STUDY DESIGN: Prospective, randomized, double-blinded, clinical trial using a repeated-measures design. OBJECTIVES: To determine the short-term clinical efficacy of Kinesio Tape (KT) when applied to college students with shoulder pain, as compared to a sham tape application. BACKGROUND: Tape is commonly used as an adjunct for treatment and prevention of musculoskeletal injuries. A majority of tape applications that are reported in the literature involve nonstretch tape. The KT method has gained significant popularity in recent years, but there is a paucity of evidence on its use. METHODS AND MEASURES: Forty-two subjects clinically diagnosed with rotator cuff tendonitis/impingement were randomly assigned to 1 of 2 groups: therapeutic KT group or sham KT group. Subjects wore the tape for 2 consecutive 3-day intervals. Self-reported pain and disability and pain-free active ranges of motion (ROM) were measured at multiple intervals to assess for differences between groups. RESULTS: The therapeutic KT group showed immediate improvement in pain-free shoulder abduction (mean ± SD increase, 16.9° ± 23.2°; P = .005) after tape application. No other differences between groups regarding ROM, pain, or disability scores at any time interval were found. CONCLUSION: KT may be of some assistance to clinicians in improving pain-free active ROM immediately after tape application for patients with shoulder pain. Utilization of KT for decreasing pain intensity or disability for young patients with suspected shoulder tendonitis/impingement is not supported. LEVEL OF EVIDENCE: Therapy, level 1b-.

STUDY DESIGN: Case control study. OBJECTIVE: To compare the patellar mobility of female adult subjects with and without patellofemoral pain (PFP). BACKGROUND: Although abnormal patellar mobility is believed to be one of the causes of PFP, there is currently no published evidence to support this contention. In part, this lack of evidence is because a reliable clinical measurement method to measure patellar mobility and objective criteria to define abnormal patellar mobility have not been established. METHODS AND MEASURES: The study sample was comprised of 22 females with PFP (PFP group) and 22 females who had no knee pain (control group), matched by age, height, and body mass index to the subjects with PFP. Patellar mobility was measured objectively using a specially designed apparatus. Measurements of lateral and medial patellar displacement, patellar mobility balance (lateral minus medial patellar displacement), lateral patellar mobility index (lateral patellar displacement divided by patellar width), and medial patellar mobility index (medial patellar displacement divided by patellar width) were used. RESULTS: Lateral and medial patellar mobility values were not significantly different between the individuals in the PFP and control groups. When normal patellar mobility was arbitrarily defined as the average mobility ± 2 SDs, based on the data from the control group, normal lateral patellar displacement was within a range of 7.2 to 17.6 mm and normal medial patellar displacement was within a range of 6.8 to 14.0 mm. The intraclass correlation coefficient for intratester and intertester reliability of lateral and medial patellar displacement measurements varied from 0.80 to 0.97. CONCLUSION: Although there were no significant differences in patellar mobility between females with and without PFP, these measurements give reference information about normal patellar mobility for this group. LEVEL OF EVIDENCE: Diagnosis, level 5.

STUDY DESIGN: Experimental laboratory study. OBJECTIVES: To examine how a change in trunk position influences the kinematics, kinetics, and muscle activity of the lead lower extremity during the forward lunge exercise. BACKGROUND: Altering the position of the trunk during the forward lunge exercise is thought to affect the muscular actions of the lead lower extremity. However, no studies have compared the biomechanical differences between the traditional forward lunge and its variations. METHODS AND MEASURES: Ten healthy adults (5 males, 5 females; mean age ± SD, 26.7 ± 3.2 years) participated. Lower extremity kinematics, kinetics, and surface electromyographic (EMG) data were obtained while subjects performed 3 lunge exercises: normal lunge with the trunk erect (NL), lunge with the trunk forward (LTF), and lunge with trunk extension (LTE). A 1-way analysis of variance with repeated measures was used to compare lower extremity kinematics, joint impulse (area under the moment-time curve), and normalized EMG (highest 1-second window of activity for selected lower extremity muscles) among the 3 lunge conditions. RESULTS: During the LTF condition, significant increases were noted in peak hip flexion angle, hip extensor and ankle plantar flexor impulse, as well as gluteus maximus and biceps femoris EMG (P<.015) when compared to the NL condition. During the LTE condition, a significant increase was noted in peak ankle dorsiflexion and a significant decrease was noted in peak hip flexion angle (P<.015) compared to the NL condition. CONCLUSIONS: Performing a lunge with the trunk forward increased the hip extensor impulse and the recruitment of the hip extensors. In contrast, performing a forward lunge with the trunk extended did not alter joint impulse or activation of the lower extremity musculature. LEVEL OF EVIDENCE: Therapy, level 5.

