Shoulder Instability and Dislocation Rehab | Southampton Physio
How long does shoulder instability take to heal?
Recovery from shoulder instability depends on severity and treatment. Physiotherapy can restore strength and stability without surgery.
Understanding Shoulder Instability and Dislocation
A shoulder dislocation can be a shock. One moment you are lifting, reaching or playing sport – the next, your shoulder is out of place and you’re left wondering if it will ever feel stable again. For some people, this only happens once. For others, the joint keeps “popping out”, leading to repeated dislocations or a constant feeling that the shoulder is about to slip. This is known as shoulder instability.
At Southampton Physio, we see this problem in a wide range of people: from rugby players and climbers to those with hypermobility or everyday workers who had a sudden fall. The good news is that most people can recover function and confidence with the right rehabilitation. While surgery has its place, evidence shows that many cases respond well to structured physiotherapy, helping you rebuild strength and stability without invasive treatment.
Causes and Risk Factors
Your shoulder is the most mobile joint in your body – and that freedom of movement comes with a trade-off: it is also the most unstable. Instability occurs when the structures that normally keep the shoulder in place – muscles, tendons, ligaments and the joint capsule – are stretched, weakened or damaged.
Common causes include:
- Trauma: A sudden impact, such as a fall on an outstretched arm or a rugby tackle, can force the joint out of its socket.
- Sports demands: Repetitive overhead movements in swimming, tennis or weightlifting place extra strain on the joint.
- Hypermobility: Some people are naturally more flexible, meaning the ligaments do not provide enough restraint.
- Previous injury: Once a shoulder has dislocated, the risk of it happening again increases, especially in younger athletes.
Who is most at risk?
Research shows that recurrence is most likely in people under 30, particularly men involved in contact or overhead sports. For those in this group, each dislocation can increase the chance of further episodes. That’s why early high-quality rehab is essential: it reduces the risk of repeat injuries and helps you return to sport with confidence.
For older adults, instability can also result from gradual changes in the joint or rotator cuff injuries. These cases may present differently but still benefit from careful strengthening and guided rehabilitation.
Symptoms and When to Seek Help
Shoulder instability doesn’t always look the same for everyone. Some people experience a dramatic dislocation where the joint visibly shifts out of place. Others feel a recurring “slip”, “pop” or sense that the shoulder might give way.
Typical symptoms include:
Typical symptoms include:
- Pain, especially with overhead or outward arm movements
- A feeling of looseness or “dead arm” after activity
- Recurrent dislocations or partial dislocations (subluxations)
- Weakness and reduced confidence in the shoulder
- Weakness and reduced confidence in the shoulder
Red flags after a dislocation include:
- Numbness, tingling or weakness in the arm or hand
- Loss of pulse or obvious circulation changes
- Severe, unrelenting pain or deformity that doesn’t reduce with standard care
- Inability to move the shoulder after injury
If any of these occur, it’s important to seek immediate medical help. Otherwise, beginning physiotherapy as soon as it is safe can make a big difference to recovery.
Physiotherapy Treatment
Physiotherapy is the first-line treatment for most people after a shoulder dislocation. The goal is not just to reduce pain but to restore strength, control and confidence in the joint so it can cope with everyday life and sport.
Early management usually includes a short period of rest or immobilisation in a sling, often for two to three weeks, depending on the injury. After that, the focus shifts to gentle movement and progressive loading.
A typical rehabilitation programme may include:
- Range of motion exercises: Restoring comfortable movement without forcing the joint.
- Strengthening: Targeting the rotator cuff and scapular muscles to support the joint.
- Proprioception and control drills: Training your body to recognise joint position and react quickly to prevent slips.
- Sport- or task-specific conditioning: Preparing you for the demands of work, gym training or your chosen sport.
Manual therapy techniques may help in the short term to ease pain and stiffness, but the long-term gains come from exercise. Education is also key: understanding your risks, learning how to pace activity and gradually exposing the shoulder to greater loads is what protects against repeat episodes.
Every rehab plan is personalised. At Southampton Physio, your clinician will assess not only the shoulder but also wider factors like sleep, stress and training habits, as these can influence pain and recovery. For many people, physiotherapy alone is enough to regain stability. For others, it also provides a solid foundation if surgery later becomes necessary.
What to Expect at Southampton Physio
Your first appointment starts with a detailed assessment: we look at your shoulder’s range of motion, muscle strength and stability tests but also at your lifestyle, training history and future goals. We always screen for red flags and decide if onward referral is needed.
From there, you’ll receive a tailored programme. Early sessions often focus on safe mobility and building baseline strength. As you improve, we progress into stability drills, dynamic loading and – if relevant – sport-specific exercises. You’ll also get advice on managing everyday activities, pacing your return to work and practical tips to stop the shoulder “slipping” in daily life.
Most people notice improvements in confidence and control within a few weeks. While timelines vary, many regain daily function within 12 weeks, with sport often taking longer depending on the demands.
Surgery vs Rehab
For most people, physiotherapy is the best starting point. It builds shoulder stability, reduces pain and can prevent repeat dislocations. However, there are times when surgery is appropriate – particularly for younger athletes who play contact sports and are at high risk of recurrence.
Research suggests that surgery can reduce redislocation rates in some cases, but it is not a guarantee. Rehabilitation is still required after an operation, and the decision is best made through shared discussion between you, your clinician and a surgeon if needed.
At Southampton Physio, our role is to guide you through this process: to help you achieve the best possible results without surgery if that’s realistic, and to prepare you well if surgery becomes the right option.
Return to Sport and Daily Life
A common question is when it’s safe to return to sport. The honest answer: it depends. Most people regain everyday comfort by around 12 weeks, but full return to contact or overhead sports often takes longer.
We use criteria-based progression rather than fixed timelines. That means looking at your strength, control, confidence and ability to handle sport-specific drills before signing you off. This approach reduces the risk of re-injury and builds trust in your body again.
For non-athletes, return to work and everyday tasks follow the same principle: graded exposure, building resilience step by step.
Special Considerations: Hypermobility and Chronic Instability
Some people have naturally loose joints or conditions such as Ehlers-Danlos syndrome. For them, instability may not be caused by trauma but by lax ligaments and repetitive strain.
Physiotherapy still plays a central role. We emphasise strengthening, stability drills and lifestyle strategies to support long-term management. Bracing or taping can be used for specific tasks, but the key remains progressive exercise and confidence-building.
For chronic cases where the shoulder has slipped repeatedly, rehab is often a long-term process. Our aim is not only to restore control but to equip you with the tools to self-manage for life.
Frequently Asked Questions (FAQs)
Should I wear a sling after dislocation, and for how long?
Usually only for a short period (often two to three weeks). Prolonged immobilisation is not recommended.
What happens if shoulder instability is left untreated?
It can lead to repeat dislocations, reduced strength and longer-term joint changes. Early rehab lowers this risk.
Can physiotherapy fix recurrent shoulder dislocations?
Yes, for many people. A structured programme improves stability and reduces recurrence.
Is it safe to return to sport after shoulder dislocation?
Yes – once you meet strength, control and confidence criteria. Rushing back too soon increases the chance of relapse.
Do I need surgery for shoulder instability?
Only if high-quality rehab has not resolved your symptoms or if you are in a high-risk group such as young contact athletes.
