Conclusion and a Word of Caution
Medical imaging has transformed healthcare by providing detailed insights into the human body, facilitating accurate diagnosis and effective treatment. Understanding the technologies and clinical indications for various imaging modalities enables healthcare professionals to choose the most appropriate methods for their patients. Continued advancements in imaging technology promise even greater precision, reduced radiation exposure, and improved patient outcomes.
With that said, diagnostic imaging does not show pain. In the world of conservative care, imaging rarely changes the course of treatment unless there is a concern for a more profound, high-risk injury ( like cancer or fracture) or evidence-informed conservative care has failed to assist in the resolution of the condition.
There is a host of evidence (that could be a blog post in and of itself) on how premature imaging of a biologically safe pain experience can lead to prolonged pain and even push someone into chronic disability, so these technologies need to be used practically and judiciously if we are being truly patient centred with our approach to injury. In short, an image does not trump the patient’s pain experience. It serves as a valuable tool to expand the diagnostic narrative when clinically indicated.
We at South Island Physiotherapy hope this review of common musculoskeletal medical imaging techniques provides insight into why certain types of imaging may be prescribed for your condition, and we are here to help you make sense of how they can assist you in your recovery.
The anterior cruciate ligament (ACL) is one of the essential ligaments stabilizing the knee joint. ACL injuries are common, especially among athletes, and can significantly affect mobility and quality of life.
This blog post explores what an ACL tear is, its causes, symptoms, diagnosis, and the various treatment options available.
What is an ACL Tear?
The ACL is a critical ligament located in the center of the knee. It connects the femur (thigh bone) to the tibia (shin bone) and helps stabilize the knee during rotational movements. An ACL tear occurs when this ligament is stretched beyond its capacity, leading to a partial tear or complete rupture. Torn ACLs are often associated with high-impact sports that involve sudden stops, pivots, or jumps, such as soccer, basketball, and skiing.
Causes of ACL Tears
Sudden Changes in Direction: Rapid pivots or changes in direction can place excessive strain on the ACL.
Jumping and Landing: Incorrect landing techniques from a jump can stress the knee joint.
Direct Impact: A direct blow to the knee, often seen in contact sports, can cause the ACL to tear.
Genetic Factors: Some individuals may have a genetic predisposition to ACL injuries due to differences in muscle strength, coordination, or ligament structure.
Symptoms of an ACL Tear
Common symptoms include:
A loud “pop” sound at the time of injury
Severe pain and inability to continue activity
Rapid swelling of the knee
Loss of range of motion
A feeling of instability or “giving way” in the knee
Diagnosing an ACL Tear
Diagnosis typically involves a combination of physical exams and imaging tests:
Physical Exam: Doctors may perform specific tests like the Lachman test and the pivot shift test to assess knee stability.
Magnetic Resonance Imaging (MRI): An MRI scan provides detailed images of the soft tissues, helping confirm the extent of the ACL tear and any associated injuries like a torn meniscus.
X-rays: Although X-rays do not show soft tissues like the ACL, they can help rule out bone fractures.
Treatment Options for ACL Injuries
Treatment for ACL injuries depends on the severity of the ligament injury, the patient’s activity level, and overall health. Options include both non-surgical and surgical approaches.
Non-Surgical Treatment
Non-surgical treatments are often considered for patients with partial tears, lower activity levels, or certain medical conditions. These treatments focus on rehabilitation and strengthening the muscles around the knee to compensate for the injured ligament.
Rest and Ice: Initial treatment includes rest and applying ice to reduce swelling.
Bracing: Knee braces may be used to provide stability during healing and activities.
Activity Modification: Patients may need to avoid activities that stress the knee excessively for a period of time soon after the injury while they heal and re-condition the area.
Surgical Treatment
Surgery is often recommended for active individuals or those with complete tears and significant knee instability. The most common surgical procedure for ACL injuries is ACL reconstruction.
ACL Reconstruction Surgery
ACL reconstruction surgery involves replacing the torn ACL with a graft. The types of grafts used for reconstruction include:
Autografts: Tissue taken from the patient’s own body, typically from the patellar tendon, hamstring tendon, or quadriceps tendon.
Allografts: Donor tissue from another part, used when autografts are not suitable.
The procedure is usually performed arthroscopically, involving small incisions and the use of a camera to guide the surgery. This minimally invasive approach results in less post-operative pain and quicker recovery times compared to traditional open surgery.
Post-Surgery Rehabilitation
Rehabilitation following ACL reconstruction is critical for successful recovery. A typical post-surgery rehabilitation program includes several phases:
Goals: Reduce pain and swelling, protect the graft, and begin gentle range of motion exercises.
Activities: Rest, ice application, compression, elevation, and use of crutches. Begin gentle knee bending and straightening exercises.
