Editorial Commentary: Physical Therapy Alone May Not Successfully Treat Patients With Hip Pain and Large α Angles or Decreased Femoral Anteversion Combined With Femoroacetabular Impingement Syndrome.

Understanding the relation between spinopelvic (lumbopelvic) tilt and femoracetabular impingement syndrome (FAIS) is complex, and determining the optimal patient parameters that lead to successful nonoperative management is vital. Physical therapy (PT) focusing on core and posterior chain strengthening is often successful. PT can change the posterior tilt of the pelvis by 5° to 10°, allowing increased range of motion (ROM) and decreased impingement of the hip. However, PT does not change cam anatomy. Thus, PT alone may not sufficiently increase ROM in patients with cam-type impingement and large α angles or limited femoral anteversion. Pelvic compensation may lead to successful nonoperative management of FAIS, but not in all patients. Large-cam, high-flexion athletes with chronic hip pain should try PT. Yet, while some patients with large cam lesions may improve without surgery if femoral version and/or pelvic tilt ROM can be increased, surgery should not be excessively delayed in patients with poor prognostic factors for nonoperative management.

Exercise compared to a control condition or other conservative treatment options in patients with Greater Trochanteric Pain Syndrome: a systematic review and meta-analysis of randomized controlled trials.

OBJECTIVES: To estimate the effectiveness of exercise at end of treatment and long-term follow-up compared to a control condition or other conservative treatments in patients with Greater Trochanteric Pain Syndrome (GTPS). METHODS: Databases were searched September 2021 and updated September 2023. Randomized controlled trials (RCT) comparing exercise interventions for patients with GTPS, to a control condition; corticosteroid injection; shock wave therapy; or other types of exercise programs were included. Risk of bias was assessed using the ROB2 tool. Meta-analyses were performed using a random-effects model. The certainty of the evidence was rated by the GRADE approach. RESULTS: Six RCTs including a total of 733 patients with GTPS were included. Three trials compared exercise to sham exercise or wait-and-see control groups, two trials compared exercise to corticosteroid injection, two trials compared exercise to shockwave therapy, and one trial compared exercise to another type of exercise. Meta-analyses showed that in the long term, exercise slightly reduces hip pain and disease severity, while slightly improving patient-reported physical function and global rating of change compared to a control condition. No serious adverse events were reported. Compared to corticosteroid injection, exercise improves long-term global rating of change. CONCLUSION: The current evidence supports a strong recommendation for exercise as first line treatment in patients clinically diagnosed with GTPS. Compared to corticosteroid injection, exercise is superior in increasing the likelihood that a patient experiences a meaningful global improvement. These results are based on few trials and a moderate number of patients. REGISTRATION: This review was prospectively registered in the PROSPERO database of systematic reviews (ID: CRD42021261380).

Effectiveness and safety of tendon-bone-setting in postpartum women with sacroiliac joint pain: A retrospective multicenter study.

Sacroiliac joint (SIJ) pain leads to abnormal joint loading, and is a key risk factor for joint degeneration. This study aimed to determine the effect of tendon-bone-setting on postpartum women with SIJ pain. Multicenter retrospective review of medical records and electroencephalography reports in 10 academic medical centers. 328 postpartum women with sacroiliac joint pain were divided into 2 groups according to the methods of therapy. Group (A) (n = 203) received acupuncture combined with tendon-bone-setting for twenty days, whereas group (B) (n = 125) received only the same acupuncture for twenty days. The outcome measures were the mean values of numeric pain rating scale (NPRS), present pain intensity (PPI) scale, visual analog scale (VAS) and Japanese orthopedic association (JOA) score to evaluate pain intensity, oswestry disability index (ODI), quebec back pain disability scale (QBPDS), active straight leg raise (ASLR) and back pain function scale (BPFS) to evaluate the functional disability, pressure pain thresholds (PPT) at 5 chosen points in the sacroiliac joint region to assess pain sensitivity. All of them were evaluated before and after treatment. The effectiveness from short to long term, as well as safety was assessed in this study. A comparison of the 2 groups after treatment showed statistically significant increases in the mean values of BPFS, JOA and PPT at the 5 chosen points (P < .05), as well as significant reductions in the scores of QBPDS, ODI, ASLR, NPRS, VAS and PPI (P < .05) in favor of group (B). In addition, after treatment for 2 weeks, the considered effective rate in the group (A) was significantly higher than that in the group (B) (P < .05). Also, the cumulative incidence of pain relief at 24 months in the group (A) was greater compared with the group (B) as determined by Kaplan-Meier analysis (P < .05). Interestingly, none serious adverse event for the participants was reported. Tendon-Bone-Setting is effective and safe in treating sacroiliac joint pain for the postpartum women patients in the short and long terms through decreasing pain sensitivity and intensity, as well as improving functional ability.

