Let’s break it down. Tell us about yourself and the topic we’re going over, which is DIP joint pain. You’ve written an article on this, so introduce yourself to those who may not know you.

My name is Steve Smith. I’m a doctor of physical therapy with orthopedic and strength and conditioning certifications. PT is a second career for me. I started with a bachelor’s degree in marketing and sales management but later pursued physical therapy.

That’s quite a career change. You were a dirt bag climber before, right?

Yes, I was, traveling around and climbing, even selling plasma to make rent. Then I decided to go back to school for physical therapy.

Impressive! How long have you been a physical therapist?

It’s almost been 10 years now.

Let’s dive into the topic of DIP joint pain. Can you explain the anatomy of the finger and what this injury entails?

Certainly, the DIP (Distal Interphalangeal) joint is essentially our initial point of contact with the rock. In this article, I wanted to address an injury I’ve personally experienced. Often, climbers focus heavily on finger flexors but overlook the other side of the finger, the DIP joint. It’s where the distal phalanx meets the middle phalanx, surrounded by ligaments, joint capsules, and muscles. Specifically, we’ll focus on the flexor digitorum superficialis and flexor digitorum profundus tendons. The profundus runs under the superficialis and crosses the DIP joint, which raises questions about the forces it endures during full crimp positions.

There’s been a noticeable shift towards joint-related injuries in climbers, particularly in the PIP (Proximal Interphalangeal) and DIP joints. The continuous gripping of holds, especially in the full crimp position, hyperextends the DIP joint and hyperflexes the PIP joint, leading to localized stress. Climbing stresses these joints when fingers are twisted into tight spots, such as crack climbing, or during frequent crimp usage. Microtrauma ensues, triggering inflammation, thickening of synovial fluid, chronic inflammation, joint thickening, arthritis, and bone spurs. This cycle often results in those familiar gnarly fingers we see in experienced climbers.

What’s the rehab process for DIP capsulitis, and what should climbers expect when they see a physical therapist?

When addressing DIP capsulitis, it’s crucial to recognize the symptoms, such as decreased mobility and finger pain in the last joint due to excessive crimping. Climbers should anticipate a multi-faceted rehab approach. Firstly, in the acute phase, it’s essential to unload the affected area, employing methods like ice application, relative rest, and anti-inflammatories to reduce swelling. Additionally, incorporating gentle massage techniques can help alleviate some of the swelling.

Furthermore, we recommend introducing joint mobility work, both passively and actively. However, it’s vital to exercise caution during this phase, especially avoiding any movements that involve extending the affected joint, as this might exacerbate the issue.

As part of this joint mobility work, climbers can isolate the specific joint, typically with the thumb and index finger of their opposite hand, and perform controlled back-and-forth movements to maintain some level of active mobility while also focusing on the joint itself. This aids in keeping the joint lubricated and helps prevent further stiffness.

Can you explain why the ring finger is different from the pointer finger, and what predisposing factors should be considered?

Certainly. The distinction between the ring finger and the pointer finger lies in their anatomy and the range of motion they offer. The ring finger, due to its structure and location, possesses less mobility compared to the pointer finger, particularly when attempting to hyperextend it or push it backward.

In terms of predisposing factors, climbers should be aware that DIP capsulitis is more likely to affect newer climbers who rely heavily on the full crimp position without fully understanding the mechanics involved. These individuals may not have started hangboarding or focusing on climbing technique, which can increase the risk of this injury.

Additionally, those who rapidly intensify their climbing routines or engage in routes that require extensive use of the full crimp position, particularly advanced climbers, are also susceptible to developing this type of injury.

Discuss the importance of long-term injury reduction and incorporating a dynamic warmup into climbers’ routines.

Long-term injury reduction is a critical aspect of climbers’ training and should be integrated into their routines. Following the acute phase of DIP capsulitis rehabilitation, climbers should focus on preventing future injuries.

One essential component of this is incorporating a comprehensive dynamic warmup into their climbing routine. A dynamic warmup serves to enhance blood circulation, prepare the muscles and joints for activity, and optimize overall performance.

While static stretching has been traditionally popular, recent research suggests that it may not effectively warm up the muscles or contribute significantly to injury prevention. Thus, it is recommended to perform static stretching separate from climbing activity.

For climbers, a dynamic warmup should be specific to the demands of climbing, emphasizing finger and wrist extensor strength to create a balanced grip. This can involve exercises like tendon glides, ball squeezes, and rice bucket drills, which target finger and wrist extensors, enhancing the overall strength and stability of the hand.

The dynamic warmup should ideally be integrated into the climber’s routine before exercise, hangboarding, or climbing sessions. It’s worth noting that a dynamic warmup can also become part of regular maintenance, ensuring that climbers are adequately prepared and resilient to the demands of their sport.