Phase 2: Early Rehabilitation Phase (2-6 weeks)
Goals: Achieve full range of motion, improve weight-bearing capacity, and begin strengthening exercises.
Activities: Continue with range of motion exercises, start weight-bearing exercises, and initiate muscle strengthening exercises focusing on the quadriceps and hamstrings.
Goals: Build strength, improve knee stability, and enhance proprioception.
Activities: Increase the intensity of strengthening exercises, incorporate balance and coordination exercises, and start low-impact aerobic exercises like cycling or swimming.
Phase 4: Advanced Strengthening and Functional Training Phase (3-6 months)
Goals: Restore full strength and function, and prepare for return to sports or high-demand activities.
Activities: Continue strengthening and functional exercises, introduce sport-specific drills, and gradually increase activity intensity and complexity.
Phase 5: Return to Sport Phase (6-12 months)
Goals: Safely return to pre-injury level of sports or activities.
Activities: Complete advanced sport-specific training, undergo functional testing to ensure readiness, and slowly reintegrate into competitive sports.
Alternative and Adjunct Treatments
In addition to the primary treatment options, there are alternative and adjunct treatments that can aid in recovery and improve outcomes.
Platelet-Rich Plasma (PRP) Therapy
PRP therapy involves injecting a concentration of the patient’s own platelets into the injured area to promote healing. While research is ongoing, some studies suggest PRP can enhance tissue repair and reduce recovery time.
Stem Cell Therapy
Stem cell therapy is an emerging treatment that uses stem cells to promote the regeneration of damaged tissues. This approach is still in the experimental stage for ACL injuries, but it shows promise for the future.
Neuromuscular Training
Neuromuscular training focuses on improving the communication between the nervous system and muscles to enhance knee stability and prevent re-injury. This can be an important component of both non-surgical and post-surgical rehabilitation programs.
Conclusion
ACL injuries are significant and can impact an individual’s ability to perform daily activities and participate in sports. Understanding the available treatment options, both non-surgical and surgical, is crucial for making informed decisions about care and recovery. Whether opting for conservative management or ACL reconstruction surgery, a comprehensive rehabilitation program tailored to the individual’s needs is essential for optimal recovery and a successful return to normal activities.
Consultation with healthcare professionals such as orthopaedic surgeons and physical therapists, like those found at South Island Physiotherapy, is vital to determine the best treatment plan based on the severity of the ligament injury, the patient’s lifestyle, and their long-term goals. With proper treatment and rehabilitation, many individuals can successfully recover from an ACL injury and regain full knee function.

In this comprehensive guide, we’ll delve into the evidence supporting the significance of strength training for runners, explore key exercises tailored for optimal results, and provide a structured approach to integrating strength training into your running regimen.
Weight Training Can Have Huge Benefits
Strength training isn’t just a complementary activity for runners; it’s a cornerstone of performance enhancement and injury prevention. Research across various scientific journals underscores the profound impact that strength training can have on a runner’s capabilities.
1. Enhanced Running Economy: A seminal study published in the Journal of Strength and Conditioning Research elucidated that integrating heavy strength training into a runner’s routine significantly improves running economy. Running economy refers to the energy cost of maintaining a specific pace, and improvements in this metric translate to enhanced endurance and faster race times. By strengthening key muscle groups, runners can sustain their pace with reduced energy expenditure, unlocking their full potential on the track or trail.
2. Mitigation of Injury Risk: Running is a repetitive, high-impact activity that places increased stress on the musculoskeletal system. Consequently, runners are susceptible to a myriad of overuse injuries, ranging from shin splints to stress fractures. However, research published in the British Journal of Sports Medicine affirms that targeted strength exercises can effectively reduce the risk of such injuries. By fortifying muscles and connective tissues, strength exercises for runners address underlying imbalances and weaknesses, thereby bolstering the body’s resilience against common running-related ailments.
3. Optimization of Running Mechanics: Efficient running mechanics are pivotal for maximizing performance and minimizing the risk of injury. Weaknesses or imbalances in muscle strength can compromise biomechanical integrity, leading to inefficiencies and increased strain on certain body regions. Through exercises such as squats, lunges, and single-leg movements, runners can enhance their stability, balance, and coordination. These improvements translate to a smoother stride pattern, reduced ground contact time, and enhanced energy transfer, ultimately propelling runners toward their goals with greater efficiency.
Key Exercises for Runners
Having established the importance of strength training, let’s delve into a curated selection of exercises tailored specifically for runners:
4. Squats: The squat reigns supreme as one of the most effective compound exercises for runners. By engaging the quadriceps, hamstrings, glutes, and core, squats facilitate the development of lower body strength and power essential for propulsion during runs. Whether performed with a barbell, dumbbells, or bodyweight alone, squats offer a versatile means of building functional strength while concurrently improving joint stability and mobility.