Efficacy of trigger point dry needling on pain and function of the hip joint: a systematic review of randomized clinical trials.

OBJECTIVE: The objective of this study was to assess the evidence for the impact of dry needling (DN) on hip pain and function. METHODS: Medline/PubMed, Embase, Scopus, Web of Science and Cochrane CENTRAL databases were searched systematically through June 2022 for randomized clinical trials (RCTs) investigating the impact of DN on hip pain and function. Version 2 of the Cochrane risk-of-bias tool for randomized trials (RoB 2) was used to assess risk of bias. Descriptive analysis was conducted to explain the outcomes and adverse events of DN in hip joint diseases. Meta-analysis was not feasible due to significant heterogeneity. RESULTS: A total of seven eligible studies (including 273 patients) were included out of 2152 screened records. Five studies were in participants with hip osteoarthritis (OA; n = 3), greater trochanteric pain syndrome (GTPS; n = 1) or piriformis syndrome (n = 1); the other two studies were conducted in healthy athletes (n = 2). Two articles assessed changes in participants' short-term visual analog scale (VAS) scores (<1 week), one of which showed that DN significantly reduced pain (P < 0.05). One-week VAS scores were analyzed in three studies, all of which demonstrated reduced scores following DN (P < 0.05). Hip range of motion (ROM) and muscle force were also improved following DN. No serious side effects were reported. CONCLUSION: DN may be safe and effective at relieving hip pain and improving hip function. DN performs significantly better than several different types of control intervention (including sham DN, no treatment, corticosteroid injections and laser). Strong evidence (high degree of certainty around the results) is lacking, and future studies should ideally use longer follow-up periods and larger sample sizes.

Effect of whole-body cryotherapy versus placebo cryotherapy on joint pain induced by aromatase inhibitors in women with early stage breast cancer: a randomised clinical trial.

INTRODUCTION: Hormone therapy (HT) is a major adjuvant treatment for breast cancer. Despite their effectiveness, aromatase inhibitors can cause several side effects, including arthralgia in 35%-50% of patients. These side effects frequently lead to the premature discontinuation of HT. Whole-body cryotherapy (WBC) can be used for managing arthritic pain. The primary objective of this study will be to evaluate the effect of WBC on aromatase-induced joint pain, compared with placebo cryotherapy, in patients with hormone-dependent breast cancer receiving adjuvant aromatase inhibitors. The secondary objectives will be to evaluate WBC safety and its effect on analgesic consumption, HT adherence and quality of life. METHODS AND ANALYSIS: In this randomised, placebo-controlled, double-blinded clinical trial, 56 patients with aromatase inhibitor-induced joint pain and a Brief Pain Inventory-Short Form (BPI-SF) score ≥3 for the worst pain experienced in the previous week will be randomised into the WBC or placebo cryotherapy arm (10 sessions in each group). The primary outcome will be the BPI-SF score at week 6 post-treatment. The secondary outcomes will include the BPI-SF scores at months 3 and 6 post-treatment, the BPI-SF pain severity index and pain interference index, the Health Assessment Questionnaire score, the number of days of aromatase inhibitor treatment and analgesic consumption in the 15 days before the visits at week 6 and months 3 and 6 after cryotherapy. The incidence of adverse events will also be investigated. ETHICS AND DISSEMINATION: Ethics approval was obtained from the Ethics Committee Est IV of Hospital Civil, Strasbourg, France. Protocol V.5 was approved in December 2022. The results will be disseminated in a peer-reviewed journal and presented at international congresses. TRIAL REGISTRATION NUMBER: NCT05315011.

