BACKGROUND DATA Lumbar segmental instability (LSI) is one of the subgroups of non-specific chronic low back pain. Pain, functional disability and reduced muscle endurance are common in such patients. OBJECTIVE The aim of this study was to determine the effects of stabilization exercise on pain, functional disability and muscle endurance in patients with LSI. METHODS A randomized clinical tr...

BACKGROUND Stabilization exercises can improve the performance of trunk and back muscles, which are effective in the prevention and treatment of low back pain. The four-point kneeling exercise is one of the most common types of stabilization exercises. This quasi-experimental study aimed to evaluate and compare the level of activation between abdominal and lumbar muscles in the different stages...

Background: This study conducted to find out the effectiveness of trunk flexion rotation, extension rotation and combined flexion rotation & extension rotation exercises in reduction of scoliosis. Twenty five male scoliotic subjects secondary to post-polio residual paralysis were selected for the study as per the inclusion and exclusion criteria. Method: Materials used for the study were Rontge...

[Purpose] This study investigated the effect of shoulder girdle strengthening, particularly the scapular muscles, on poststroke trunk alignment. [Subjects and Methods] The study involved 30 patients with residual hemiparesis following cerebrovascular stroke. Patient assessment included measuring shoulder muscle peak torque, scapular muscles peak force, spinal lateral deviation angle, and motor ...

[Purpose] This study investigated the changes in the muscle activities of the trunk and lower limbs of healthy adults during a one-legged bridge exercise using a sling, and with the addition of hip abduction. [Subjects and Methods] Twenty-seven healthy individuals participated in this study (14 males and 13 females). The participants were instructed to perform the bridge exercises under five di...

Background. Middle-aged women are at risk of musculoskeletal disorders because of the decreased muscle mass and bone density caused by a decreased endocrine function. Objectives. This study investigated the effectiveness of a stabilization exercise using respiratory resistance on female patients in their 40s with low back pain. Methods. Forty-four female patients in their 40s with low back pa...

Between different modelling of animal hopping, walking and running, the most popular one is Spring Loaded Inverted Pendulum (SLIP) model [1],[2]. Through the representation of the body in SLIP by a point mass, trunk stabilization is not addressed. With addition of trunk, it is extended to TSLIP (Trunk SLIP) in which hip torque is applicable for control. Mostly, the control is performed in two l...

The purpose of this investigation was to compare trunk muscle activity during stability ball and free weight exercises. Nine resistance-trained men participated in one testing session in which squats (SQ) and deadlifts (DL) were completed with loads of approximately 50, 70, 90, and 100% of one-repetition maximum (1RM). Isometric contractions during 3 stability ball exercises (quadruped (QP), pe...

The purpose of this study was to compare the effects of lumbar stabilization exercises using balls to the effects of general lumbar stabilization exercises with respect to changes in the cross section of the multifidus (MF), weight bearing, pain, and functional disorders in patients with non-specific chronic low back pain. Twelve patients participated in either a 8 week (3 days per week) stabil...

[Purpose] This study aimed to develop unilateral exercises for urban drivers and investigate the effect of these exercises on low back pain (LBP). [Subject and Methods] A 40-year-old male driver, who complained of LBP on the left side at L3-5 levels, participated in this study. A two-session program was conducted, and LBP, pelvic tilt angle, and trunk range of motion were measured after each se...
