Varus Thrust Assessment Identified Responders to Quadriceps Exercise in Individuals at Risk of or with Knee Osteoarthritis.

Identification of responders/non-responders to unsupervised therapeutic exercise represents a critical challenge towards establishment of tailored self-management at home. Focusing on visualized varus thrust during gait as a possible effect moderator, this study determined whether and how varus thrust influences the therapeutic effects of home-based quadriceps exercise in individuals at increased risk of, or with, established knee osteoarthritis. This study is a secondary subgroup analysis of a randomized controlled trial (n = 50). Varus thrust at baseline was assessed via recorded gait movie. Analysis of covariance and subsequent mediation analysis were used to determine whether and how varus thrust influences the therapeutic effect of home-based quadriceps exercise after adjustment for covariates. To address the possible distinct impact of varus thrust on unsupervised and supervised exercise, the results were cross-checked with previous supervised exercise cohort using a meta-analysis. Individuals without varus thrust displayed greater and clinically meaningful pain-relief after exercise after adjustment for covariates. The greater pain-relief in individuals without varus thrust was attributed, at least partly, to an improvement in knee flexion range of motion. Notably, the meta-analysis revealed that unsupervised and supervised exercise programs induce consistent and clinically meaningful pain reduction in individuals without varus thrust. Varus thrust is a robust effect moderator of the pain reducing effect of quadriceps exercise. Further, greater pain reduction may be a function of improvement of knee flexion range of motion. These studies provide evidence that varus thrust assessment represents valuable approach to identify responders/non-responders to quadriceps exercise even for unsupervised protocol at their home environment.

Physical Therapists' Prognosis of Outcomes After a Hip or Quadriceps Exercise Intervention in Patients With Patellofemoral Pain: A Secondary Analysis of a Randomized Trial.

OBJECTIVE: Can physical therapists who are treating patients with patellofemoral pain (PFP) predict the outcome of a 12-week exercise intervention based on initial assessment, and what are the physical therapists' reasons for prediction? DESIGN: Secondary analysis of a randomized trial. METHODS: After the initial assessment, physical therapists were asked to predict the prognosis of 200 patients with PFP who were allocated to 12 weeks of quadriceps exercises (QEs) or hip exercises (HEs) on a 1-to-10 Likert scale, and to describe their reasoning for the prediction score. OUTCOMES: measures were changes from baseline to weeks 12 and 26 on the Anterior Knee Pain Scale (range 0-100) and a transition questionnaire (TransQ). Linear mixed-effects models were used to assess the prediction. Secondly, we used a qualitative approach to summarize the physical therapists' reasoning (written notes) when predicting the outcome. RESULTS: There was no association between physical therapists' prognosis and changes in Anterior Knee Pain Scale for QE or HE at weeks 12 and 26 (slopes: -0.14 to -0.51 with wide 95% confidence intervals). There was no association between physical therapists' assessment of prognosis using TransQ for QE or HE at weeks 12 and 26 (odds ratio: 0.99 to 1.17 with wide 95% confidence intervals). CONCLUSION: Physical therapists' prognosis based on initial assessment was not associated with outcomes after 12 weeks of either quadriceps or hip exercise therapy among patients with PFP. Physical therapists' prognoses were not useful as a source of information and to identify PFP patients with poor or good projected outcomes. J Orthop Sports Phys Ther 2024;54(8):541-550.

A Comparison Between Open Kinetic and Closed Kinetic Chain Exercises Along with Conservative Treatment in Grade-I ACL Injury in Sprinters: A Randomized Controlled Trail

