave therapy (rESWT) in the treatment of plantar flexor spasticity after stroke. MATERIALS AND METHODS: In this prospective, single-blind, randomized clinical trial, 32 patients (age range 42-78 years; male 19) with stroke were randomly divided into two groups: The US group (nâ¯=â¯16) received the continuous ultrasound, intensity 1.5 w/cm2, frequency 1 MHz, and duration 10 minutes. The rESWT group (nâ¯=â¯16) was treated with rESWT, 0.340 mJ/mm2, 2000 shots. Both groups received the treatments for 1 session. The H-reflex tests of Hmax/Mmax ratio and H-reflex latency, the Modified Modified Ashworth Scale (MMAS), active range of motion (AROM), passive range of motion (PROM), passive plantar flexor torque (PPFT), and the timed "up and go" test (TUG) were blinded assessed at baseline (T0), immediately post-treatment (T1), and one hour follow-up (T2). RESULTS: The H-reflex tests did not improve across the groups. However, the MMAS spasticity scores, AROM and PROM, PPFT, and TUG improved significantly within groups. The results found no significant differences between groups for all outcome measures. CONCLUSIONS: The US and rESWT had similar effects, and the rESWT was not more effective than the US in improving ankle plantar flexor spasticity after stroke.

The reliability of the Modified Tardieu Scale (MTS) has not been examined in patients with multiple sclerosis (MS). This study aimed to assess intra-rater reliability of the MTS in the assessment of lower limb spasticity in patients with MS. Data from 30 patients with MS (18 women, mean age = 41.5) were used to assess intra-rater reliability. An inexperienced physiotherapist in the scale randomly examined the hip adductors, knee extensors, and ankle plantar flexors on each subject twice with at least a 7-day interval. Kappa statistics (κ) were calculated for MTS quality of muscle reactions. Intraclass correlation coefficients (ICCagreement) and smallest detectable change (SDC) were calculated for R2, R1, and R2-R1. Qualitative rating of spasticity demonstrated moderate or good agreement, with an overall moderate κ of 0.72. Intra-rater reliability for all angle components of MTS was poor to good (ICCagreement range 0.45-0.83). The SDC for all the MTS components across the muscle groups was unacceptably large (range 14.6-55.6). Results did not establish good intra-rater reliability for the MTS when assessing lower limb muscle spasticity in patients with MS by a physiotherapist with no previous experience in the scale and with limited training.

CONTEXT: Whole-body vibration (WBV) is a type of weight-bearing exercise used in the field of sport and rehabilitation. There is no study on the effects of WBV on muscle recovery after a fatiguing activity. OBJECTIVE: To determine the effects of a single WBV session on lower-extremity fatigue. DESIGN: Randomized controlled pilot study. SETTING: University Physiotherapy Clinic. SUBJECTS: A total of 13 healthy young men volunteered to participate in this study. Subjects were randomly assigned into the WBV group (n = 7, mean age: 21 y) or control group (CG; n = 6, mean age: 20 y). INTERVENTION: Subjects in the WBV group participated in a single-session WBV (30 Hz, amplitude 4 mm, 2 min) after lower-extremity fatigue. MAIN OUTCOME MEASURES: Peak force of quadriceps muscle, single leg hop test, and Y-test were measured before inducing muscle fatigue (T0), immediately after completing the fatigue protocol (T1), after WBV (T2), and 15 min following the application of WBV (T3). The same method was applied in the CG while the WBV machine was turned off. RESULTS: Repeated-measure ANOVA revealed no significant differences between groups in any of the outcomes. CONCLUSIONS: The findings indicated that WBV was not effective in the recovery of lower-extremity fatigue in healthy young men.