Ozone alleviates MSU-induced acute gout pain via upregulating AMPK/GAS6/MerTK/SOCS3 signaling pathway.

BACKGROUND: Gout pain seriously affects the quality of patients' life. There is still no effective treatment. The inflammatory response is the main mechanism of gout. Here, we found that ozone can reduce the inflammatory reaction in the joints of gouty mice and relieve gout pain, and we further explore its protective mechanism. METHODS: MSU was used to establish the gouty mice model. Nociception was assessed by Von Frey hairs. Cell signaling assays were performed by western blotting and immunohistochemistry. The mouse leukemia cells of monocyte macrophage line RAW264.7 were cultured to investigate the effects of ozone administration on macrophage. RESULTS: Ozone reduced inflammation, relieved gout pain and improved the paw mean intensity and duty cycle of the gouty mice. Ozone increased the phosphorylation of AMP-activated protein kinase (AMPK), induced suppressor of cytokine signaling 3 (SOCS3) expression and inhibited metallopeptidase 9 (MMP9) expression. In vivo, ozone activated AMPK to induce Gas6 release, and upregulated MerTK/SOCS3 signaling pathway to reduce inflammation in mouse macrophage line RAW264.7. Inhibitors of AMPK and MerTK, respectively abolished the analgesic and anti-inflammatory effects of ozone in vivo and in vitro. Gas6 knockout cancelled the protectively effects of ozone on gout pain and the paw mean intensity and duty cycle of gouty mice. Additionally, the level of Gas6 and protein S in plasma of patients with hyperuricemia was significantly higher than that of healthy contrast group. CONCLUSION: Ozone reduces inflammation and alleviates gout pain by activating AMPK to up-regulate Gas6/MerTK/SOCS3 signaling pathway.

Evaluation and Treatment of Knee Pain: A Review.

Importance: Approximately 5% of all primary care visits in adults are related to knee pain. Osteoarthritis (OA), patellofemoral pain, and meniscal tears are among the most common causes of knee pain. Observations: Knee OA, affecting an estimated 654 million people worldwide, is the most likely diagnosis of knee pain in patients aged 45 years or older who present with activity-related knee joint pain with no or less than 30 minutes of morning stiffness (95% sensitivity; 69% specificity). Patellofemoral pain typically affects people younger than 40 years who are physically active and has a lifetime prevalence of approximately 25%. The presence of anterior knee pain during a squat is approximately 91% sensitive and 50% specific for patellofemoral pain. Meniscal tears affect an estimated 12% of the adult population and can occur following acute trauma (eg, twisting injury) in people younger than 40 years. Alternatively, a meniscal tear may be a degenerative condition present in patients with knee OA who are aged 40 years or older. The McMurray test, consisting of concurrent knee rotation (internal or external to test lateral or medial meniscus, respectively) and extension (61% sensitivity; 84% specificity), and joint line tenderness (83% sensitivity; 83% specificity) assist diagnosis of meniscal tears. Radiographic imaging of all patients with possible knee OA is not recommended. First-line management of OA comprises exercise therapy, weight loss (if overweight), education, and self-management programs to empower patients to better manage their condition. Surgical referral for knee joint replacement can be considered for patients with end-stage OA (ie, no or minimal joint space with inability to cope with pain) after using all appropriate conservative options. For patellofemoral pain, hip and knee strengthening exercises in combination with foot orthoses or patellar taping are recommended, with no indication for surgery. Conservative management (exercise therapy for 4-6 weeks) is also appropriate for most meniscal tears. For severe traumatic (eg, bucket-handle) tears, consisting of displaced meniscal tissue, surgery is likely required. For degenerative meniscal tears, exercise therapy is first-line treatment; surgery is not indicated even in the presence of mechanical symptoms (eg, locking, catching). Conclusions and Relevance: Knee OA, patellofemoral pain, and meniscal tears are common causes of knee pain, can be diagnosed clinically, and can be associated with significant disability. First-line treatment for each condition consists of conservative management, with a focus on exercise, education, and self-management.

