“…Gait analysis has been used as an objective and quantitative technique for the evaluation of normal and pathological patterns of locomotion in many musculoskeletal conditions [18,19]. It has also been used for the prescription of treatment as well as evaluating the effect of different interventions in pathological states [20][21][22][23]. Therefore, it could potentially provide an alternative objective assessment tool for FAI.…”

“…The author simulated a virtual restriction in the overall range of hip movements during the gait cycle, with significant reduction in hip flexion that correlated with the severity of the slip [27]. Since then, there have been a small number of clinical studies looking at gait and the overall range of hip movements in patients with FAI [20,23,28,29]. These studies have compared patients with FAI to healthy control groups [28,29] and also looked at gait parameters in patients with FAI before and after surgery [20,23], revealing surprising and inconsistent results.…”

Gait analysis is an objective tool that has been used to assess and monitor treatment for many musculoskeletal conditions. Recently, it has been used to assess the impact of femoro-acetabular impingement (FAI) on the hip and lower limb movements. There have been a fairly limited number of studies published so far reporting unexpected and inconsistent results, which calls for more research to be conducted in this arena. In the light of the limited data available, it has been challenging to reconcile the contradictions in some of these results, and therefore no coherent conclusions could be drawn. In this short article, we attempt to explain some of the abnormal kinematic and kinetic patterns associated with FAI by highlighting similarities between the gait seen in early osteoarthritis (OA) and that of FAI. We also propose an approach for future research in this field and emphasise the importance of quantifying early OA in FAI based on magnetic resonance imaging (MRI) scans and the amount of chondral damage seen during open or arthroscopic surgery.

“…However, most movement studies examined sagittal plane imbalance [15][16][17] without examining interactions in the other planes of motion, which are used for functional activities of daily moving. Indeed, there is a lack of comprehensive understanding between shoulder and pelvic function based on the transverse plane.…”

Factors affecting shoulder–pelvic integration during axial trunk rotation in subjects with recurrent low back pain

Introduction Shoulder-pelvic integration could play a central role in the control of dynamic posture and movement. However, kinematic coordination during axial trunk rotation has not been carefully investigated in subjects with recurrent low back pain (LBP). The purpose of this study was to compare the maximum rotational angles of the shoulders and pelvis in the transverse plane between subjects with and without recurrent LBP. Materials and methods A total of 38 age-matched subjects (19 control subjects: 69.00 ± 5.75 years old and 19 subjects with LBP: 68.79 ± 5.40 years old) participated in the study. The axial trunk rotation test was conducted in the upright position with bilateral hips and knees fully extended and both feet shoulder width apart. Results The results of this study indicated that there was a difference in pelvic girdle rotation between groups (100.79 ± 26.46 in the control group, 82.12 ± 23.16 in the LBP group; t = 2.31, p = 0.02); however, there was no difference for the shoulder girdle (177.63 ± 36.98 in the control group, 156.42 ± 30.09 in the LBP group; t = 1.91, p = 0.06). There were interactions with age (F = 9.27, p = 0.004) and BMI (F = 7.50, p = 0.01) with the rotational angles of the shoulder and pelvis. Conclusion These results indicated a different pattern of trunk rotation movement with the age and BMI serving as important factors to consider for recurrent LBP. The results of our study also indicated a different pattern of shoulder and pelvic coordination with age and gender. Clinicians need to consider the consequences of limited shoulderpelvic rotational angles, especially limited rotational angle on the pelvis during trunk axial rotation. Further studies are required to determine the causes of the underlying problems for clinical decision-making and altered shoulderpelvic rotation in subjects with recurrent LBP.

Femoroacetabular impingement (FAI) has been recognized as a significant clinical problem. While hip reshaping surgery for treating FAI has had positive clinical outcomes, there remains a need for objective functional outcomes of FAI treatment. We tested the hypothesis that during walking and stair climbing significant changes in hip kinematics would occur following hip reshaping surgery that indicate restoration of normal function post-operatively. Hip and pelvic kinematics were collected for 17 FAI patients preand 1 year post-operatively and compared to 17 healthy matched controls. Prior to surgery, FAI patients had significantly reduced hip internal rotation and hip sagittal plane range of motion during walking (p ¼ 0.01, p < 0.001, respectively) and stair climbing (p ¼ 0.01, p < 0.001, respectively) as compared with controls. Post-operatively, these motions were restored to normal during walking (p ¼ 0.70, p ¼ 0.46, respectively), but remained significantly reduced in the FAI patients during stair climbing (p ¼ 0.03, p < 0.001, respectively). These results have important implications for understanding the functional pathomechanics of FAI and providing an objective basis for evaluating treatment outcome. The stair climbing results indicate that problems still exist in the hip joint for activities requiring higher ranges of hip motion and suggest a basis for exploring future improvements for the treatment of FAI. ß