BACKGROUND: The aim of this study is evaluation of the validity and reliability of the Persian version of Knee Injury and Osteoarthritis Outcome Score (KOOS) in patients with isolated meniscus injury. MATERIALS AND METHODS: One hundred people with isolated meniscal injury (29 females and 71 males with a mean age ± standard deviation [SD] = 32.37 ± 9.97 years) and fifty normal people with no knee problems (34 females and 16 males with a mean age ± SD = 28.42 ± 8.84 years) participated in this study. In patients, the duration of meniscus injury ranged from 1 month to 4 years. For evaluation of discriminate validity, we compared scores of KOOS questionnaire between patients and healthy people, and for concurrent validity, in addition to filling KOOS questionnaire, patients completed Short Form (SF-36) questionnaire, test-retest reliability with intraclass correlation coefficient) ICC), and internal consistency with Cronbach's alpha was calculated. RESULTS: Mean scores of patients (49.51 ± 17.13) and healthy people (86.01 ± 13.44) were different significantly (P < 0.001). The correlation between total score of SF-36 and KOOS was significant (r = 0.77, P < 0.001). ICC was 0.80 (ranged from 0.64-0.75) and Cronbach's alpha was 0.96 (ranged from 0.72 to 0.94). CONCLUSION: The Iranian version of KOOS is a reliable and valid tool for patients with isolated meniscus injury, so the clinicians and investigators may use this questionnaire in clinical settings and their researches.
RESUMO
PURPOSE: To cross-culturally adapt the Achilles tendon Total Rupture Score (ATRS) to Persian language and to preliminary evaluate the reliability and validity of a Persian ATRS. METHODS: A cross-sectional and prospective cohort study was conducted to translate and cross-culturally adapt the ATRS to Persian language (ATRS-Persian) following steps described in guidelines. Thirty patients with total Achilles tendon rupture and 30 healthy subjects participated in this study. Psychometric properties of floor/ceiling effects (responsiveness), internal consistency reliability, test-retest reliability, standard error of measurement (SEM), smallest detectable change (SDC), construct validity, and discriminant validity were tested. Factor analysis was performed to determine the ATRS-Persian structure. RESULTS: There were no floor or ceiling effects that indicate the content and responsiveness of ATRS-Persian. Internal consistency was high (Cronbach's α 0.95). Item-total correlations exceeded acceptable standard of 0.3 for the all items (0.58-0.95). The test-retest reliability was excellent [(ICC)agreement 0.98]. SEM and SDC were 3.57 and 9.9, respectively. Construct validity was supported by a significant correlation between the ATRS-Persian total score and the Persian Foot and Ankle Outcome Score (PFAOS) total score and PFAOS subscales (r = 0.55-0.83). The ATRS-Persian significantly discriminated between patients and healthy subjects. Explanatory factor analysis revealed 1 component. CONCLUSION: The ATRS was cross-culturally adapted to Persian and demonstrated to be a reliable and valid instrument to measure functional outcomes in Persian patients with Achilles tendon rupture. LEVEL OF EVIDENCE: II.

BACKGROUND: The purpose of the study was to determine whether the Persian Core Outcome Measures Index (PCOMI) is reliable and valid in patients with chronic low back pain (CLBP). METHODS: The Persian COMI was developed using forward-backward translational method. Subjects were100 patients with CLBP. Patients completed the PCOMI, Persian functional rating index, and visual analog scale. Fifty patients completed the PCOMI for the second time after 7days to evaluate test-retest reliability. Fifty healthy subjects participated to assess discriminant validity. RESULTS: There was no ceiling or floor effect. Cronbach's alpha was 0.85. The construct validity coefficient was 0.72. The ICCagreement for test-retest reliability was 0.86. Pearson correlation for criterion validity was 0.70. The PCOMI discriminated between patients and healthy subjects. The standard error of measurement and the smallest detectable change was 0.75 and 2.1, respectively. Factor analysis extracted 1 component. CONCLUSIONS: The results support the reliability and validity of the PCOMI for assessing patients with CLBP.

PURPOSE: To translate, culturally adapt, and validate the simple shoulder test (SST) and Oxford Shoulder Score (OSS) into Persian language using a cross-sectional and prospective cohort design. METHODS: A standard forward and backward translation was followed to culturally adapt the SST and the OSS into Persian language. Psychometric properties of floor and ceiling effects, construct convergent validity, discriminant validity, internal consistency reliability, test-retest reliability, standard error of the measurement (SEM), smallest detectable change (SDC), and factor structure were determined. RESULTS: One hundred patients with shoulder disorders and 50 healthy subjects participated in the study. The PSST and the POSS showed no missing responses. No floor or ceiling effects were observed. Both the PSST and POSS detected differences between patients and healthy subjects supporting their discriminant validity. Construct convergent validity was confirmed by a very good correlation between the PSST and POSS (r = 0.68). There was high internal consistency for both the PSST (α = 0.73) and the POSS (α = 0.91 and 0.92). Test-retest reliability with 1-week interval was excellent (ICCagreement = 0.94 for PSST and 0.90 for POSS). Factor analyses demonstrated a three-factor solution for the PSST (49.7 % of variance) and a two-factor solution for the POSS (61.6 % of variance). The SEM/SDC was satisfactory for PSST (5.5/15.3) and POSS (6.8/18.8). CONCLUSIONS: The PSST and POSS are valid and reliable outcome measures for assessing functional limitations in Persian-speaking patients with shoulder disorders.

