Influence of symptom frequency and severity on hip abductor strength and endurance in individuals with patellofemoral pain

Abstract Background Persons aged ≥ 65 years are currently the world’s fastest growing age group. An important complication of age is the increasing risk of falls. Falls have multifactorial etiology and modifiable risk factors open for interventions in prevention and rehabilitation, are of high interest. In this context, strong hip abductors seem to be important to prevent falls. A newly adapted measurement device to measure hip abductor strength (HAS) in a closed chain position was developed. We aim to assess feasibility, intra- and inter-tester reliability and construct and criterion validity of the new measure. Methods In two subsequent parts a feasibility, reliability and validity study with an adapted measurement instrument for the assessment of HAS (index test) in a closed chain position in persons aged ≥ 65 years will be conducted. Part I investigates feasibility of the measure in clinical settings as well as reliability of the new HAS test (n = 26). Part II evaluates construct and criterion validity (n = 169). Construct validity will be assessed cross-sectional, criterion validity by comparison with prospectively followed up fall history for 12 months (external criterion) and other functional fall risk assessments (Short Physical Performance Battery, Timed Up and Go test, usual gait speed and hand grip strength). Discussion Results of feasibility, will give insight in its applicability in daily clinical life and clinimetric properties will show if measurements of HAS in a closed chain position should be encouraged to include in fall risk assessments in older adults.

Abstract Context: Very few authors have investigated the relationship between hip-abductor muscle strength and frontal-plane knee mechanics during running. Objective: To investigate this relationship using a 3-week hip-abductor muscle-strengthening program to identify changes in strength, pain, and biomechanics in runners with patellofemoral pain syndrome (PFPS). Design: Cohort study. Setting: University-based clinical research laboratory. Patients or Other Participants: Fifteen individuals (5 men, 10 women) with PFPS and 10 individuals without PFPS (4 men, 6 women) participated. Intervention(s): The patients with PFPS completed a 3-week hip-abductor strengthening protocol; control participants did not. Main Outcome Measure(s): The dependent variables of interest were maximal isometric hip-abductor muscle strength, 2-dimensional peak knee genu valgum angle, and stride-to-stride knee-joint variability. All measures were recorded at baseline and 3 weeks later. Between-groups differences were compared using repeated-measures analyses of variance. Results: At baseline, the PFPS group exhibited reduced strength, no difference in peak genu valgum angle, and increased stride-to-stride knee-joint variability compared with the control group. After the 3-week protocol, the PFPS group demonstrated increased strength, less pain, no change in peak genu valgum angle, and reduced stride-to-stride knee-joint variability compared with baseline. Conclusions: A 3-week hip-abductor muscle-strengthening protocol was effective in increasing muscle strength and decreasing pain and stride-to-stride knee-joint variability in individuals with PFPS. However, concomitant changes in peak knee genu valgum angle were not observed.

Abductor Strength

IntroductionConservation of abductor muscle strength is directly associated with physical function after total hip replacement (THA). Although many studies have tried to explore and quantify a potential abductor muscle strength deficit after THA as well as identify possible causes and treatment options, this topic has not been addressed systematically.Methods and analysisHuman-based studies reporting measurements of hip abductor strength will be included in this review. Studies reporting on hip abductor strength measured manually or isometric measurements at an abduction angle other than 0° will not be considered. No restriction will be placed on study design, publication date operative approach, prosthesis design, age and sex of the patients or severity of OA. Data sources will be Embase via embase.com, Medline ALL via Ovid and the Cochrane Central Register of Controlled Trials. The preliminary search was conducted on 5 May 2019. Data regarding absolute values or torque ratio of hip abductor torque between sides as well as patient demographic data, surgical approaches and rehabilitation protocols will be extracted. The assessment of quality and risk of bias will be performed with the modified Newcastle-Ottawa Scale. The screening, data extraction and quality assessment will be performed by two reviewers independently. Where necessary, a third review author will make a final judgement. Narrative synthesis as well as tabular presentation of the extracted data will be included. Whenever possible, metaregression and subgroup specific meta-analyses will be used to investigate the influence of time since THA and type of measurement (isokinetic or isometric) on the different outcomes. In case of sufficient information, these analyses will be extended to include characteristics such as age, sex, surgical approach or rehabilitation programme.Ethics and disseminationNo ethics approval is required. The results will be disseminated through peer-reviewed publications and conference presentations.PROSPERO registration numberCRD42020153185.

Abstract Purpose: To investigate the influence of additional eccentric strengthening to the hip abductor and lateral rotator musculature on pain and function in sedentary people with Patellofemoral pain syndrome (PFPS). Methods: 30 sedentary patients between 18 and 40 years of age, with a diagnosis of PFPS, all the subjects received treatment for a period of 4weeks and the subjects were randomly assigned to Control group (CG) and Experimental group (EG). The patients in the Control group (n = 15) performed a conventional knee-stretching and strengthening program, whereas, patients in the Experimental group (n = 15) performed the same exercises as those in the control group ,in addition received eccentric strengthening exercises for the hip abductors and lateral rotators. An 11-point numeric pain rating scale (NPRS), the Lower Extremity Functional Scale (LEFS) and the Anterior Knee Pain Scale (AKPS) were used as outcome measures during the baseline and at the end of 4weeks . Results: Statistics were retrieved using SPSS.16, paired 't' test was conducted to compare AKPS and LEFS values ,whereas, Mann- Whitney U test was used for NPRS value between the groups. After 4 weeks of treatment, the control group, pre and post-test value for AKPS (p<0.001),LEFS (P<0.001),NPRS (p<0.001) shows a statistical significance and even in the experimental group, pre and post-test value for AKPS (p<0.001),LEFS (P<0.001),NPRS (p<0.001) shows a statistical significance in pain and function, but comparing both the group experimental group is significantly more better AKPS (p=0.002),LEFS (P<0.001),NPRS (P<0.001) then a control group. Conclusion: short term Knee strengthening exercises supplemented by eccentric hip abductor and lateral rotator musculature–strengthening exercises were more effective than knee exercises alone in improving function and reducing pain in sedentary people with PFPS.
