“…The side bridge test is assumed to be a measure of trunk muscle strength endurance. 25,29 For the single-leg rise test, participants were seated on the edge of a plinth, with the test foot placed in a comfortable position on the floor in front of the plinth. The contralateral leg was held straight out in front of the body, with the arms resting by the participant's side.…”

T t STUDY DESIGN:Cross-sectional study. T t BACKGROUND:Functional task performance in patients with chondrolabral pathology following hip arthroscopy is unknown. T t OBJECTIVES:To investigate in people with chondrolabral pathology following hip arthroscopy (1) the bilateral differences in functional task performance compared to controls, (2) the association of hip muscle strength with functional task performance, and (3) the association of functional task performance scores with good outcome, as measured by International Hip Outcome Tool score. T t METHODS:Seventy-one patients who had unilateral hip arthroscopy for hip pain and 60 controls were recruited. Patient-reported outcomes included the 4 subscales of the International Hip Outcome Tool. Hip muscle strength measures included abduction, adduction, extension, flexion, external rotation, and internal rotation. Functional tasks assessed included the single hop test, the side bridge test, and the single-leg rise test. For aim 1, analyses of covariance tests were used. For aim 2, stepwise multiple linear regression analyses were used. For aim 3, receiver operating characteristic curve analyses were used. T t RESULTS:Compared to controls, the chondrolabral pathology group had significantly worse performance on both legs for each of the functional tasks (P<.001). Greater hip abduction strength was moderately associated with better performance on functional tasks in the chondrolabral pathology group (adjusted R 2 range, 0.197-0.407; P<.001). Cutoff values associated with good outcome were 0.37 (hop distance/height) for the single hop, 16 repetitions for the single-leg rise, and 34 seconds for the side bridge test. T t CONCLUSION:Patients with hip chondrolabral pathology had reduced functional task performance bilaterally 12 to 24 months after unilateral hip arthroscopy when compared to controls. T t LEVEL OF EVIDENCE: Therapy/symptom prevalence, level 3b.

“…The limit of 180 seconds was chosen based on a survey of normative data for a healthy population. 2,4,7,14,16,22,23 Participants initiated a comprehensive rehabilitation program 4 to 6 weeks after surgery that consisted of isolated exercises for the lumbar extensors performed on the variable Roman chair, and integrated trunk exercises performed on the floor (quadruped, abdominals) and upright (squats, lunges) (FIGURE 2). A synopsis of the program is presented in the APPENDIX.…”

l umbar spine surgery can expedite improvements in pain and dysfunction associated with a herniated lumbar disc. 19 Consequently, over 250 000 surgeries are performed each year in the United States alone.1 A commonly used surgery is the single-level microdiscectomy ( S L M ) , in which a damaged portion of the intervertebral disc is removed. While the standard of care for therapy following a t sTuDY Design: Longitudinal single-cohort study. t MeTHoDs: Patients (n = 48) with a single-level microdiscectomy participated in a 12-week (36 sessions) comprehensive strength and endurance exercise program starting 4 to 6 weeks postsurgery. Lumbar extensor strength was quantified as the degree from horizontal on a modified Sorensen test procedure. Patients unable to assume the horizontal position were assumed to have strength deficits. Lumbar muscular endurance performance was quantified by the amount of time patients could hold the Sorensen test position at the horizontal. The time rate of lumbar muscular endurance adaptations were analyzed using longitudinal growth curve modeling.t resulTs: The adherence rate of this program was low (67%). Twenty percent of the patients were identified as having strength deficits. These deficits were corrected in all patients within 3 to 9 weeks. Linear mixed-model results suggest an improvement of 5.6 seconds in hold time per week of exercise. Both the initial level of endurance and the rates of improvements were highly individualized.t ConClusion: The time course of musculoskeletal performance adaptations in persons with a history of lumbar surgery is highly individualized. When compared to normative endurance times, the results of this study indicate that the number of sessions and duration of therapy needed to generate meaningful adaptations of the paraspinal musculature is longer than what is typically provided in the clinic postsurgery. t leVel oF eViDenCe: Therapy, level 4.

Participants were instructed to hold a static position for a long as possible the test was terminated when the subject could no longer sustain the position and the time recorded in seconds (s).…”