Hip Pain and Physical Therapy Nonarthritic Hip Pain: What Is It? What Should I Do About It? How Do I Get Back to My Regular Activities?

Hip pain can have many causes, both arthritic and non-arthritic. Experts in managing hip pain developed a guideline to help rehabilitation clinicians help you understand more about hip pain. Here we explain what physical therapy might offer you if you have hip pain and arthritis has been ruled out. You will find out about some of the leg strength and balance tests your physical therapist might ask you to do, and exercises to help alleviate your hip pain and improve your strength, movement and balance.J Orthop Sports Phys Ther 2023;53(10):643-644. doi:10.2519/jospt.2023.0506.

Effects of Hip Pain Diagnostic Labels and Their Explanations on Beliefs About Hip Pain and How to Manage It: An Online Randomized Controlled Trial.

OBJECTIVES: To compare the effects of diagnostic labels and their explanations on people's beliefs about managing hip pain. DESIGN: Online randomized controlled trial involving 626 participants. METHODS: Participants aged ≥45 years with and without hip pain considered a hypothetical scenario (initial doctor consultation for hip pain). They were randomized to receive a diagnostic label and explanation of (1) hip osteoarthritis, (2) persistent hip pain, or (3) hip degeneration. Primary outcomes were the beliefs (1) exercise would damage the hip and (2) surgery is necessary at some stage (scales, 0 = definitely would not/unnecessary, 10 = definitely would/necessary). Secondary outcomes included beliefs about other treatments and care providers. RESULTS: Compared to hip degeneration, participants who were allocated to hip osteoarthritis and persistent hip pain believed exercise was less damaging (mean difference -1.3 [95% CI: -1.9, -0.7] and -1.8 [-2.3, -1.2], respectively) and surgery less necessary (-1.5 [-2.1, -1.0] and -2.2 [-2.7, -1.6], respectively). Compared to hip osteoarthritis, participants who were allocated to persistent hip pain believed surgery was less necessary (-0.7 [-1.2, -0.1]), but not that exercise was less damaging (-0.5 [-1.1, 0.1]). Compared to hip degeneration, participants who were allocated to hip osteoarthritis and persistent hip pain were less concerned about their hip and believed exercise and care from an exercise and sports physician, rheumatologist, or physiotherapist would be more helpful, and care from an orthopaedic surgeon less helpful. CONCLUSIONS: People who were allocated a diagnostic label and explanation of hip osteoarthritis or persistent hip pain believed exercise was less damaging and surgery less necessary for a hip problem than hip degeneration.

Transcatheter arterial embolisation for the relief of shoulder and elbow chronic joint pain refractory to conventional treatment: Systematic review.

Angiogenesis and accompanying nerve fibres might cause unsettling joint pain. Studies have suggested that transcatheter arterial embolisation (TAE) of these abnormal neovessels could relieve pain and symptoms in patients with upper limb joint pain refractory to conventional treatment. This study aims to investigate the efficacy and safety of TAE in treating chronic pain of shoulder and elbow joints that have been resistant to other treatments. Using six databases, a systematic review was performed following Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. The primary outcome involved changes in the visual analogue scale (VAS) after TAE; while secondary outcomes involved comparing other parameters where relevant. Average VAS decreased from baseline, then at 1 day, 1 week, 1 month, 3 months, 4 months, 6 months, 1 year, 2 years and 44 months (7.5 at baseline vs. 4.7, 4.3, 3.4, 2.1, 2.5, 1.2, 0.7, 1.1 and 0.1, respectively). Average Quick-DASH scores decreased from baseline, then at 1, 3 and 6 months (61.3 at baseline vs. 30.6, 19.3 and 6.9, respectively). Minor adverse events were reported in 27/143 (18.9%) patients, where they resolved spontaneously or with oral analgesia. TAE is a possible treatment option for refractory shoulder and elbow joint pain; however, randomised controlled trials are still required.

