Shoulder Instability and Dislocations: Rehabilitation and Prevention

by admin | Apr 3, 2025 | Guides

Introduction

The shoulder is the most mobile joint in the human body, and the most unstable. Its exceptional range of motion comes at the cost of structural security: unlike the hip, where a deep bony socket provides inherent stability, the shoulder's glenoid is shallow, providing minimal bony constraint. Dynamic stability depends entirely on the rotator cuff muscles, scapular stabilisers, and a complex of ligaments and labrum. When these fail, either from a traumatic dislocation or progressive functional instability, the joint's vulnerability to recurrence is high. Understanding the anatomy and the rehabilitation requirements is essential because without structured rehabilitation, anterior shoulder dislocation has an extremely high recurrence rate, approaching 90% in young active individuals.

Whether you are dealing with a recent flare-up or something that has nagged you for years, understanding why your body hurts is the most important first step. This guide draws on the latest pain science, physiotherapy research, and practical coaching wisdom meticulously validated and referenced to give you peace of mind.

Understanding the Anatomy

The glenohumeral (shoulder) joint is formed by the large humeral head and the small, shallow glenoid fossa of the scapula. The glenoid labrum, a fibrocartilaginous ring deepening the socket, and the glenohumeral ligaments (superior, middle, and inferior) provide passive stability. The rotator cuff provides dynamic compression (drawing the humeral head into the glenoid), and the scapular muscles (serratus anterior, lower and middle trapezius) control the position of the glenoid fossa beneath the humeral head. Anterior dislocation, by far the most common, occurs when the arm is forced into abduction and external rotation, driving the humeral head anteriorly past the anterior labrum and inferior glenohumeral ligament (IGHL). This often creates a Bankart lesion (labral tear) and Hill-Sachs lesion (humeral head impression fracture).

Key structures involved: Subscapularis (primary anterior stabiliser), Infraspinatus and teres minor (posterior stabilisers and external rotators), Serratus anterior (glenoid fossa positioning), Lower and middle trapezius (scapular control), Deltoid (functional force couple).

Why Does It Hurt? Root Causes

Modern pain science reminds us that pain is your nervous system's threat response, not simply a damage signal. That said, there are real, identifiable drivers.

1. Traumatic Anterior Dislocation

The most common mechanism, typically a fall on an outstretched hand or a forced abduction/external rotation. Creates the anatomical lesions that predispose to recurrence.

2. Multidirectional Instability (MDI)

A constitutional laxity of the glenohumeral joint capsule and ligaments producing instability in multiple directions, common in hypermobile individuals, gymnasts, and swimmers. Treated with strengthening rather than surgery in most cases.

3. Posterior Instability

Less common, occurring from a posterior force on the flexed, adducted arm, seen in rugby props, powerlifters, and epileptic seizure. More subtle presentation than anterior dislocation.

4. Functional Instability from Muscle Imbalance

Without adequate rotator cuff and scapular muscle function, the shoulder joint can develop progressive subluxation and instability even without acute trauma.

How Massage Helps

Post-dislocation massage targets the periscapular musculature and posterior shoulder structures rather than the anterior joint structures (which are acutely injured). Massage of the posterior rotator cuff (infraspinatus, teres minor) maintains tissue quality while anterior healing occurs. As rehabilitation progresses, the subscapularis is addressed to restore its critical anterior stabilising function. Posterior capsular tightness, which develops as an adaptive response to anterior instability, is addressed with gentle soft tissue release to prevent the secondary impingement and GIRD (glenohumeral internal rotation deficit) that develops if uncorrected.

Beyond specific mechanical effects, massage floods the nervous system with safe, rich sensory input, downregulating the threat response and creating conditions in which healing becomes easier.

Stretches to Try

Consistency matters far more than intensity. Gentle, daily stretching with calm breathing reduces perceived tightness and signals safety to the nervous system.

Cross-Body Stretch (Posterior Capsule)

Bring the arm across the body at shoulder height. Use the other hand to gently deepen the stretch. Hold 30 seconds per side. Benefit: Addresses the posterior capsular tightness that commonly develops after anterior instability. GIRD (glenohumeral internal rotation deficit) increases anterior instability risk if uncorrected.