5. Lunges: Lunges encompass a spectrum of dynamic movements that target various muscle groups in the lower body. Forward lunges, reverse lunges, and lateral lunges engage the quadriceps, hamstrings, glutes, and hip stabilizers, making them invaluable for correcting muscular imbalances and enhancing unilateral strength. Additionally, lunges promote proprioception and kinesthetic awareness, fostering greater coordination and control during running strides.
6. Bodyweight Exercises: While running primarily engages the lower body, neglecting the upper body and core can compromise overall performance and stability. Incorporating bodyweight exercises such as push-ups, pull-ups, planks, and dips into your strength training regimen ensures a well-rounded approach to muscular development. Strong arms, shoulders, and core muscles contribute to improved posture, reduced upper body fatigue, and enhanced arm drive—factors that can significantly impact running efficiency, especially during prolonged efforts.
7. Single-Leg Exercises: Running is fundamentally a series of single-leg movements, making unilateral strength crucial for biomechanical symmetry and injury prevention. Single-leg squats, Bulgarian split squats, step-ups, and single-leg deadlifts challenge balance, stability, and coordination while effectively targeting each leg independently. By addressing discrepancies in strength and mobility between the limbs, these exercises promote functional symmetry and reduce the likelihood of compensatory patterns that may predispose runners to overuse injuries.
Creating a Structured Strength Training Plan
To capitalize on the benefits of strength training for running, it’s imperative to devise a structured plan that complements your running schedule and goals. Here’s a systematic approach to integrating strength training into your weekly routine:
8. Frequency: Plan to incorporate 2-3 dedicated strength training sessions per week, ideally on non-consecutive days, to allow for adequate recovery between sessions. Consistency is key—committing to regular strength workouts will yield cumulative benefits over time.
9. Exercise Selection: Prioritize compound movements that recruit multiple muscle groups simultaneously, such as squats, lunges, deadlifts, and push-ups. Supplement these foundational exercises with targeted drills aimed at addressing specific weaknesses or imbalances identified through functional assessments or gait analysis.
10. Progressive Overload: Adopt a progressive approach to resistance training by gradually increasing the intensity, volume, or complexity of your workouts over time. Whether through incremental weight increments, additional repetitions, or advanced variations of exercises, progressive overload stimulates continuous adaptations in strength, endurance, and neuromuscular coordination.
11. Periodization: Implement periodization principles to vary the focus and intensity of your strength training across different phases of your training cycle. Incorporate periods of higher volume of lifting in the off seasons ( 2-4x/wk) and lower volume of running ( 1-2x/wk), which, through the year, changes to a higher volume of running and lower volume intensity as competition or peak season approaches allows for a balanced workload. This reduces overtraining and burnout while promoting movement variability and maximum performance yield during the running season.
Conclusion
In the pursuit of running excellence, strength training emerges as a potent ally, capable of elevating performance and fortifying resilience against injury. By integrating evidence-based strength training principles and key exercises into your regimen, you can unlock your full potential as a runner and embark on a journey of sustained improvement and achievement. Strengthen your body, empower your stride, and embrace the transformative impact of heavy strength training—it’s the key to maximizing your stride and conquering new horizons with confidence and vigour.
Spotlight on Office Ergonomics: Setting Up Your Desk and Workstation | CCOHS Tips
In today’s modern world, where many of us spend the majority of our day seated at a desk, it’s crucial to prioritize the design and arrangement of our workspaces. The concept of ergonomics, which focuses on optimizing human well-being and performance in the working environment, plays a pivotal role in achieving this goal. By understanding and implementing key ergonomic principles, individuals can create workstations that foster comfort, productivity, and long-term health. In this comprehensive guide, we’ll delve into the intricacies of desk ergonomics and workstation setup, exploring the science behind it and providing practical tips for implementation.
Understanding the Science of Ergonomics
Ergonomics is the scientific discipline concerned with designing environments, products, and systems to accommodate the needs and capabilities of individuals. In the context of office ergonomics, the goal is to create workspaces that promote postural resiliency, reduce physical strain, and enhance overall well-being. By aligning the physical requirements of the task with the capabilities of the human body, ergonomic principles aim to minimize the risk of musculoskeletal disorders and improve efficiency and satisfaction in the workplace.
Key Elements of Desk Ergonomics
1. Desk and Chair Height
The height of your desk and chair is pivotal in maintaining proper alignment and reducing strain on your body. Ideally, your desk should be at a height that allows your elbows to rest comfortably at a 90-degree angle when typing, with your wrists straight and parallel to the floor. Similarly, your chair should be adjusted so that your feet rest flat on the floor or on a footrest, with your thighs parallel to the ground and your lower back supported by the chair’s lumbar cushion.
2. Keyboard and Mouse Placement
The placement of your keyboard and mouse can significantly impact your comfort and productivity. Position them at a height that allows your wrists to remain relaxed at about 30 degrees extension (this does not need to be an exact science).
