Changes in pulmonary function following thoracic spine manipulation in a healthy inactive older adult population-a pilot study.

[Purpose] Pulmonary function pathology is primarily treated pharmacologically, with a range of medication side effects. Few studies have systematically examined non-pharmacologic approaches such as joint manipulation effects on pulmonary function. This study examined the immediate and short-term effects of thoracic manipulation on pulmonary function. [Participants and Methods] Twenty-one physically inactive otherwise healthy participants aged 50 years or older were randomly assigned to either receive three sessions of thoracic manipulation (n=10) or three sessions of "sham intercostal training" (n=11). Outcome measures included forced vital capacity, maximal voluntary ventilation and thoracic excursion during maximal inhalation and exhalation. [Results] There was a statistically significant difference in maximal voluntary ventilation in the manipulation group, when measured within a week of the third intervention session and immediate effects in thoracic excursion during exhalation in the sham group following a single intervention session. There were no significant changes in other measures. [Conclusion] Spinal manipulation had no immediate effect on pulmonary function, however, affected an improvement in maximal voluntary ventilation within 7 days following a third session. The sham intervention showed a change in thoracic excursion during exhalation after the first session. Future research is necessary to further explore the relationship between thoracic manipulation and pulmonary function.

Patient-Reported Outcome Measures for Adults and Adolescents With Patellofemoral Pain: A Systematic Review of Construct Validity, Reliability, Responsiveness, and Interpretability Using the COSMIN Methodology.

OBJECTIVE: We aimed to appraise the construct validity, reliability, responsiveness, and interpretability of patient-reported outcome measures (PROMs) used to assess function and pain in adults and adolescents with patellofemoral pain (PFP). DESIGN: Systematic review of measurement properties LITERATURE SEARCH: We searched the PubMed, CINAHL, Scopus, SPORTDiscus, and Cochrane Library databases from inception to January 6, 2022. STUDY SELECTION CRITERIA: We included studies that assessed the measurement properties of English-language PROMs for PFP and their cultural adaptations and translations. DATA SYNTHESIS: Using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) methodology, we determined overall ratings and quality of evidence for construct validity, internal consistency, reliability, measurement error, and responsiveness. We extracted data related to interpretability for clinical use. RESULTS: After screening 7066 titles, 61 studies for 33 PROMs were included. Only 2 PROMs had evidence of "sufficient" or "indeterminate" quality for all measurement properties. The Knee injury and Osteoarthritis Outcome Score patellofemoral subscale (KOOS-PF) had "low" to "high" quality evidence for a rating of "sufficient" for 4 measurement properties. The Lower Extremity Functional Scale (LEFS) had very low-quality evidence for a "sufficient" rating for 4 measurement properties. The KOOS-PF and LEFS were rated "indeterminate" for structural validity and internal consistency. The KOOS-PF had the best interpretability with reported minimal important change and 0% ceiling and floor effects. No studies examined cross-cultural validity. CONCLUSION: The KOOS-PF and LEFS had the strongest measurement properties among PROMs used for PFP. More research is needed, particularly regarding structural validity and interpretability of PROMs. J Orthop Sports Phys Ther 2023;53(8):1-20. Epub: 20 June 2023. doi:10.2519/jospt.2023.11730.

Physical therapist perceptions and use of clinical pain mechanism assessment in the musculoskeletal setting: a survey analysis.

