Spatiotemporal variability after stroke reflects more than just slow walking velocity Gait Posture (IF 2.4) Pub Date : 2024-03-08 Yogev Koren, Oren Barzel, Lior Shmuelof, Shirley Handelzalts
Increased spatiotemporal gait variability is considered a clinical biomarker of ageing and pathology, and a predictor of future falls. Nevertheless, it is unclear whether the increased spatiotemporal variability observed in persons with stroke is directly related to the pathology or simply reflects their choice of walking velocity. Does increased spatiotemporal gait variability directly relate to motor

Assessing postural control is important for the assessment of motor function after concussion. Data used for postural control assessment typically do not take the sport played, age, or sex of the athlete into consideration. It is plausible these variables may be significant when making return-to-play decisions. This study used the BTrackS database to examine differences in postural control in athletes

Relationships between mediolateral step modulation and clinical balance measures in people with chronic stroke Gait Posture (IF 2.4) Pub Date : 2024-01-16 Keith E. Howard, Nicholas K. Reimold, Heather L. Knight, Aaron E. Embry, Holly A. Knapp, Alexa A. Agne, Camden J. Jacobs, Jesse C. Dean
Many people with chronic stroke (PwCS) exhibit walking balance deficits linked to increased fall risk and decreased balance confidence. One potential contributor to these balance deficits is a decreased ability to modulate mediolateral stepping behavior based on pelvis motion. This behavior, hereby termed mediolateral step modulation, is thought to be an important balance strategy but can be disrupted

Background Clubfoot patients show good-to-excellent foot correction after the Ponseti method. Nevertheless, underlying functional problems that limit motor abilities such as one-leg-standing and one-leg-hopping still persist. These restrictions have been proposed to arise due to problems with maintaining balance and the limited force-generating capacity of clubfoot patients. More insight is needed

Fear of movement has been related to lower limb activation patterns in older adults. However, insight into consecutive perturbations on stepping strategy while considering fall-related confidence is unknown. Are there latency time delays following three consecutive slip perturbations between subjects with and without kinesiophobia when considering limb dominance and fall efficacy differences? There

Reduced center of mass acceleration during regular walking with electromyography biofeedback Gait Posture (IF 2.4) Pub Date : 2024-01-09 Benio Kibushi, Kei Maekaku, Tetsuya Kimura
Background Regular walking in healthy adults is known to be kinematically stable, but it is unclear how to further kinematically stabilize regular walking. Electromyography biofeedback (EMG-BF) during walking improves walking ability in patients. However, the effect of EMG-BF on walking stability in healthy adults is unknown. Therefore, this study aimed to investigate whether EMG-BF enhances the stability

Reversed total shoulder arthroplasty for rotator cuff arthropathy is associated with increased scapulothoracic motion: A longitudinal two-year kinematic study Gait Posture (IF 2.4) Pub Date : 2024-01-12 Nathalie Alexander, Vilijam Zdravkovic, Christian Spross, Martin Olach, Bernhard Jost
Reversed total shoulder arthroplasty (RTSA) is a standard surgical procedure for the treatment of rotator cuff tear arthropathy (CTA), aimed at restoring active arm elevation. Shoulder elevation relies on both scapulothroacic (ST) and glenohumeral (GH) motion, but RTSA computer planning primarily focuses on the GH joint due to challenges in visualizing scapulothroacic (ST) motion. Does the scapulohumeral

Investigation of postural sensory organization in women with and without primary dysmenorrhea in three phases of the menstrual cycle Gait Posture (IF 2.4) Pub Date : 2024-01-12 Emine Baran, Tuğba Yılmaz
The effects of the menstrual cycle in women with and without primary dysmenorrhea on phase-related postural sensory organization are controversial. This study was carried out to examine postural sensory organization in three phases of the menstrual cycle in women with and without primary dysmenorrhea and to evaluate whether there is a difference between women with/without primary dysmenorrhea in this

Effects of structured training on spinal posture and selective motor control in children with unilateral spastic cerebral palsy Gait Posture (IF 2.4) Pub Date : 2024-01-11 Seda Ayaz Taş, Tamer Çankaya
Children with Unilateral Spastic Cerebral Palsy (USCP) have an asymmetrical postural pattern. Although functional limitations are less, deteriorations in spinal posture are observed. What is the effect of structured training on spinal posture and selective motor control of upper extremity? Forty five children with USCP were included in the study. Participants were children ages 3–18 with GMFCS levels

Center of mass motion and plantar pressure distribution during walking in overweight individuals Gait Posture (IF 2.4) Pub Date : 2024-01-05 Hyun Kyung Kim, Hang Qu, Li-Shan Chou
Background Gait imbalance has been reported in overweight individuals and could further impair their mobility and quality of life. As the feet are the most distal part of the body and sensitively interface with external surroundings, evaluating the plantar pressure distribution can provide critical insights into their roles in regulating gait balance control. Therefore, the purpose of this study was
