Test-Retest Reliability Of The Soleus H-Reflex Is Affected By Joint Positions And Force Levels, Yungsheng Chen, Shi Zhou, Colleen Cartwright, Zachary Crowley, Robert Baglin, Fang Wang

Professor Colleen M Cartwright

The H-reflex has been extensively used to exam the spinal motoneuron excitability. However, no report has demonstrated the test-retest reliability of the H-reflex assessment during voluntary muscle contractions and its relation to joint positions. The purpose of this study was to determine the test-retest reliability of the soleus (SOL) H-reflex during rest and 10, 30, 50% maximal voluntary contractions (MVC) at the ankle joint angles of neutral (0deg), plantarflexion (20deg), and dorsiflexion (-20deg), respectively in a sitting position. Ten healthy participants (age 24.9 ± 5 years, height 168.3±8.8 cm, weight 62.7±12.3 kg) were tested for the SOL H-reflex on two …

Vestibular Influence On Cranio-Cervical Pain: A Case Report, Frank Gargano, Wayne Hing, Caroline Cross

Wayne Hing

This case report describes a 39 year old woman with a 10 month history of right-sided temporal headaches. In addition, she experienced a ‘wobble’ feeling when rolling toward her right side and reported suboccipital pain, tinnitus and a mild visual disturbance. Objective assessment revealed she had a positional upbeat clockwise torsional nystagmus, that is, a positive Dix-Hallpike test for benign paroxysmal positional vertigo. Furthermore, manual assessment revealed right upper cervical joint dysfunction. She was treated with a four stage canalith repositioning manoeuvre for the vestibular system which abolished her ‘wobble’ symptom. Subsequently, manual therapy techniques were applied to the cervical …

Clinical Predictors Of A Positive Response To Guided Diagnostic Block Into The Subacromial Bursa, Angela Cadogan, Mark Laslett, Wayne Hing, Peter Mcnair, Stephen Taylor

Wayne Hing

Objective: To compare the accuracy of combinations of clinical examination findings for predicting a positive response to injection of local anaesthetic into the subacromial bursa.

Design: Prospective, cohort, diagnostic validity design. Subjects: Consecutive patients with shoulder pain recruited from primary care physiotherapy and general medical practices.

Methods: All subjects underwent a standardised clinical examination (index test) followed by a diagnostic injection of xylocaineTM into the subacromial bursa (reference standard test) performed under ultrasound guidance. Clinical examination variables associated with a positive anaesthetic response (≥ 80% post-injection reduction in pain intensity) were identified (p

Results: Of the 196 subjects who received …

Comparison Of Longitudinal Sciatic Nerve Movement With Different Mobilization Exercises: An In Vivo Study Utilizing Ultrasound Imaging, Richard Ellis, Wayne Hing, Peter Mcnair

Wayne Hing

Study design: Controlled laboratory study using a single-group, within-subjects comparison. Objectives: To determine whether different types of neural mobilization exercises are associated with differing amounts of longitudinal sciatic nerve excursion measured in vivo at the posterior midthigh region. Background: Recent research focusing on the upper limb of healthy subjects has shown that nerve excursion differs significantly between different types of neural mobilization exercises. This has not been examined in the lower limb. It is important to initially examine the influence of neural mobilization on peripheral nerve excursion in healthy people to identify peripheral nerve excursion impairments under conditions in which …

Perceived Benefits, Motives, And Barriers To Aqua-Based Exercise Among Older Adults With And Without Osteoarthritis, Alison Fisken, Justin Keogh, Deborah L. Waters, Wayne Hing

Wayne Hing

This study aimed to (a) identify factors that motivate older adults to participate in aqua-based exercise; (b) identify potential barriers; and (c) compare perceptions between older adults with and without osteoarthritis (OA). Fifteen adults above 60 years of age participated in one of three focus groups during which they discussed perceived benefits, motives, and barriers to aqua exercise. Pain reduction was considered a major benefit among those with OA, improved health and fitness was a principal benefit for those without OA. All participants felt that the instructor could act as both a motivator and barrier; the most significant barrier was …

Comparison Of A Novel Direct Measure Of Rapid Pain Intensity Change To Traditional Serial 100 Mm Vas Measurement Of Pain Intensity, Mark Laslett, Peter Mcnair, Angela Cadogan, Wayne Hing

Wayne Hing

Objectives: Key diagnostic decisions often turn on measurement of change in pain intensity after diagnostic anesthetic blocks. This study aimed to introduce a new direct measure pain intensity change and compare it with percent change as calculated from the traditional preprocedure and postprocedure pain visual analog scales. Methods: Shoulder pain patients enrolled in a diagnostic accuracy study comparing clinical variables with image-guided local anesthetic injections were assessed with both the traditional preprocedure and postprocedure visual analog scales and the new direct method. Percent change in pain intensity was calculated with both instruments and were compared using statistical methods. The percentage …

Emg Activation Of The Vastus Medialis Oblique And Vastus Lateralis During Four Rehabilitative Exercises, Debra Kushion, Jessica Rheaume, Kim Kopchitz, Stephen Glass, Gordon Alderink, Jann-Huei Jinn

Stephen C Glass

The purpose of this study was to compare four common rehabilitation exercises used in physical therapy clinics for activating the vastus medialis oblique (VMO) and vastus lateralis (VL). Thirty-four subjects, aged 22-28 years, without patellofemoral pain syndrome (PFPS) (18 females and 16 males) were recruited. Subjects performed four exercises—straight leg raise with neutral and externally rotated hip positions (SLRN, SLRER), and short arc quad with neutral and externally rotated hip positions (SAQN, SAQER). The integrated electromyographic (iEMG) activity of the VMO and VL and were recorded, with means of the VMO, VL and VMO/VL compared across exercises. No significant difference …

Certified Professional Co-Active Coaches: Why They Enjoy Coaching, Courtney Newnham-Kanas, Don Morrow, Jennifer D. Irwin

Donald Morrow

The evidence-base for the practice of coaching continues to flourish, despite the fact that very little is known about the practitioners (i.e. the coaches) themselves. It is of value to understand how coaches perceive their practice. Such information can be utilized to create a common knowledge-base about coaches that can be used, in turn, to track trends and forward research that evaluates coaching services. As the use of Co-Active coaching in facilitating behaviour change continues to rise it becomes important to learn more about Certified-Professional Co-Active Coaches (CPCC). Therefore, the purpose of this study is to evaluate what CPCCs enjoy …