Hip Pain in an Athlete.

ABSTRACT: Hip pain is a common complaint in sports, and narrowing the differential diagnosis can be difficult. Many etiologies are secondary to overuse and respond well to nonsurgical treatment. The increased use of point-of-care ultrasound has helped provide timely and accurate diagnoses and some guided treatments. The hip is in close proximity to the abdomen and pelvis, and clinicians should be familiar with nonmusculoskeletal pain generators. This article is a comprehensive review of hip pain etiologies in athletes.

The preliminary development and clinical verification of the positive index score scale of "Heart Arthralgia Syndrome".

BACKGROUND: In recent years, the age of onset for coronary heart disease (CHD) has become one of the leading causes of death worldwide. The medical treatments occasionally cause side effects; therefore, there is still an urgent need to develop new therapeutic modalities for CHD in clinical practice. "Heart Arthralgia Syndrome (HAS)" is a general term for CHD with arthralgia symptoms proposed by our team based on clinical experience. At present, there is little in-depth research on the treatment of HAS by TCM. Pick Complex Therapy (PCT) is an innovative and developed theory of collateral acupuncture therapy for HAS. METHODS: We collected data from 276 patients who met the criteria for (coronary heart disease with numbness of neck, shoulder, waist, and leg). We selected 24 diagnostic criteria for HAS by means of multiple methods, including Cronbach's α coefficient, retest reliability, subjective evaluation, discrete trend, Pearson's rank correlation coefficient and factor analysis method. We thereafter evaluated the reliability, validity and responsiveness of the scale. In the clinical validation phase, we verified whether the preliminary developed positive index (PI) scale can guide clinical practice. Forty (40) patients with HAS were selected in the study. SPSS23.0 statistical software was used for statistical processing and analysis. RESULTS: Assessment results of the initial PI scale for HAS: the average time to complete the scale was 7.47 ± 3.59 minutes. Cronbach's α coefficient for the initial table was 0.711, the retest reliability was 0.897, the Kaiser-Meyer-Olkin test result was 0.844, and the Bartlett test result was 2502.300. Following maximum variance rotation analysis, the cumulative variance contribution rate was determined to be 66.605%. In the clinical validation phase of the PI scale, we tested 40 patients before and after the PCT treatments. After 3 measurements, the correlation between the PI scale for HAS and the angina pectoris grading scoring method table decreased gradually. The last 2 measurement results of study indicated that there was a significant correlation between the PI scale and thrombin time, while physical and chemical examination showed no significant changes. CONCLUSION: The PI scale for HAS can be widely used in the clinic as a preliminary evaluation tool for guiding PCT.

Regular walking exercise prior to knee osteoarthritis reduces joint pain in an animal model.

