The investigators plan to use a pre-test post-test research design to investigate whether dry needling (DN) has an effect on cortical excitability in patients with chronic low back pain (CLBP), specifically in patients who have developed central sensitization (CS). Therefore, the primary purpose of this study is to examine the immediate effects of a single session of DN on cortical excitability and neurosensory responses in patients CLBP. There are two specific aims: 1) to examine whether a single session of DN will change cortical excitability corresponding to the lumbar multifidus (LM) muscle, and 2) to examine whether a single session of DN will change neurosensory responses to the stimuli applied to the LM muscles.
The investigators also are interested in exploring whether DN has a differential effect on cortical excitability in patients with CLBP who have developed CS vs. those who have not developed CS. Therefore, the secondary purpose of the study is to compare the immediate effects of a single session of DN on cortical excitability between patients with CLBP who have developed central sensitization (CS) and those who do not have CS. The specific aim is to compare cortical excitability corresponding to the LM in participants with and without CS after a single session of DN.

Neck pain, neck muscle weakness, and limited neck range of motion have been shown in individuals with sinus headaches. Individuals in this previous study self-diagnosed their sinus headaches. It is unknown whether or not individuals who have been diagnosed with sinus headaches according to diagnostic criteria also present with musculoskeletal impairments.
The purpose of this study is to determine if musculoskeletal neck impairments are present in individuals diagnosed with headaches attributed to rhinosinusitis compared to people without headaches.
Upper cervical range of motion can be measured using different tests. The side bend rotation test has been suggested as potentially more useful than the flexion rotation test in individuals with hyper-laxity, however, has not been examined in a symptomatic population.
A secondary purpose is to compare the side bend rotation test to the cervical flexion rotation test in people with varying degrees of joint laxity.

Therefore, the purpose of this pilot study is to determine the feasibility of conducting a randomized clinical trial (RCT) on physical therapist treatment for dizziness after sports-related concussion. The specific research question for this pilot RCT is: What is the feasibility of conducting a RCT on athletes who have dizziness 10 or greater days after a sports-related concussion to explore the effectiveness of directed vestibular rehabilitation, neuromotor retraining, and/or manual physical therapy (PT) when compared to sham treatment? The findings of this study (for both feasibility and effect size) will be used to inform and direct revisions to the methods for a larger RCT on this population.
Primary Aims:
Specific Aim 1: Assess the feasibility of the following: recruitment and retention of participants, required resources for project management, and assessment of patient safety.
Specific Aim 2: Estimate the size of the effect between skilled physical therapist intervention and a sham treatment for the recovery rate for athletes with a concussion who have dizziness 10 - 14 days post-concussion.