STUDY DESIGN: Single-group repeated-measures study. OBJECTIVE: To examine the test-retest reliability of the timed up and go (TUG) test and its validity for measuring change and predicting length of stay (LOS) on an inpatient orthopaedic rehabilitation ward. BACKGROUND: The TUG test is used to measure functional mobility of persons with musculoskeletal conditions but it has not been thoroughly tested for use in an inpatient orthopaedic rehabilitation ward. METHODS AND MEASURES: The TUG test was administered to 142 patients on admission to an orthopaedic rehabilitation ward 7 to 10 days after admission and on discharge. To test reliability, 24 subjects had these tests repeated 1 day after admission, and the intraclass correlation (ICC) and standard error of measurement (SEM) were calculated. Change scores of the TUG test were evaluated against change scores in pain and function, and the rating of improvement of the patient and therapist. The standardized response mean (SRM) was also calculated. A regression analysis was performed to determine whether the admission TUG test score could predict LOS. RESULTS: The ICC of the TUG test was 0.80 and the SEM was 10.2 seconds. The change in TUG test scores correlated with the changes in pain (r = 0.21, P<.01) and function (r = -0.23, P<.01), and resulted in an SRM of 0.89 for subjects rated as improved. The admission TUG test scores accounted for only 3.4% of the variance in inpatient LOS. CONCLUSION: The TUG test is reliable and valid to assess group change of inpatients on an orthopaedic rehabilitation ward but is not a good predictor of LOS. LEVEL OF EVIDENCE: Prognosis, level 1b.

Resident's Case Problem
Michael D. Ross, John M. Cheeks
STUDY DESIGN: Resident's case problem. BACKGROUND: The purpose of this paper is to provide the examination of and decision-making process for a patient referred to physical therapy for the treatment of neck pain following trauma. She was found to have an underlying odontoid fracture that precluded physical therapy intervention. DIAGNOSIS: This case involved a 73-year-old woman who had a sudden onset of neck and left upper extremity pain after a fall 15 days prior to her initial physical therapy visit. Conventional cervical spine radiographs completed 1 day prior to her initial physical therapy visit were negative for a fracture. However, several components of this patient's history and physical examination were consistent with a condition for which physical therapy intervention would not be indicated until more definitive cervical spine diagnostic imaging had been completed; more specifically, the physical therapist was primarily concerned about the possibility of an undetected fracture. The referring physician was contacted and immediate magnetic resonance imaging was requested, which revealed a type II fracture of the odontoid. Thirty-four days after her fall, the patient underwent a C1-C2 fusion. DISCUSSION: When evaluating patients with neck pain who have a history of cervical spine trauma, it is important that physical therapists understand the clinical findings associated with cervical spine fractures, as these findings provide guidance for the use of cervical spine diagnostic imaging and medical referral prior to implementing physical therapy interventions. LEVEL OF EVIDENCE: Diagnosis, level 4.