We investigated the effect of regular walking exercise prior to knee osteoarthritis (OA) on pain and synovitis in a rat monoiodoacetic acid (MIA)-induced knee OA model. Seventy-one male Wistar rats were divided into three groups: (i) Sedentary + OA, (ii) Exercise + OA, and (iii) Sedentary + Sham groups. The Exercise + OA group underwent a regular treadmill walking exercise at 10 m/min (60 min/day, 5 days/week) for 6 weeks, followed by a 2-mg MIA injection in the right knee. The right knee joint was removed from rats in this group at the end of the 6-week exercise period and at 1 and 6 weeks after the MIA injection. After the 6 weeks of treadmill exercise but before MIA injection, there were no significant differences among the three groups in the pressure pain threshold, whereas at 1 week post-injection, the Exercise + OA group's pressure pain threshold was significantly higher than that in the Sedentary + OA group, and this difference persisted until the end of the experimental period. The histological changes in articular cartilage and subchondral bone revealed by toluidine blue staining showed no difference between the Sedentary + OA and EX + OA groups. The expression levels of interleukin (IL)-4 and IL-10 mRNA in the infrapatellar fat pad and synovium were significantly increased by the treadmill exercise. Significant reductions in the number of CD68-, CD11c-positive cells and IL-1ß mRNA expression and an increase in the number of CD206-positive cells were observed at 1 week after the MIA injection in the Exercise + OA group compared to the Sedentary + OA group. These results suggest that regular walking exercise prior to the development of OA could alleviate joint pain through increases in the expressions of anti-inflammatory cytokines in the rat infrapatellar fat pad and synovium.

Prediction of knee joint pain in Tai Chi practitioners: a cross-sectional machine learning approach.

OBJECTIVE: To build a supervised machine learning-based classifier, which can accurately predict whether Tai Chi practitioners may experience knee pain after years of exercise. DESIGN: A prospective approach was used. Data were collected using face-to-face through a self-designed questionnaire. SETTING: Single centre in Shanghai, China. PARTICIPANTS: A total of 1750 Tai Chi practitioners with a course of Tai Chi exercise over 5 years were randomly selected. MEASURES: All participants were measured by a questionnaire survey including personal information, Tai Chi exercise pattern and Irrgang Knee Outcome Survey Activities of Daily Living Scale. The validity of the questionnaire was analysed by logical analysis and test, and the reliability of this questionnaire was mainly tested by a re-test method. Dataset 1 was established by whether the participant had knee pain, and dataset 2 by whether the participant's knee pain affected daily living function. Then both datasets were randomly assigned to a training and validating dataset and a test dataset in a ratio of 7:3. Six machine learning algorithms were selected and trained by our dataset. The area under the receiver operating characteristic curve was used to evaluate the performance of the trained models, which determined the best prediction model. RESULTS: A total of 1703 practitioners completed the questionnaire and 47 were eliminated for lack of information. The total reliability of the scale is 0.94 and the KMO (Kaiser-Meyer-Olkin measure of sampling adequacy) value of the scale validity was 0.949 (>0.7). The CatBoost algorithm-based machine-learning model achieved the best predictive performance in distinguishing practitioners with different degrees of knee pain after Tai Chi practice. 'Having knee pain before Tai Chi practice', 'knee joint warm-up' and 'duration of each exercise' are the top three factors associated with pain after Tai Chi exercise in the model. 'Having knee pain before Tai Chi practice', 'Having Instructor' and 'Duration of each exercise' were most relevant to whether pain interfered with daily life in the model. CONCLUSION: CatBoost-based machine learning classifier accurately predicts knee pain symptoms after practicing Tai Chi. This study provides an essential reference for practicing Tai Chi scientifically to avoid knee pain.

Effect of instrument-assisted soft tissue mobilization combined with blood flow restriction training on function, pain and strength of patients with patellofemoral joint pain.