BACKGROUND: A mechanism-based approach to the evaluation and management of pain has been suggested across disciplines in contemporary research. However, the translation of pain mechanism assessment strategies in research to clinical practice is unclear. This study sought to explore perceptions and use of clinical pain mechanism assessment by physical therapists managing musculoskeletal pain. METHODS: This was an electronic cross-sectional survey. After initial development, refinement, and piloting for comprehensiveness, comprehensibility and relevance, the survey was disseminated to members of the Academy of Orthopaedic Physical Therapy via email listserv. Data was maintained anonymously using the online database REDCap. Descriptive statistics and Spearman's correlations for non-parametric data were analyzed for frequencies and associations across variables. RESULTS: In total, 148 respondents completed all aspects of the survey. Respondent age ranged from 26 to 73 years, with a mean (SD) of 43.9 (12.0). Most respondents (70.8%) reported performing clinical pain mechanism assessments at least 'sometimes'. A majority (80.4%) believed clinical pain mechanism assessments are useful in guiding management strategies while 79.8% reported specifically choosing interventions to alter aberrant pain mechanisms. The most commonly used pain severity, physical examination testing and questionnaires were the numeric pain rating scale, pressure pain thresholds and pain diagrams, respectively. However, the vast majority of instruments to clinically assess pain mechanisms were performed by a small proportion of respondents (< 30%). There were no significant correlations between age, years of experience, highest earned degree, completion of advanced training or specialist certification and testing frequency. CONCLUSION: The evaluation of pain mechanisms involved in the pain experience is becoming common in research. The clinical application of pain mechanism assessment is unclear. Based on the results of this survey, physical therapists in the orthopedic setting believe pain mechanism assessment is useful, but data suggests it is infrequently performed. Additional research to uncover clinician motivation related to pain mechanism assessment is warranted.

Patient-Reported Outcome Measures for Adults and Adolescents with Patellofemoral Pain: A Systematic Review of Content Validity and Feasibility Using the COSMIN Methodology.

OBJECTIVE: To assess the content validity and feasibility of patient-reported outcome measures (PROMs) used to assess pain and function in adults and adolescents with patellofemoral pain (PFP). DESIGN: Systematic review. LITERATURE SEARCH: We searched the databases PubMed, CINAHL, Scopus, SPORTDiscus, and the Cochrane Library from inception to January 6, 2022. STUDY SELECTION CRITERIA: We included studies that described the development or evaluation of the content validity of English-language PROMs for PFP, as well as their translations and cultural adaptations to different languages. DATA SYNTHESIS: Using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) methodology, we determined overall ratings and quality of evidence for the relevance, comprehensiveness, and comprehensibility of PROMs. We extracted data related to feasibility for clinical use (eg, administration time and scoring ease). RESULTS: Forty-three studies for 33 PROMs were included. The overall quality of most studies was "inadequate" due to failure to engage stakeholders and/or ensure adherence to rigorous qualitative research procedures. Of all PROMs evaluated, the Knee injury and Osteoarthritis Outcome Score-Patellofemoral subscale (KOOS-PF), was the only PROM with sufficient content validity components. Quality of evidence for content validity of the KOOS-PF was low. Most PROMs were rated feasible for clinical and research purposes. CONCLUSION: Most PROMs used to measure pain and function in patients with PFP have inadequate content validity. The KOOS-PF had the highest overall content validity. We recommend the KOOS-PF for evaluating pain and function (in research and clinical practice) in adults and adolescents with PFP. J Orthop Sports Phys Ther 2023;53(1):23-39. Epub: 18 October 2022. doi:10.2519/jospt.2022.11317.

A Closer Look at Localized and Distant Pressure Pain Hypersensitivity in People With Lower Extremity Overuse Soft-Tissue Painful Conditions: A Systematic Review and Meta-Analysis.