Background:Anterior Cruciate Ligament (ACL) injury is most common in sports players such as soccer, basketball, sprinters, which causes alleviated strength in quadriceps muscles, and Range of Motion (ROM) of Knee Joint, and along with this, decrease in efficiency of knee that impacts person’s Activity of daily living (ADL). So, after ACL injury, Rehabilitation protocol plays a great role in maintaining knee ROM, increases the strength of quadriceps muscles. This study aims to compare the effect of open kinetic chain exercises and closed kinetic chain exercises and compare to asses which type of protocol is much efficient for ACL-Injury rehab protocol. Methodology: A comparative study was done over 50 male sprinters of 18-25 years old to assess the effect of Open Kinetic chain exercises (OKC) and closed kinetic chain exercises (CKC). Study was divided into 2 groups: OKC group and CKC group. In OKC Group, subject has to do flexor-extensor bench, isotonic quadriceps exercise and long leg press-off exercises with the conventional physiotherapy whereas in CKC group, subjects has to do wall sits exercises, standing weight shift, one-legged dips exercise, and squatting lunges along with the conventional physiotherapy. Each exercise was performed with 3 sets of 20 repetition, 3 days/week for 45 days. The data was collected from various academies of Satara, Maharashtra after obtaining the ethical permission. Subjects were explained about the procedure and protocol of research. ROM, Numeric Pain Rating Scale (NPRS) and Knee Injury and Osteoarthritis Outcome Score (KOOS) scale were used as Outcome measures. Readings were noted on Day 0 and Day 45. The data was analyzed by using JASP Software. Results: 25 subjects were there in both groups, with the mean age of 23.4 years in CKC group whereas the mean age is 23.44 in OKC group. The mean value of NPRS in OKC group is 4.280±0.843 and that of CKC groups is 4.160±0.624. And the mean value of Knee ROM in CKC group is 118±5 while that of in OKC group is 107.2±4.52. Conclusion: In summary, this study highlights the importance of a tailored rehabilitation program combining OKC and CKC exercises for Grade-I ACL injuries in sprinters. Both exercise types play a crucial role in restoring knee function and strength. As per our study, CKC exercises are better than OKC exercises. So, CKC exercises should be incorporated into rehabilitation program of grade-I ACL injuries.

Longitudinal change in ultrasound-derived rectus femoris cross-sectional area in COPD.

Skeletal muscle dysfunction is common in COPD. Ultrasound-derived rectus femoris cross-sectional area (RFCSA) is a radiation free, non-invasive measure of muscle bulk that relates to quadriceps strength in people with COPD. However, there are limited longitudinal data for RFCSA, and it is not known whether longitudinal change in RFCSA reflects change in quadricep strength, exercise capacity, lower limb function or muscle mass. We aimed to quantify longitudinal change in ultrasound-derived RFCSA and assess its relationship with change in quadriceps maximal voluntary contraction (QMVC), incremental shuttle walk test (ISWT), five-repetition sit-to-stand (5STS) and fat-free mass (FFM) over 12 months in people with COPD. We measured ultrasound-derived RFCSA, QMVC, ISWT, 5STS and FFM (measured by bioelectric impedance analysis) at baseline and 12 months in 169 people with stable COPD. Change was correlated using Pearson's or Spearman's coefficients. Baseline characteristics: mean±sd age 70.4±9.4 years; FEV1 53.3±18.9% predicted. Over the course of 12 months mean RFCSA change was -33.7 mm2 (99% CI -62.6- -4.9 mm2; p=0.003) representing a mean±sd percentage change of -1.8±33.5%. There was a weak correlation between change in RFCSA and FFM (r=0.205, p=0.009), but not with change in QMVC, ISWT or 5STS. There is a statistically significant decrease in ultrasound-derived RFCSA over 12 months in people with stable COPD, but this decrease does not correlate with change in quadriceps strength, exercise capacity, FFM or lower limb function.

The occupation and compliance with quadriceps exercises had a -2.05-correlation coefficient. Weight and compliance with quadriceps strengthening activities have a 2.79 correlation coefficient. Conclusion: Correlation and regression analyses revealed complex relationships between demographics and compliance, emphasizing its pivotal role in predicting recovery impact. Understanding these interactions is vital for tailored rehabilitation after ACL surgery.

Effect of isometric quadriceps exercise on local microcirculation of the infrapatellar fat pad in female patients with knee osteoarthritis

ObjectiveTo elucidate the local microcirculation of the infrapatellar fat pad (IFP) in patients with knee osteoarthritis (KOA) by determining the changes in IFP hardness and hemoglobin concentration during isometric quadriceps exercise (IQE). DesignIn this observational cross-sectional study, patients diagnosed with bilateral KOA were included in the KOA group (30 knees), healthy older adults in the control group (20 knees), and younger adults in the young group (20 knees). Ultrasonography was performed at rest and during IQE to measure IFP hardness based on shear wave velocity. Near-infrared spectroscopy was performed to measure oxygenated hemoglobin (O2Hb), deoxygenated hemoglobin (HHb), and total hemoglobin (cHb) in the IFP before (Baseline), during (IQE task), and after IQE (Post). IFP hardness and O2Hb, HHb, and cHb concentration were analyzed using a linear mixed model for the groups and measurement points. ResultsDuring IQE, IFP hardness changes were significantly less in the KOA group than in the other groups (KOA: 95% confidence intervals (CIs) [−0.854, 0.028]; control: 95% CI [−0.941, −0.341]; and young: 95% CI [−2.305, −1.706]). In the KOA group, O2Hb concentration exhibited no significant changes at Post compared with Baseline; however, significant changes were observed in the other groups (KOA: 95% CI [−1.176, 0.423]; control: 95% CI [−1.452, −0.276]; and young: 95% CI [−4.062, −2.102]). ConclusionsDuring IQE, changes in hardness and hemoglobin concentration in the IFP were not significant in the KOA group, suggesting impaired local microcirculation of the IFP.

