Manual therapy in joint and nerve structures combined with exercises in the treatment of recurrent ankle sprains: A randomized, controlled trial

Effects of ankle joint mobilization on dynamic balance muscle activity and dynamic balance in persons with chronic ankle instability - Feasibility of a cross-over study

INTRODUCTION

Studies with focus on effects of manual therapy techniques on postural control and muscle activity in patients with chronic ankle instability (are lacking. The purpose of this study was to evaluate the feasibility of a planned cross-over study to assess efficacy of manual therapy techniques applications in patients with chronic ankle instability.

METHODS

This feasibility study used a randomized controlled, blinded assessor cross-over design. Criteria of success under evaluation were adherence and attrition rates and adverse events. while preliminary treatment effects of manual therapy techniques on muscular activity (measured by surface electromyography) and on dynamic balance (measured by time to stabilization test) were secondary aims.

RESULTS

Thirteen participants (mean age: 24.4 ± 3.8 years) with chronic ankle instability volunteered in this feasibility study. Success criteria showed a high adherence (98.7%) and low attrition (0%). No missing data were reported but four out of 26 data sets could not be used for statistical analysis because of non-readability of the recorded data. Preliminary treatment effect showed divergent results for surface electromyography and time to stabilization. One significant result (p = 0.03, ES = 1.48) in peroneus longus muscle activity after jump landing between 30 and 60 ms could be determined.

CONCLUSIONS

This study showed that the study protocol is feasible but should be modified by offering participants the opportunity to familiarize to the jumps and to the test repetitions. This study generates better understanding of manual therapy techniques for patients with chronic ankle instability.

An investigation of neurological and/or biomechanical factors underpinning the effect of a thrust manipulation on chronic ankle symptoms: an observational study

BACKGROUND

Ankle sprains are a commonly occurring musculoskeletal injury potentially resulting in persistent pain and/or altered motion. Thrust manipulation may serve as an interventional strategy but limited evidence exists on the mechanism(s) by which a change to symptoms might occur.

OBJECTIVE

The study sought to quantify the immediate effect of a thrust manipulation to the ankle to determine a mechanism by which change to symptoms occurred.

METHODS

Eleven participants (6 m/5f, 26.09 ± 4.25 yrs) with a history of ankle sprain that occurred greater than three months ago with recurring pain and/or altered motion were recruited. Participants underwent neurophysiological testing to assess any pain alterations and instrumented gait analysis (IGA) for biomechanical assessment pre-post thrust manipulation to the ankle.

RESULTS

There were no significant differences in ankle dorsiflexion (DF) (p = 0.62), plantarflexion (PF) (p = 0.23), ground reaction force (GRF), or velocity (p = 0.63) following thrust manipulation compared to baseline; however, pre- and post-data did show differences in pain pressure threshold (p = 0.046). There were no significant differences in dynamic pain measurements.

CONCLUSIONS

Ankle sprains that result in persistent pain and/or altered motion can be impacted by a thrust manipulation which appears to act through neurophysiological mechanisms.

Adverse Events Reported in Trials Assessing Manual Therapy to the Extremities: A Systematic Review

Objective: This review aimed to describe the quality and comprehensiveness of adverse event (AE) reporting in clinical trials incorporating manual therapy (MT) as an intervention for extremity conditions using the Consolidated Standards of Reporting Trials (CONSORT)-Harms extension as the benchmark. The secondary aim was to determine whether the quality of AE reporting improved after the availability of the CONSORT reporting checklist. Design: Systematic review. Methods: A literature search was conducted using multiple databases to identify trials where MT was used to treat extremity conditions. Studies that reported AEs were identified and evaluated using the CONSORT-Harms extension. The frequency of trials reporting study AEs before and after the publication of the updated 2010 CONSORT statement was calculated, along with the categorization of how study AEs were reported. Results: Of the 55,539 studies initially identified, 220 trials met all inclusion criteria. Eighty trials (36.4%) reported AE occurrence. None of the studies that reported AEs adhered to all 10 criteria proposed by the 2010 CONSORT-Harms extension. The most commonly reported criterion was number four, which clarified how AE-related information was collected (30% of trials). The least reported criterion was number six, which describes the participant withdrawals for each arm due to AEs and the experience with the allocated treatment (1.3% of trials). The nomenclature used to describe AEs varied substantially. Fifty-nine of 76 trials (33.3%) were published after the updated CONSORT Harms-checklist was available, compared to 21 of 44 trials (46.7%) published before it was available. Conclusion: Reporting of AEs in trials investigating MT for extremity conditions is poor. Every included trial lacked adherence to all 10 criteria proposed by the CONSORT-Harms Extension. The quality and comprehensiveness of AE reporting did not improve after the most recent CONSORT update recommending AE reporting. Clinicians must obtain informed consent before performing any intervention, including MT, which requires disclosing potential risks, which could be better known with improved tracking, analyzing, and reporting of AEs. The authors recommend improved adherence to best practices for adequately tracking and reporting AEs in future MT trials.