Doorway Pectoral Stretch

Stand in a doorway, arm at 90 degrees. Gently lean forward. Hold 30 seconds. Note: avoid range that produced the dislocation until strength is established. Benefit: Maintains pectoral and anterior shoulder flexibility, important for long-term shoulder health after instability.

Thoracic Rotation and Extension

Thoracic mobility routine, foam roller extension and seated rotation. Benefit: Poor thoracic mobility is a significant contributor to shoulder instability by limiting scapular range of motion.

Strengthening Exercises

Loading tissues progressively tells your nervous system they are capable and resilient.

Scapular Stabilisation Programme. Phase 1

Prone Y-T-W exercises, wall slides, and scapular retractions. Before any rotator cuff loading. Benefit: The scapular stabilisers must be established before rotator cuff loading, a scapula that cannot position the glenoid correctly undermines all rotator cuff training.

External Rotation Strengthening

Side-lying external rotation with progressive weight. 3 sets of 15. Benefit: The infraspinatus and teres minor are the most important muscles for posterior restraint of the humeral head, their strength directly reduces anterior instability.

Proprioceptive Training. Rhythmic Stabilisation

Therapist or partner applies random directional perturbations to the shoulder while the patient maintains position. Progress to unstable surface and closed-chain push-up variations. Benefit: Proprioceptive training is an essential component of shoulder stability rehabilitation, the nervous system must be retrained to protect the joint with the same automaticity that was lost after dislocation.

Practical Self-Care

• After first dislocation: structured rehabilitation with a physiotherapist is non-optional for young, active individuals, the recurrence rate without rehabilitation is around 90%.
• Avoid the 90-degree abduction plus external rotation position during rehabilitation, this is the position of maximum instability.
• Return to contact sport should require clinical testing of rotator cuff strength, not just absence of pain.
• Surgical stabilisation (Bankart repair) should be considered after two or more dislocations in young, active individuals, or after a first dislocation with significant labral tear.
• Taping or a functional brace can reduce dislocation risk during early return to sport.

When to See a Professional

• First dislocation requiring closed reduction in A and E, imaging for associated fractures and formal physiotherapy referral.
• Recurrent dislocation, surgical assessment.
• Nerve deficit after dislocation, particularly axillary nerve (deltoid weakness), urgent assessment.
• Vascular symptoms after shoulder injury, emergent vascular assessment.

A qualified physiotherapist, sports therapist, or massage therapist can identify the specific drivers of your pain.

Disc Herniation: What It Really Means and How to Recover

by admin | Apr 3, 2025 | Guides

Introduction

A disc herniation, also called a slipped disc, prolapsed disc, or disc bulge, is one of the most misunderstood diagnoses in musculoskeletal medicine. The terms sound alarming, the imaging looks dramatic, and patients are often told their back will never be the same. The evidence tells a different story. Most disc herniations resolve spontaneously within 12 weeks; many people with dramatic-looking herniations on MRI have no symptoms at all; and the treatments that work are, in most cases, progressive movement and targeted rehabilitation rather than rest or surgery. This guide explains what a disc herniation actually is, why it hurts, and what the evidence says about recovery.

Whether you are dealing with a recent flare-up or something that has nagged you for years, understanding why your body hurts is the most important first step. This guide draws on the latest pain science, physiotherapy research, and practical coaching wisdom meticulously validated and referenced to give you peace of mind.

Understanding the Anatomy

The intervertebral discs sit between adjacent vertebrae throughout the spine. Each disc has two components: the nucleus pulposus, a gel-like core under compression, and the annulus fibrosus, a series of concentric rings of tough fibrocartilage that contain the nucleus. A herniation occurs when the nucleus pushes through a tear in the annulus and protrudes into the spinal canal or neural foramen. This can directly compress nerve roots (causing radiculopathy, the sciatica-like shooting pain, numbness, or weakness that travels into the arm or leg), or it can cause local inflammatory reactions that sensitise nearby structures. The lumbar spine (L4-L5 and L5-S1 being the most common levels) and cervical spine (C5-C6 and C6-C7) are the most commonly affected regions.

Key structures involved: Multifidus (segmental spinal stabiliser, atrophies rapidly with disc pain), Erector spinae, Psoas (often hypertonic in lumbar disc pain, can compress the disc), Transversus abdominis (deep core stabiliser, essential for rehabilitation), Cervical deep flexors (in cervical disc herniation).

