PADEL SHOULDERIMPINGEMENT: CAUSES, RECOVERY & RETURN TO COURT

The Anatomy Behind the Pain

Your shoulder is a ball-and-socket joint with an extraordinary range of motion — which is exactly why it’s so vulnerable. Between the top of your upper arm bone (humerus) and the bony roof of your shoulder (the acromion) sits a narrow corridor called the subacromial space. Packed into that space are your supraspinatus tendon (part of the rotator cuff), the subacromial bursa, and the long head of your biceps tendon.

When you raise your arm — especially overhead — this space compresses naturally. In a healthy shoulder with strong, well-balanced muscles, there’s enough room. But when something goes wrong with the mechanics, the soft tissues inside that space get caught, pinched, or irritated every time your arm lifts. That’s impingement. Repeated compression causes inflammation, swelling, and eventually a painful cycle that gets worse with every overhead stroke you play.

Understanding this anatomy matters because it tells you why strengthening the right muscles is the actual fix — not just resting until the pain goes away.

Types of Shoulder Impingement

Clinicians typically split shoulder impingement into two categories: primary and secondary. Primary impingement is a structural problem — the acromion itself has a shape (Type II or Type III) that leaves less room in the subacromial space. Secondary impingement — which is far more common in padel players — is a functional problem caused by poor muscle balance, scapular dyskinesis, or joint instability that allows the humeral head to ride too high during movement.

There’s also internal impingement, which is increasingly recognised in overhead sports athletes. Here the rotator cuff gets pinched between the humeral head and the glenoid labrum at the back of the shoulder, often during the late cocking or early acceleration phase of an overhead stroke. Internal impingement tends to produce pain at the back of the shoulder rather than the classic anterior or lateral pain of subacromial impingement.

Most padel players will experience the subacromial (secondary) variety, but both types respond well to targeted physiotherapy.

Why Padel Is a High-Risk Sport for This Injury

Unlike tennis, padel is played in an enclosed glass court where walls are legitimate playing surfaces. That changes everything about stroke mechanics. The bandeja — padel’s signature defensive lob — demands a highly specific overhead arm path repeated dozens of times per match. The vibora, the rulo, the smash off the back wall: every one of these strokes loads the subacromial space significantly.

Research into overhead racket sports consistently shows that cumulative mechanical load, rather than a single traumatic event, is the primary driver of tendon pathology. A padel player completing 80–120 overhead strokes per match across three to four sessions per week is accumulating serious repetitive stress on the shoulder complex. Add in inadequate warm-up, insufficient rotator cuff strength, and the natural competitive urge to hit harder, and the conditions for impingement become almost inevitable without proactive management.

The Overhead Stroke Mechanics Problem

The supraspinatus tendon passes through its narrowest point in the subacromial space when the arm is elevated between 60 and 120 degrees — a zone physios call the painful arc. Every bandeja, every smash, every volley at net takes your arm through exactly this range. In an average padel match, a club player might complete this movement 200–300 times when you account for serves, overhead shots, and high defensive returns.

Now multiply that across a week of training. The tendon doesn’t have the same blood supply as muscle tissue, which means it heals slowly. When mechanical load outpaces the tendon’s capacity to recover, microscopic damage accumulates faster than the body can repair it. What starts as mild post-match stiffness becomes sharp pain during play, then pain at rest, then the inability to raise your arm past shoulder height. This progression is not inevitable — but it is predictable if you don’t address it early.

Rotator Cuff Weakness and Muscle Imbalance

The four muscles of the rotator cuff — supraspinatus, infraspinatus, teres minor, and subscapularis — act as dynamic stabilisers that keep the ball centred in the socket during movement. When these muscles are weak or fatigued, the larger prime movers like the deltoid and upper trapezius take over. This creates a pattern where the humeral head migrates superiorly during arm elevation, eating directly into the subacromial space.