STUDY DESIGN: Control laboratory study consisting of preintervention and postintervention measurements. OBJECTIVE: To determine the effects of a putting practice session on the kinematics of full golf swings made by skilled male golfers. BACKGROUND: Skilled golfers perform putting practice for prolonged periods. The combination of sustained trunk flexion with minimal trunk motion may affect the endurance capacity of the trunk extensor muscles. Because of their important role in the golf swing, any impairment of the trunk extensors may negatively influence full-swing kinematics, but this has not been previously evaluated. METHODS AND MEASURES: Three-dimensional swing kinematics and holding time on the Biering-Sørensen test of isometric trunk extensor endurance were evaluated in 29 skilled male golfers before and after performing a 40-minute putting task. RESULTS: After the intervention, peak segmental speeds were reduced and total swing duration increased (mean ± SD, 36 ± 55 milliseconds). There were reductions in the magnitude of pelvis and torso axial rotation during the downswing (mean ± SD, -2.3° ± 2.6° and -2.3° ± 4.7°, respectively). The peak difference between torso rotation and pelvis rotation during early downswing was also significantly reduced by 0.9° ± 2.0° (P<.05). The effects on pelvis and torso rotation were smallest for golfers with higher body mass index (BMI). Holding time on the Biering-Sørensen test after putting practice was significantly reduced by 25.7 ± 23.8 seconds (P = .01). CONCLUSION: Changes in swing kinematics observed following 40 minutes of putting practice might have resulted from fatigue-related impairment of the trunk extensor muscles, a view supported by the poorer performance on the postintervention Biering-Sørensen test. Results showed that swing kinematics of golfers with high BMI were least affected by the putting practice. LEVEL OF EVIDENCE: Harm, level 5.

Resident's Case Problem

STUDY DESIGN: Resident's case problem BACKGROUND: Nonossifying fibroma (NOF) is the most common fibrous bone lesion in children. The lesion is usually asymptomatic, and rarely leads to pathological fractures. DIAGNOSIS: We present the case of a 12-year-old boy who appeared to be normally developed but had a pathological insufficiency fracture associated with NOF in the distal femur. He was a member of a track athletics club and ran more than 5 km every day. Seven weeks prior to the initial evaluation he felt discomfort in the left distal thigh when running and felt pain upon knee flexion. The amount of discomfort increased gradually and he began to experience pain while running 4 weeks prior to his initial evaluation. At the time of the initial evaluation, he had tenderness over the distal thigh region and there was increased pain with weight bearing. Plain radiographs showed an irregular, well-defined cortical bone lesion, suggesting NOF, with vague increased density in the bone marrow across the femur and periosteal new bone, suggesting a fracture. Computed tomography confirmed a linear fracture with increased density across the femur leading to the cortical lesion. In the process of differential diagnosis osteosarcoma, or Ewing sarcoma, and bone/joint infection were ruled out using magnetic resonance imaging. The final diagnosis based upon the images and clinical course was pathological insufficiency fracture associated with NOF. The patient was treated with initial avoidance of weight bearing using 2 crutches for ambulation, followed by progressive weight bearing over a period of 5 weeks. Active range of motion of the knee joint was allowed. Three months after onset (5 weeks after the initial evaluation), the patient had normal gait without pain, whereupon the patient resumed his sport activities, beginning with jogging. DISCUSSION: Although pathological fractures secondary to NOF in the femur are rare, NOF can cause pathological insufficiency fractures in athletes, even if the lesion is confined and small. The current case is a reminder of such a possibility. This case also provides a time course as a reference for the rehabilitation of patients in similar cases. LEVEL OF EVIDENCE: Diagnosis, level 4.

A 21-year-old right-handed male tennis player presented with a complaint of pain in the posterior aspect of the right shoulder that started suddenly, earlier that day, after hitting a tennis ball in the overhead position. The pain was initially mild and he was able to continue playing tennis for a short time. However, he eventually had to stop playing tennis as the pain gradually increased and right shoulder range of motion progressively decreased. Frontal plane magnetic resonance T2-weighted imaging showed increased signal intensity and a complete rupture of the teres major muscle belly. Sagittal plane magnetic resonance imaging showed increased signal intensity and marked enlargement of the teres major muscle. The patient was managed nonoperatively. Magnetic resonance imaging at 6 months following the injury revealed that the teres major muscle had demonstrated appropriate healing, normal signal intensity, and normal muscle size.