Effectiveness of Neural Mobilisation on Pain Intensity, Functional Status, and Physical Performance in Adults with Musculoskeletal Pain - A Systematic Review with Meta-Analysis

OBJECTIVE

To investigate up-to-date evidence of the effectiveness of neural mobilisation techniques compared with any type of comparator in improving pain, function, and physical performance in people with musculoskeletal pain.

DATA SOURCES

The following sources were consulted: PubMed, Web of Science, CENTRAL, CINAHL, Scopus, and PEDro databases; scientific repositories; and clinical trial registers. The last search was performed on 01/06/2023.

METHODS

Two reviewers independently assessed the studies for inclusion. We included randomised, quasi-randomised, and crossover trials on musculoskeletal pain in which at least one group received neural mobilisation (alone or as part of multimodal interventions). Meta-analyses were performed where possible. The RoB 2 and the Grading of Recommendations Assessment, Development and Evaluation tools were used to assess risk of bias and to rate the certainty of evidence, respectively.

RESULTS

Thirty-nine trials were identified. There was a significant effect favouring neural mobilisation for pain and function in people with low back pain, but not for flexibility. For neck pain, there was a significant effect favouring neural mobilisation as part of multimodal interventions for pain, but not for function and range of motion. Regarding other musculoskeletal conditions, it was not possible to conclude whether neural mobilisation is effective in improving pain and function. There was very low confidence for all effect estimates.

CONCLUSIONS

Neural mobilisation as part of multimodal interventions appears to have a positive effect on pain for patients with low back pain and neck pain and on function in people with low back pain. For the other musculoskeletal conditions, results are inconclusive.

180-degree immersive VR motion visualization in the treatment of haemophilic ankle arthropathy

BACKGROUND

Patients with haemophilic arthropathy suffer chronic pain that affects and restricts their quality of life. Visualization of movement through immersive virtual reality is used for pain management.

AIM

To evaluate the efficacy of 180-degree immersive VR motion visualization therapy in patients with haemophilic ankle arthropathy.

METHODS

Prospective, multicentre pilot study. Fifteen adult patients with bilateral haemophilic ankle arthropathy were recruited (mean age: 42.73 ± 12.36 years). The intervention lasted 4 weeks, with daily home sessions of 180-degree immersive motion visualization. The patients were given virtual reality glasses to use with their smartphones. From the YouTube mobile app® they accessed the recorded video with access from the He-Mirror App®. The study variables were joint state (Haemophilia Joint Health Score), pressure pain threshold (pressure algometer), muscle strength (dynamometry) and range of motion (goniometry). Three evaluations were performed: at baseline (T0), after the intervention (T1) and at the end of a 16-week follow-up period (T2).

RESULTS

No patient developed ankle hemarthrosis during the experimental phase. In the repeated measures analysis we found statistically significant differences in joint state (F = 51.38; η² _p = .63), pressure pain threshold of the lateral malleolus (F = 12.34; η² _p = .29) and range of motion (F = 11.7; η² _p = .28).

CONCLUSIONS

Therapy using immersive motion visualization does not cause hemarthrosis. This intervention can improve joint condition, pressure pain threshold and range of motion in patients with ankle arthropathy. Changes greater than the MDC were reported in more than 40% of patients for the variables pressure pain threshold, anterior tibialis strength and range of motion, which were considered clinically relevant.

