Introduction: Why Rehabilitation Determines Your Outcome
Total knee replacement (TKR) has become one of the most commonly performed orthopaedic procedures worldwide, with over 100,000 procedures carried out annually in England alone (National Joint Registry, 2023). For patients suffering from debilitating osteoarthritis, this surgery offers the promise of reduced pain and restored mobility. However, what many patients—and indeed some healthcare providers—fail to appreciate is that the quality of your rehabilitation programme is arguably more important than the surgical procedure itself in determining your ultimate outcome.
This may seem counterintuitive. After all, surgery is a highly technical procedure performed by skilled orthopaedic surgeons. Yet the evidence is compelling. Artz and colleagues (2015) demonstrated that variations in post-operative rehabilitation explained more of the variance in functional outcomes than surgical factors. Put simply: a good rehabilitation programme can elevate the results of an average surgery, whilst a poor rehabilitation programme can undermine even technically excellent surgical work.
Understanding this shifts the focus from viewing surgery as the endpoint to recognising it as the beginning of a structured recovery journey. This journey typically spans twelve months before patients achieve their optimal outcome—a timeline that often surprises those expecting a quick return to normality. The purpose of this comprehensive guide is to prepare you for that journey, explain each phase of recovery in detail, and demonstrate how advanced rehabilitation technology accelerates your progress.
If you have not yet had your surgery, we strongly recommend reading our article on prehabilitation before knee replacement surgery. The evidence clearly shows that patients who enter surgery stronger and more mobile achieve better post-operative outcomes and recover faster.
Understanding Your Surgery: Total vs Partial Knee Replacement
Total Knee Replacement (TKR)
In a total knee replacement, the surgeon resurfaces all three compartments of the knee joint: the medial compartment (inner side), lateral compartment (outer side), and patellofemoral compartment (behind the kneecap). The damaged cartilage and underlying bone from the femoral condyles (the rounded ends of the thigh bone) and tibial plateau (the flat upper surface of the shin bone) are removed and replaced with metal components. A high-grade polyethylene (plastic) spacer is inserted between these metal surfaces to provide smooth, low-friction articulation. The undersurface of the patella may also be resurfaced with a plastic button.
Total knee replacement is indicated when arthritis affects multiple compartments of the knee, or when there is significant deformity, instability, or inflammatory arthritis. Recovery from TKR typically requires a longer rehabilitation period, with full recovery taking 9-12 months.
Unicompartmental Knee Replacement (UKR/Partial)
Unicompartmental or partial knee replacement is a less invasive option suitable for patients whose arthritis is confined to a single compartment of the knee—most commonly the medial compartment. Only the damaged section is replaced, preserving healthy bone, cartilage, and cruciate ligaments. This results in a more natural-feeling knee, preserved proprioception (joint position sense), and typically faster initial recovery.
However, partial knee replacement is only appropriate for carefully selected patients. Those with inflammatory arthritis, significant deformity, or multicompartmental disease are not candidates. The rehabilitation timeline for UKR is generally accelerated compared to TKR, with patients often walking without aids by 4-6 weeks.
Cemented vs Cementless Fixation
Implant components may be secured to bone using polymethylmethacrylate bone cement (cemented fixation) or may rely on biological ingrowth of bone into a porous-coated surface (cementless or press-fit fixation). Cemented fixation provides immediate stability, allowing earlier weight-bearing. Cementless fixation requires a period of protected weight-bearing whilst bone grows into the implant surface, but may offer superior long-term fixation in younger, more active patients.
Your surgeon will advise which fixation method was used, as this influences early rehabilitation protocols—particularly weight-bearing restrictions in the first few weeks.
What Happens During Surgery: Understanding the Anatomy
Understanding what occurs during your knee replacement surgery helps you appreciate why certain rehabilitation goals matter. During a total knee replacement, the surgeon makes an incision typically 15-20cm long over the front of the knee. The quadriceps tendon and patella are mobilised to expose the joint surfaces.
The surgeon then uses precision cutting guides to remove damaged bone from the distal femur (lower end of thigh bone), creating flat surfaces at specific angles to accept the femoral component. The proximal tibia (upper shin bone) is similarly prepared with a flat cut to accept the tibial baseplate. The undersurface of the patella may be prepared to accept a patellar component.