OBJECTIVE: The nociceptive pain processing of soft-tissue overuse conditions is under debate because no consensus currently exists. The purpose of this meta-analysis was to compare pressure pain thresholds (PPTs) in symptomatic and distant pain-free areas in 2 groups: participants with symptomatic lower extremity overuse soft-tissue conditions and controls who were pain free. METHODS: Five databases were searched from inception to December 1, 2021, for case-control studies comparing PPTs between individuals presenting with symptomatic lower extremity tendinopathy/overuse injury and controls who were pain free. Data extraction included population, diagnosis, sample size, outcome, type of algometer, and results. The methodological quality (Newcastle-Ottawa Quality Assessment Scale) and evidence level (Grading of Recommendations Assessment, Development, and Evaluation) were assessed. Meta-analyses of symptomatic, segmental related, and distant pain-free areas were compared. RESULTS: After screening 730 titles and abstracts, a total of 19 studies evaluating lower extremity overuse conditions (Achilles or patellar tendinopathy, greater trochanteric pain syndrome, plantar fasciitis, and iliotibial band syndrome) were included. The methodological quality ranged from fair (32%) to good (68%). Participants with lower extremity overuse injury had lower PPTs in both the painful and nonpainful areas, mirrored test-site, compared with controls (affected side: mean difference [MD] = -262.92 kPa, 95% CI = 323.78 to -202.05 kPa; nonaffected side: MD = -216.47 kPa, 95% CI = -304.99 to -127.95 kPa). Furthermore, people with plantar fasciitis showed reduced PPTs in the affected and nonaffected sides at segmental-related (MD = -176.39 kPa, 95% CI = -306.11 to -46.68 kPa) and distant pain-free (MD = -97.27 kPa, 95% CI = 133.21 to -61.33 kPa) areas compared with controls. CONCLUSION: Low- to moderate-quality evidence suggests a reduction of PPTs at the symptomatic area and a contralateral/mirror side in lower extremity tendinopathies and overuse conditions compared with pain-free controls, particularly in plantar fasciitis and greater trochanteric pain syndrome. Participants with plantar fasciitis showed a reduction of PPTs on the affected and non-affected sides at a segmental-related area (very low-quality evidence) and at a remote asymptomatic area (moderate-quality evidence). IMPACT: Some overuse peripheral pain conditions may be more associated with pressure pain sensitivity than others. Accordingly, examination and identification of conditions more peripherally, centrally, or mixed mediated could potentially lead to more specific and different treatment strategies.

Manual therapy should not be on the sideline in the game of treating tendinopathy.

Tendinopathy is a common but difficult condition to manage in the orthopedic and sports settings. Despite strong evidence supporting exercise and load-management, a substantial proportion of individuals with the condition do not achieve a satisfactory long-term outcome. Tendinopathy can be associated with a number of impairments, including mobility deficits, muscle performance impairments, pain, and possible altered central pain processing - all of which are indications for manual therapy. Manual therapy has not been well described in the management of tendinopathy, even though its indications match the impairments associated with the condition. In this clinical perspective, the role of manual therapy in the management of tendinopathy is explored, with the intention of expanding possible treatment strategies for this challenging condition.

The utilization and effects of filiform dry needling in the management of tendinopathy: a systematic review.

BACKGROUND: Tendinopathy is frequently associated with pain, soft tissue impairments and muscle performance limitations. Dry needling (DN) incorporates a fine filiform needle to penetrate the skin and underlying soft tissue in an effort to decrease pain and improve function. While injectable interventions and gauged-needle tendon fenestration for tendinopathy has been reviewed, DN for tendinopathy has yet to be synthesized. OBJECTIVE: To systematically review the utilization and effects of DN for tendinopathy. METHODS: Six electronic databases (PubMed, CINAHL, Scopus, SportDiscus, PEDro and the Cochrane Library) were searched from inception through August 15, 2020, using appropriate keywords and relevant synonyms. RESULTS: After screening 462 articles, 10 studies met inclusion criteria. Study designs included case reports, case series, and randomized clinical trials. DN was used in isolation in 3/10 studies and as part of a multimodal approach in 7/10 studies. DN was associated with improved pain, function, muscle performance and perceived improvement in each study evaluating the relevant outcome. Conflicting results were found in comparative studies evaluating DN. CONCLUSIONS: DN may be a useful adjunctive treatment in the conservative management of tendinopathy, although its discrete effect is unclear. Very Low-quality evidence and methodological limitations suggest further investigation is warranted.

Altered Central Pain Processing in Patients With Chronic Plantar Heel Pain: A Critically Appraised Topic.