Training-induced hypoalgesia and its potential underlying mechanisms

It is well-established that a single bout of exercise can reduce pain sensitivity (i.e., exercise-induced hypoalgesia) in healthy individuals. However, exercise-induced hypoalgesia is often impaired in individuals with chronic pain. This might suggest that repeated bouts of exercise (i.e., exercise training) are needed in order to induce a reduction in pain sensitivity (i.e., training-induced hypoalgesia) among individuals with chronic pain, given that a single bout of exercise seems to be insufficient to alter pain. However, the effect of repeated bouts of exercise on pain sensitivity and its underlying mechanisms remain poorly understood. Therefore, the purpose of this review was to provide an overview of the existing literature on training-induced hypoalgesia, as well as discuss potential mechanisms of training-induced hypoalgesia and offer considerations for future research. Existing literature suggests that training interventions may induce hypoalgesic adaptations potentially driven by central nervous system and immune system factors. However, the limited number of randomized controlled trials available, along with the lack of understanding of underlying mechanisms, provides a rationale for future research.

The Effect of Manual Therapy Plus Exercise in Patients with Lateral Ankle Sprains: A Critically Appraised Topic with a Meta-Analysis

A high percentage of patients with lateral ankle sprains report poor outcomes and persistent neuromuscular impairment leading to chronic ankle instability and re-injury. Several interventions have been proposed and investigated, but the evidence on manual therapy combined with therapeutic exercise for pain reduction and functional improvement is still uncertain. The purpose was to study the effectiveness of adding manual therapy to therapeutic exercise in patients with lateral ankle sprains through a critically appraised topic. The literature search was performed in PubMed, PEDro, EMBASE and CINAHL databases, and only randomized clinical trials were included according to following criteria: (1) subjects with acute episodes of lateral ankle sprains, (2) administered manual therapy plus therapeutic exercise, (3) comparisons with therapeutic exercise alone and (4) reported outcomes for pain and function. Three randomized clinical trials (for a total of 180 patients) were included in the research. Meta-analyses revealed that manual therapy plus exercise was more effective than only exercises in improving dorsal (MD = 8.79, 95% CI: 6.81, 10.77) and plantar flexion (MD = 8.85, 95% CI 7.07, 10.63), lower limb function (MD = 1.20, 95% CI 0.63, 1.77) and pain (MD = -1.23; 95% IC -1.73, -0.72). Manual therapy can be used with therapeutic exercise to improve clinical outcome in patients with lateral ankle sprains.

Neuromuscular Mechanosensitivity in Subjects with Chronic Ankle Sprain: A Cross-Sectional Study

BACKGROUND

Ankle sprain is one of the most common musculoskeletal injuries in sports, at work, and at home. Subjects who suffer from this injury may develop ankle instability. Functional instability has been associated with a high rate of resprain and impaired neuromuscular control in patients with ankle instability.

OBJECTIVE

Measurement of neural and muscular mechanosensitivity after ankle sprain injury and establishment of the relationship between these variables.

METHODS

A cross-sectional case-control study was performed with a sample of 58 students from Alcalá de Henares University (21 males and 37 females, mean age ± SD = 21 ± 3.7 years). Subjects were divided into two groups: a case group (N = 29, subjects with unstable ankle) and a control group (N = 29, healthy subjects). The pressure pain threshold (PPT) of the tibialis anterior, peroneus longus, and peroneus brevis muscles and mechanosensitivity of the common peroneus and tibial nerves were evaluated in all subjects through a manual mechanical algometer.

RESULTS

Neuromuscular PPTs showed significant differences (P < 0.05) between both groups, such that, compared with the control group, the case group exhibited significantly lower PPT levels. In the case group, a strong positive correlation was observed between neural and muscular homolateral mechanosensitivity in both lower limbs.

CONCLUSIONS

Participants with chronic ankle instability showed higher neuromuscular mechanosensitivity in muscles and nerves surrounding the ankle joint than healthy subjects. These findings indicate that low PPT values may be associated with symptoms that characterize this disease.

