STUDY DESIGN A prospective methodological study of interrater reliability. OBJECTIVES To examine the interrater reliability of a movement impairment-based classification system for patients with chronic low back pain (LBP). BACKGROUND Movement impairment-based classification for the lumbar spine categorizes LBP based on the findings derived from a(More)
OBJECTIVE(S) (1) To compare the effectiveness of customized exercises with that of standard exercises for the treatment of patients with shoulder disorders. (2) To determine whether four weeks or eight weeks would be needed to see improvement in outcome measures. DESIGN A single-blinded randomized clinical trial. SETTING An outpatient physical therapy(More)
Muscle tightness is often considered to be a predisposing factor in muscle injuries. The purpose of this study was to assess the muscle flexibility of the hamstrings, rectus femoris, iliopsoas, gastrocnemius, and soleus muscles in long distance runners. Range of motion measurements of five movements, including hip flexion with knee extended, hip extension(More)
Overselective stimulus control was assessed in 29 students at residential schools for individuals with developmental disabilities. Overselectivity testing included three different delayed identity matching-to-sample tasks. Sample stimuli for the Form/Color Test were nine possible combinations of three colors and three forms. On each trial, the S+ stimulus(More)
Phenytoin (sodium salt), a developmental neurotoxicant, was administered orally by gavage (50-150 mg/kg) to pregnant rats on days 7-18 of gestation. Various developmental and behavioral indices were evaluated. Results indicated that phenytoin produced decreases in maternal and pup body weight gains, pup hindbrain, and F1 adult forebrain, whole brain, and(More)
OBJECTIVE Clinical evidence has shown that extremity dysfunction, such as muscle weakness or inhibition, is associated with spinal disorders. Spinal manual therapy is a common therapeutic approach used to address extremity muscle weakness. The purpose of the study was to assess changes in the maximal muscle strength of the shoulder external rotators(More)
A delayed matching-to-sample task with multiple sample stimuli was used to evaluate stimulus overselectivity in 70 individuals attending residential special-education schools. A Mental Age Equivalent score (MAE) was obtained for each student using the Peabody Picture Vocabulary Test. Twenty-one participants failed to complete matching-to-sample pretests(More)
The purposes of this study were to determine inter-tester reliability, one-week test-retest reliability and smallest detectable difference (SDD) of serratus anterior muscle strength and endurance tests. Asymptomatic subjects were tested on an apparatus designed by the investigators. During strength testing, subjects performed isometric contractions recorded(More)
BACKGROUND Neuromuscular electrical stimulation initiated by a surface electromyographic biofeedback threshold (sEMG-triggered NMES) has been studied in populations of patients with neurological problems, but has not been applied to orthopedic populations. OBJECTIVES The purpose of this single-blinded, randomized clinical trial was to investigate(More)
PURPOSE To compare changes in supraspinatus muscle thickness in persons with subacromial impingement syndrome (SAIS) and asymptomatic adults and to determine the reliability of the ultrasound imaging (USI) protocol. SUBJECTS Twenty-two persons with SAIS and 22 age- and gender-matched asymptomatic controls. METHODS Ultrasound images of supraspinatus(More)