Why Does It Hurt? Root Causes

Modern pain science reminds us that pain is your nervous system's threat response, not simply a damage signal. That said, there are real, identifiable drivers.

1. Annular Tear and Nuclear Extrusion

The most common mechanism is cumulative stress on the annular fibres from repeated flexion-compression loading (prolonged sitting, bending and lifting with a rounded spine). Once the annular fibres develop micro-tears, the nucleus can begin to migrate and ultimately extrude through the weakened area.

2. Inflammatory Response

A herniated disc produces an intense local inflammatory response, partly from the disc material itself (which is immunogenic when exposed to the epidural space) and partly from the compression of the nerve root. This inflammation is what causes the acute, severe pain of a fresh disc herniation, and it is what spontaneously resolves over weeks to months.

3. Natural History of Resolution

Large longitudinal studies show that disc herniations resorb spontaneously in the majority of cases, particularly large sequestered fragments, counterintuitively. The immune system recognises the exposed nucleus as foreign and actively resorbs it. This explains why most herniations improve dramatically within 6 to 12 weeks without surgery.

4. Central Sensitisation

Persistent or severe disc pain can establish central sensitisation, the nervous system amplifies pain signals even as the disc pathology resolves. This is why some patients have persistent pain despite resolution on imaging, the pain has become self-sustaining through neurological changes rather than ongoing tissue damage.

How Massage Helps

Massage in the context of disc herniation is primarily palliative in the acute phase and rehabilitative in the subacute and chronic phases. In acute disc herniation with radiculopathy, massage of the paraspinal muscles (erector spinae, multifidus) reduces the protective muscle spasm that contributes to pain and immobility. Trigger point release in the psoas, accessible via anterior abdominal approach in side-lying, reduces the compressive load that the hypertonic psoas places on the lumbar discs. Gluteal massage addresses the referred pain patterns common in L4-L5 and L5-S1 disc pathology. Massage cannot reduce the disc herniation directly, but by reducing the muscle guarding, sensitisation, and psychological distress that accompany disc pain, it is a valuable component of a multimodal approach.

Beyond specific mechanical effects, massage floods the nervous system with safe, rich sensory input, downregulating the threat response and creating conditions in which healing becomes easier.

Stretches to Try

Consistency matters far more than intensity. Gentle, daily stretching with calm breathing reduces perceived tightness and signals safety to the nervous system.

McKenzie Extension Press-Up

Lie face down. Place hands under shoulders. Press the upper body up while keeping the pelvis on the floor. Hold briefly, repeat 10 times. Benefit: Centralises symptoms in lumbar disc herniation (reduces leg pain, even if back pain temporarily increases), the foundation of the McKenzie method for disc rehabilitation.

Nerve Flossing (Neural Mobilisation)

Sit upright. Extend the affected leg, plantarflex the foot, and tilt the chin to the chest. Alternate between this position and full extension with the foot dorsiflexed and head extended. 10 repetitions. Benefit: Mobilises the sciatic nerve within its sheath, reducing the adhesion and sensitisation of the nerve in its canal, reduces radicular symptoms over time.

Hip Flexor Stretch

Kneeling lunge, 30 seconds. Reduces psoas tension and the anterior disc compression that accompanies tight hip flexors in lumbar disc herniation. Benefit: Reduces the compressive load on the anterior lumbar disc that tight hip flexors perpetuate through anterior pelvic tilt.

Strengthening Exercises

Loading tissues progressively tells your nervous system they are capable and resilient.

McGill Bird-Dog

On hands and knees. Extend opposite arm and leg simultaneously, hold 8 to 10 seconds. 3 sets of 5 per side. Benefit: Activates multifidus and transversus abdominis without flexion loading the disc. Stuart McGill's primary stabilisation exercise for disc rehabilitation.

Dead Bug

Lie on back, arms vertical, knees at 90 degrees. Lower one arm and opposite leg towards the floor while keeping the lumbar spine flat. Return and repeat. 3 sets of 10. Benefit: Trains deep core co-activation in an unloaded spinal position, appropriate when loading tolerance is still limited.

