[Purpose] The purposes of this study were: 1) describe a hierarchy of electromyographic activity production, using percentage maximum voluntary contraction of lumbar iliocostalis and lumbar multifidus muscles during prone, quadruped and sitting exercises; and 2) identify optimal recruitment exercises for both lumbar iliocostalis as a global multi-segmental stabilizer and lumbar multifidus as a ...

INTRODUCTION The peak knee adduction moment (PKAM) is a gait measure which best represents the mechanical pathology associated with knee osteoarthritis (OA). Recent research has focused on whether the PKAM is modified by muscle function. While knee strengthening exercises reduce pain and improve quality of life, strengthening has little effect on the PKAM in OA [1]. Lower-limb muscle power is m...

Although hip muscle strengthening has been reported as an effective way to decrease PFPS symptoms, however its effect on lower extremity kinematics is less clear. The current study was done with the aim of investigating the effect of hip abductor and external rotator muscles strengthening exercises on lower extremity kinematics in static and dynamic states. In a randomized controlled trial, 33 ...

Severe, persistent back pain following back surgery is often referred to as Failed Back Surgery Syndrome (FBSS). Conservative measures such as physiotherapy, back strengthening exercises, transcutaneous electrical nerve stimulation and epidural steroids may be inadequate to alleviate pain. Spinal Cord Stimulators were implanted into two patients suffering from FBSS. Both patients responded succ...

A prospective study was conducted to clarify the 1-year changes in lumbar spine and hip bone mineral density (BMD) and bone turnover markers in premenopausal amateur runners and to determine whether jumping and muscle-strengthening exercises have additive effects on the bone parameters in these runners. Thirty-six premenopausal amateur runners were recruited and were divided into the following ...

Exercise is recognized as one of the optimal managements for chronic low back pain. Among the numerous therapeutic exercises, the approaches of traditional strengthening exercise and segmental stabilization exercise are considerably different. The purpose of this study was to compare the effectiveness of the two different exercise approaches, on chronic low back pain through evaluating previous...

[Purpose] We explored the effect of thoracic movement-mediated training (TMMT) on back pain and trunk range of motion (ROM) in a lower back pain (LBP) patient with lumbar flexion rotation syndrome. [Subject] A 55-year-old male LBP patient with lumbar flexion rotation syndrome. [Methods] The subject underwent TMMT, consisting of two thoracic stretching exercises and three thoracic muscle-strengt...

Core strengthening and stability exercises have become key components of training programs for athletes of all levels. The core muscles act as a bridge between upper and lower limbs, and force is transferred from the core, often called the powerhouse, to the limbs. Stability initially requires maintenance of a neutral spine but must progress beyond the neutral zone in a controlled manner. Some ...

[Purpose] To evaluate treatments with interferential current, hot pack, ultrasound therapy, stretching, strengthening and range-of-motion exercises, comparing between the right and left shoulders in terms of pain and functional capacity in patients with frozen shoulder. This was a retrospective study. [Subjects and Methods] Sixty-four patients (34 right side, 30 left side) were treated with int...

BACKGROUND Strengthening of core hip, trunk, and abdominal muscles has been utilized with injury prevention and low back pain and has the potential to improve athletic performance. HYPOTHESIS During a side-bridge, trunk and thigh muscles on the ipsilateral weightbearing side would produce greater activation than their counterparts on the contralateral nonweightbearing side. STUDY DESIGN Des...
