Shoulder impingement syndrome (SIS) is a complex, multi-factorial problem that is treated with a variety of different conservative options. One conservative option that has shown effectiveness is manual therapy to the thoracic spine. Another option, manual therapy to the cervical spine, has been studied only once with good results, evaluating short-term(More)
BACKGROUND Recovery from low back pain (LBP) is multidimensional and requires the use of multiple-response (outcome) measures to fully reflect these many dimensions. Predictive prognostic variables that are present or stable in all or most predictive models that use different outcome measures could be considered "universal" prognostic variables. OBJECTIVE(More)
Many musculoskeletal management philosophies advocate the exploration of the relationship between the patient's chief complaint (CC) and the physical examination findings that reproduce/reduce/change that CC. Geoffrey Maitland developed the concept "comparable sign(s) (CS), which are physical examination findings related to the CC(s) that are reproduced(More)
BACKGROUND Minimal clinically important difference (MCID) scores for outcome measures are frequently used evidence-based guides to gage meaningful changes. There are numerous outcome instruments used for analyzing pain, disability, and dysfunction of the low back; perhaps the most common of these is the Oswestry disability index (ODI). A single agreed-upon(More)
The purposes of the study were to determine whether the combined occurrence of within/between-session changes were significantly associated with functional outcomes, pain, and self-report of recovery in patients at discharge who were treated with manual therapy for low back pain. A secondary purpose was to determine the extent of change needed for the(More)
OBJECTIVES Neck pain is routinely managed using manual therapy (MT) to the cervical and thoracic spines. While both mobilizations and manipulations to these areas have been shown to reduce neck pain, increase cervical range of motion, and reduce disability, the most effective option remains elusive. The purpose of this preliminary trial was to compare the(More)
BACKGROUND AND PURPOSE The aim of this study was to identify the minimal clinically important threshold score for rate of recovery (RoR) using the Patient Acceptable Symptom State (PASS) as an anchor measure, and to measure the association of the RoR with the raw and percentage change scores of the QuickDASH and the Numeric Pain Rating Scale (NPRS).

The purpose of this study was to investigate the comparative effectiveness of early use of thrust (TM) and non-thrust manipulation (NTM) in sample of patients with mechanical low back pain (LBP). The randomized controlled trial included patients with mechanically reproducible LBP, ≥ age 18-years who were randomized into two treatment groups. The main(More)