Clinical Scenario: Plantar heel pain is a common condition frequently associated with persistent symptoms and functional limitations affecting both the athletic and nonathletic populations. Common interventions target impairments at the foot and ankle and local drivers of symptoms. If symptoms are predominantly perpetuated by alterations in central pain processing, addressing peripheral impairments alone may not be sufficient. Clinical Question: Do individuals with chronic plantar heel pain demonstrate signs potentially associated with altered central pain processing? Summary of Key Findings: After searching 6 electronic databases (PubMed, CINAHL, Scopus, SportDiscus, Cochrane, and PEDro) and filtering titles based on predetermined inclusion and exclusion criteria, 4 case-control studies were included. All studies scored highly on the Newcastle-Ottawa Scale for quality assessment. Using pressure pain thresholds, each study found decreased pressure pain hypersensitivity locally and at a remote site compared to control groups, suggesting the presence, to some extent, of altered nociceptive pain processing. Clinical Bottom Line: In the studies reviewed, reported results suggest a possible presence of centrally mediated symptoms in persons with plantar heel pain. However, despite findings from these studies, limitations in appropriate matching based on body mass index and measures used suggest additional investigation is warranted. Strength of Recommendation: According to the Oxford Centre for Evidence-Based Medicine, there is evidence level C to suggest chronic plantar heel pain is associated with alterations in central pain processing.

Eccentric exercise in the prevention of patellofemoral pain in high-volume runners: A rationale for integration.

Patellofemoral pain (PFP) is a common overuse condition seen in high-volume runners, such as military recruits. Exercise is commonly prescribed, with benefit, for the rehabilitation of individuals with PFP. However, a substantial number of individuals with the condition do not achieve an optimal outcome, suggesting the condition can be difficult and complex. Given the challenging nature of the condition, and the risk of developing PFP in high-volume runners, it seems logical to investigate options for injury prevention. Eccentric exercise has been useful in the prevention of some pathologies so its utility in preventing PFP should be explored. Current evidence regarding prevention programs for PFP are limited. Preventative exercise programs for PFP have not been well described or reported, and questions remain regarding their effectiveness. Based on available evidence or lack thereof, and known physiological and clinical effects of eccentric exercise, suggestions for integration of eccentric exercise into PFP prevention programs are offered. Eccentric exercise may be useful for PFP prevention from a theoretical framework however additional longitudinal cohort studies would be useful in determining its utility.

Hand-held dynamometer to measure pressure pain thresholds: A double-blinded reliability and validity study.

BACKGROUND: Pain is the most common complaint reported in the musculoskeletal setting. Quantitative sensory testing (QST) assists with pain mechanism identification, although QST is typically performed in research settings. It is possible that clinical utilization of QST may improve if clinically accessible tools can be reliably and validly used. OBJECTIVE: To determine if a hand-held dynamometer (HHD) can be a valid and reliable assessment of pressure pain threshold (PPT). DESIGN: Double-blinded validation study. METHODS: Eighteen healthy subjects (25.6 ± 3.4 years old) participated in this study. Two testers independently assessed PPT using a HHD and a digital algometer. Assessments followed previously described pressure algometry protocols. Testers and subjects were each blinded to data during assessments. RESULTS: Intra- and inter-rater reliability were excellent for the foot and face for both devices (ICC's > 0.9). Bland-Altman plots and intraclass correlation coefficients revealed good-excellent agreement with minimal proportional bias when normalizing device force at pain threshold to the circumference of the device applicator (ICC 95%CI: 0.56-0.95). Only poor-good agreement (ICC 95% CI: 0.30-0.76) and significant proportional bias was observed when normalizing to area (pressure). CONCLUSIONS: Based on the results of this study, when force is normalized by circumference of the applicator, a HHD was found to be a valid and reliable tool for measuring PPT. Clinicians may use HHD to detect relevant pain mechanisms at fault in their evaluation and treatment of pain. Additional research in various pathologic populations is warranted.

FUNCTIONAL JOINT MOBILIZATIONS FOR PATELLOFEMORAL PAIN SYNDROME: A CLINICAL SUGGESTION.

Patellofemoral pain syndrome (PFPS) is often effectively managed with appropriate exercise prescription, yet in many cases PFPS related symptoms can become persistent and result in reduced daily, functional and sport-related activity levels. Patellofemoral mobilizations may be incorporated to minimize the impact of mobility deficits, and are frequently performed in the patellofemoral joint's open-packed position of knee extension. However, many individuals with PFPS have pain during weight-bearing activities requiring knee flexion such as stairs, squatting, or running. Therefore, it seems reasonable that utilizing joint mobilizations in more symptomatic functional positions may enhance treatment plans. The purpose of this clinical suggestion is to present patellofemoral joint mobilization options in positions more closely replicating positions of symptom provocation, in an effort to offer clinicians different intervention strategies for the challenging condition of PFPS. LEVEL OF EVIDENCE: 5.