Trial components are inserted and the knee is tested through its range of motion and stability before final implants are cemented or press-fit into position. The joint is thoroughly irrigated, and layers of tissue are meticulously closed.
This understanding is clinically relevant for several reasons. First, the quadriceps muscle and its tendon are significantly disrupted during surgery, explaining why quadriceps weakness is profound immediately post-operatively. Second, the bone cuts and implant positioning determine the mechanical axis of your new knee—rehabilitation must restore normal movement patterns around this new alignment. Third, the extensive soft tissue dissection creates significant inflammatory response, necessitating structured oedema management throughout early recovery.
The Six Phases of Knee Replacement Rehabilitation
Phase 1: Acute Hospital Phase (Days 0-3)
The acute hospital phase begins immediately after surgery and focuses on four critical priorities: pain management, swelling control, early mobilisation, and prevention of complications.
Pain Management: Adequate pain control is essential not merely for comfort, but because pain inhibits muscle activation and movement. You will receive a combination of regional anaesthesia (often a nerve block), oral analgesics, and anti-inflammatory medications. Multimodal analgesia reduces reliance on opioids and their associated side effects.
Swelling Control: Post-operative oedema is inevitable but must be actively managed. The combination of cryotherapy (ice application), elevation of the limb above heart level, and graduated compression reduces swelling more effectively than any single intervention alone. Many hospitals now use automated cryotherapy devices that combine cooling with intermittent compression.
Early Mobilisation: The days of prolonged bed rest following knee replacement are over. Enhanced Recovery After Surgery (ERAS) protocols have demonstrated that mobilising patients on the day of surgery (Day 0) or the following morning (Day 1) dramatically reduces complications and accelerates recovery (Kehlet and Wilmore, 2008). A physiotherapist will help you stand, take initial steps with a walking frame or crutches, and begin gentle range of motion exercises.
DVT Prevention: Deep vein thrombosis remains a significant risk after lower limb surgery. In addition to anticoagulant medication, you will perform regular ankle pumping exercises (dorsiflexion and plantarflexion) to promote venous return. These exercises should be performed hourly whilst awake.
Initial Quadriceps Activation: Your quadriceps muscle will be profoundly inhibited following surgery—a phenomenon termed arthrogenic muscle inhibition (AMI). Even attempting to contract your quadriceps is important at this stage, even if visible muscle activation is minimal. Static quadriceps contractions (quad sets) with the leg straight begin on Day 1.
Wound Care: Your surgical wound will be covered with a sterile dressing. This is typically changed at 24-48 hours and then left undisturbed unless there are concerns. You will be educated on signs of wound complications requiring medical attention.
Phase 2: Early Recovery Phase (Weeks 1-4)
Upon discharge home, the focus shifts to restoring range of motion, managing persistent swelling, and beginning structured strengthening. This phase requires discipline and consistency—the gains made here establish the foundation for all subsequent rehabilitation.
Range of Motion Goals: Achieving adequate knee flexion (bending) is critical in the early weeks because the window of opportunity is limited. Scar tissue formation begins almost immediately, and the longer the knee remains stiff, the harder it becomes to restore movement. Target ranges are:
- Week 2: 0-90 degrees flexion (the ability to bend your knee to a right angle)
- Week 4: 0-100 degrees flexion
- Full extension (0 degrees, meaning the knee can straighten completely) should be achieved by Week 2
Failure to achieve full extension by Week 4 is concerning and requires immediate intervention to prevent fixed flexion contracture. Heel slides, wall slides, and assisted flexion exercises are performed multiple times daily.
Oedema Management: Swelling peaks around Days 3-5 post-operatively and may take 3-6 months to fully resolve. Continuing elevation, compression (tubular bandage or compression stockings), and cryotherapy remains essential. Excess swelling increases pain, restricts motion, and inhibits muscle activation.
TENS for Pain Modulation: Transcutaneous Electrical Nerve Stimulation (TENS) provides excellent adjunctive pain relief during this phase. Based on the gate control theory of pain (Melzack and Wall, 1965), high-frequency TENS (80-120 Hz) activates large-diameter sensory nerve fibres that inhibit pain signal transmission in the spinal cord. This allows patients to engage more fully in active rehabilitation exercises that would otherwise be limited by pain.
