Lower extremity gait kinematics outcomes after knee replacement demonstrate arthroplasty-specific differences between unicondylar and total knee arthroplasty: A pilot study.

The aim of the present study is to compare sagittal gait kinematics of ankle, knee and hip joints between subjects with unicondylar and total knee arthroplasty and age matched healthy controls. Since unicondylar knee replacement is a less invasive procedure, which more closely preserves knee joint anatomy, we hypothesized that one year post unicondylar knee arthroplasty patients would demonstrate more normal gait patterns than patients with total knee arthroplasty.

Study on gait symmetry based on simulation and evaluation system of prosthesis gait.

A software and hardware platform for gait simulation and system evaluation for lower limb intelligent prosthesis is proposed and designed, in order that the wearable symmetry effect of the intelligent knee prosthesis can be quantitatively analyzed by machine test instead of human wear test. The whole-body three-dimensional gait and motion analysis system instrument, a device to collect gait data such as joint angle and stride of adults, was used for extracting simulated gait characteristic curve. Then, the ...

Quantitative evaluation of gait features after total knee arthroplasty: Comparison with age and sex-matched controls.

Gait function after total knee arthroplasty (TKA) is suboptimal. However, quantified analysis with comparing a control group is lacking.

Visual kinematic feedback enhances the execution of a novel knee flexion gait pattern in children and adolescents.

Altered knee motion is one of the most common gait deviations in pediatric populations with gait disorders. The potential for pediatric gait retraining using visual feedback based on knee kinematic patterns is under-explored.

Association of Knee Pain and Crouch Gait in Individuals With Cerebral Palsy.

Crouch gait (ie, excessive knee flexion) is commonly seen in patients with cerebral palsy (CP) and has been inconsistently linked with knee pain. The definitive cause of knee pain is unknown, but may result from increased joint forces due to crouch gait kinematics. Our purpose was to determine whether knee pain is positively associated with knee flexion in gait among a large sample of ambulatory individuals with CP. We hypothesized that knee pain prevalence would increase as knee flexion increased.

Gait and Functional Outcomes Between Cruciate-Retaining and Cruciate-Substituting Implants in Total Knee Arthroplasty: A Prospective, Randomized Study.

Significant debate persists about posterior cruciate-retaining (CR) versus posterior cruciate-substituting (PS) implant design for total knee arthroplasty (TKA). This study sought to test the hypothesis that CR TKA will facilitate improved early functional outcomes in gait compared with PS TKA. Patients were randomized to either the CR or PS implant. Various patient-reported and surgeon-reported outcomes as well as gait analyses were obtained pre- and postoperatively. Patients undergoing PS TKA had higher U...

No association between preoperative physical activity level and time to return to work in patients after total hip or knee arthroplasty: A prospective cohort study.

It is important for patients of working age to resume work after total hip or knee arthroplasty (THA/TKA). A higher preoperative level of physical activity is presumed to lead to a better or faster recovery. Aim is to examine the association between preoperative physical activity (PA) level (total and leisure-time) and time to return-to-work (RTW).

Measures of knee and gait function and radiographic severity of knee osteoarthritis - A cross-sectional study.

Pain reports show at most weak to moderate relationship with structural findings of knee osteoarthritis (OA). Less is known about the relationship between measures of knee and gait function and structural findings of knee OA.

Predicting physical activity recovery after hip and knee arthroplasty? A longitudinal cohort study.

Recovery of physical activity (PA) after telerehabilitation following knee and hip arthroplasty (TKA-THA) has rarely been studied. An improved understanding of PA recovery is needed, as it could be influenced by many factors such as age, gender or pre-operative physical function.

Impact of instrumental analysis of stiff knee gait on treatment appropriateness and associated costs in stroke patients.

Stiff Knee Gait (SKG) in stroke patients is typically treated by the inhibition of the rectus femoris (RF) with botulinum toxin (BoNT) after clinical evaluation, obtaining an average pooled recovery in knee flexion (KF) of 7 degrees.

The influence of sex and pre-operative obesity on biomechanics two years after total knee arthroplasty: A longitudinal cohort study.

Sex and obesity may influence knee biomechanics associated with poor outcomes following primary total knee arthroplasty (TKA) however their long-term impact has not been investigated.

No shortage of disagreement between biomechanical and clinical hop symmetry after anterior cruciate ligament reconstruction.

Evaluating average performance on functional hop tasks can potentially overestimate physical function, as it masks variability present within individual trials and may lead to clinician oversight regarding the overall movement quality. The purpose was to evaluate the trial-by-trial agreement between hop-distance symmetry and knee biomechanics (knee flexion angle, knee extension moment) to reveal the full extent of agreement between these measures.

Perceived barriers to and facilitators of physical activity in people with knee osteoarthritis: development of the Evaluation of the Perception of Physical Activity questionnaire.