BACKGROUND: Patellofemoral pain syndrome is a prevalent sports injury that affects athletes both in their daily lives and during training. This condition causes pain in the area where the kneecap and thigh bone meet, and it can be quite debilitating. Whether an athlete is simply going about their day or pushing themselves to the limit during a workout, patellofemoral pain can be a significant hindrance. PURPOSE: The purpose of this study is to investigate the impact of combining Instrument-Assisted Soft Tissue Mobilization (IASTM) treatment with blood flow restriction training on individuals with patellofemoral pain. Specifically, the study will assess improvements in pain levels, functional ability, strength, and joint mobility resulting from this treatment approach. METHODS: Twenty-six patients diagnosed with patellofemoral pain were selected as observation subjects and randomly divided into two groups: the IASTM combined with blood flow restriction training treatment group (n = 13) and the IASTM treatment group alone (n = 13). The treatment period was 4 weeks. In this study, we conducted a comparison and analysis of the knee's visual analogue pain scale (VAS), Lysholm score, and a modified version of the Thomas test (MTT) at three different time points.In this subject paper, we compared and analyzed the VAS score of the knee, Lysholm score of the knee, and MTT at three different time points-before treatment, immediately after the first treatment, and after four weeks of treatment. Additionally, we recorded data using a maximum isometric muscle strength testing system for the lower extremity extensors four weeks before and after treatment. RESULTS: In comparing the Lysholm scores within the groups, a significant difference was observed between the two groups following the initial treatment and after 4 weeks of treatment (p < 0.05). The scores increased, indicating a significant improvement in function. The VAS scores significantly differed after the first treatment and 4 weeks of treatment compared to before treatment (p < 0.05), indicating a significant improvement in pain. Additionally, after 4 weeks of treatment, the strength of the extensor muscle in the lower extremity significantly improved (p < 0.001). However, there was no significant difference in the strength test between the groups (p > 0.05). The MTT test revealed significant changes in the three joint angles before and after treatment (p > 0.05), suggesting an improvement in joint mobility. Overall, these results demonstrate the effectiveness of the treatment in improving pain and muscle strength in the lower extremity. CONCLUSION: The combination of IASTM treatment and blood flow restriction has been shown to significantly reduce pain and improve periprosthetic soft tissue flexibility. Additionally, IASTM treatment alone was found to be more effective in improving knee pain and muscle flexibility, ultimately leading to increased knee strength in a pain-free state. In terms of the overall treatment outcome, it was found that the combined treatment was significantly more effective than the adjuvant soft tissue release treatment alone.

Comparison of Joint Mobilization and Movement Pattern Training for Patients With Hip-Related Groin Pain: A Pilot Randomized Clinical Trial.

OBJECTIVE: The objective of this study was to assess the feasibility of completing a randomized clinical trial (RCT) and examine the preliminary effects of 2 interventions for hip-related groin pain (HRGP). METHODS: In this pilot RCT, patients with HRGP, who were 18 to 40 years old, were randomized (1:1 ratio) to a joint mobilization (JtMob) group or a movement pattern training (MoveTrain) group. Both treatments included 10 supervised sessions and a home exercise program. The goal of JtMob was to reduce pain and improve mobility through peripherally and centrally mediated pain mechanisms. The key element was physical therapist-provided JtMob. The goal of MoveTrain was to reduce hip joint stresses by optimizing the biomechanics of patient-specific tasks. The key element was task-specific instruction to correct abnormal movement patterns displayed during tasks. Primary outcomes were related to future trial feasibility. The primary effectiveness outcome was the Hip Disability and Osteoarthritis Outcome Score. Examiners were blinded to group; patients and treatment providers were not. Data collected at baseline and immediately after treatment were analyzed with analysis of covariance using a generalized linear model in which change was the dependent variable and baseline was the covariate. The study was modified due to the coronavirus disease 2019 (COVID-19) pandemic. RESULTS: The COVID-19 pandemic affected participation; 127 patients were screened, 33 were randomized (18 to the JtMob group and 15 to the MoveTrain group), and 29 (88%) provided posttreatment data. Treatment session adherence was 85%, and home exercise program component adherence ranged from 71 to 86%. Both groups demonstrated significant mean within-group improvements of ≥5 points on Hip Disability and Osteoarthritis Outcome Score scales. There were no between-group differences in effectiveness outcomes. CONCLUSIONS: A large RCT to assess the effects of JtMob and MoveTrain for patients with HRGP may be feasible. Preliminary findings suggested that JtMob or MoveTrain may result in improvements in patient-reported pain and activity limitations. IMPACT: The COVID-19 pandemic interfered with participation, but a randomized controlled trial may be feasible. Modification may be needed if the trial is completed during future pandemics.