Leaf spring exercise: A safe quadriceps strengthening exercise after anterior cruciate ligament reconstruction

BackgroundLeg extensions should be avoided in the early stages after anterior cruciate ligament reconstruction because the force exerted by the quadriceps muscle leads to anterior tibial displacement. To allow for safe quadriceps training in the knee extension range during this period, we devised the leaf spring exercise, which involves placing subjects in the prone position with their knee slightly flexed and instructing them to perform maximum isometric quadriceps contractions while supporting the proximal region of the lower leg's anterior surface and immobilizing the femur's posterior surface to prevent lifting. The current study aimed to examine the safety of Leaf spring exercise by determining the femur–tibia relationship using ultrasound imaging. MethodsThis controlled laboratory study included patients with unilateral anterior cruciate ligament-deficient knees (8 men and 8 women; age, 24.2 ± 8.3 years) who were instructed to perform Leaf spring exercise of both lower limbs. We measured the femur–tibia-step-off, which indicates the distance between the last point of the medial and lateral condyles of the femur and posterior margin of the tibial plateau, as a parameter to evaluate anterior tibial displacement via ultrasound diagnostic device. Further, peak torque of the quadriceps muscle was calculated using force measurement device. FindingsNo difference in anterior tibial displacement and peak torque was observed between the uninjured and injured sides during Leaf spring exercise. InterpretationLeaf spring exercise may add some strain on the reconstructed anterior cruciate ligament; hence, it can be considered a safe quadriceps exercise in the knee extension range.

20 years of neuromuscular electrical stimulation in COPD.

Although a lung disease, COPD is also associated with extrapulmonary manifestations including, among others, limb muscle dysfunction. Limb muscle dysfunction is a key systemic consequence of COPD that impacts patients' physical activity, exercise tolerance, quality of life and survival. Deconditioning is the main mechanism underlying the development of limb muscle dysfunction in COPD, which can be partially improved with exercise. However, some patients may not be able to tolerate exercise because of incapacitating breathlessness or unwillingness to undertake whole-body exercise. Alternative training modalities that do not give rise to dyspnoea, such as neuromuscular electrical stimulation (NMES), are urged. Over the past 20 years, NMES in COPD has presented conflicting conclusions in meta-analysis. In this review, we try to understand the reason for this result by analysing possible biases and factors that brought conflicting conclusions. We discuss the population (the intervention group, but also the control group), the outcome measures, the frequency of stimulation, the rehabilitation protocol (i.e. NMES alone versus standard care/rehabilitation or NMES plus conventional exercise training versus conventional exercise training alone or NMES versus sham treatment) and the trial design. The main reason for this discrepancy is the lack of dedicated guidelines for NMES. Further research is urged to determine the optimal parameters for an NMES programme. Despite this, NMES appears to be an effective means of enhancing quadriceps strength and exercise capacity in COPD with the potential to break the vicious circle induced by the disease and COPD patients' lifestyle.

Background: Osteoarthritis (OA) of the knee is prevalent in the elderly and causes pain, stiffness, and functionallimitations. Hamstring inflexibility and weakened quadriceps worsen OA progression. Hence, Therapeuticinterventions like IASTM and Static Stretching show potential in addressing musculoskeletal issues.Objective: This study aimed to investigate and compare the effectiveness of IASTM versus Static Stretching, alongwith quadriceps strengthening exercises and TENS, in improving hamstring flexibility, and quadriceps strength,and reducing pain in patients with knee OA.Methodology: A randomized controlled trial with 30 knee OA patients: Group A (n=15) received IASTM,quadriceps strengthening exercises, and TENS; Group B (n=15) underwent Static Stretching, quadriceps exercises,and TENS. Both groups underwent a six-week intervention program, with pre-and post-assessments using NPRS,AKE Test, and WOMAC questionnaire.Results: Significant differences were observed between Group A and Group B in NPRS, AKE Test, and WOMACscores (p < 0.0001). Group A exhibited lower values in NPRS, AKE Test, and WOMAC, indicating reduced pain,improved knee function, and decreased discomfort compared to Group B. The combination of interventions inGroup A appeared to offer better outcomes for knee OA patients.Conclusion: The study suggests that the combination of IASTM, quadriceps strengthening exercises, and TENS(Group A) yields better outcomes in improving knee OA patients’ hamstring flexibility, quadriceps strength, andpain reduction compared to Group B.

