Poster 137: Psychological Readiness has Stronger Relationship with Patient Reported Return to Normal than Traditional Measures of Strength and Western Ontario Shoulder Instability Index

Objectives: Literature is scarce regarding the influence of psychological readiness on return-to-play (RTP) after shoulder instability surgery. The shoulder instability-Return to Sport after Injury (SIRSI) score is a tool designed to predict whether patients are psychologically ready to return to sports after glenohumeral stabilization surgery. The objective of this study is to correlate SIRSI, and traditional measures including strength testing and Western Ontario Shoulder Instability Index (WOSI) survey with patient’s self-reported Single Assessment Numeric Evaluation (SANE) score during rehabilitation and at the time of RTP. Methods: All patients who participated in athletics who underwent arthroscopic labral repair for shoulder instability from June 2021 to December 2022 with a fellowship trained orthopaedic surgeon were eligible to participate. SIRSI and WOSI scores and strength testing (Biodex testing) were administered at 4 months postoperatively and every 2 months until clearance based on functional testing battery (>90% limb symmetry, strength, rate of force development, shoulder stability and endurance). Pearson Correlation coefficients were calculated for survey metrics between SANE with SIRSI, WOSI, and strength testing at final follow up. Strength of correlation coefficients was reported as very strong >0.80, strong (0.60-0.79), moderate (0.40-0.59), weak (0.20-0.39), and very weak (0.00-0.19). Results: Overall, 22 patients who cleared objective functional testing criteria and completed appropriate surveys at return to sport. There was a mean age of 19.8 years (range 11-44 years), with 12 males and 10 females, and the mean follow up was 11 months (6-24 months). The mean final SANE scores at these time points were 79.12 (25-100). Pearson correlation between SANE and SIRSI, WOSI at time of return-to-play was 0.92, and 0.67 respectively. The correlation coefficients for strength testing at varying positions including closed kinetic chain upper extremity stability test, posterior shoulder endurance test LSI, and peak force in Y, T, I positions LSI were weak to moderate (0.20-0.59). Conclusions: The SIRSI had a stronger correlation than WOSI to patients self-reported return to baseline (SANE scores). This finding highlights the importance of psychological readiness in return to sport compared to traditional measures of strength testing and WOSI scores. SIRSI should be incorporated into functional test batteries for shoulder instability.

Relationships between Jumping Performance and Psychological Readiness to Return to Sport 6 Months Following Anterior Cruciate Ligament Reconstruction: A Cross-Sectional Study.

Investigating the relationship between functional capacity and psychological readiness is of paramount importance when planning sport resumption following knee surgery. The aim of this study was to prospectively assess clinical and functional outcomes in athletes 6 months after primary anterior cruciate ligament (ACL) reconstruction and to evaluate whether jumping ability is related to psychological readiness to return to sport following ACL surgery. Patients who underwent ACL reconstruction were prospectively enrolled and evaluated pre-operatively and 6 months after surgery. Assessment included Lysholm score, International Knee Documentation Committee (IKDC) Subjective Knee Form, Tegner activity level, and the ACL-Return to Sport after Injury (ACL-RSI) scale. Jumping ability was instrumentally assessed by an infrared optical acquisition system using a test battery including mono- and bipodalic vertical jump and a side hop test. Patients were dichotomized by ACL-RSI into two groups: group A (ACL-RSI > 60), and group B (ACL-RSI < 60). Overall, 29 males and two females from the original study group of 37 patients (84%) were available for clinical evaluation. Mean age at surgery was 34.2 years (SD 11.3). Mean body mass index (BMI) was 25.4 (SD 3.7). Mean overall Lysholm, IKDC, and ACL-RSI scores increased from pre-operatively (p < 0.001). No differences in Tegner score were reported (p = 0.161). Similarly, improvement in most variables regarding jumping ability were observed at follow-up (p < 0.05). According to ACL-RSI, 20 subjects were allocated in group A (ACL-RSI > 60), while 11 were allocated in group B (ACL-RSI < 60). A statistically significant difference in favor of patients in group A was recorded for the post-operative Lysholm and Tegner score, as well as Side Hop test LSI level (p < 0.05), while a trend for IKDC was observed without statistical significance (p = 0.065). Patients with higher values of ACL-RSI scores showed better functional and clinical outcomes as well as improved performance 6 months after ACL reconstruction.

Influence of attachment on socio-psychological adaptation and its dynamics in the course of treatment in adolescent patients with schizotypal disorder

Summary. Purpose. Study of the influence of attachment quality (based on the analysis of its representation) on the results of treatment and socio-psychological adaptation of adolescent patients with schizotypal disorder.Materials and Methods. 41 adolescents with pseudoneurotic type of schizotypal disorder were surveyed [F 21.3]. All respondents were divided into two groups based on the type of early attachment to mother («reliable attachment» and «unreliable attachment»). A battery of 6 tests was used: a questionnaire for studying of coping-behavior ways (Lazarus R., Folkman С., WCQ, The Waysof Coping Questionnaire, 1988); test LSI, Life style index Plutchik R., Kellerman H., 1979 (in adapt.Wasserman L. I., etc., 1998), the modified questionnaire of attachment ( Yaremchuk M. V., 2005; in modific. Almazova O.V., Burmenskaya G.V., 2015), SCL-90R («Simptom Check List-90-Revised»; Derogatis, Rickels, Rock, 1976), integrative anxiety test (Bizyuk A.P, Wasserman L.I., Iovlev B.V., 2005), scale of assessment of social functioning of patients (Kotsyubinsky A.P., Sheinina N.S., etc. 2013). Studied were the features of protectively-adaptive behavior and the actual psychological symptomatic status, indicators of personal and situational anxiety, as well as features of contact with the doctor, and dynamics of indicators of social adaptation during treatment.Results. Confirmed the relationship of representation unreliable type of attachment to the mother, in patients with schizotypal disorder, and sustained violation in the sphere of relationships with parents, disorders of emotional regulation, reduce psychological adaption in general. In such patients, during the treatment process, lower compliance indicators, specific features of the protective-coping style of behavior, as well as slower rates of psychological and social recovery were revealed.Conclusion. According to the results of the study, data indicating the negative impact of unreliable attachment in adolescent patients with schizotypal disorder on psychological recovery during treatment and socio — psychological adaptation of patients in general were obtained. Psychotherapeutic recommendations are presented.

Can a User Test LSI Microprocessors Effectively?

This paper elucidates user oriented test philosophy for LSI microprocessors. Also, a low-cost incoming inspection tester is described. The significant difference between this and available testers is the use of probabilistic scheme by which the instruction, data, and control signal mixes are generated. This approach reduced significantly tester hardware and supporting software without compromise of overall test performance.
