Objective The purpose of this study was to determine the effects of lower extremity motor control exercises on knee proprioception, muscle strength, and functional level in patients with anterior cruciate ligament reconstruction (ACL-R). Materials and Methods Thirty-two of the 57 patients with ACL-R using tibialis anterior allografts were divided into two groups. Group I: lower extremity motor control exercises were added to the standard rehabilitation program. Group II: standard rehabilitation program was applied. Effects of lower extremity motor control exercises on quadriceps and hamstring muscles strength, knee joint position sense, and hop test were evaluated. Results There were no differences in muscle strength and endurance of the quadriceps and hamstring between the operative and nonoperative sides in Group I (p > 0.05) while there were significant differences in strength of the quadriceps and hamstring between the operative and nonoperative sides in Group II (p < 0.05). There were significant differences in the endurance of the quadriceps and hamstring and knee joint position sense at 15°, 45°, and 75° between the operative sides of the patients in both groups (p < 0.05). Conclusions The neuromuscular control exercises program was found to be more effective in reducing the difference in strength while the standard program was found to be more effective in reducing the difference in endurance between the operated knee and the other knee. This study revealed that neuromuscular control exercises should also be used to improve knee proprioception sense following ACL-R.

Context: The wall slide exercise is commonly used in clinic and research settings. Theraband positioning variations for hip exercises are investigated and used, but theraband positioning variations for upper extremity wall slide exercise, though not commonly used, are not investigated. Objective: To investigate the effect of different theraband positions (elbow and wrist) on scapular and shoulder muscles' activation in wall slide exercises and compare them to the regular wall slide exercise for the upper limbs. Study Design: Descriptive Laboratory Study. Setting: University Laboratory Patients or Other Participants: 20 participants with healthy shoulders Interventions: Participants performed regular and two different variations of wall slide exercises (theraband at wrist and theraband at elbow) in randomized order. Main Outcome Measures: Surface EMG activity of the trapezius muscles (upper [UT], middle [MT], and lower trapezius [LT]), infraspinatus (IS), middle deltoid (MD), and serratus anterior (SA). Results: Regular wall slide exercise elicited low activity in MD and moderate activity in SA muscles (32% MVIC), while theraband at wrist and elbow variations elicited low activity in MT, LT, IS, and MD muscles and moderate activity in SA muscles (46% and 34% MVICs, respectively). UT activation was absent to minimal (0–15% MVIC) in all wall slide exercise variations. Theraband at wrist produced lower UT/MT, UT/LT, and UT/SA levels. Conclusion: In shoulder rehabilitation, clinicians desiring to activate scapular stabilization muscles should consider using theraband at wrist variation; clinicians desiring to achieve more shoulder abduction activation and less scapular stabilization should consider theraband at elbow variation of upper extremity wall slide exercise.