Normative values for isometric quadriceps peak torque using fixed dynamometry in healthy young adults

RATIONALE: Assessment of muscle strength is recommended to measure weakness and inform exercise prescription in adults undergoing pulmonary rehabilitation. There is a lack of normative data for lower extremity muscle strength using fixed dynamometry in the clinical setting in young adults. OBJECTIVES: Primary objectives were to determine (i) normative values for isometric quadriceps peak torque (QT) using fixed dynamometry and (ii) the relationship between isometric QT with demographics, body composition, habitual physical activity and one-repetition maximum (1-RM) for knee extension. A secondary objective was to develop a preliminary equation to predict 1-RM knee extension using isometric QT. METHODS This was a cross-sectional study of healthy adults aged 18–39 years. Isometric QT was assessed using fixed dynamometry (MedUp®). A 1-RM test was performed in the same setting. Age, sex and body composition using bioelectiral impedance analysis (Tanita, DC-430U) were collected. Physical activity was assessed by the Rapid Assessment of Physical Activity (RAPA). RESULTS Eighty-two participants were included (44 females, 54%). Isometric QT was 89 (77-132) Nm for females and 158 (133-187) Nm for males (p < 0.0001). There was a strong correlation between isometric QT and 1-RM (r = 0.85, p < 0.0001). The multi-linear regression model to predict 1-RM included sex, isometric QT and BMI (F (3, 78) = 60.819; p < 0.001; R 2 = 0.701). CONCLUSION Normative isometric QT values to quantify lower limb strength impairment and a preliminary equation using isometric QT to predict 1-RM and prescribe resistance quadriceps exercise training may inform pulmonary rehabilitation programs for a younger respiratory population. Validation of the 1-RM equation in clinical populations is needed.

Effects of Isometric Quadriceps Muscle Exercise with Visual and Auditory Feedback at 1 Year after Total Knee Arthroplasty.

To examine the effect of isometric quadriceps exercises with visual and auditory feedback after total knee arthroplasty (TKA). The sample included 41 patients from our previous study who could be followed up for 1 year after TKA. Patients in the intervention group performed isometric quadriceps exercises with visual and auditory feedback using the quadriceps training machine from the 2nd to the 14th day after TKA, whereas those in the control group underwent standard postoperative rehabilitation (without visual or auditory feedback during isometric quadriceps exercises) in the hospital. Patients were evaluated for pain intensity, timed up and go test (TUG) score, 10-m gait speed, 6-minute walking distance (6MWD), and the Western Ontario and McMaster University Osteoarthritis Index (WOMAC) score 1 year after TKA. Additionally, exercise habits and responses to the International Physical Activity Questionnaire (IPAQ) were investigated. Pain intensity was significantly lower in the intervention group than in the control group. Greater improvements in the TUG test scores, 10-m gait speed, 6MWD, and WOMAC scores were observed in the intervention group. Walking activity, as recorded by the IPAQ, and the proportion of patients with exercise habits were significantly higher in the intervention group than in the control group. These results suggest that performing isometric quadriceps exercise with visual and auditory feedback using the quadriceps training machine has good effects, such as pain reduction, physical function improvement, exercise tolerance, and increased physical activity at 1 year after TKA.

Efficacy of Post-Operative Logbook-Based Quadriceps Exercises on Functional Outcome after Total Knee Arthroplasty

Purpose: Most patients who undergo total knee arthroplasty (TKA) are elderly. Some patients have recognition impairments and cannot correctly perform home-based rehabilitation effectively. This study aimed to compare the functional outcomes between logbook- and non-logbook-based quadricep exercises. Methods: In this prospective cohort study with retrospective case controls scheduled for unilateral primary/bilateral TKA, we compared 57 patients who received post-operative home-based rehabilitation and seated knee extension exercises (non-logbook group) with 60 patients who received the same protocol but were provided a logbook with paper handouts containing the schedule, date, time, and record form (logbook group). The modified Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores and data pertaining to range of motion (ROM) were collected pre-operatively and at 6, 12, and 24 weeks post-operatively. Results: The logbook group showed a significant improvement in the mean difference in function and total WOMAC scores at 6-weeks post-operatively (p &lt; 0.05). There was no significant difference in the pre- and post-operative ROM at any follow-up time point between the groups. Conclusions: Logbook-based quadriceps exercises resulted in significant early improvement in the functional outcomes. Logbooks may help patients who have undergone TKA to perform their home-based exercise regimens accurately.