ALCE Neuromuscular Stimulation Initiation: This is perhaps the most critical intervention during early recovery. Arthrogenic muscle inhibition reaches its peak immediately post-operatively—Yoshida and colleagues (2008) documented quadriceps strength deficits of 60-80% in the first weeks following TKR. This inhibition is neurological, not due to muscle damage, meaning patients cannot voluntarily activate their quadriceps no matter how hard they try.
The ALCE (Alternating Longitudinal Contraction and Extension) neuromuscular electrostimulation system bypasses this voluntary inhibition by directly activating motor neurons. During this phase, we begin with lower-intensity protocols targeting Type 1 (slow-twitch) muscle fibres, establishing the neuromuscular pathways that will be progressively intensified in subsequent phases.
Gait Re-education: Walking pattern is almost universally abnormal following TKR. Common compensations include shortened step length, reduced stance time on the operated leg, excessive lateral trunk lean, and inadequate knee flexion during swing phase. Video analysis helps identify these compensations, and specific cueing techniques address each deviation.
Stair Climbing: Stairs are typically introduced in Week 2-3, initially leading with the non-operated leg ascending (good leg to heaven) and the operated leg descending (bad leg to hell). A rail should always be used initially.
Phase 3: Strength Foundation Phase (Weeks 4-8)
With range of motion improving and acute inflammation settling, the emphasis shifts toward building genuine strength—not merely muscle activation, but the ability to generate force. This phase bridges the gap between initial recovery and functional rehabilitation.
Progressive ALCE Protocol: The ALCE programme advances to higher intensities, progressively recruiting Type 2A and ultimately Type 2B fast-twitch muscle fibres. This progression is critical because Type 2B fibres are responsible for explosive power and rapid joint protection during unexpected perturbations. These fibres atrophy rapidly with disuse and pain, and are virtually impossible to recruit voluntarily whilst arthrogenic inhibition persists. The ALCE system uses carrier frequencies up to 1 MHz with burst frequencies of 75-100 Hz specifically to target Type 2B recruitment.
Therapeutic Ultrasound for Tissue Mobility: Residual stiffness at 4-8 weeks often relates to periarticular soft tissue restrictions rather than intra-articular factors. Therapeutic ultrasound at 1 MHz frequency is optimal for structures at knee depth (3-5cm), delivering both thermal and non-thermal effects that improve capsular extensibility before stretching and range of motion exercises. This enhances the effectiveness of subsequent manual therapy and exercise.
Range of Motion Target: By Week 8, flexion should reach 0-110 degrees. This range permits normal gait and most daily activities. Patients who remain below 105 degrees at this point require more intensive intervention to prevent functional limitation.
Progressive Resistance Training: Structured strengthening exercises progress beyond bodyweight to include resistance. Key exercises include:
- Leg press (starting with light resistance, progressing to bodyweight equivalent)
- Step-ups (begin with low step, progress height)
- Mini-squats to 45 degrees (progressing depth as control improves)
- Terminal knee extension with resistance band
- Straight leg raises in all planes
Proprioception Training: Balance and joint position sense are impaired following surgery. Weight-shifting exercises, single-leg stance (initially with support), and unstable surface training begin in this phase.
Transition to Independent Walking: Most patients wean from crutches to a single stick, and many achieve independent walking during this phase. However, the criterion should be quality of gait, not speed of aid abandonment. Walking aids should be continued until normal gait pattern is restored.
Phase 4: Functional Rehabilitation Phase (Weeks 8-12)
The functional rehabilitation phase marks the transition from clinical rehabilitation to real-world activity. Patients begin applying their recovered strength and mobility to meaningful daily tasks.
MLS Laser Therapy for Residual Inflammation: A phenomenon that surprises many patients is the emergence or persistence of inflammation at 8-12 weeks post-operatively. This is normal—the healing implant-tissue interface remains biologically active. MLS (Multiwave Locked System) Laser Therapy using dual wavelengths (808nm continuous and 905nm pulsed) delivers targeted anti-inflammatory and analgesic effects to periimplant tissue. The meta-analysis by Stausholm and colleagues (2019) demonstrated significant benefits for knee osteoarthritis, and these mechanisms apply equally to post-surgical inflammation.
Range of Motion Target: The goal by Week 12 is 0-120 degrees flexion. This range allows kneeling (with cushioning), deep squatting for toileting, and most sporting activities. Some patients achieve greater range, but 120 degrees represents functional success.
