Not Applicable

Completed

• Conditions: Anterior Cruciate Ligament Injuries
• Interventions: Other: Neuromuscular Training; Other: Strength Training

• Registration Number: NCT04355078
• Lead Sponsor: Riphah International University

Brief Summary

The objective of the study was to determine the effectiveness of neuromuscular physical Therapy as compared to strength training after ACL reconstruction in terms of pain, function, quality of life, strength and power of participants after ACL reconstruction.

It was a Randomized clinical trial conducted Kanaan Physiotherapy \& Spine Clinic, Lahore. Seventy-six patients were selected by purposive sampling technique and equally divided into one of two treatment groups either neuromuscular training or strength training with use of sealed envelope randomization. The study was completed in 6 months. Patients were assessed using the Cincinnati Knee Score for function, Numeric Pain Rating Scale (NPRS) for pain, SF-36 for quality of life, and Hop test (single leg, Triple, crossover and 6-meter hop) for power and strength.Patients received the treatment 3 times per week for six consecutive weeks.

Detailed Description

The knee joint problems and injuries has been rising as a result of more number of patients getting injuries in various daily livings e.g traffic and industrial accidents Ligamentous injuries are one of the commonest injuries of knee among which occurrence of Anterior cruciate ligament(ACL) injuries are of considerable importance The ACL is actually made up of many bundles of connective tissue and it has course from femur to tibia as shown in picture. The ACL is main ligament which prevents tibia to go outwards and excessive loads. When knee is in straight position ACL has 32mm length and 7-12mm width.ACL has 2 parts anteromedial bundle and posterolateral bundle. During flex position AMB goes into lengthened position and PLB goes into shorten position. It is made up of collagen fibres and its framework has proteins, glycoproteins, elastic systems, and glycoseminoglycans. Because of its elastic property it undergoes into many stresses. And it has nerve supply of tibial nerve and it has arterial supply of middle genicular artery. The Occurrence of ACL injures mostly reported among paediatric and adolescent population as compared to adult population. This factor which raises the contribution of adults to participate in sports are younger age high performance training, awareness of injury and use of better modalities. Short term complications of ACL that include loss of function, pain and reconstructive surgery period of about 24 to 36 weeks required for return to function. Reconstructive surgeries include autogenous or allogeneic graft reconstruction Many studies showed that after reconstructive surgery patients return to sports. Most (82%) patients are able to return to sport activity according to a meta-analysis results; however preinjury levels of performance are attained in only 43-65.7% of cases. Long-term complication of ACL injuries that significantly include osteoarthritis that develop later in life. One of the studies show that 50% of diagnosed patients of meniscus or ACL tear might develop osteoarthritis (OA) in the affected knee in about 10-20 years after surgery and the prevalence and severity of OA has not been shown to reduce by reconstructive surgery. Newer surgical approaches and techniques seems to reduce risk of developing osteoarthritis later in life but still questionable.

The involved leg is used if nothing else is stated that includes Walking on a treadmill, Squatting exercises, Single leg stance exercise Balance reach leg and arm exercises, Lunge exercises: anterior, lateral and posterior, Step-up and step down exercises, Single leg standing on balance mat, appropriate knee and hip position, Backwards and sideways walking for 5 steps on each side 1, 1 leg and 2 leg Wobble board Exercise and progress after every two weeks
Strength Training	Strength Training	The rehabilitation program starts two months after surgery, 45 minutes daily session, 3 times a week for 6 weeks that includes straight leg raising exercises, Supine position-isometric quadriceps contraction, Supine position-knee flexion and extension ROM exercises, the heel in contact with the bench during the ROM, Prone position-straight leg raising exercises, Prone position-knee flexion \& Extension ROM exercises, Stationary biking-before reaching 100 degrees of flexion(Progression: stair climbing and strength exercises), Standing-full weight-bearing, controlled balance double-limb support during parallel and diagonal stance, controlled knee extension, emphasis on full knee extension in weight-bearing position 3 10 reps Standing heel rising exercises both legs and one leg, 1 leg and 2 leg Wobble board Exercise, Step Up and down low height, Squatting exercises without bars/weight, Hamstrings, hip adductor and abductor strengthening exercises and progress after every two weeks

Primary Outcome Measures

Name	Time	Method
NPRS	4 months	To rate pain of patients and 1 to 3 considered as mild, 4 to 7 considered as Moderate and 8 to 10 considered as severe pain
SF-36	4 months	Quality of Life

Secondary Outcome Measures

Name	Time	Method
Cincinnati Knee score	4 months	The Cincinnati Knee Rating System is one of the most commonly used instruments to measure the results of anterior cruciate ligament reconstruction,The total score is calculated as the sum of all questions responses, with 100 representing the best/excellent knee function, and 0 representing the worst/poor knee function.
Hop Tests	4 months	A series of hop tests are routinely used in the assessment for return to sports post-injury, be it an ankle sprain, stress fracture or anterior cruciate ligament reconstruction
