hip manipulation for improved strength in patients with hip pain

Conditions: Hip Pain

Summary: the purpose of this study is to investigate the potential effects of an unrestrained femoral internal rotation (ufir) manipulation technique on hip external rotation strength in individuals with nonspecific hip pain. the results of this study may help physical therapists and other healthcare professionals to better understand the effectiveness of this technique in improving hip strength and function in patients with nonspecific hip pain.

background and rationale hip pain is a prevalent and debilitating condition affecting adults of all ages and activity levels, with significant impact on daily function. in athletes, the rates of hip injuries are particularly high. the heterogeneity of nonspecific hip pain, coupled with limited research on accurate diagnosis and treatment, poses challenges for physical therapists. this study focuses on the potential of joint manipulation, particularly the unrestrained femoral internal rotation (ufir) technique, to improve hip external rotation strength in individuals with nonspecific hip pain and weakness. while strength training is commonly used to address hip weakness, there\&#39;s a lack of research on alternative approaches like joint manipulation. this research seeks to bridge this gap and explore the potential benefits of ufir manipulation in enhancing hip function and reducing pain. research procedures design: prospective, randomized, controlled trial setting: skye physiotherapy, columbia, md sample: 24 adults (18-55 years) with nonspecific hip pain and ipsilateral hip external rotation weakness intervention: experimental group receives ufir manipulation, control group receives sham manipulation outcome measures: bilateral hip external rotation strength assessed by manual muscle testing (mmt) and hand-held dynamometer (hhd) at baseline, immediately post-intervention, and 1-week follow-up. data analysis: descriptive statistics, friedman test, kruskal-wallis test, anova, and repeated measures anova will be used to analyze data. study procedures recruitment: participants will be recruited through flyers and social media platforms. screening and enrollment: eligible participants will complete an electronic health screening form and provide informed consent. randomization: participants will be randomly assigned to either the experimental or control group. intervention: the examiner will administer ufir manipulation to the experimental group and sham manipulation to the control group. assessments: hip external rotation strength will be measured using mmt and hhd at baseline, immediately post-intervention, and at 1-week follow-up. data analysis: statistical analysis will be performed to assess changes in hip external rotation strength within and between groups. internal validity and generalizability the study acknowledges potential threats to internal validity, including testing effects, instrumental bias, and experimenter bias. measures to mitigate these threats include standardized techniques, a one-week interval between assessments, and randomization. the study aims to recruit a diverse sample from howard county, md, to enhance external validity and generalizability of findings. conclusion this study aims to contribute to the understanding of the potential benefits of joint manipulation, specifically ufir, in improving hip external rotation strength and function in individuals with nonspecific hip pain and weakness. the findings may inform clinical practice and provide alternative treatment options for this patient population.