Community Ambulation: Walking progresses from home and clinic environments to varied terrain: slopes, uneven surfaces, longer distances, and crowded environments requiring quick directional changes. Walking without aids in community settings is typically achieved by Week 10-12.
Return to Driving: For right knee replacement, return to driving typically occurs around Week 8, contingent on achieving adequate strength for emergency braking and sufficient range for comfortable pedal operation. Research suggests brake reaction time returns to pre-operative levels by 6-8 weeks in most patients. Left knee replacement patients (driving automatic vehicles) may resume earlier. Always confirm with your surgeon and insurance provider.
Biomechanical Gait Normalisation: Force platform analysis and 3D gait assessment objectively quantify any residual gait deviations. Common persistent abnormalities at this stage include reduced single-leg stance time, inadequate ankle push-off, and compensatory hip strategies. Targeted interventions address these specific deficits.
Phase 5: Advanced Strengthening Phase (Months 3-6)
The advanced strengthening phase transitions rehabilitation from supervised clinical sessions toward independent gym-based training, whilst continuing technological interventions to optimise muscle recovery and symmetry.
Gym-Based Programme Introduction: A structured gymnasium programme complements ongoing physiotherapy. This includes:
- Full-range leg press progressing toward 1.5x bodyweight
- Romanian deadlifts for posterior chain development
- Single-leg variations of all exercises to address any asymmetry
- Cycling for cardiovascular fitness and active range of motion
- Swimming and aquatic exercises (once incision fully healed)
Symmetry Testing: Quadriceps strength symmetry is objectively measured using isokinetic dynamometry or force platform analysis. The target is less than 20% deficit compared to the non-operated limb—a threshold associated with normal gait patterns and reduced fall risk. For patients whose contralateral knee is also affected by arthritis, age-matched normative values provide an alternative benchmark.
Sport-Specific Preparation: For patients aiming to return to recreational sport, this phase introduces activity-specific training: golf swing mechanics, tennis footwork patterns, or cycling position optimisation, depending on individual goals.
ALCE Programme Completion: The full ALCE protocol typically completes by Month 4-5, having progressed through all fibre type recruitment stages. Objective improvements in torque output and symmetry ratios document the effectiveness of this intervention.
Thermographic Monitoring: Infrared thermography provides objective monitoring of the implant-tissue interface. Elevated thermal signatures indicate ongoing inflammation requiring attention, whilst normalising thermal patterns confirm successful healing progression. This objective data guides clinical decision-making beyond subjective symptom reporting.
Phase 6: Return to Full Activity (Months 6-12)
The final phase focuses on consolidating gains, returning to meaningful activities, and establishing long-term joint health practices.
Return to Recreational Sport: Low-impact sporting activities may resume from approximately Month 6, depending on individual progress. Suitable activities include:
- Cycling (road or stationary)
- Swimming and aqua aerobics
- Golf (increasingly common post-TKR)
- Doubles tennis (with appropriate footwork modification)
- Walking and hiking
- Cross-country skiing
High-impact activities (running, singles tennis, contact sports) are generally discouraged due to accelerated polyethylene wear and increased revision risk, though individual risk-benefit discussions with your surgeon are appropriate.
HRV-Guided Intensity Progression: Heart Rate Variability (HRV) monitoring provides objective guidance for training intensity progression. HRV reflects autonomic nervous system balance and serves as an indicator of systemic inflammation and recovery status. Training intensity is modulated based on HRV trends—progressing when recovery markers are favourable, moderating when they indicate incomplete recovery.
Long-Term Maintenance Programme: Ongoing strength and flexibility maintenance is essential for implant longevity and continued function. A home exercise programme combining resistance training, flexibility work, and cardiovascular activity should become a permanent lifestyle habit.
Annual Review: Regular orthopaedic and physiotherapy review ensures any deterioration in function or emerging concerns are identified early. Radiographic assessment at intervals confirms implant positioning remains satisfactory.
Red Flags and Complications: When to Seek Urgent Review
Whilst most knee replacements proceed uneventfully, certain complications require prompt recognition and management.
Infection Signs: Prosthetic joint infection is the most serious complication, occurring in 1-2% of primary TKRs. Warning signs include:
- Fever greater than 38°C
- Increasing redness, warmth, or swelling around the wound
- Wound drainage (particularly if cloudy, discoloured, or malodorous)
- Sudden increased pain after initial improvement
- Night sweats or general malaise
Any of these findings warrant same-day medical review. Early infection treatment dramatically improves outcomes compared to delayed presentation.