In padel specifically, the dominant hitting arm is chronically over-developed in the internal rotators (subscapularis, pectorals, lats) relative to the external rotators (infraspinatus, teres minor). This internal rotation dominance is a direct mechanical risk factor for impingement. Players who don’t incorporate external rotation and posterior cuff strengthening into their training — and most recreational players don’t — are progressively building a weaker, more impingement-prone shoulder with every match they play.

Scapular Control, Posture, and Training Load

The scapula (shoulder blade) has to rotate upward precisely as your arm rises overhead. This upward rotation opens up the subacromial space and keeps the humeral head properly positioned. If the muscles controlling scapular movement — particularly the lower and middle trapezius and serratus anterior — are weak, the scapula tips forward and downward, collapsing the subacromial space and dramatically increasing impingement risk.

Prolonged sitting, desk work, and poor gym posture all contribute to the rounded shoulder, forward head posture pattern that inhibits scapular upward rotation. Many of our players are arriving on court already in a compromised position before they hit their first ball. Add to this the common mistake of dramatically increasing training volume too quickly — ramping from twice a week to daily play over a tournament period — and you have a perfect storm of mechanical overload with inadequate recovery time.

Recognising the Symptoms

The hallmark symptom of subacromial shoulder impingement is a painful arc — pain that begins when you lift your arm to around 60 degrees, peaks between 60 and 120 degrees, and then often eases as you raise the arm above your head. This pattern is highly specific to impingement and distinguishes it from a full rotator cuff tear, where pain and weakness persist throughout the range of motion.

You’ll typically notice pain at the front or outer side of the shoulder, sometimes radiating into the upper arm. Night pain is extremely common — many players report being woken by the shoulder aching when they roll onto it. There’s often stiffness first thing in the morning that eases with movement. In the acute phase, even reaching across your body (like putting on a seatbelt) or reaching behind your back (fastening a bra, tucking in a shirt) becomes genuinely painful. The key diagnostic question to ask yourself: is it worse with overhead activity and better with rest? If yes, impingement is the most likely culprit.

Clinical Tests and When to Seek Professional Help

A qualified physiotherapist or sports medicine doctor can confirm shoulder impingement through a combination of clinical tests. The Neer test — arm raised in internal rotation — and the Hawkins-Kennedy test — arm brought to 90 degrees then internally rotated — are the most widely used provocative tests. A positive result on both has good sensitivity for subacromial impingement. Empty Can and Full Can tests assess the supraspinatus specifically, while the external rotation lag sign helps screen for larger rotator cuff involvement.

You should seek professional assessment if: pain has lasted more than two weeks without improvement; you have significant weakness in the arm rather than just pain; you heard or felt a pop at the time of onset; pain is constant rather than activity-related; or you’re over 40 and have had previous shoulder issues. These features can indicate a partial or full rotator cuff tear, SLAP lesion, or AC joint pathology that requires imaging (ultrasound or MRI) to differentiate.

Imaging: Do You Need a Scan?

Most straightforward cases of shoulder impingement do not require imaging to begin rehabilitation. A clinical assessment by an experienced physiotherapist is sufficient to guide early treatment. However, imaging becomes valuable when the diagnosis is uncertain, when there’s been no meaningful improvement after 6–8 weeks of good quality physiotherapy, or when clinical tests suggest a significant rotator cuff tear.

Ultrasound is the most accessible and cost-effective option for assessing tendon integrity and bursal swelling. MRI provides superior soft tissue detail and is preferred when labral pathology, internal impingement, or significant cuff tearing is suspected. Plain X-ray is useful for identifying bony abnormalities (Type III acromion, calcific deposits, AC joint changes) but tells you little about the soft tissue structures. Don’t self-diagnose from a scan report alone — imaging findings need to be interpreted alongside your clinical presentation by someone who understands overhead sport biomechanics.

Phase 1: Acute Management (Weeks 1–2)

In the first one to two weeks, the priority is reducing pain and inflammation without creating dependency on passive treatments. Relative rest is the keyword here — relative, not complete. Complete immobilisation is counterproductive because tendons need mechanical load to heal. Instead, avoid the specific aggravating overhead movements while maintaining gentle range of motion.