The Utilization of Joint Mobilization As Part of a Comprehensive Program to Manage Carpal Tunnel Syndrome: A Systematic Review.

OBJECTIVE: The purpose of this review is to identify the role of joint mobilization for individuals with Carpal tunnel syndrome (CTS). METHODS: A systematic search of 5 electronic databases (PubMed, CINAHL, Scopus, Cochrane Central Register of Controlled Trials, and SPORTDiscus) was performed to identify eligible full-text randomized clinical trials related to the clinical question. Joint mobilization had to be included in one arm of the randomized clinical trials to be included. Two reviewers independently participated in each step of the screening process. A blinded third reviewer assisted in cases of discrepancy. The PEDro scale was used to assess quality. RESULTS: Ten articles were included after screening 2068 titles. In each article where joint mobilization was used, positive effects in pain, function, or additional outcomes were noted. In most cases, the intervention group integrating joint mobilization performed better than the comparison group not receiving joint techniques. CONCLUSION: In the articles reviewed, joint mobilization was associated with positive clinical effects for persons with CTS. No studies used joint mobilization in isolation; therefore, results must be interpreted cautiously. This review indicates that joint mobilization might be a useful adjunctive intervention in the management of CTS.

Multifaceted Exercise Prescription in the Management of an Overhead Athlete with Suspected Distal Biceps Tendinopathy: A Case Report.

BACKGROUND AND PURPOSE: Distal biceps brachii tendinopathy is an uncommon diagnosis. Various exercise prescriptions have demonstrated efficacy in the management of tendinopathy, although studies frequently focus on the effects of a specific type of muscular contraction (i.e., concentric, isometric, or eccentric). Currently, there is limited research guiding the conservative management of distal biceps tendinopathy, particularly with overhead athletes, and even less evidence reporting a multifaceted exercise prescription for individuals with tendinopathy. The purpose of this case report is to describe the integration of various modes of therapeutic exercise into a rehabilitation program for an overhead athlete with suspected distal biceps brachii tendinopathy. CASE DESCRIPTION: A 19-year-old male collegiate baseball pitcher presented to an outpatient physical therapy clinic via direct access for left antecubital pain, which began 6 weeks prior to the evaluation while pitching during try-outs. Following physical examination, distal biceps tendinopathy was the likely clinical diagnosis. Interventions focused on early eccentric exercise eventually progressing to concentric and plyometric activity for return to sport. OUTCOMES: The patient was seen five times over the course of 4 weeks. He had significant improvements of pain, patient-reported functional outcomes, global rating of change, strength, tenderness, and provocation testing. The patient was able to return to an off-season pitching program. DISCUSSION: An impairment-based and task-specific exercise prescription was effective for this patient with distal biceps tendinopathy. Understanding the biomechanical demands of an individual's functional limitation, in this case baseball pitching, may assist the decision-making process and optimize outcomes. Additional research into the most effective exercise prescriptions for individuals with uncommon tendinopathies is warranted.

Potential Nervous System Sensitization in Patients With Persistent Lower Extremity Tendinopathies: 3 Case Reports.