Sure, here’s the Q&A format with Jared’s questions shortened to one sentence and Steve’s responses lengthened:

Pinch grip variations and wrist extension exercises—could you discuss these in detail?

Certainly, let’s dive into pinch grip variations and wrist extension exercises. Pinch grip variations can be particularly useful for strengthening finger flexors and extensors, but they may put some compression on the outside of the elbow. For wrist extension exercises, they involve having your forearm resting on a bench or similar support with a dumbbell in your hand, allowing controlled wrist movement. This exercise can be especially helpful for climbers dealing with lateral elbow pain or seeking to improve wrist strength and stability.

What are some key considerations when performing wrist extension exercises, especially for climbers dealing with lateral elbow pain?

It’s crucial to maintain the right elbow position, typically bent at around 30 to 60 degrees from straight, to minimize compression on the outer elbow tendon. Start with a weight that challenges you but doesn’t strain excessively, and perform three to four sets of six to 12 repetitions. This exercise can be done using a dumbbell or a kettlebell, but be cautious about using very heavy weights, as it may lead to wrist issues.

Can you explain the differences between isotonic and isometric exercises for finger and wrist extensors?

Certainly, let’s explore the distinctions between isotonic and isometric exercises. Isotonic exercises involve moving a weight, such as a dumbbell, and can be beneficial for building strength and endurance. Isometric exercises, on the other hand, entail pushing or pulling against an immovable force, which can be a valuable approach for rehabilitating or strengthening specific muscle groups without joint motion. There are two types of isometric exercises—yielding and overcoming isometrics. Yielding isometrics involve maintaining a static position against resistance, whereas overcoming isometrics require attempting to move an immovable object. Both types have their place in a climbing-specific training regimen, depending on individual goals and needs.

How should climbers program these exercises effectively, considering factors like tendon density, muscle hypertrophy, and symptom management?

Effective programming depends on individual goals and symptom response. If you’re targeting strength and stiffness, aim for a total time under tension of 30 to 90 seconds, with higher-intensity, shorter-duration holds. For tendon density or muscle hypertrophy, consider extending the time under tension to 80 to 150 seconds per set and incorporating longer holds to reduce intensity. It’s essential to monitor your symptoms and adapt your program accordingly, avoiding overloading the affected area.

You mentioned pinch grip variations—can you elaborate on these, including potential benefits and precautions for climbers?

Certainly, let’s delve deeper into pinch grip variations. These exercises can be a more advanced way to load your finger and wrist extensors. By creating different pinch grip setups, such as using two by fours, knob holds, or even upside-down kettlebells, climbers can target finger flexors, extensors, and wrist muscles while keeping the joint relatively unloaded. However, climbers should be mindful of potential overuse injuries, so it’s advisable to cycle through different variations to prevent strain or injury.

How can climbers adjust their training to avoid overloading their fingers and wrists, especially when dealing with finger pain or discomfort?

When dealing with finger pain or discomfort, it’s essential to find a balance between maintaining strength and avoiding overloading. Climbers can modify their training by reducing volume, intensity, or both, as needed to minimize strain on the affected area. Additionally, monitoring symptoms and using pain as a guide can help climbers determine when to back off or make further adjustments in their training routine.

Could you share insights on incorporating hangboard training for climbers dealing with DIP synovitis capsulitis?

Certainly, hangboard training can be a valuable tool for climbers managing DIP synovitis capsulitis. It’s essential not to completely stop climbing but rather modify your approach. Consider using open-hand positions, larger holds, or slopers to reduce stress on the affected area. Duration and intensity can be adjusted based on your pain threshold and individual needs. However, if you struggle with longer hangs due to other body limitations, consider consulting a physical therapist for personalized guidance.

Returning to climbing after dealing with this condition can be challenging—what recommendations do you have for climbers seeking a safe return?

Returning to climbing should be gradual and considerate of your body’s response. Start by climbing slabs, jugs, or slopers to minimize stress on the affected area. Ensure that your symptoms remain below a four out of ten on the pain scale and avoid exacerbating pain the next day. Evan Ingersen’s article and podcast on returning to climbing offer excellent guidance and should be a valuable resource for climbers making a safe return.

Any final thoughts or advice for climbers dealing with DIP synovitis capsulitis?

In closing, I’d emphasize the importance of early intervention and avoiding prolonged issues. Don’t completely avoid finger flexion positions but do take some time to offload the affected joint initially. It’s crucial to make necessary modifications in your climbing technique to manage symptoms effectively while maintaining strength and resiliency for future climbing challenges. If you have questions or need guidance, please feel free to reach out for support and individualized recommendations.