Ice (15–20 minutes post-activity, three to four times daily) is effective for acute pain management. NSAIDs like ibuprofen, if you can tolerate them and have no contraindications, can help break the pain-inflammation cycle in the short term — but they’re a pain management tool, not a cure. Avoid cortisone injections as a first-line treatment; evidence suggests they provide short-term relief but may impair tendon healing if used too early or too frequently. Sleep positioning matters too: use a pillow under the affected arm when sleeping on your back, or sleep on the unaffected side with a pillow between your arms.

Phase 2: Rotator Cuff Strengthening (Weeks 2–6)

This is the most important phase, and the one most players rush through or skip entirely. The goal is to rebuild the rotator cuff’s capacity to dynamically stabilise the humeral head during movement. Start with low-load, high-repetition exercises that don’t provoke pain above a 3 out of 10 on the pain scale. Theraband external rotation, side-lying external rotation, and prone Y-T-W exercises targeting the lower trapezius are your foundation.

Progress to the Empty Can exercise (arm raised to 90 degrees in the scapular plane, thumb pointing down) and then Full Can (thumb pointing up) as pain allows. Incorporate scapular setting exercises — conscious protraction and retraction, depression — to rebuild proper scapular control before advancing to more complex loading. Side-lying internal and external rotation with a dumbbell, starting at 1–2 kg, forms the cornerstone of cuff rebuilding. Every exercise should be pain-controlled, performed slowly, and completed with perfect form. Three sets of 15–20 repetitions daily is a reasonable starting point.

Phase 3: Sport-Specific Loading and Overhead Reintroduction (Weeks 6–12)

Once you can perform shoulder external rotation against resistance without pain, and demonstrate good scapular control during overhead movements, you’re ready to begin sport-specific loading. This phase bridges the gap between clinical rehab and padel-specific demands. Start with overhead pressing movements (dumbbell press, cable overhead press) at comfortable loads. Medicine ball wall throws at progressively higher angles train the deceleration patterns that protect the shoulder during follow-through.

Proprioceptive training — exercises on unstable surfaces, single-arm balance work — rebuilds the joint position sense that tends to degrade after any shoulder injury. Introduce hitting mechanics off-court first: shadow strokes at 50% intensity, focusing on a smooth, controlled arm path rather than power. Video your shadow stroke from behind if possible — scapular winging or premature trunk rotation are common compensatory patterns that need correcting before you return to live ball hitting. Gradual plyometric loading of the shoulder (progressive throwing programs are well-evidenced for this) helps prepare the tendon for the rapid loading rates it will face on court.

Objective Criteria Before You Step Back on Court

Too many padel players use pain as their only return-to-play criterion. Pain-free at rest does not mean ready to play. You need to meet specific functional benchmarks before resuming overhead sport. First, full pain-free passive and active range of motion in all planes — flexion, abduction, external and internal rotation. Second, rotator cuff strength within 80% of the unaffected side (your physio can assess this with a handheld dynamometer or resisted movement tests). Third, the ability to perform 10 pain-free repetitions of an overhead pressing movement at 60% of your body weight.

Scapular control is the final check: can you perform a wall slide (arms raised overhead while maintaining contact between forearm and wall) for 3 sets of 15 reps without pain or significant winging of the shoulder blade? If yes, you’re mechanically ready to begin a phased return to court. If any of these criteria are absent, you are not ready — regardless of how good the shoulder feels during daily activities.

A Progressive Return-to-Court Protocol

Week 1 back on court: groundstrokes only, 20–30 minutes per session, no overhead strokes at all. Focus on letting the shoulder warm into movement rather than hitting at competitive intensity. Week 2: introduce chest-height volleys and low overheads (below head level) at 60% intensity. If no pain during or after sessions, continue. Week 3: full overhead work at 70% effort — bandejas but no full smashes. Watch your post-match soreness; it should resolve within 24 hours. Week 4: return to full practice but maintain a maximum of two sessions per week with a full rest day between each.