The Effects of Therapeutic Exercise With and Without Mobilization in Participants With Chronic Ankle Instability: A Randomized Controlled Trial

Context: Manual therapy (MT) is reported to increase range of motion (ROM), improve balance, and decrease pain in individuals with chronic ankle instability (CAI). Additional literature is needed to examine the effectiveness of the addition of MT to a therapeutic exercise regimen in individuals with CAI. Objective: To examine the combined effects of thrust joint manipulation (TJM) and exercise on function in participants reporting CAI. Design: Randomized controlled trial. Setting: Research laboratory. Participants: A convenience sample of 30 participants (mean age 23.7 [3.65] y; mean height 169.50 [9.50] cm; mean mass 66.48 [10.64] kg). Intervention: Participants were randomly allocated to the exercise (n = 15) or exercise + TJM group (n = 20) and completed an exercise program. The exercise + TJM group also received MT at the talocrural, proximal, and distal tibiofibular joints in the first 3 sessions. Main Outcome Measures: Self-reported outcomes were recorded at baseline and follow-up using the Foot and Ankle Ability Measure (FAAM), the FAAM-Sport (FAAM-S) subscale, and the Ankle Joint Functional Assessment Tool (AJFAT). The side-hop test, figure-of-8 hop test, 3 directions of the Star Excursion Balance Test, and dorsiflexion ROM were also assessed at baseline and follow-up. Results: Only the exercise + TJM group demonstrated an improvement in weight-bearing dorsiflexion with the knee flexed following treatment (P = .02). For all outcome measures, except ROM, subjects improved significantly at follow-up regardless of group assignment (P ≤ .01). Conclusions: Our data suggest that rehabilitation of patients with CAI is related to improved ROM, function, and self-reported outcomes. This provides evidence that the addition of MT to exercise may enhance improvements in ROM as compared with exercise alone. Additional research is needed to identify optimal parameters to maximize therapeutic benefit.

Exercise-Based Rehabilitation and Manual Therapy Compared With Exercise-Based Rehabilitation Alone in the Treatment of Chronic Ankle Instability: A Critically Appraised Topic

Clinical Scenario: Patients with chronic ankle instability (CAI) commonly display lower levels of self-reported function and health-related quality of life. Several rehabilitation interventions, including manual therapy, have been investigated to help CAI patients overcome these deficits. However, it is unclear if the addition of manual therapy to exercise-based rehabilitation is more effective than exercise-based rehabilitation alone. Clinical Question: Does incorporating manual therapy with exercise-based rehabilitation improve patient-reported outcomes when compared with exercise-based rehabilitation alone? Summary of Key Findings: The literature was searched for articles that examined the difference in outcomes for patients with CAI between manual therapy with exercise-based rehabilitation and exercise-based rehabilitation alone. A total of 3 peer-reviewed randomized controlled trials were identified. Two articles demonstrated improved patient-reported outcome scores following the incorporation of manual therapy with exercise-based rehabilitation, whereas one study found no statistically significant differences between interventions. Clinical Bottom Line: The current evidence suggests that incorporating manual therapy in addition to exercised-based rehabilitation may improve patient-reported outcome scores in patients with CAI. Strength of Recommendation: In accordance with the Strength of Recommendation Taxonomy, the grade of A is recommended due to consistent evidence from high-quality studies.

Pressure pain sensitivity over nerve trunk areas and physical performance in amateur male soccer players with and without chronic ankle instability

OBJECTIVE

Chronic ankle instability (CAI) is reported after ankle sprain. Our aim was to assess differences in mechanical pain sensitivity of lower extremity nerve trunks and physical performance between amateur soccer players with and without CAI.

DESIGN

A cross-sectional case-control study.

SETTING

Amateur soccer teams.

PARTICIPANTS

Fifty-five male soccer players, 28 with and 27 without CAI participated.

MAIN OUTCOME MEASURES

The perceived instability was assessed with the Cumberland Ankle Instability Tool (CAIT). Pressure pain thresholds (PPTs) on the common peroneal and tibialis nerve trunks, vertical jump, lateral step-down test and joint position sense of the knee were assessed by a blinded assessor.

RESULTS

Soccer players with CAI showed lower PPTs over the common peroneal nerve than those without CAI (between-groups mean difference: 1.0 ± 0.8 kg/cm², P < 0.001). No differences for PPT over the tibialis posterior (P = 0.078) or any physical performance outcome (knee joint positioning sense [P = 0.798], lateral step-down test [P = 0.580] and vertical jump variables [all, P > 0.310]) were found. PPT over the common peroneal nerve exhibited a significant moderate correlation with the CAIT score (r = 0.528, P < 0.001).

CONCLUSION

Amateur soccer players with CAI have higher pressure pain sensitivity over the common peroneal nerve but exhibit similar physical performance to amateur soccer players without CAI.

