About

Emergency department (ED)-initiated physical therapy is a rapidly growing resource and represents a promising treatment approach to low back pain. This clinical trial will evaluate an innovative model of an emergency department "embedded" physical therapist to treat patients with chronic low back pain, with a focus on improving patient functioning and reducing opioid use.

Full description

This trial is ancillary to an ongoing single-center physician-randomized trial of an embedded physical therapy intervention versus usual care in ED patients with acute low back pain (NEED-PT, NCT04921449), comparing a primary outcome of pain-related functioning and a secondary outcome of opioid use at three months. The main trial aims to enroll up to 360 participants with acute low back pain, defined as ≤ 30 days in duration and no history of lumber surgery or chronic low back pain. Using the same procedures and physician-randomization assignments as the main trial, this ancillary trial will enroll an additional 200 participants with chronic low back pain (i.e. non-acute low back pain) in order to obtain initial point estimates for the outcomes of interest and assess participant enrollment and retention rates in this population. The ancillary trial's sample size of 200 participants is an estimate of patient accrual over the anticipated remaining duration of the main trial (i.e., there is not a separate power calculation for this ancillary trial given its exploratory nature), and the actual number accrued may differ depending on the main trial's actual end date.

Embedded ED Physical Therapy

Experimental group

Description:

An ED physical therapist will be embedded with the primary treatment team to evaluate patients presenting with low back pain at the beginning of the overall treatment course. The physical therapist will utilize a clinical protocol that matches the patient's history and exam findings to an appropriate treatment classification consisting of directional preference exercises, manual traction, stabilization exercises, non-thrust manipulation/mobilization, and/or psychologically informed rehabilitation. The embedded PT intervention will supplement any usual care performed by the treating physician.

Treatment:

Other: ED Physical Therapy

Usual Care

No Intervention group

Description:

Usual care consists of any ED testing or treatment not involving an ED physical therapist in accordance with the treating physician's usual and customary practice. This could include diagnostic imaging, patient education and reassurance, and administration and/or prescribing of analgesic medications.