Weeks 5–6: return to match play with the explicit agreement that you will manage your overhead volume. Many players find that making conscious tactical choices — taking fewer smashes and using more lobs — allows them to return to competition faster while still protecting the healing tissue. Full return to unrestricted competitive play typically occurs between weeks 8 and 12 for moderate impingement cases.

Managing Setbacks During Recovery

A flare-up during return to play is common and does not mean you’ve failed or re-injured yourself. Increased soreness for 12–24 hours after a session within normal limits. Pain that persists beyond 48 hours, or that worsens with each subsequent session, is a signal to step back one phase and rebuild for another week before progressing again. This two-steps-forward, one-step-back pattern is frustrating but entirely normal in tendon rehabilitation.

Keep a simple training diary during your return: note the session duration, overhead shot volume (roughly), pain during, pain immediately after, and pain the next morning. This data is invaluable for identifying the tipping point where load exceeds your current tolerance. It also gives your physiotherapist objective information to guide progression decisions. The players who recover fastest are almost always the ones who take the monitoring seriously rather than relying on gut feel alone.

The Non-Negotiable Warm-Up

A targeted shoulder warm-up before every padel session is the single highest-return injury prevention investment you can make. It doesn’t need to be long — 8 to 10 minutes is sufficient — but it needs to be specific. Dynamic arm circles, cross-body arm swings, and thoracic spine rotations prepare the joint’s range of motion. Banded external rotation and face pulls activate the posterior cuff and lower trapezius before they’re needed on court. A set of scapular wall slides ensures scapular upward rotation is online before you start hitting overheads.

We recommend ending the warm-up with 10–15 shadow overhead strokes at 40–50% speed, consciously rehearsing the arm path you want to use during play. This neuromuscular priming reduces the chance of compensatory movement patterns sneaking in when you’re focused on the ball rather than your mechanics. Players who skip the warm-up because they’re running late are the ones filling our injury guides — we’ve seen it too many times.

Strength Training Off Court

You cannot out-warm-up a weak rotator cuff. Two sessions per week of targeted shoulder strengthening, performed year-round, is what separates players who stay healthy from those who cycle through repeated injuries. The essential exercises are: cable external rotation (both at 0 and 90 degrees of abduction), prone Y-T-W for scapular stability, face pulls for posterior cuff and rear deltoid, and Pallof presses for rotational core stability that supports the kinetic chain up through the shoulder.

Don’t neglect the posterior chain: weak thoracic extensors and tight pectorals create the rounded shoulder posture that directly contributes to subacromial crowding. Seated cable rows, band pull-aparts, and chest stretching should be standard components of any padel player’s gym routine. For players over 40, evidence supports slightly higher training volumes for tendon maintenance — three resistance sessions per week with adequate protein intake (1.6–2g per kg of body weight daily) significantly improves tendon resilience.

Technique Adjustments That Reduce Overhead Stress

Biomechanical coaching changes can meaningfully reduce shoulder load without compromising shot quality. The most impactful adjustment for impingement-prone players is the bandeja arm path: many recreational players swing with excessive internal rotation and a dropped elbow, creating a mechanical position that maximally narrows the subacromial space. A more externally rotated, elbow-high position throughout the swing reduces impingement risk significantly.

Generating more power from trunk rotation rather than arm speed reduces the absolute load on the shoulder joint. Work with a padel coach specifically on the sequencing of your kinetic chain — legs, hips, trunk, shoulder, arm — so the shoulder is the final link in a powerful chain rather than the primary power source. Consider the role of grip: excessive grip tension travels up the kinetic chain and creates unwanted stiffness through the elbow and shoulder. A lighter grip (5 out of 10 tension rather than 8–9) allows the shoulder to decelerate more smoothly after ball contact.