BACKGROUND: Tendinopathy is a condition often associated with pain and functional and sport performance limitations. While targeted exercise prescriptions are often effective, many patients with tendinopathy develop persistent symptoms. Emerging evidence suggests a possible link between nervous system sensitization and tendinopathy. If so, identifying and treating specific pain mechanisms may improve outcomes. CASE DESCRIPTION: Three patients were seen in physical therapy for complaints of ongoing chronic tendon pain and self-reported disability, despite being treated previously and receiving evidence-informed care. Upon examination, each patient demonstrated signs consistent with possible dysfunction of central pain mechanisms. Joint mobilization, pain neuroscience education, and aerobic exercise were primary interventions in each case to decrease pain and improve function. OUTCOMES: The 3 patients were treated for 5 sessions over the course of 8 weeks. Clinically significant improvement was noted in measures of pain, self-reported function, and pressure pain thresholds. At discharge, all patients were able to run without symptoms, and improvement was maintained at 1-year follow-up. DISCUSSION: Tendinopathy, while often described as local pain and dysfunction, may be associated with dysfunction of the nervous system. Identifying and treating pain mechanisms in addition to relevant impairments may be an appropriate intervention approach for individuals with tendinopathy. LEVEL OF EVIDENCE: Therapy, level 4. J Orthop Sports Phys Ther 2019;49(4):272-279. Epub 13 Feb 2019. doi:10.2519/jospt.2019.8600.

Eccentric Exercise for Achilles Tendinopathy: A Narrative Review and Clinical Decision-Making Considerations.

BACKGROUND: Achilles tendinopathy is a common health condition encountered in the orthopedic and sports medicine settings. Eccentric exercise is a common intervention in the management of pain and limited function for this patient population, although contemporary evidence suggests additional exercise methods may be effective as well. STUDY DESIGN: Narrative review: Methods: A literature review was performed using the electronic databases Pubmed and PEDRO for articles through February 2019. Randomized clinical trials integrating eccentric exercise, with or without co-interventions, were evaluated. Outcomes related to pain and/or function were considered. A patient case is provided to highlight decision making processes related to clinical prescription of eccentrics for Achilles tendinopathy. RESULTS: After screening titles and abstracts, seven studies were included for full review. Two articles compared eccentric exercise to a control group, four compared eccentrics to the use of modalities, while one used eccentric exercise as part of a multimodal intervention. In each case, eccentric exercise was effective in reducing pain and improving function. In comparison to other forms of exercise or additional interventions, eccentric exercise was frequently not more effective than other options. DISCUSSION: Eccentric exercise has been associated with clinical benefit in improving pain and function for patients with Achilles tendinopathy. Despite the available evidence reporting effectiveness of eccentrics, other options may be equally useful. Appropriate load modification and exercise prescription for patients with Achilles tendinopathy requires systematic clinical reasoning and incorporation of patient values to optimize outcomes.

The effects of joint mobilization on individuals with patellofemoral pain: a systematic review.

OBJECTIVE: To investigate and synthesize the effects of joint mobilization on individuals with patellofemoral pain syndrome. DATA SOURCES: Five electronic databases (CINAHL, the Cochrane Central Register of Controlled Trials, PubMed, Scopus, and SPORTDiscus) were used. REVIEW METHODS: Each database was searched from inception to 1 November 2017. Randomized controlled trials investigating a manual therapy intervention, with or without co-interventions, for persons with patellofemoral pain were included. Two reviewers independently screened the retrieved literature and appraised the quality of the selected studies using the PEDro rating scale. A third reviewer was used in cases of discrepancy to create a consensus. RESULTS: A total of 361 articles were identified in the search. Twelve randomized trials with a total of 499 participants were selected for full review. Within-group improvements in pain and function were noted for the manual therapy groups. Between-group improvements for short-term outcomes (three months or less) were greatest when joint mobilization was directed to the knee complex and used as part of a comprehensive approach. CONCLUSION: In the articles reviewed, joint mobilization appears to be most effective in improving pain and function when coupled with other interventions, although its discrete effect is unclear due to the reviewed studies' design and reporting.

The symptomatic and functional effects of manual physical therapy on plantar heel pain: a systematic review.

OBJECTIVES: Plantar heel pain is common and can be severely disabling. Unfortunately, a gap in the literature exists regarding the optimal intervention for this painful condition. Consequently, a systematic review of the current literature regarding manual therapy for the treatment of plantar heel pain was performed. METHODS: A computer-assisted literature search for randomized controlled trials in MEDLINE, EMBASE, Cochrane, CINAHL, and Rehabilitation & Sports Medicine Source, was concluded on 7 January 2014. After identification of titles, three independent reviewers selected abstracts and then full-text articles for review. RESULTS: Eight articles were selected for the final review and underwent PEDro scale assessment for quality. Heterogeneity of the articles did not allow for quantitative analysis. Only two studies scored ≥7/10 on the PEDro scale and included joint, soft tissue, and neural mobilization techniques. These two studies showed statistically greater symptomatic and functional outcomes in the manual therapy group. DISCUSSION: This review suggests that manual therapy is effective in the treatment of plantar heel pain; however, further research is needed to validate these findings given the preponderance of low quality studies.

