Recovery of the Japanese orthopedic association back pain evaluation questionnaire score and walking ability following lumbar spinal stenosis surgery.

Purpose: We investigated the recovery of the Japanese orthopedic association back pain evaluation questionnaire (JOABPEQ) scores and 6 min walk distance (6MWD) in patients after surgery for lumbar spinal stenosis and identified the items among 25 questions of JOABPEQ that showed recovery.

Methods: A total of 227 patients (average age 71.5 years; SD: 7.

Minimal Clinically Important Difference of the 6-Minute Walk Distance in Patients Undergoing Lumbar Spinal Canal Stenosis Surgery: 12 Months Follow-Up.

Study Design: Retrospective review of prospectively collected data.

Objective: We evaluated the responsiveness of the 6-minute walk distance (6MWD) and determined the threshold of the minimal clinically important difference (MCID) in patients who underwent lumbar spinal stenosis (LSS) surgery.

Summary Of Background Data: Little evidence exists on the MCID of 6MWD after LSS surgery.

Relationship between changes in physical function parameters and Roland-Morris disability questionnaire score after decompression surgery for lumbar spinal canal stenosis.

Although decompression surgery for lumbar spinal canal stenosis (LSS) improves leg symptoms, low back pain (LBP), and disability, the factors related to the improvement of subjective disability have not been studied sufficiently. The purpose of the study was to clarify the relationship between subjective disability and objective physical function parameters. A total of 51 patients who underwent decompression were included and evaluated preoperatively and 6 and 12 months postoperatively.

Reliability and validity of lower limb joint range of motion measurements using a smartphone.

This study aimed to examine the reliability and validity of using a smartphone to measure the multi-joint range of motion of the lower limbs. We measured the straight leg raise angle, ankle dorsiflexion angle, and hip internal rotation angle in each of the 40 lower extremities of 20 healthy adults. Measurements were compared between a conventional method using a goniometer and a smartphone application method.

Responsiveness and Minimal Clinically Important Difference of the 6-minute Walk Distance in Patients Undergoing Lumbar Spinal Canal Stenosis Surgery.

Study Design: This was a retrospective review of prospectively collected data.

Objective: We aimed to evaluate the responsiveness of the 6-minute walk distance (6MWD) and determine the threshold of the minimal clinically important difference (MCID) in the 6MWD in patients who underwent surgery for lumbar spinal canal stenosis (LSS) surgery.

Summary Of Background Data: The 6MWD rapidly and objectively assesses the walking distance in patients with LSS.

Predictors of walking ability after surgery for lumbar spinal canal stenosis: a prospective study.

Background Context: Few studies have investigated predictors of objective walking distance in patients with lumbar spinal stenosis (LSS).

Purpose: This study aimed to clarify objective predictors of postoperative 6-minute walk distance (6MWD) in patients with LSS and to develop prediction equations.

Study Design: This was a prospective study.

A Compaction Bone Grafting Technique Leads to Early Bone Fusion in Cases of Posterior Lumbar Interbody Fusion.

Background: The impaction bone grafting technique is a popular approach for achieving complete bone fusion during hip surgery or total knee arthroplasty. We hypothesized that compaction bone grafting (CBG), a modified version of impaction bone grafting, could be applied to lumbar fusion surgery.

Objective: To compare the bone fusion rates and durations achieved using the CBG technique and a conventional loose bone grafting technique.
