Participant Flow

We recruited 50 patients with chronic low back pain through media advertising in a midwestern suburban area.

143 people were screened by phone, eligible patients (58) attended a baseline visit. Subjects were eligible if they were 18+ years of age and symptomatic with pain between T12-S1 joints with or without radiating pain for at least 3 months. Patients were randomized to a treatment group receiving custom-made orthotics or a wait-list control group.

Measure
Orthotic Group
This group received orthotics at randomization visit. Various outcome measures were collected over 12 weeks.
Wait Group
This group received NO orthotics at the randomization group, as they were randomized to the wait-control group. Orthotics were given to these subjects at week 6. Various outcome measures were collected during the 12 weeks.

PRIMARY outcome

Timeframe: Randomization, Week 6, and Week 12

Population: Three participants were lost to follow-up in the Orthotic group and one was lost to follow-up in the Wait group, resulting in a drop from 25 participants in each group to 22 and 24 respectively.

This scale measures pain on a scale of 0 (no pain) to 10 (worst pain imaginable). A higher score on this scale indicates a worse outcome or increase in pain.

PRIMARY outcome

Timeframe: Randomization, Week 6, and Week 12

Population: Three participants were lost to follow-up in the Orthotic group and one was lost to follow-up in the Wait group, resulting in a drop from 25 participants in each group to 22 and 24 respectively.

This index measures the functional disability of the subject, points on this index can range from 0-50. A higher numeric value on this scale indicates a worse outcome or increased disability (e.g. 0-10: minimal disability; 11-20: moderate disability; 21-30: severe disability; 31-50: crippling). Absolute scores are reported in the data table.