Progressive Loading. Deadlift Pattern

As recovery progresses, introduce hip hinge loading with a neutral spine. Start with a Romanian deadlift with minimal weight. Progress load as tolerated. Benefit: Gradual reintroduction of compressive load through the disc is essential for full recovery, avoiding all loading perpetuates weakness and sensitisation.

Practical Self-Care

• Avoid prolonged sitting, stand, walk, or change position every 30 minutes.
• Do not rest completely, gentle walking is one of the most effective treatments for disc herniation.
• Sleep in a position that reduces leg pain, often side-lying with knees slightly bent and a pillow between the knees.
• Apply the McKenzie press-up when leg symptoms are present, if leg pain reduces (centralises), continue; if it worsens, stop and consult a physio.
• Your MRI scan shows structural changes, not your level of ability or your prognosis.

When to See a Professional

• Cauda equina syndrome: loss of bladder or bowel control, saddle anaesthesia, immediate A&E.
• Progressive neurological weakness (foot drop, hand weakness) not improving.
• Severe radiculopathy not responding to conservative treatment after 6 to 8 weeks, consider nerve root injection.
• Red flags: fever, unexplained weight loss, history of cancer alongside back pain.

A qualified physiotherapist, sports therapist, or massage therapist can identify the specific drivers of your pain.

Post-Surgical Rehabilitation: Getting Back to Full Function After Surgery

by admin | Apr 3, 2025 | Guides

Introduction

The success of orthopaedic and soft tissue surgery depends as much on the rehabilitation that follows as on the procedure itself. A technically perfect ACL reconstruction, rotator cuff repair, or hip replacement can produce a poor outcome if rehabilitation is inadequate; conversely, committed rehabilitation can compensate for surgical imperfections. Post-surgical rehabilitation is governed by tissue healing biology, the surgeon creates the conditions for healing, but the patient and their rehabilitation team drive the adaptation. Understanding the phases of healing, the role of loading timing, and how massage complements surgical recovery allows patients to participate actively in their own outcomes.

Whether you are dealing with a recent flare-up or something that has nagged you for years, understanding why your body hurts is the most important first step. This guide draws on the latest pain science, physiotherapy research, and practical coaching wisdom meticulously validated and referenced to give you peace of mind.

Understanding the Anatomy

Tissue healing follows predictable phases: the inflammatory phase (0 to 5 days, dominated by haemostasis and cellular clean-up), the proliferative phase (5 days to 3 weeks, new collagen and tissue formation), and the remodelling phase (3 weeks to 2 years, tissue maturation and organisation). Each phase has specific implications for rehabilitation: early inflammatory phase, protect the repair and manage swelling; proliferative phase, gentle progressive loading to guide collagen alignment; remodelling phase, progressive loading towards functional demands. Rehabilitation that advances too rapidly can disrupt healing; rehabilitation that is too cautious allows the disorganised collagen, muscle atrophy, and neuromuscular deficits that produce poor long-term function.

Key structures involved: Quadriceps (consistently atrophies most rapidly and severely after knee surgery), Rotator cuff (in shoulder surgery, requires graduated progressive loading), Gluteals (hip and lower limb surgery), Core stabilisers (thoracic and lumbar surgery), Local stabilisers of the operated joint.

Why Does It Hurt? Root Causes

Modern pain science reminds us that pain is your nervous system's threat response, not simply a damage signal. That said, there are real, identifiable drivers.

1. Arthrogenic Muscle Inhibition

One of the most significant barriers to post-surgical recovery is arthrogenic muscle inhibition (AMI), the reflexive inhibition of muscles surrounding a joint with pain, swelling, or inflammation. After knee surgery, the quadriceps are inhibited by AMI for weeks to months, even when patients feel ready to train harder. AMI is why quadriceps strength after ACL reconstruction often remains significantly below the contralateral side at 6 months and can persist to 1 to 2 years.

2. The Importance of the Remodelling Phase

Patients and practitioners frequently underestimate the duration of the remodelling phase. Collagen laid down in the proliferative phase is immature and mechanically inferior, it only becomes organised and strong during the remodelling phase with appropriate loading stimulus. This is why return to sport after ACL reconstruction is 9 to 12 months (when collagen has matured) rather than 3 to 4 months (when pain and range of motion have recovered).