Corrective Exercises Improve Movement Efficiency and Sensorimotor Function but Not Fatigue Sensitivity in Chronic Ankle Instability Patients: A Randomized Controlled Trial

OBJECTIVE

To investigate the effect of corrective exercises on functional movement patterns, sensorimotor function, self-reported function, and fatigue sensitivity in collegiate athletes with chronic ankle instability (CAI).

DESIGN

A randomized controlled trial.

SETTING

Laboratory of sports sciences.

PARTICIPANTS

Forty male volunteers were randomly assigned to the experimental group (age 21.2 ± 1.7 years, height 174.5 ± 6.1 cm, and weight 69.6 ± 6.9 kg) or the control group (age 20.9 ± 1.8 years, height 178.2 ± 6.6 cm, and weight 68.8 ± 8.1 kg).

INTERVENTION

Participants in the experimental group performed supervised corrective exercises 3 times per week for 8 weeks. Fatigue was induced with a progressive treadmill protocol before and after the 8-week intervention.

MAIN OUTCOME MEASURES

Outcomes included movement efficiency during 3 squat tasks, static and dynamic postural control, strength of the ankle musculature, joint position sense, and self-reported function with the Foot and Ankle Ability Measure subscales. These outcomes were assessed before and immediately after fatiguing treadmill running both before and after 8-weeks of corrective exercises.

RESULTS

Significant improvements in movement efficiency, sensorimotor function, and self-reported function were noted in the experimental group relative to the control group (P < 0.001), in a nonfatigued state. However, in a fatigued stated, the experimental intervention only improved static postural control (P = 0.016) relative to the control group.

CONCLUSIONS

These findings demonstrate that 8-weeks of corrective exercises were effective at enhancing movement efficiency, sensorimotor function, and self-reported function in collegiate athletes with CAI. However, this intervention program has limited abilities at reducing the effects of fatigue.

Does treatment duration of manual therapy influence functional outcomes for individuals with chronic ankle instability: A systematic review with meta-analysis?

QUESTION

Can manual therapy improve functional outcomes for individuals with chronic ankle instability?

DESIGN

Systematic review with meta-analysis of randomized controlled trials.

PARTICIPANTS

Individuals with chronic ankle instability.

INTERVENTION

Manual therapy is defined as an intervention that involves joint mobilization, and mobilization with movement.

OUTCOME MEASURE

The primary outcome is patient reported function (PRF) questionnaires scores, the secondary outcomes are ankle dorsiflexion range of motion (DFROM) and balance control.

RESULTS

Four studies were included (n = 208, mean age = 24.4) in the meta-analysis, with moderate to high quality on the PEDro scale (range 6-8). For patient reported function (PRF) questionnaires, two studies reported significant improvement after six-session manual therapy measured by foot and ankle ability measures sport subscale (FAAMS) and Cumberland ankle instability tool (CAIT), respectively. For DFROM, one session manual therapy had no significant effect on the weight-bearing lunge test (WBLT) (3 studies, n = 147, SMD = 1.24 (95%CI -0.87 to 3.36), I² = 96%) or non-weight-bearing inclinometer test (2 studies, n = 47, MD = 3.41° (95%CI -0.26 to 7.09),I² = 43%), while six-sessions manual therapy showed, a significantly positive effect on WBLT(2 studies, n = 80, SMD = 2.39, (95% CI 0.55, to 4.23), I² = 93%). For the SEBT, one-session manual therapy had no significant effect on overall star excursion balance test (SEBT) score (3 studies, n = 137,MD = 2.05,95%CI (-0.96,5.05), I² = 75%), while qualitative analysis of 2 included studies showed significant improvement both on the SEBT score and single limb balance test (SLBT).

CONCLUSIONS

Six sessions rather than one session of manual therapy improves ankle functional performance for individuals with CAI.

