This study evaluates the validity and reliability of a portable strain gauge dynamometer compared with a gold-standard instrumented dynamometer. Thirty-five healthy adults were divided into 2 groups: one for validation against the reference device and another for test-retest reliability assessment. Pearson correlations, Bland-Altman analyses, and intraclass correlation coefficients were performed on plantar flexor maximal force and torque data. A strong correlation (r = .84, 95% CI: .59-.94, P < .001) confirmed the portable strain gauge dynamometer's validity, with a slight torque underestimation (-4.6% [20.5%]). Bland-Altman analysis indicated a mean bias of -4.34 N·m with 95% limits of agreement ranging from -27.9 to 19.2 N·m. Reliability was excellent across sessions and raters (intraclass correlation coefficients = .889-.926; standard error of measurement = 43.2-55.6 N·m). Absolute reliability analyses suggested that only changes above ∼120 to 155 N exceeded measurement error. These results support that the strain gauge dynamometer, fixed to a stable surface, is a valid and reliable tool for assessing plantar flexor strength in clinical settings.","PeriodicalId":54883,"journal":{"name":"Journal of Applied Biomechanics","volume":" ","pages":"393-400"},"PeriodicalIF":1.6,"publicationDate":"2026-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147846302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Individuals with lower limb amputation (LLA) have demonstrated larger WBAM ranges during walking relative to uninjured controls, suggesting disrupted WBAM control.

Linear regressions revealed weak relationships (R2 = .050-.350, P < .071), particularly in the sagittal and transverse planes, between trunk postural control measures and WBAM ranges. Trunk postural control measures during unstable sitting were larger among individuals with LLA versus uninjured controls (P < .029) but were not different between individuals with transtibial amputation versus transfemoral amputation. Similarly, WBAM ranges during walking were larger in all planes between individuals with LLA versus uninjured controls (P < .005), with individuals with transtibial amputation having larger ranges than individuals with transfemoral amputation in the sagittal (P < .001) and frontal (P = .006) but not the transverse (P = 1.000) planes.

We propose harnessing the technology embedded in earbuds to capture fundamental aspects of running mechanics and make them available to the wider community of users, outside a lab setting. While other wearables such as insoles or ankle-/sacrum-mounted inertial measurement units have already been presented, ear-worn devices may have a better potential for adoption and therefore offer an optimal compromise between validity of running gait analysis and usability. Thirty healthy participants (18 males, 12 females) ran on an instrumented treadmill (54,000 gait cycles) and floor-mounted force plates (2800 gait cycles) at a variety of speeds. Building on the information brought about by the vibrations transmitted to, and motion of, the head, we devised a gait event detection algorithm and a regression model to predict vertical ground reaction force waveforms. The validation of outcomes against quantities from force plates shows an average mean absolute percentage error of 4.8% on temporal metrics and 9.0% on scalar ground reaction force derived metrics. Additionally, the model tracks the full vertical ground reaction force curve well, achieving an normalized root mean square error of 11.1% on unseen participants. Overall, we show comparable accuracy from an ear-worn consumer device in temporal and kinetic gait parameter estimation to specialist devices, paving the way for accessible running gait monitoring.","PeriodicalId":54883,"journal":{"name":"Journal of Applied Biomechanics","volume":" ","pages":"383-392"},"PeriodicalIF":1.6,"publicationDate":"2026-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147789322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Correlation coefficients assessed associations between proximal and distal variables, and significant variables were entered into a hierarchical regression to determine their contribution to shoulder IR angular velocity. Results revealed a proximal-to-distal sequence pattern. Central/back players demonstrated higher peak angular velocities in most segments, along with increased range of motion in the hip, pelvis, and thorax. Hip and pelvis kinematics explained 44% of the variance in peak shoulder IR angular velocity (R2 = .44, P = .001).

