5 key points on reposition accuracy in patients with unspecific low back pain

A new study published in Spine examines lumbar reposition error in patients with nonspecific chronic low back pain.

The researchers examined 178 records to review reposition error for patients with nonspecific chronic low back pain compared against controls. There were 13 records with the appropriate inclusion criteria. The researchers found:


1. In most studies, the patients with nonspecific chronic low back pain had larger absolute error and variable error when compared with the controls.


2. Constant error was direction-specific in flexion and active extension in the pattern subgroups of patients with nonspecific chronic low back pain.


3. The reporting quality and risk of biased varied considerably between the articles. The applied test procedures and instrumentation also varied between studies, making them difficult to compare.


4. The authors recommend future studies on nonspecific chronic low back pain pay closer attention to power, precision and measurement approach reliability. They also emphasized defining outcomes measures and patient selection.


5. This issue also needs a large, prospective randomized control study that uses a standardized measurement approach to address a hypothesis that proprioception could be impaired with chronic low back pain.