Importance: Neuromodulation may be one of the underlying mechanisms of dry needling (DN); however, the mechanism has not yet been fully clarified. Objective: This randomized controlled trial is designed to evaluate DN stimulation of the tibialis anterior and peroneus longus muscles in chronic ankle instability (CAI) and healthy subjects, employing functional magnetic resonance imaging (fMRI). Design: Clinical study protocol, SPIRIT compliant. Setting: Brain Mapping Laboratory. Population: A total of thirty participants aged between 18 and 40 years old will be included in this study. Twenty healthy participants will be randomized into 2 groups (real DN and sham DN). Ten patients with CAI will also be recruited to the third group and receive only real DN for comparison. Exposures: Real and sham DN. Main Outcomes and Measures: The voxel count, coordinates of peak activation, and peak intensity will be obtained as primary outcomes to report brain map activation. Measurements will be taken before, during, and after DN treatment. The strength of the ankle dorsiflexors, active dorsiflexion range of motion, and McGill pain questionnaire short-form will be used as secondary outcome measures. Results: The results from this study will be published in peer-reviewed journals and disseminated as presentations at national and international congresses. Conclusion: This trial will explore brain responses to real and sham DN in healthy participants and to real DN in CAI patients. Overall, our results will provide preliminary evidence of the neural mechanism of DN.

BACKGROUND: The positive contribution of dry needling (DN) in conjunction with exercise therapy for patients with stroke and spasticity remains uncertain. OBJECTIVE: To examine the effects of DN combined with exercise therapy on wrist flexor spasticity and motor function in patients with stroke. METHODS: Twenty-four participants with stroke were randomly assigned to either the DN and exercise therapy group or the DN alone group. Assessments were conducted at baseline, after the 4th treatment session, and 3 weeks post-treatment. RESULTS: A significant Group×Time interaction was observed for wrist active range of motion (ROM) (Pâ=â0.046), favoring the DN with exercise therapy group (â¼10° at baseline, â¼15° immediately after the 4th session, and 15.4° at follow-up). The improvements in spasticity, passive ROM, and H-reflex latency were sustained during follow-up. However, there were no significant between-group differences in any outcome at any measurement time point. CONCLUSION: The combined DN and exercise therapy did not exhibit superiority over DN alone concerning spasticity severity and motor function. However, it demonstrated additional advantages, particularly in improving motor neuron excitability and wrist passive extension.

No study has evaluated the effects of dry needling on Paralympic athletes. Therefore, in this study, we will evaluate the effect of dry needling on lower limb spasticity and motor performance, as well as the range of motion of Paralympic athletes. The study will be a triple-blinded, randomised controlled trial. Twenty-four athletes aged 18-45 in T35-T38 groups of the International Paralympic Committee classification will be included in the study. Twelve participants will receive dry needling of the quadriceps and gastrocnemius muscles, and 12 will receive placebo treatment with sham needles at similar points. We will assess the spasticity of the quadriceps and gastrocnemius muscles using the Modified Ashworth Scale, evaluate motor function using the Selective Control Assessment of the Lower Extremity Scale and measure ankle range of motion (ROM) with a goniometer. Considering our hypothesis, the athletes who will undergo the dry needling are supposed to achieve better improvements in spasticity, ROM and motor performance. This study can provide useful information to help better decide on managing complications in Paralympics and its long-term outcomes, to cover the current lack in the literature.
RESUMO
Introduction: Falling is a serious problem for all ages. There are several tests to assess balance. Mini-BESTest and brief-BESTest are balance tests for which there are no normative values for Iranian people. We aimed to provide the normative values of mini-BESTest and brief-BESTest among healthy Iranian adults. Methods: A cross-sectional study was designed. Three hundred healthy adults (150 males and 150 females) in six age groups (18-29, 30-39, 40-49, 50-59, 60-69, +70 years) completed the tests using Persian mini-BESTest and brief-BESTest. Normative values were calculated for age groups. Results: Normative values of mini-BESTest and brief- BESTest decreased significantly with age (from 27 to 21.9 for mini-BESTest and from 22.9 to 15.4 for brief BESTest). There were no significant differences between genders except for females in 30-39 and 40-49 years age groups which scored better on brief-BESTest and mini-BESTest, respectively. Males had significantly scored better in brief- BESTest in 60-69 and ≥ 70 age groups. Conclusions: The normative values of the mini-BESTest and brief-BESTest provided for healthy Iranian adults can help clinicians when assessing subjects with balance dysfunction.