DVT and Pulmonary Embolism: Despite prophylactic anticoagulation, deep vein thrombosis remains possible. Signs include calf swelling, warmth, redness, or tenderness—particularly if asymmetric (worse in operated leg). Pulmonary embolism presents with sudden breathlessness, chest pain (particularly on breathing), or coughing blood. This is a medical emergency requiring immediate attention.
Implant Malpositioning Indicators: Persistent instability (knee giving way), recurrent swelling despite adequate rehabilitation, or pain located at the implant margins may indicate malpositioning requiring orthopaedic review and further imaging.
Arthrofibrosis Prevention: Stiff knee (arthrofibrosis) occurs when excessive scar tissue restricts movement. It is largely prevented by achieving range of motion milestones in the early weeks. If flexion remains below 90 degrees at Week 6 or extension deficit exceeds 10 degrees, intensive intervention is required. In severe cases, manipulation under anaesthesia may be necessary—outcomes are best when performed before Week 12.
Pain Management Timeline: Normal vs Concerning
Understanding the expected pain trajectory helps patients distinguish normal recovery discomfort from symptoms requiring attention.
Weeks 1-2: Pain is typically most severe in the first few days, reducing significantly by Week 2. Pain requiring regular strong analgesics is expected.
Weeks 3-6: Pain continues to diminish but remains present, particularly after activity. Most patients transition from strong analgesics to paracetamol or NSAIDs.
Weeks 6-12: Baseline pain should be minimal by this stage. Activity-related pain (aching after exercise) remains common and is not concerning provided it settles within 24-48 hours.
Months 3-6: Most patients report being largely pain-free for daily activities. Exercise may still provoke temporary discomfort.
Months 6-12: Occasional aching, particularly with weather changes or after unusually demanding activities, is normal and may persist indefinitely.
Anterior Knee Pain and Patellar Clunk Syndrome: Pain localised behind or around the kneecap is common following TKR and may relate to patellofemoral tracking, scar tissue formation, or patellar clunk syndrome (a catching sensation as the patella moves over scar tissue). This typically improves over 12-18 months but warrants assessment if persistent or worsening.
Scar Hypersensitivity: The surgical scar may remain tender or hypersensitive for 6-12 months. Desensitisation techniques (textured massage, graduated pressure) accelerate normalisation.
Night Pain Resolution: Night pain and sleep disturbance are extremely common in the first 6 weeks. Sleeping with a pillow under the knee is inadvisable (promotes flexion contracture). Night pain should largely resolve by Month 3; persistent night pain beyond this warrants investigation.
The ALCE Protocol in Post-TKR Rehabilitation
Arthrogenic muscle inhibition (AMI) represents one of the most significant yet under-recognised barriers to knee replacement recovery. This neurological phenomenon—whereby joint pathology reflexively inhibits the surrounding musculature—is most severe immediately post-operatively. Quadriceps inhibition of 60-80% is documented in the first weeks following TKR (Yoshida et al., 2008), meaning patients cannot voluntarily activate their thigh muscles regardless of motivation or effort.
Traditional rehabilitation relying purely on volitional exercise faces an inherent limitation: you cannot strengthen a muscle you cannot activate. This explains the persistently high rates of quadriceps weakness reported even years after TKR in patients receiving standard rehabilitation.
The ALCE neuromuscular electrostimulation system circumvents this problem by directly stimulating motor neurons, bypassing the inhibited voluntary pathways. The electrical current activates muscle fibres regardless of arthrogenic inhibition, maintaining muscle mass during the period when voluntary activation is impossible and subsequently rebuilding strength as voluntary control returns.
Critically, the ALCE system is capable of targeting Type 2B fast-twitch muscle fibres—something standard electrical muscle stimulation cannot achieve and voluntary exercise during AMI certainly cannot accomplish. Type 2B fibres are responsible for explosive power, rapid force generation, and reflexive joint protection during unexpected perturbations (stumbles, slips, or sudden direction changes). These fibres atrophy rapidly with disuse and are the last to recover with conventional training.
