This article reviews 6 selected cases of improvement/resolution of chronic back pain or failed back surgery after vitamin D repletion in a Canadian family practice setting. Pub Med was searched for articles on chronic back pain, failed back surgery, and vitamin D deficiency. Chronic low back pain and failed back surgery may improve with repletion of vitamin D from a state of deficiency/insuffic...

BACKGROUND The impairment in musculoskeletal structures in patients with low back pain (LBP) is often disproportionate to their complaint. Therefore, the need arises for exploration of alternative mechanisms contributing to the origin and maintenance of non-specific LBP. The recent focus has been on central nervous system phenomena in LBP and the pathophysiological mechanisms underlying the var...

The d-ary back-to-back tree of height k, BBT k d , consists of two complete d-ary trees of height k the leaves of which are identiied. For a proper coloring of the edges of BBT k d with c d + 1 colors, we consider periodic gossiping, i.e. full-duplex all-to-all broadcasting in the 1-port model where communication is made on a link of color i at any time (round) i mod c. We present a coloring fo...

INTRODUCTION Patients with chronic low back pain (CLBP) often demonstrate altered timing of thorax rotations in the transverse plane during gait. Increased axial trunk stiffness has been claimed to cause this movement pattern. OBJECTIVES The objective of this study was to assess whether axial trunk stiffness is increased in gait in CLBP patients. METHODS 15 CLBP patients and 15 healthy cont...

UNLABELLED Chronic low back pain (CLBP) is the leading cause of absenteeism from the workplace and research into exercise interventions to address this problem is required. This study investigated training frequency for participants with CLBP. Participants either trained once a week (1 × week, n = 31), or twice a week (2 × week, n = 20) or did not (control group, n = 21). Participants were isom...

STUDY DESIGN A multicenter, randomized, controlled trial with 1-year follow-up. OBJECTIVES To compare the effect of manual therapy to exercise therapy in sick-listed patients with chronic low back pain (>8 wks). SUMMARY AND BACKGROUND DATA The effect of exercise therapy and manual therapy on chronic low back pain with respect to pain, function, and sick leave have been investigated in a num...

OBJECTIVE To estimate worldwide prevalence of chronic low back pain according to age and sex. METHODS We consulted Medline (PubMed), LILACS and EMBASE electronic databases. The search strategy used the following descriptors and combinations: back pain, prevalence, musculoskeletal diseases, chronic musculoskeletal pain, rheumatic, low back pain, musculoskeletal disorders and chronic low back p...

[Purpose] To investigate whether pain, balance, and stabilization of the lumbar region can be improved through thoracic mobilization in addition to lumbar stabilizaing exercises. [Subjects and Methods] This study recruited 36 subjects with chronic low back pain lasting more than 12 weeks. The subjects recruited for this study participated voluntarily, and provided their signed consent to partic...

BACKGROUND Chronic low back pain (CLBP) is often accompanied by an abnormal motor performance. However, it has not been clarified yet whether these deviations also occur during motor tasks not involving the back and whether the performance is influenced by pain and pain-related cognitions. Therefore, the aim of the present study is to get insight in the contribution of both pain experience and ...

INTRODUCTION Chronic lower back pain (CLBP) is a major healthcare problem with wide ranging effects. It is a priority for appropriate management of CLBP to get individuals back to work as early as possible. Interventions that identify biopsychosocial barriers to recovery have been observed to lead to successfully reduced pain-related work absences and increased return to work for individuals wi...