Walking breaks can reduce standing-induced LBP. Although LBP and walking are typically studied in the context of chronic pain, the standing-induced pain model can establish whether altered gait mechanics precede pain and whether movement after standing reduces pain. This study used a standing-induced LBP paradigm to assess effects of standing on spatiotemporal gait parameters and trunk-pelvis kinematics. Participants stood for 75 minutes completing computer tasks, with prestanding and poststanding walking recorded using markerless motion capture. Ten of 31 participants developed LBP during standing; however, their gait changes differed from those in the literature for chronic LBP. Pain-developing participants showed less trunk-pelvis lateral bend deviation angle during walking. Trunk axial twist deviation phase angle increased, which may signal a redistribution of force across different tissues following a pain-inducing task or reduced function of the deep stabilizer muscles of the spine, resulting in more movement variability. Future work will measure muscle activity throughout walking and standing to link kinematics and muscle activity and explore whether walking at different speeds may alter pain development.","PeriodicalId":54883,"journal":{"name":"Journal of Applied Biomechanics","volume":" ","pages":"357-368"},"PeriodicalIF":1.6,"publicationDate":"2026-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147700739","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Knee OA participants were randomized into Tai Chi or control (balance and postural training) groups, receiving 12-week interventions. 3D motion analysis assessed interjoint coordination via perimeter, area, and coordination coefficient of cyclogram at baseline and postintervention. Compared with healthy elderly, individuals with knee OA exhibited greater sagittal plane joint excursions, increased hip-knee angular range, and less smooth cyclograms. Postintervention, both groups exhibited reduced excursions in the sagittal and frontal planes, with greater reductions observed in the control group. The Tai Chi group showed decreased hip-ankle and knee-ankle angular ranges, whereas the control group displayed reduced hip-knee ranges, both shifting coordination parameters toward healthy levels. Only the sagittal plane hip-knee cyclogram area differed significantly between interventions, being smaller in the balance group. Knee OA impairs stair ascent coordination in elderly. Both interventions enhance coordination, but Tai Chi's benefits are predominantly sagittal specific, whereas balance training improves both planes and demonstrates superior efficacy in improving hip-knee flexion-extension coordination.","PeriodicalId":54883,"journal":{"name":"Journal of Applied Biomechanics","volume":" ","pages":"246-258"},"PeriodicalIF":1.6,"publicationDate":"2026-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147596312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sixteen collegiate cross-country runners (8 females) participated. A self-selected running speed was entered into regression equations to determine treadmill speeds for the conditions: recovery (∼9% slower), threshold (∼25% faster), interval (∼36% faster), and repetition (∼50% faster). Three-dimensional lower-extremity biomechanics were collected during running. Dependent variables were analyzed via mixed-model analysis of variance and pairwise post hoc tests. Both peak rearfoot angle increased (P = .005, Cohen's f = 0.84) and rearfoot excursion increased (P = .002, Cohen's f = 0.88) with the conditions' treadmill speed. Peak knee adduction angle was greater in females compared with males (P = .032, Cohen's f = 0.67) during: recovery, easy, threshold, and interval conditions. Increases in running speed affected joint kinematics and kinetics similarly between groups. Generally, similar running biomechanics observed between females and males may indicate that faster training speeds could accentuate the contribution of rearfoot eversion to lower leg overuse injury.","PeriodicalId":54883,"journal":{"name":"Journal of Applied Biomechanics","volume":" ","pages":"267-272"},"PeriodicalIF":1.6,"publicationDate":"2026-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147522807","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Topics discussed in interviews included aspirations, mental focus, potential for injury, and perceptions of contact. Athletes with the greatest HAE frequency discussed wanting to advance to higher levels of football (eg, college). Several athletes expressed an affinity for contact, many of whom had more HAEs per session than other athletes; however, some athletes disliked the risk of injury in football. Athletes reported that hits to the head felt the hardest, consistent with greater magnitudes measured among head impacts compared with body impacts.
