Study Design: A randomized controlled trial. Objectives: To investigate the effectiveness of daily patella taping and exercise on pain and function in individuals with patellofemoral pain syndrome. Background: Patella taping and muscle-strengthening programs are commonly used to treat patellofemoral pain syndrome. There is, however, little evidence for the effectiveness of these approaches. Methods and Measures: Twenty-four men and 6 women aged 17 to 25 years (mean ± SD, 18.7 ± 1.2 years) participated in the study. Subjects were randomly and exclusively assigned to 1 of 3 treatment groups: patella taping combined with a standardized exercise program, placebo patella taping and exercise program, or exercise program alone (n = 10 in each group). Taping was applied and exercises performed on a daily basis for 4 weeks. Outcome measures were visual analog scales for pain and the functional index questionnaire, recorded at weekly intervals by a therapist who was blinded to group allocation. Results: Separate mixed-model ANOVAs, with repeated measures on time, indicated statistically significant improvements in pain and function over time for all groups (P <.01) and also significant differences between groups for all measures (P <.01). Separate independent samples t tests showed that the group receiving taping and exercises had better pain and function scores following treatment than the placebo taping-and-exercise group and the exercise-alone group. There were no significant differences between the placebo taping-and-exercise group and exercise-alone group at any time point. Conclusions: These findings indicate that over a period of 4 weeks a combination of daily patella taping and exercises was successful in improving pain and function in individuals with patellofemoral pain syndrome. The combination of patella taping and exercise was superior to the use of exercise alone.

Study Design: Clinical case report. Objectives: To describe a physical therapy program addressing impairments of the upper thoracic and cervical spine region for an individual with a whiplash-associated disorder. Background: A 32-year-old female with complaint of diffuse posterior cervical and upper thoracic region pain was evaluated 2 weeks following a motor vehicle accident. The patient reported that she was unable to sit for longer than 10 minutes or perform household duties for longer than 1 hour. In addition, she was unable to perform her tasks as a postal worker or participate in her customary running and aerobic exercise activities because of pain in the cervical and upper thoracic region. Methods and Measures: An examination for physical impairments was performed, including the measurement of cervical range of motion using the CROM device, and the assessment of soft tissue and segmental mobility of the upper thoracic and cervical spine regions. The Northwick Park Neck Pain Questionnaire was used to assess functional limitations and disability. Manual therapy and therapeutic exercises were applied to address the identified impairments. Manual therapy techniques included soft tissue mobilization, joint mobilization, and joint manipulation. Results: The patient’s cervical range of motion was improved and the disability score improved from 25% to 19.5% 3 days after the initial session addressing the thoracic spine. Following a second session also addressing thoracic spine impairments and the use of therapeutic exercises for 7 days, the disability score improved to 11.1%. At the final visit 17 days following the third visit, which focused on addressing the cervical spine impairments, there was complete resolution of signs and symptoms and disability. Conclusions: Interventions addressing the impairments of the upper thoracic and cervical spine region were associated with reducing pain, increasing cervical range of motion, and facilitating return to work and physical activities in a patient with a whiplash-associated disorder. There is a need for continued research investigating the efficacy of providing interventions to the thoracic spine for patients with whiplash-related injuries.

Study Design: Cross-sectional. Objectives: To test the assumption that postural alignment and gender have a bearing on the specific type of low back pain (LBP) a person manifests. Background: Measurements of static sagittal lumbar curvature are used by clinicians in the management of patients with LBP, but no investigator has reported differences in curvature related to specific categories of LBP. Methods and Measures: We used a computer-interfaced, 3-D, electromechanical digitizer to derive curvature angles for the region of the spine between T12-L1 and S2. Trained clinicians examined the subjects and determined their LBP diagnoses. We used t tests to examine differences in curvature between women and men, those with and those without LBP, and those in 4 different categories of LBP. We used x2 to examine the relationship between gender and LBP category. Results: Lumbar curvature angle (lordosis) was 13.2° larger for women than for men (t = 6.74; P<.01). There was no difference in lumbar curvature between people with undifferentiated LBP and people without LBP. There were differences in lumbar curvature between people in various categories of LBP, for example, subjects in the lumbar-rotation-with-extension category had 8.4° more lumbar curvature than subjects in the lumbar-rotation-with-flexion category (t = 2.16; P<.05). Based on the frequency distributions, there was a significant relationship between gender and LBP category (x2 = 10.19; P<.01). Conclusions: Measurements of lumbar curvature should be expected to differ between men and women and may be related to different types of low back pain.

