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.

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.

Validation of the Risk Score of the Mortality and Lower Limb Loss Considering Ambulatory Status after Surgical Revascularization in Maintaining Patients with Dialysis.

Surgical revascularization is performed to preserve limb and to maintain functional status of patients with critical limb ischemia (CLI). The PREVENT III risk score helps to predict the postoperative course of CLI. However, this score is not available to estimate the risk of amputation or death properly in patients with hemodialysis (HD) and tissue loss (HD: 4 points, Tissue loss: 3 points), because they are classified as a high-risk group.

Validity of submaximal exercise testing in adults with athetospastic cerebral palsy.

Objective: To examine the validity of the multistage submaximal cycle ergometer test for adults with athetospastic cerebral palsy.

Design: Cross-sectional and correlative study. Oxygen uptake and heart rates were recorded while the participants underwent the maximal cycle ergometer test and the multistage submaximal cycle ergometer test.

Is latero-medial patellar mobility related to the range of motion of the knee joint after total knee arthroplasty?

Diminished range of motion (ROM) of the knee joint after total knee arthroplasty (TKA) is thought to be related to reduced patellar mobility. This has not been confirmed clinically due to a lack of quantitative methods adequate for measuring patellar mobility. We investigated the relationship between patellar mobility by a reported quantitative method and knee joint ROM after TKA.

Relation of falls efficacy scale (FES) to quality of life among nursing home female residents with comparatively intact cognitive function in Japan.

The purpose of this study was to investigate the relation of the Falls Efficacy Scale (FES) to quality of life (QOL) among nursing home residents. The subjects were 133 institutionalized women aged 70 years or older. They had comparatively intact cognitive function, with a Mini-Mental State Examination (MMSE) score of 15 or more, and could provide sufficient informed consent for a questionnaire survey.

Comparison of patellar mobility in female adults with and without patellofemoral pain.

Study Design: Case control study.

Objective: To compare the patellar mobility of female adult subjects with and without patellofemoral pain (PFP).

Background: Although abnormal patellar mobility is believed to be one of the causes of PFP, there is currently no published evidence to support this contention.

Relationship between maximum shoulder external rotation angle during throwing and physical variables.

The amount of stress imposed on shoulder and elbow appears to be directly correlated with the degree of maximum shoulder external rotation (MER) during throwing motions. Therefore, identifying risk factors contributing to the increase of MER angle may help to decrease the throwing injuries occurrence in baseball players. The purpose of the present study was to demonstrate the correlation between MER and the kinematic variables at stride foot contact (SFC) during the early cocking phase, the passive range of motion (ROM), and the shoulder strength.

The role of shoulder maximum external rotation during throwing for elbow injury prevention in baseball players.

The objective of the present study was to examine whether the passive range of shoulder external rotation (ER), the maximum shoulder external rotation angle (MER) during throwing, and the ratio of MER to ER are related to the incidence of the elbow injury. A mixed design with one between-factor (a history of the elbow injury) and two within-factors (ER and MER) was used to analyze the difference between baseball players with and without a history of medial elbow pain. Twenty high school baseball players who had experienced the medial elbow pain within the previous month but who were not experiencing the pain on the day of the experiment were recruited (elbow-injured group).
