Background: The hip is a structure of the human body in which occurs the junction of bone, articular, muscular and ligament structures. It is in the coxofemoral joint and has the function of supporting the whole-body weight, being one of the main joints responsible for ambulation. Objectives: To analyze the comparison of neural mobilization and rhythmic stabilization techniques in range of motion (ROM) and hip pain. Methods: The sample was composed by 20 patients, with mean age of 54±6 years, were divided into two groups of 10 patients: the patients who received the neural mobilization technique (G1) and the patients who received the rhythmic stabilization technique (G2). Results: The mean age of each group was 56±6 years (G1) and 52±6 years (G2). Among the evaluated, 12 (60%) were female, 14 (70%) were married, predominating the profession of housewife (35%). The great majority of the participants (95%) presented pain to the active movement, mainly to the movements of hip flexion and abduction. Regarding passive mobilization, 70% referred pains, predominating to the movements of hip external rotation and abduction. Conclusion: It was concluded that the neural mobilization and rhythmic stabilization techniques had satisfactory results in relation to ROM and pain in the hip region, but rhythmic stabilization had a greater gain of ROM and decrease of pain.

Context Inadequate hip range of motion (ROM) and isometric strength (ISO) may interfere with energy flow through the kinetic chain and result in increased injury susceptibility. Objective To examine the relationship of hip ROM and ISO with energy flow through the trunk and pitching-arm segments during the windmill softball pitch in youth athletes. A subsequent purpose was to examine the relationship between energy flow and pitch speed. Design Descriptive laboratory study. Setting University research laboratory. Patients or Other Participants A sample of 29 youth softball pitchers (age = 11.2 ± 1.3 years, height = 155.0 ± 10.4 cm, mass = 53.2 ± 12.6 kg). Main Outcome Measure(s) Bilateral hip internal-rotation and external-rotation (ER) ROM and ISO were measured. Net energy outflow and peak rates of energy outflow from the distal ends of the trunk, humerus, and forearm were calculated for the acceleration phase of the windmill softball pitch, and pitch speed was measured. Results Regression analysis revealed an effect of drive-hip ER ISO on the net energy flow out of the distal ends of the trunk (P = .045) and humerus (P = .002). Specifically, increased drive-hip ER ISO was associated with increased net energy outflow from the trunk to the humerus and from the humerus to the forearm. No significant effects of hip ROM or other hip ISO measures were observed. Additionally, pitchers who achieved higher peak rates of distal outflow tended to achieve higher pitch speeds. Conclusions An association was present between drive-hip ER ISO and the net energy flow out of the distal ends of the trunk and humerus during the acceleration phase of the windmill softball pitch, emphasizing the importance of hip and lower body strength in executing the whole-body windmill pitch. Overall, energy-flow analysis is an interesting new way to analyze pitching mechanics and will aid in furthering our understanding of performance and injury risk in windmill softball pitching.

Abstract Context:Inadequate hip range of motion (ROM) and isometric strength (ISO) may interfere with energy flow through the kinetic chain and result in increased injury susceptibility. Objective:To examine the relationship of hip ROM and ISO with energy flow through the trunk and pitching arm segments during the windmill softball pitch in youth athletes.

Participants:A sample of 29 youth softball pitchers (11.2±1.3 yrs.; 155.0±10.4 cm; 53.2±12.6 kg). Main Outcome Measure(s):Bilateral hip internal rotation (IR) and external rotation (ER) ROM and ISO were measured. Net energy outflow and peak rates of energy outflow from the distal ends of the trunk, humerus, and forearm were calculated for the acceleration phase of the windmill softball pitch, and pitch speed was measured. Results:Regression analysis revealed a significant effect of drive hip ER ISO on the net energy flow out of the distal ends of the trunk (p=0.045) and humerus (p=0.002). Specifically, increased drive hip ER ISO was associated with increased net energy outflow from the trunk to the humerus and from the humerus to the forearm. No significant effects of hip ROM or other hip ISO measures were observed. Additionally, pitchers who achieved higher peak rates of distal outflow tended to also achieve higher pitch speeds. Conclusions:There is an association between drive hip ER ISO and the net energy flow out of the distal ends of the trunk and humerus during the acceleration phase of the windmill softball pitch, emphasizing the importance of hip and lower body strength in the execution of the whole-body windmill pitch. Overall, energy flow analysis is an interesting new way to analyze pitching mechanics and will aid in further understanding of performance and injury risk in windmill softball pitching.

