Relationship Between Functional Knee Joint Position Sense and Functional Performance Scores Following Anterior Cruciate Ligament Reconstruction (Pilot Study)

Objectives: The aim of this study was to assess the relationship between functional knee joint position sense (JPS) and functional performance following ACL reconstruction Methods: Seven male patients (mean age=32,66 ±6,47) who had undergone ACL reconstruction and 10 male healthy control subjects participated in the study. Knee joint position sense was evaluated by reproduction of 20° knee flexion angle in weight-bearing position with single and bilateral limb movement into flexion and extension. The deviations in the angle were recorded and compared to both noninjured side and healthy controls’. Functional performance was evaluated with Single Leg Hop Test in both injured and non-injured sides. The scores were also compared with healthy controls and non-injured sides. Relationship between measured values was tested with Spearman Correlation Analysis. Results: There was no significant difference in knee joint position sense in functional position between the operated and uninjured knees of patients or between patients and healthy controls (p>0,05). However, there is significant difference in Single Leg Hop test scores between operated and non-operated or between patients and healthy controls (p=0,037; p<0,05). There was no significant correlation between Single Leg Hop test scores and knee joint position sense (p>0,05). Conclusion: There was no evidence of impaired joint position sense in weight-bearing positions in subjects with ACL reconstruction but there was a decrease in functional performance. This decrease in functional performance may depend on the other parameters except proprioceptive deficits.

Is There a Relation Between Shoulder Dysfunction and Core Instability

Objectives: Little is known about the relationship between core stability and shoulder dysfunction in shoulder impingement syndrome. The purpose of this study was to analyze the difference between healthy volunteers and patients with shoulder dysfunction in regard to core stability measures. Secondary purpose was to explore the relationship between measures of core stability and measures of shoulder dysfunction. Methods: 15 patients with shoulder impingement syndrome (mean age: 32.2±4.2 years) and 15 healthy volunteers (mean age: 33.8±6.2 years) participated in this study. Sorenson test, front plank and side bridge exercise was performed to assess anterior, lateral and posterior core endurance, respectively. Simple shoulder test (SSS) and seated medicine ball throw test was used to evaluate the functions of the shoulder joints. Mann-Whitney U test was used for comparison of variables between groups. Analyses of relationships between variables were examined with Spearman correlation test. Results: There was a statistically significant difference between patients with shoulder impingement syndrome and healthy controls in core stability and function (p<0.05). A strong positive correlation was found between shoulder functional test (SSS) and lateral bridge test (r= .874, p < .05). Additionally, a modest positive correlation was found between the SSS and the Sorenson test at (r= .695, p < .05), and a weak positive correlation was found between the SSS and the front plank test at (r= .365, p < .05). Conclusion: Core stability and functional deficiency was found in patients with subacromial impingement syndrome. According to this study, greater shoulder dysfunction is correlated with greater stability deficiency. Therapists should consider incorporating core strengthening as an integral component of rehabilitation program in patients with shoulder dysfunction.

Effects of ’’Throwers Ten’’ Exercise Program on Pain and Function in Shoulder Impingement Syndrome: A Pilot Study.

Objectives: The purpose of this study was to examine the effects of Throwers Ten (T10) exercise program on pain and function in patients with shoulder impingement syndrome. Methods: Twenty subjects who were assigned by random sampling to an experimental group (n=10) to which Throwers Ten (T10) exercise and a control group (n=10) to which ordinary physical treatment were applied. A 100 mm visual analogue scale (VAS) was used to evaluate the degree of pain. The Disability of Arm, Hand, and Shoulder (DASH) score was used to assess the functions of the upper extremity. To determine the range of motion, a universal goniometer was used to measure range of shoulder motion. Wilcoxon test was employed to examine differences in pain and function of the experimental group and the control group before and after the treatment. Results: There were significant differences in function and pain of the experimental group (p<0.05). The therapeutic effect in the experimental and control groups revealed significant differences in flexion, abduction, VAS and the DASH (p< 0.05); respectively. Conclusion: The results of this study suggest that Throwers Ten (T10) exercise would be positively affected pain alleviation and functional recovery in shoulder impingement patients.

A Comparison of Dynamic Postural Stability Between Asymptomatic Controls and Male Patients One Year After ACL Reconstruction (Pilot Study)

Objectives: The purpose of this study was to determine if dynamic postural stability gained one year after ACL reconstruction in patients who received rehabilitation. Methods: Seven male patients (mean age=32,66 ±6,47) who had previously undergone ACL reconstruction (ACL-R) and 7 sex-and general physical activity matched uninjured controls included to study. Mean time since original injury was 13±3,31 months. Dynamic postural control was assessed with 20° knee flexion with Star Excursion Balance test. Each participant performed 3 trials of the anterior, posterior-medial, and posterior-lateral directional components of the SEBT. Reach distances for each directional component were compared with non-injured leg and healthy controls’. Results: There was no significant difference in all directions of Star Excursion Balance test between neither the operated and uninjured knees of patients nor between patients and healthy controls (p>0,05). Conclusion: No deficits in dynamic postural stability were present average one year after ACL reconstruction in patients who received rehabilitation. It can be said that rehabilitation is effective in the recovery of dynamic postural stability.

Upper Quarter Y-Balance Test Score of Patients with Shoulder Impingement Syndrome

Objectives: The Upper Quarter Y Balance Test (UQYBT) is a reliable upper extremity closed kinetic chain test that can be used to assess unilateral upper extremity performance in a closed chain manner. However, UQYBT was tested only in recreational athletes and there are no studies investigating UQYBT scores in patients with various upper extremity musculoskeletal injuries. The purpose of this study was to examine differences in performance on the Upper Quarter Y Balance Test between patient with shoulder impingement syndrome and healthy controls. Methods: A sample of fifteen patients with shoulder impingement syndrome (mean age 32.2±4.2 years) and fifteen healthy control (mean age 33.8±6.2 years) performed the UQYBT. UQYBT was collected bilaterally in three directions (medial, inferolateral, and superolateral). The maximum reach distance for each direction was normalized to upper extremity length (spinous process of C7 to tip of middle finger) and used for analysis Results: A significant difference in performance between patients with shoulder impingement syndrome and healthy controls existed in the medial direction (P<0.05) and the inferolateral direction (P<0.05) where the healthy controls performed better. There was no significant difference in superolateral performance. Conclusion: The results of this study suggest that patients with shoulder impingement syndrome will perform worse on the UQYBT in the medial and inferolateral directions than healthy controls. Thus, upper extremity closed kinetic chain exercises should be added in shoulder rehabilitation programs.