PRIMARY OBJECTIVE: To evaluate the reliability of the Modified Tardieu Scale (MTS) in the measurement of ankle plantarflexor spasticity in patients after stroke. RESEARCH DESIGN: Inter- and intra-rater reliability study. INTERVENTIONS: Not applicable. METHODS AND PROCEDURES: Adult patients after stroke participated. Patients were tested by two raters for inter-rater reliability. Patients were re-tested by one rater at least 1 week later for intra-rater reliability. The plantarflexors on the hemiparetic side were tested. MAIN OUTCOMES AND RESULTS: The ICCs of inter and intra-rater reliability across all components of MTS were moderate and moderately high (range 0.40-0.71). Inter- and intra-rater reliability for the dynamic component of spasticity (R2-R1) were moderate (ICC = 0.57 and 0.40, respectively). The difference between the two raters for R2 was statistically significant (p = 0.001). CONCLUSIONS: The reliability of the Modified Tardieu Scale in the measurement of ankle plantarflexor spasticity in adult patients after stroke was insufficient for routine use in clinical settings and research.

BACKGROUND: Determining the optimal number of dry needling (DN) sessions to satisfactorily treat a stroke patient with spasticity is important from both clinical and economic perspective. OBJECTIVE: To explore the effects of one versus three sessions of DN on spasticity of the wrist flexors and motor recovery after stroke. METHODS: In this single-blind randomized clinical trial, 24 patients were randomly and equally divided into two groups: one group received one session of DN, while the other group received three sessions of DN in one week. Both groups received one minute of DN of the flexor carpi radialis and flexor carpi ulnaris. The outcome measures were the Modified Modified Ashworth Scale (MMAS), passive resistance torque (PRT), wrist active and passive extension range of motion (ROM), and the Brunnstrom Stages of Stroke Recovery (BSSR) measured before, immediately after, and one week after the last DN session. RESULTS: Both groups demonstrated a significant improvement in all outcomes (p < .05). The MMAS scores in both groups meaningfully improved (p < .001). No significant differences were found between the two groups; however, a significant time-by-group interaction was observed for the PRT (p = .02; Cohen's d = 0.23-0.73), wrist active extension ROM (p = .001; Cohen's d = 0.37-0.67), and wrist passive extension ROM (p = .02; Cohen's d = 0.32-1.30). The BSSR significantly improved from 3 to 4 in both groups (p < .001). CONCLUSION: Administering three sessions of DN can effectively improve spasticity and motor function after stroke.
RESUMO
Uni-hemispheric concurrent dual-site anodal transcranial direct current stimulation (UHCDS a-tDCS) of the primary motor cortex (M1) and the dorsolateral prefrontal cortex (DLPFC) may enhance the efficacy of a-tDCS after stroke. However, the cellular and molecular mechanisms underlying its beneficial effects have not been defined. We aimed to investigate the effect of a-tDCSM1-DLPFC on brain metabolite concentrations (N-acetyl aspartate (NAA), choline (Cho)) in stroke patients using magnetic resonance spectroscopy (MRS). In this double-blind, sham-controlled, randomized clinical trial (RCT), 18 patients with a first chronic stroke in the territory of the middle cerebral artery trunk were recruited. Patients were allocated to one of the following two groups: (1) Experimental 1, who received five consecutive sessions of a-tDCSM1-DLPFC M1 (active)-DLPFC (active). (2) Experimental 2, who received five consecutive sessions of a-tDCSM1-DLPFC M1 (active)-DLPFC (sham). MRS assessments were performed before and 24 h after the last intervention. Results showed that after five sessions of a-tDCSM1-DLPFC, there were no significant changes in NAA and Cho levels between groups (Cohen's d = 1.4, Cohen's d = 0.93). Thus, dual site a-tDCSM1-DLPFC did not affect brain metabolites compared to single site a-tDCS M1.
RESUMO
Background: : Dry needling (DN) is recommended as a therapeutic modality for various neuromusculoskeletal disorders. No study has been performed on the impact of DN on arthrogenic muscle inhibition (AMI) after anterior cruciate ligament reconstruction (ACLR). This study protocol is aimed to investigate the impacts of DN on AMI of quadriceps femoris, corticomotor, and spinal reflex excitability in patients with ACLR. Methods: : A double-blind, between-subject, randomized, controlled trial will be conducted to measure changes in AMI after DN. Twenty-four subjects with ACLR will be recruited to receive a DN or a sham DN, providing that they met the inclusion criteria. Three sessions of DN on the quadriceps femoris will be applied during a one-week period. The primary outcome measures are the active motor threshold, motor evoked potential, and Hmax - Mmax ratio. The secondary outcomes are the International Knee Documentation Committee subjective knee form questionnaire score and maximum quadriceps isometric torque. Data will be collected at baseline, immediately after the first session, after the third session, and at the one-month follow-up visit. Discussion: : The results of this study will provide preliminary evidence regarding the effects of DN on AMI of quadriceps femoris in patients with ACLR.