Study Design: Single-case A1-B-A2 design. Objective: To determine if manual physical therapy, therapeutic exercise, and patient education would be an effective management strategy for a patient with a disc displacement without reduction of both temporomandibular joints. Background: A number of conservative management strategies have been proposed for the treatment of temporomandibular disorders. However, little evidence exists to indicate the effectiveness of physical therapy interventions in patients with bilateral disc displacement without reduction. Methods and Measures: Phase A1 of the study consisted of a baseline condition in which no intervention was initiated. Phase B included manual physical therapy, therapeutic exercise, and patient education focusing on the temporomandibular joint and cervical spine. Phase A2 consisted of withdrawal of the intervention. The Steigerwald/Maher disability questionnaire was used to collect data relative to function. A visual analog scale was used to collect pain data and maximal mouth opening measurements were obtained as an indicator of range of motion. Visual analysis and the 2 standard deviation band method of statistical analysis were used to compare data. Results: Following the implementation of the intervention phase, the patient demonstrated significant reductions in pain and improvements in maximal mouth opening and function as measured by the Steigerwald/Maher disability questionnaire. These observed improvements were maintained at the time of a 3-month follow-up. Conclusions: The results of our study suggest that manual physical therapy, therapeutic exercise, and patient education may have been an effective management strategy for a patient with bilateral disc displacement without reduction of the temporomandibular joints. Further outcome studies in the form of randomized controlled trials are needed to determine the clinical utility of this treatment approach in a larger population.

Study Design: Prospective, randomized, crossover design. Objectives: To compare the effectiveness of the Johnson & Johnson Back Plaster, the ABC Warme-Pflaster, and the ThermaCare HeatWrap on skin and paraspinal muscle temperature. Also, to compare the subjects’ heat perception for the 3 products. Background: Heat therapy is a common treatment for low back pain and disability. There are a number of products on the market that are suggested to relieve low back pain by providing warmth to the back; however, their effectiveness for increasing tissue temperature compared with heat sensation has not been tested. Methods and Measures: To measure paraspinal muscle temperature, 1 thermocouple monofilament was inserted into the paraspinal muscle 2 cm from the skin surface at the L3 level using a 20-gauge 1.25-in (3.15-cm) sterile catheter. To measure skin interface temperature, 2 thermocouples were placed on the skin at distances of 5 cm and 7 cm from the insertion site. The Isothermex was used to record temperatures to the nearest 0.1°C for 120 minutes. The subjects also rated heat perception using a 10-cm visual analog scale at 0, 30, 60, 90, and 120 minutes. Analysis of covariance models was used for statistical analysis. Results: There was a significant product × time interaction (F14,231 = 3.77, P<.0001) at the intramuscular site, but there was not a significant product × time interaction (F14,231 = 1.03, P = .4228) at the skin site. Both the main effects for product (F2,33 = 41.59, P<.0001) and time (F3,51 = 19.02, P<.0001) were significant for the visual analog scale data. The ThermaCare HeatWrap produced significant increases in both skin and intramuscular temperatures with less heat sensation. The Johnson & Johnson Back Plaster and the ABC Warme-Pflaster increased temperature at the skin surface and provided the greatest heat sensations, but they did not provide intramuscular heat. Conclusions: The ThermaCare HeatWrap is more effective at increasing temperature at a 2-cm depth with less perceived heat compared to the Johnson & Johnson Back Plaster and the ABC Warme-Pflaster. The latter 2 products provide a sensation of heat but do not actually provide a muscle temperature change at a depth of 2 cm.

This was the second Foot and Ankle Research Retreat sponsored by the Foot and Ankle Interest Group of the Orthopedic Section of the American Physical Therapy Association. It was hosted by the Department of Biokinesiology and Physical Therapy at the University of Southern California and was held April 30 to May 1, 2004. The purpose of this second retreat was to address the measurement of foot motion, focusing on the various foot models that have recently been proposed in the scientific community. Clinicians and scientists with a common interest in the measurement of foot and ankle mechanics attended the retreat. The 40-plus participants included registrants from across the United States as well as Australia, Singapore, and England. A scientific call for abstracts for the retreat was announced in the summer of 2003. All abstracts were then peer reviewed for scientific merit and relevance to the retreat. In the end, 14 abstracts were accepted for podium presentations. These were grouped into sessions addressing multisegment foot models, hindfoot modeling, and new techniques and applications. The format of the 2-day meeting included 1 keynote presentation each day, along with 20-minute podium presentations made by some of the participants. Thirty-minute discussions followed each session and each keynote address. The keynote presenters were chosen for their scientific contributions in the area of measuring foot and ankle motion. Arne Lundberg, MD, PhD, from the Karolinska Institute in Stockholm, Sweden gave the first keynote. Dr. Lundberg is a pioneer in the area of measuring multisegment foot motion, and his address was titled ‘‘The Ankle/Foot Complex: Solid Block, Gearbox or Cushion?’’ The second keynote presenter was Neil Sharkey, PhD, from The Pennsylvania State University. Dr. Sharkey developed one of the first gait simulators, and he presented his research in a keynote titled ‘‘One Step at a Time: Lessons Learned from Cadaver Simulation of Locomotion.’’ In this special report, you will find a consensus statement, a listing of the presentations and authors, and an abstract of each of the presentations made at the conference.
