Article Abstract
Objective: To explore the possible association of balance and trunk extensor strength in chronic low back pain (CLBP) patients having tightened hamstring muscle.
Methods: In this correlational study, a total of forty-five patients with CLBP (mean age 38.80 ± 11.14 years) who had hamstring tightness, were examined. A back dynamometer was used to assess trunk extensor strength. The anterior (ANT), posteromedial (PM) and poster lateral (PL) reach distances were measured by Y balance test (YBT). YBT Composite reach distance scores were calculated by the summed average of right/left ANT, PL, and PM normalized to leg length. Uni-variate and multivariate general linear model (GLM) were used to comprehensively examine the best predictors of reach distance performance on YBT.
Results: The mean ± SD age of the patients was 38.80 ± 11.14 years; 68.9% were men. The mean ± SD of composite balance distances and trunk strength scores were 68.23 ± 13.61 and 105.82 ± 54.51, respectively. Trunk extensor strength (β = 9.85, 95% CI: 6.02 to 13.68, p < 0.001) and height of patients (β = 5.25, 95% CI: 1.21 to 9.29, p = 0.012) have positive association with balance whereas individual factors (such as age, gender, weight and BMI) showed no significant association with the balance performance (P > 0.05 for all).
Conclusions: The findings underscore the significant positive association between trunk extensor strength and balance performance, highlighting the potential role of targeted interventions to improve both factors concurrently.

Rear Leg-derived Moment Contributes to Resistance Against Hip Extension in Bulgarian Split Squats.
Int J Exerc Sci
September 2025
Faculty of Health and Sports Science, Juntendo University, Chiba, Japan.
The Bulgarian split squat (BSS) is a unilateral exercise that emphasizes hip extension more than knee extension, compared to other squat variations. This study aimed to (1) empirically verify the existence of the rear leg-derived moment (M)-a theoretically plausible but previously untested external resistive hip moment acting against the net hip extension moment (M) of the front leg-and (2) examine how stance width and forward trunk-leaning angles affect M during the BSS. Nine trained male participants performed bodyweight BSS under two stance conditions (wide and narrow) and three trunk-leaning conditions (additional, natural, and reduced forward lean).

Objective: Backward walking may promote the preferential recruitment of lumbar extensors to optimize flexed spinal posture adopted LBP flexion subgroup. This cross-sectional study investigated the backward-walking exercise on a) real-time muscle activation, and b) its immediate effect on back pain intensity, movement control and lumbopelvic muscle activation in individuals with chronic non-specific LBP characterized with lumbar flexion syndrome.
Method: Thirty adults with chronic non-specific LBP with clinical manifestation of flexion syndrome received assessments of their movement control at static standing and during the five-minute forward walking test, conducted before and after a 15-minute treadmill walking training in forward or backward direction (as the immediate effect), while real-time adaptation of the lumbopelvic muscles during walking training was also evaluated.
Anatomy and pattern of tibial periosteal circulation: implications for tibial plating : a cadaveric study.
Bone Joint Res

Legal Medicine Research Center, Iran Legal Medicine Organization, Tehran, Iran.
Aims: The significance of periosteal vessels in the healing of tibial shaft fractures is well-established. However, the gross anatomical patterns and differential distribution of these vessels on the medial versus lateral surface of the tibial shaft have not been thoroughly described. This study aimed to illustrate the comparative anatomy of periosteal circulation on the medial versus lateral surface of the tibial shaft, where tibial plates are commonly applied.

Objective: To determine if two-dimensional (2D) video-based angular measurements obtained during dynamic tasks predict secondary anterior cruciate ligament (ACL) injury in female athletes post-ACL reconstruction (ACLR).
Methods: Female athletes post-ACLR underwent 2D video assessment during six tasks (step down, drop jump, lateral shuffle, deceleration, triple hop and side-step-cut) before returning to sport. Reinjury status was determined via survey after returning to sport (N=345).
Case Series and Literature Review on Botulinum Toxin Efficacy in Axial Extensor Truncal Dystonia.

Axial truncal dystonia can present as either flexion or extension, often with a tendency toward lateral movement. Flexion dystonia is more common and may represent a clinical spectrum associated with parkinsonism. In contrast, extensor trunk dystonia is less frequent and exhibits a diverse range of causes.