Manual therapy and eccentric exercise in the management of Achilles tendinopathy.

Chronic Achilles tendinopathy (AT) is an overuse condition seen among runners. Eccentric exercise can decrease pain and improve function for those with chronic degenerative tendon changes; however, some individuals have continued pain requiring additional intervention. While joint mobilization and manipulation has not been studied in the management in Achilles tendinopathy, other chronic tendon dysfunction, such as lateral epicondylalgia, has responded well to manual therapy (MT). Three runners were seen in physical therapy (PT) for chronic AT. They were prescribed eccentric loading exercises and calf stretching. Joint mobilization and manipulation was implemented to improve foot and ankle mobility, decrease pain, and improve function. Immediate within-session changes in pain, heel raise repetitions, and pressure pain thresholds (PPT) were noted following joint-directed MT in each patient. Each patient improved in self-reported function on the Achilles tendon specific Victorian Institute for Sport Assessment questionnaire (VISA-A), pain levels, PPT, joint mobility, ankle motion, and single-leg heel raises at discharge and 9-month follow-up. The addition of MT directed at local and remote sites may enhance the rehabilitation of patients with AT. Further research is necessary to determine the efficacy of adding joint mobilization to standard care for AT. LEVEL OF EVIDENCE: Case series. Therapy, Level 4.

Atypical Clinical Presentation of Rapidly Progressing Femoral Head Avascular Necrosis.

A 51-year-old man presented to an urgent care facility 2 weeks after onset of left lateral hip and buttock pain. Radiographs were noncontributory. An orthopaedist referred him to physical therapy, but due to the worsening clinical presentation, he was referred back to the orthopaedist for additional evaluation. Magnetic resonance imaging was ordered and demonstrated abnormal femoral head and acetabular contour, extensive bone marrow edema, and a complex joint effusion. He was diagnosed with femoral head avascular necrosis. J Orthop Sports Phys Ther 2017;47(3):217. doi:10.2519/jospt.2017.6483.

JOINT MOBILIZATION IN THE MANAGEMENT OF PERSISTENT INSERTIONAL ACHILLES TENDINOPATHY: A CASE REPORT.

BACKGROUND & PURPOSE: Insertional Achilles tendinopathy (IAT) can be a challenging condition to manage conservatively. Eccentric exercise is commonly used in the management of chronic tendinopathy; however, it may not be as helpful for insertional tendon problems as compared to mid-portion dysfunction. While current evidence describing the physical therapy management of IAT is developing, gaps still exist in descriptions of best practice. The purpose of this case report is to describe the management of a patient with persistent IAT utilizing impairment-based joint mobilization, self-mobilization, and exercise. CASE DESCRIPTION: A 51-year-old male was seen in physical therapy for complaints of posterior heel pain and reduced running capacity. He was seen by multiple physical therapists previously, but reported continued impairment, and functional restriction. Joint-based non-thrust mobilization and self-mobilization exercise were performed to enhance his ability to run and reduce symptoms. OUTCOMES: The subject was seen for four visits over the course of two months. He made clinically significant improvements on the Foot and Ankle Activity Measure and Victorian Institute of Sport Assessment-Achilles tendon outcomes, was asymptomatic, and participated in numerous marathons. Improvements were maintained at one-year follow-up. DISCUSSION: Mobility deficits can contribute to the development of tendinopathy, and without addressing movement restrictions, symptoms and functional decline related to tendinopathy may persist. Joint-directed manual therapy may be a beneficial intervention in a comprehensive plan of care in allowing patients with chronic tendon changes to optimize function. LEVEL OF EVIDENCE: Therapy, Level 4.