Tarsal Tunnel Mechanosensitivity Is Increased in Patients with Asthma: A Case-Control Study

Background: Based on changes in lung function and musculoskeletal disorders in patients with asthma, this study aimed to compare the tarsal tunnel and fibular bone pressure pain thresholds (PPTs) of patients with asthma and healthy matched-paired controls. Methods: A case-control study was performed. One hundred participants were recruited: 50 asthma patients and 50 healthy matched-paired controls. Bilaterally, tarsal tunnel and fibula bone PPTs were registered. Results: Statistically significant differences (p < 0.01) were shown bilaterally for tarsal tunnel PPT. With the exception of fibula PPT (p > 0.05), asthma patients presented less tarsal tunnel PPT than healthy participants. Statistically significant differences (p < 0.05) were shown for two linear regression prediction models of the right (R² = 0.279) and left (R² = 0.249) tarsal tunnels PPTs as dependent variables, and based on sex, group, contralateral tarsal tunnel PPT and ipsilateral fibula PPT as independent variables. Conclusions: The study findings showed that a bilateral tarsal tunnel mechanosensitivity increase is exhibited in patients diagnosed with asthma. The presence of asthma may bilaterally predict the PPT of tarsal tunnel. These findings may suggest the presence of central sensitization in asthma patients, which could clinically predispose them to musculoskeletal disorders, such as tarsal tunnel syndrome.

Does Multimodal Rehabilitation for Ankle Instability Improve Patients' Self-assessed Functional Outcomes? A Network Meta-analysis

BACKGROUND

Although there are many nonsurgical treatment options for the primary management of chronic ankle instability, the most effective nonoperative intervention has not been defined.

QUESTIONS/PURPOSES

The purpose of this study was to perform a network meta-analysis to compare the results of different standalone and/or combined nonsurgical interventions on chronic ankle instability as measured by (1) the Cumberland Ankle Instability Tool (CAIT) at 0 to 6 months after treatment and (2) treatment-related complications.

METHODS

We searched PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), and Scopus in August 2017 for completed studies published between 2005 and 2016. We conducted random-effects pairwise and network meta-analysis considering randomized trials, which compared the effects of various nonoperative therapies for ankle instability. Studies assessing patients with functional ankle instability and/or mechanical ankle instability and/or recurrent ankle sprains were eligible for inclusion. After combining data from self-administered questionnaires, we analyzed patient self-reported outcomes of function at the end of the rehabilitation period and 1 to 6 months after treatment. We thereafter reexpressed standardized mean differences to mean differences with CAIT. For this instrument, scores vary between 0 and 30, and higher scores indicate better ankle stability. We included 21 trials involving 789 chronically unstable ankles. The rehabilitation interventions included, but were not limited to, balance training, strengthening exercises, a combination of the balance and strengthening exercises, manual therapy, and multimodal treatment. The implemented multistation protocols were targeted at four main areas of rehabilitation (ROM, balance, strength, and overall activity). Control was defined as placebo and/or wait and see. Treatment-related complications were defined as any major or minor adverse event observed after rehabilitation as reported by the source studies. Statistically, we did not detect significant inconsistency in the network meta-analysis. We also assessed the quality of the trials using the Cochrane risk of bias tool and judged 12, eight, and one studies to be at a low, unclear, and high risk of bias, respectively. We also considered the quality of evidence to be of moderate strength utilizing the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach. We defined the minimum clinically important difference (MCID) in the CAIT to be 3 points.

RESULTS

A 4-week supervised rehabilitation program, which included balance training, strengthening, functional tasks, and ROM exercises, was favored over control according to the results of four trials by a clinically important margin (mean difference between multimodal and control groups in the CAIT was -10; 95% confidence interval [CI], -16 to -3; p = 0.001). Among the standalone interventions, only balance training was better than control according to the findings of seven trials (mean difference between balance training and control in the CAIT was -5; 95% CI, -10 to -0.03; p = 0.049); this difference likewise exceeded the MCID and so is believed to be a clinically important difference. Adverse events associated with the enrolled rehabilitation protocols were transient, mild, and uncommon.

CONCLUSIONS

Although a supervised impairment-based program after chronic ankle instability was superior to control, we note that followup in the included trials tended to be short and inconsistent, although the effect size exceeded the MCID and so likely would be identified as clinically important by patients. Future randomized trials should determine whether the short-term benefits of these interventions are sustained over time.

Equine Manual Therapies in Sport Horse Practice

Manual therapies involve the application of the hands to the body, with a diagnostic or therapeutic intent. Touch therapies, massage, joint mobilization, and manipulation are all critical components in the management of muscular, articular, and neurologic components of select injuries in performance horses. Musculoskeletal conditions that are chronic or recurring, not readily diagnosed, or are not responding to conventional veterinary care may be indicators that manual therapy evaluation and treatment is needed.