Background:Hip pain is associated with reduced muscle strength, range of movement (ROM), and function. Hip arthroscopy is undertaken to address coexistent intra-articular pathologies with the aim of reducing pain and improving function.Purpose:To evaluate changes in strength and ROM in a cohort with chondrolabral pathology before surgery to 3 and 6 months after hip arthroscopy.Study Design:Case series; Level of evidence, 4.Methods:Sixty-seven individuals with hip pain who were scheduled for hip arthroscopy were matched with 67 healthy controls. Hip strength and ROM were collected preoperatively and at 3 and 6 months postoperatively. Repeated measures analysis of variance evaluated whether strength and ROM differed between limbs and among time points. Bonferroni post hoc tests determined differences in hip strength and ROM among testing times and between the hip pain group and matched controls.Results:Hip extension, internal rotation (IR), external rotation (ER), and adduction ( P < .040) strength were greater at 3 months after surgery; all directions, including flexion, abduction, and squeeze, were greater at 6 months ( P < .015). Hip flexion ROM was greater at 3 months after surgery ( P = .013). Flexion, IR, and ER ROM was greater at 6 months ( P < .041). At 6 months, IR ROM ( P = .003) and flexion, IR, and ER strength ( P < .005) remained less than matched controls.Conclusion:With the exception of squeeze and flexion, all directions of hip strength and hip flexion ROM are significantly improved 3 months after arthroscopy to address chondrolabral pathology. By 6 months after arthroscopy, strength in all directions and flexion and rotation ROM are significantly improved in both limbs, but hip flexion, IR, and ER strength and IR ROM remain significantly less than that of healthy matched controls in both limbs.

Abstract The aim of this study was to determine (i) the reliability of hip range of motion measurement among experienced arthroscopic hip preservation surgeons and (ii) the magnitude of hip flexion change with posterior pelvic tilt. Five experienced arthroscopic hip preservation surgeons (5–18 years of hip surgery experience) performed passive hip range of motion (internal and external rotation), flexion (contralateral hip extended) and flexion with posterior pelvic tilt (contralateral hip maximally flexed) on five young healthy asymptomatic volunteers (three males, two females; 34.4 ± 10.7 years of age). Motion was measured via digital photography and goniometry. Inter-observer reliability was calculated via two-way mixed, single measures, intra-class correlation coefficient. Paired t-test was utilized to compare hip flexion (with contralateral hip extended) to hip flexion with posterior pelvic tilt (with contralateral hip in forced flexion). The reliabilities of measurements of hip flexion with posterior pelvic tilt and external rotation were excellent, that of hip flexion was fair, and that of hip internal rotation was poor. The magnitude of hip flexion increase with posterior pelvic tilt was 17.0° ± 3.0° (P &lt; 0.001). The reliability of hip range of motion measurement by five experienced arthroscopic hip preservation surgeons was excellent for measures of hip flexion with posterior pelvic tilt and external rotation. Contralateral maximal hip flexion significantly increased ipsilateral hip flexion (approximately 17°). Level of Evidence: Diagnostic, level III (without consistently applied reference standard)

Aims In computer simulations, the shape of the range of motion (ROM) of a stem with a cylindrical neck design will be a perfect cone. However, many modern stems have rectangular/oval-shaped necks. We hypothesized that the rectangular/oval stem neck will affect the shape of the ROM and the prosthetic impingement. Methods Total hip arthroplasty (THA) motion while standing and sitting was simulated using a MATLAB model (one stem with a cylindrical neck and one stem with a rectangular neck). The primary predictor was the geometry of the neck (cylindrical vs rectangular) and the main outcome was the shape of ROM based on the prosthetic impingement between the neck and the liner. The secondary outcome was the difference in the ROM provided by each neck geometry and the effect of the pelvic tilt on this ROM. Multiple regression was used to analyze the data. Results The stem with a rectangular neck has increased internal and external rotation with a quatrefoil cross-section compared to a cone in a cylindrical neck. Modification of the cup orientation and pelvic tilt affected the direction of projection of the cone or quatrefoil shape. The mean increase in internal rotation with a rectangular neck was 3.4° (0° to 7.9°; p < 0.001); for external rotation, it was 2.8° (0.5° to 7.8°; p < 0.001). Conclusion Our study shows the importance of attention to femoral implant design for the assessment of prosthetic impingement. Any universal mathematical model or computer simulation that ignores each stem’s unique neck geometry will provide inaccurate predictions of prosthetic impingement.

Background: Patients with frozen shoulder who fail conservative therapy need surgical treatment and aggressive post-operative rehabilitation. Objective: To evaluate the effect of continuous cervical epidural analgesia on pain scores and range of motion of the shoulder joint in patients undergoing surgery for treatment of refractory frozen shoulder. Methods: Twenty-one patients with refractory frozen shoulder who had failed conservative treatment and undergone surgical procedure (manipulation under anesthesia or capsular release) were identified and the data were collected retrospectively. These patients had cervical tunneled epidural catheter (TEC) placement for continuous infusion of a mixture of lowdose narcotic and local anesthetics at the time of surgery and were discharged home with the catheter in place. They were then involved in an active physical therapy program to increase the range of motion of the affected shoulder joint. The patients (N = 21) were followed for a median of 4.7 weeks. They were assessed for range of motion, function, visual analog pain scores (VAS), and opiate use before the surgery and after tunneled epidural catheter removal. Results: Statistically significant changes from the time of placement to the time of removal of the tunneled epidural catheter (TEC) were observed for VAS pain score and range of motion of the shoulder in forward flexion, external rotation, and internal rotation. The mean rate of change among the patients for pain score, forward flexion, external rotation, and internal rotation was also computed. The mean change per week in each of these 4 measurements significantly differed from zero. 33 percent of the patients returned to work within one week. Conclusion: Our data show that the continuous infusion of epidural opioids and local anesthetics through a tunneled cervical epidural catheter during the rehabilitation phase after shoulder surgery for adhesive capsulitis may be a safe and effective tool for post-operative pain control and to facilitate rehabilitation.

