Thorough Research Questions should have Layers
By: Chad E Cook PT, PhD, FAPTA Order Questions Most of our musculoskeletal treatments fall within a ‘gray zone’ of effectiveness1. Nearly none of our treatments are strongly effective all of the time and few have no benefit all of the time. This is one of the reasons we see outcomes that are consistently similar […]
The Hip Barely Moves During Joint Mobilization: What does that mean for clinicians?
Seth Peterson, PT, DPT, OCS, FAAOMPT In a popular video, a clinician demonstrates the vacuum phenomenon of the hip joint in a cadaver, moving the femoral head around to create suction and then pulling (clearly very hard) to demonstrate how strong that suction force can be. It prompts the question – if someone can apply […]
The Truth? Whose Truth?
By: Chad E Cook PT, PhD, FAPTA; Sean P. Riley, PT, DPT, ScD The Truth? Whose Truth? Our impetus for writing this blog is our disappointment with modern United States news media outlets, how they report information, and how it impacts the public. Their extremist style of reporting has led to a division of thought […]

Mechanisms are Not Clinical Outcomes but Both Are Very Important
By: Chad E Cook PT, PhD, FAPTA What are Mechanisms? The term “mechanism” reflects the theoretical steps or processes through which an intervention (or some independent variable) unfolds and produces a change in a patient. For example, a cortisone injection for a frozen shoulder works by stopping the release of regional molecules that cause inflammation […]
Null statistical hypothesis testing, confirmation bias, and statistical significance
By: Sean P. Riley, PT, DPT, ScD Null statistical hypothesis testing aims to prevent confirmation bias [1]. The researcher creates the null hypothesis by converting the research question to a research hypothesis and then converting the research hypothesis to the null hypothesis. This should happen before starting data collection starts. The researcher should use statistical […]
Sham Manual Therapy: An Oxymoronic Approach
By: Chad E Cook PT, PhD, FAPTA Overview In this blog, I hope to show that there is no proper way to perform a sham orthopaedic manual therapy (OMT) study in a way that unambiguously allows a comparison between an intervention and therapeutic intent. The idea is good. The execution is likely not possible.
Manual Therapy Myths
By: Chad E Cook PT, PhD, FAPTA Myths and health Accordingly to the Oxford dictionary, a myth is a widely held but false belief (or idea). We commonly encounter health-related myths in our daily lives. For example, despite what you may have heard, cracking ones knuckles does not cause arthritis. Coffee doesn’t stunt the growth […]