The ALCE protocol is progressively structured across rehabilitation phases:
- Phase 2 (Weeks 1-4): Low-intensity protocols establishing neuromuscular activation pathways, targeting Type 1 (slow-twitch) fibres for endurance and basic activation.
- Phase 3 (Weeks 4-8): Increasing intensity targeting Type 2A fibres for moderate power and fatigue resistance.
- Phases 4-5 (Weeks 8-20): Maximum intensity protocols targeting Type 2B fibres for explosive power and rapid joint protection. Burst frequencies of 75-100 Hz specifically recruit these fast-twitch fibres.
Progress is objectively monitored through torque output measurements and symmetry ratios comparing operated to non-operated limbs. The goal is achieving less than 20% deficit—a threshold associated with normal functional capacity and reduced fall risk.
Research by Kwok and colleagues (2021) demonstrated that neuromuscular electrical stimulation following TKR significantly improved quadriceps strength and functional outcomes compared to standard rehabilitation alone. The ALCE protocol represents the most advanced application of this evidence.
MLS Laser Therapy in Post-TKR Recovery
MLS (Multiwave Locked System) Laser Therapy delivers photobiomodulation through dual synchronised wavelengths: 808nm continuous emission and 905nm pulsed emission. This combination achieves deeper tissue penetration and more effective therapeutic outcomes than single-wavelength devices.
Following knee replacement, MLS Laser provides three primary benefits:
Anti-inflammatory Effects: The surgical procedure triggers a substantial inflammatory cascade. Whilst initial inflammation is necessary for healing, excessive or prolonged inflammation impairs tissue repair, increases pain, and restricts movement. MLS Laser modulates inflammatory mediator release, reducing oedema and creating an optimal healing environment. This is particularly valuable at the 8-12 week point when many patients experience a resurgence of inflammation.
Analgesic Effects: Pain relief occurs through multiple mechanisms: reduced inflammation (removing a pain source), modulation of nerve conduction velocity, and increased endorphin release. Improved pain control enables more effective participation in active rehabilitation.
Biostimulatory Effects: At the cellular level, MLS Laser enhances mitochondrial ATP production, accelerates fibroblast activity, and promotes angiogenesis. These effects accelerate incision healing and resolution of tissue trauma.
The systematic review and meta-analysis by Stausholm and colleagues (2019), published in BMJ Open, demonstrated significant benefits of photobiomodulation for knee osteoarthritis pain and function. These mechanisms are directly applicable to post-surgical rehabilitation, where periimplant soft tissue inflammation and healing are primary concerns.
We utilise MLS Laser throughout the rehabilitation phases, with particular emphasis during Phase 4 (weeks 8-12) when residual inflammation commonly limits progress, and as needed during Phases 5-6 when intensive strengthening may provoke inflammatory responses.
Psychological Aspects of Knee Replacement Recovery
The psychological dimensions of knee replacement recovery are frequently underestimated yet profoundly influence outcomes. Fransen and colleagues (2015) demonstrated that psychological factors including fear of movement, pain catastrophising, and depression significantly impact post-TKR functional outcomes.
Realistic Expectation Setting: One of the most important psychological interventions is appropriate expectation setting before surgery. Patients expecting complete pain relief and full function within weeks are destined for disappointment. The reality—12 months to optimal recovery, possible residual minor limitations, and lifelong activity modifications—must be clearly communicated and accepted.
Kinesiophobia (Fear of Movement): Many patients develop fear of movement following surgery, concerned that activity will damage the implant or cause pain. Woby and colleagues (2007) demonstrated that fear-avoidance beliefs are significant predictors of disability in chronic pain conditions. This applies equally to post-surgical recovery. Patients must understand that appropriate movement is essential for healing and that the implant is designed to withstand normal loading.
Pain Catastrophising: Catastrophic thinking about pain—anticipating the worst, ruminating on discomfort, feeling helpless—amplifies pain perception and reduces functional outcomes. Cognitive behavioural approaches help patients develop more adaptive responses to post-operative discomfort.
Patience with the Timeline: The 12-month recovery timeline tests patience. Progress is rapid initially but plateaus and occasional setbacks are normal. Patients who accept this trajectory cope better than those fighting against it.
Meaningful Activity Milestones: Psychological recovery is often tied to returning to valued activities: gardening, golf, playing with grandchildren, or travelling. Identifying these individual goals and working systematically toward them provides motivation and psychological benefit beyond generic functional measures.