Background and Purpose Up to 38% of children receiving treatment for acute lymphoblastic leukemia (ALL) develop osteonecrosis, often without symptoms. Little is known about the association between the degree of osteonecrosis and functional mobility in this population. The purpose of this study was to examine relationships among the degree of osteonecrosis, pain, range of motion (ROM), and functional mobility in people with ALL. Subjects Thirty-three subjects aged 5 to 27 years with ALL and osteonecrosis participated. Methods The extent of osteonecrosis was determined by magnetic resonance imaging (MRI) of the hip and knee according to 2 classification systems, including the Association Research Circulation Osseous (ARCO) and a knee staging scale. Pain, hip and knee ROM, and the Timed Up and Down Stairs (TUDS) Test were used as measures. Results Correlations were observed between ARCO and hip pain (r=.34), between hip flexion ROM and hip pain (r=−.34), and between knee pain and time on the TUDS Test (r=−.35). Discussion and Conclusion Physical therapists should consider that people with ALL may have hip or knee osteonecrosis without clinical symptoms. This notion supports the need for MRI in addition to a comprehensive examination of functional mobility.

Abstract The purpose of this study was to determine which variables of the range of motion (ROM) and strength of the hip, and ankle are associated with squat depth. In total, 101 healthy subjects (64 males, 37 females) participated in the study. Outcome measures consisted of the ROM of hip flexion, hip internal rotation, external rotation, ankle dorsiflexion with an extended and flexed knee joint, and strength of the hip flexor and ankle dorsiflexor. Squat depth was measured using SIMI motion analysis software. Pearson correlation was used to determine the relationship between variables and squat depth. Multiple stepwise regression analysis was performed to determine variables associated with squat depth. The multiple regression model indicated that ankle dorsiflexion with a flexed knee and the hip flexion ROM were significantly associated with squat depth in male subjects (R2 = 0.435) and ankle dorsiflexion with an extended knee and dorsiflexor strength were significantly associated with squat depth in female subjects (R2 = 0.324). Thus, exercises to increase the ROM of the ankle dorsiflexion, hip flexion, and dorsiflexor strength can be recommended to improve squat performance. Future studies should assess an increased ROM of the ankle dorsiflexion, hip flexion, or dorsiflexor strength effect on deep squat performance.

ABSTRACT Objective: To determine the frequency of hip pain in competitive bodybuilders over three different bodybuilding competitions. Methods: This study evaluated bodybuilders recruited from three competitions during the year of 2016. All participants provided their informed consent and the study received IRB approval. Training routine, health condition, level of success on competitions, history of hip pain and physical examination of the hip were evaluated. Results: 113 bodybuilders were evaluated, mean age was 30.5 ± 8.65 years and mean BMI was 25.2 ± 3.65 kg/m2. Mean values for hip flexion, adduction, abduction, internal rotation, external rotation and distance between the knee and the table (FABER distance) were 116 ± 13, 23 ± 8, 71 ± 12, 40 ± 10, 36 ± 9 and 19 ± 4, respectively. Eight (7%) participants presented hip pain within the week prior to examination and only 2 (1,7%) presented with anterior impingement sign. None of the athletes who reported hip pain interrupted their physical training or performance. Conclusion: Symptomatic athletes continued their training program under the presence of hip pain. The frequency of hip pain among bodybuilders is high and may be underestimated in this study. Level of Evidence IV, Case series.

Introduction: Little is known about the loading patterns in unilateral hip osteoarthritis (OA) and their relationship to radiographic severity and pain. We aimed to examine the loading patterns at the hips of those with unilateral symptomatic hip OA and identify associations between radiographic severity and pain with loading alterations. Methods: 61 subjects with symptomatic unilateral hip OA underwent gait analyses and evaluation for radiographic severity (Kellgren-Lawrence [KL]-grade) and pain (visual analogue scale) at bilateral hips. Results: Hip OA subjects had greater range of motion and higher hip flexion, adduction, internal and external rotation moments at the contralateral, asymptomatic hip compared to the ipsilateral hip ( p < 0.05). Correlations were noted between increasing KL-grade and increasing asymmetry of contralateral to ipsilateral hip loading ( p < 0.05). There were no relationships with pain and loading asymmetry. Discussion: Unilateral symptomatic hip OA subjects demonstrate asymmetry in loading between the hips, with relatively greater loads at the contralateral hip. These loading asymmetries were directly related to the radiographic severity of symptomatic hip OA and not with pain. Conclusion: Additional research is needed to determine the role of gait asymmetries in disease progression.