The physical activity (PA) level of individuals with knee osteoarthritis is lower than in the general population. International recommendations recommend a non-pharmacological intervention including a self-management education program, weight loss and an adapted exercise program. However, we have no scale assessing the perceived barriers to and facilitators of PA in this population.

The effects of arm swing amplitude and lower-limb asymmetry on gait stability.

Changes to arm swing and gait symmetry are symptomatic of several pathological gaits associated with reduced stability. The purpose of this study was to examine the relative contributions of arm swing and gait symmetry towards gait stability. We theorized that actively increasing arm swing would increase gait stability, while asymmetric walking would decrease gait stability. Fifteen healthy, young adults (23.4 ± 2.8 yrs) walked on a split-belt treadmill under symmetric (1.2 m/s) and asymmetric walking (lef...

Knee adduction moments are not increased in obese knee osteoarthritis patients during stair negotiation.

Negotiating stairs is an important activity of daily living that is also associated with large loads on the knee joint. In medial compartment knee osteoarthritis, the knee adduction moment during level walking is considered a marker for disease severity. It could be argued that the discriminative capability of this parameter is even better if tested in a strenuous stair negotiation task.

Improving the Patient Experience Following Total Knee and Total Hip Arthroplasty: A Practice Development Project.

The paradigm shift that has occurred for patients with total hip (THA) and knee (TKA) arthroplasty through enhanced recovery programs underscores the need for redesigning care provision.

Hybrid Assistive Limb improves restricted hip extension after total hip arthroplasty.

The Hybrid Assistive Limb (HAL) was developed as an exoskeleton robot that supports gait training. The purpose of this study was to assess the usefulness of training using the HAL after total hip arthroplasty (THA). We targeted 16 consecutive patients who underwent THA via the posterior approach. We randomized patients to the HAL group (8 hips), in which the HAL was used as part of physical therapy, or the control group (8 hips), in which only typical physical therapy was performed. Gait analysis was perfor...

Effects of Home- and Center-Based Exercise Programs on the Strength, Function, and Gait of Prefrail Older Women: A Randomized Control Trial.

The aims of this study were to compare the effects of a multicomponent exercise program provided at a center (CB) versus done part at home and part at a center (H+CB) on frailty status, strength, physical function, and gait of prefrail older women. Twenty-five women were randomly allocated into the CB (n = 14; 69 ± 6 years) and the H+CB (n = 11; 69 ± 7 years) groups. Both groups completed an exercise program including strengthening, balance, and gait exercises. The program was 12 weeks long, done three ti...

Effect of altered sagittal-plane knee kinematics on loading during the early stance phase of gait.

Individuals with knee osteoarthritis (OA) show various dynamic sagittal-plane changes during the early stance phase of gait. However, the effect of these kinematic alterations on knee load during the early stance remains poorly understood.

Effects of a corrective heel lift with an orthopaedic walking boot on joint mechanics and symmetry during gait.

Orthopaedic walking boots are commonly prescribed following injury and surgery. The boot creates a leg length discrepancy which is thought to affect limb symmetry and gait mechanics. This study aimed to examine the effects of a corrective heel lift for the contralateral limb on the mechanics and symmetry of walking with an orthopaedic walking boot.

Examining Timeliness of Total Knee Replacement Among Patients with Knee Osteoarthritis in the U.S.: Results from the OAI and MOST Longitudinal Cohorts.

Patients with knee osteoarthritis may undergo total knee replacement too early or may delay or underuse this procedure. We quantified these categories of total knee replacement utilization in 2 cohorts of participants with knee osteoarthritis and investigated factors associated with each category.

Effects of Vibrotactile Biofeedback Coding Schemes on Gait Symmetry Training of Individuals with Stroke.

Variations in biofeedback coding schemes for postural control, in recent research, have shown significant differences in performance outcomes due to variations in coding schemes. However, the application of vibrotactile biofeedback coding schemes to gait symmetry training is not well explored. In this paper, we devised various vibrotactile biofeedback modes and identified their efficacy during gait symmetry training of individuals suffering from hemiparesis due to stroke. These modes are composed of variati...

Association of Total Daily Physical Activity and Fragmented Physical Activity With Mortality in Older Adults.

Fragmented daily physical activity may be a sign of physiological decline that provides more powerful insight into impending mortality than total daily activity.


Gait asymmetries are a matter of discussion concerning gait adaptation in older adults. While most studies perform unilateral gait assessments, the hypothesis that asymmetry in gait biomechanics is influenced by muscular and functional performance in older people needs to be confirmed.

Knee joint biomechanics in transtibial amputees in gait, cycling, and elliptical training.

Transtibial amputees may experience decreased quality of life due to increased risk of knee joint osteoarthritis (OA). No prior studies have compared knee joint biomechanics for the same group of transtibial amputees in gait, cycling, and elliptical training. Thus, the goal of this study was to identify preferred exercises for transtibial amputees in the context of reducing risk of knee OA. The hypotheses were: 1) knee biomechanics would differ due to participant status (amputee, control), exercise, and leg...
