In this study two physiotherapists (PTs) at the University of Wisconsin - Madison review the records of 133 patients treated for low back disorders. There were three goals:
Patients were divided into three groups (acute, subacute, chronic) based on length of time symptoms were present. Patients were seen five to eight times each week for up to 11 weeks. Patients with chronic symptoms had more visits than patients in the acute stage.
Results of treatment were measured based on pain, function, and perceived improvement. Patients filled out a survey with questions about walking, work, personal care, sleeping, and recreation and sports.
The authors report pain decreased equally in all three groups. Patients in the chronic pain group had lower perceived recovery compared to the acute group. Function improved and disability decreased the most for patients who had symptoms for less than one month. Patients whose treatment included manual therapy (joint mobilization and/or manipulation) also had better results.
Studies of this type help physiotherapists manage patients with LBP. Knowing the best choice of treatment and best time to offer therapy services help PTs make a prognosis and improve patient results.