3. Psychological Readiness

Fear of re-injury is a significant predictor of poor return-to-sport outcomes after ACL reconstruction and rotator cuff repair. Athletes who are psychologically ready to return to sport have better objective function than those who are psychologically hesitant, even when physical markers are equivalent. Rehabilitation must address psychological readiness alongside physical capacity.

How Massage Helps

Massage has a clearly defined role in post-surgical rehabilitation at each phase. In the immediate post-operative period (with surgeon clearance), effleurage of the limb proximal to the surgical site assists lymphatic drainage of the post-surgical oedema, reducing swelling is one of the primary goals of early rehabilitation. Once wound healing is complete, scar tissue massage (gentle cross-friction and skin mobilisation over the scar and underlying tissue) prevents the development of adherent scar tissue that can limit joint range of motion. In the remodelling phase, massage of the muscles surrounding the operated joint addresses the atrophy, trigger points, and hypertonicity that develop during the period of immobility and restricted loading.

Beyond specific mechanical effects, massage floods the nervous system with safe, rich sensory input, downregulating the threat response and creating conditions in which healing becomes easier.

Stretches to Try

Consistency matters far more than intensity. Gentle, daily stretching with calm breathing reduces perceived tightness and signals safety to the nervous system.

Passive Range of Motion (PROM). Earliest Phase

With the assistance of a therapist or a strap, gently move the operated joint through its available pain-free range. This does not require muscle activation from the operated region. Benefit: Maintains joint mobility and cartilage health during the inflammatory phase when active movement is limited.

Active-Assisted Range of Motion (AAROM)

Use the non-operated limb or gravity to assist the operated limb through its available range. Transition when tolerated. Benefit: Begins recruiting the operated muscles without exceeding the safe loading of the repair.

Progressive End-Range Mobility

As healing permits, work towards regaining full range of motion through active movement. Scar tissue and capsular tightness are the primary restrictions in the remodelling phase. Benefit: Full range of motion is required before strength training is fully effective, range restoration must be prioritised.

Strengthening Exercises

Loading tissues progressively tells your nervous system they are capable and resilient.

Isometric Contractions. Day 1 Post-Op (if cleared)

Isometric quadriceps set (for knee surgery): lie flat, tighten the thigh muscles and push the back of the knee into the bed. Hold 5 seconds, 20 repetitions, hourly. Benefit: Isometrics prevent the worst of arthrogenic muscle inhibition and atrophy without loading the surgical repair, appropriate from day one when cleared.

Straight Leg Raise

Lie on back. Tighten the thigh, then lift the leg to 45 degrees with the knee straight. Lower slowly. 3 sets of 10. Benefit: The first loaded quadriceps exercise after knee surgery, no joint stress, adequate load stimulus to drive early hypertrophy.

Functional Progression

Weight-bearing progresses: non-weight-bearing → toe touch → partial weight-bearing → full weight-bearing as healing allows. Strength exercises progress from isometric to isotonic to functional movements (squat, lunge, hop) with surgeon and physiotherapist guidance. Benefit: Functional progression ensures the tissue is loaded appropriately for its healing stage, too slow delays recovery, too fast risks repair failure.

Practical Self-Care

• Follow your surgeon's and physiotherapist's timeline, it is based on tissue healing biology, not how you feel.
• Pain is not always a reliable guide to loading readiness in post-surgical rehabilitation, your physio's objective markers are more reliable.
• Manage swelling aggressively in the first two weeks, elevation, compression, ice (for pain), and light activity.
• Scar massage (from 6 to 8 weeks post-op, when the wound is closed) significantly improves long-term scar mobility and appearance.
• Set realistic timelines, return to sport after major ligament surgery takes 9 to 12 months.

When to See a Professional

• Signs of surgical site infection: increasing redness, warmth, discharge, fever, contact your surgeon immediately.
• Deep vein thrombosis (DVT) after lower limb surgery: calf swelling, warmth, redness, medical emergency.
• Failure to progress in rehabilitation, seek review from your physiotherapist or surgeon.
• Persistent pain or unexpected limitation, re-imaging may be warranted.

A qualified physiotherapist, sports therapist, or massage therapist can identify the specific drivers of your pain.
