Chapter 21b Clients with Orthopedic, Injury and Rehabilitation Concerns NSCA’s Essentials Shoulder Because of the type of joint and area of the shoulder, it is a structure that can be susceptible to injury The following sections discuss indicated and contraindicated exercises, strategies, etc. for clients with shoulder issues The trunk and hips are vital to shoulder function, the legs provide 51-55% of the total kinetic energy and total force for overhead activities. A program for shoulder health should include strengthening exercises for the hip rotators, hip abductors, and hip extensors, as well as the abdominal and low back stabilizing muscles Shoulder Shoulder Impingement Syndrome Essentially is pinching of the supraspinatus (part of the rotator cuff…remember SITS), the long head of the biceps or the bursa underneath the acromial arch (subacromial bursa) Can be treated conservatively or with surgical procedures Causes for surgical procedures include: Abnormalities of bone (example…a hook acromion process that compresses structures) Shoulder Factors that may be altered Muscular imbalances ROM (if limited) Poor posture Poor scapula control Poor and improper exercise technique Overuse issues of the shoulder (overhead activities…what are some examples of overhead activities that could contribute to this problem?) Shoulder Movement and Exercise Guidelines See Figures 21.5 to 21.9 (pg. 545-546) (series of exercises recommended for rotator cuff activation with minimal use of other muscle groups) These are very common exercises use in nonsurgical and surgical rehab programs The rotator cuff muscles have a primary function in endurance so these exercises are performed typically in this manner: Light weights (really no more than 4 or so pounds) High reps (15-20) Shoulder The other great thing about these exercises is that they put the shoulder in a safe position This position is neutral environments below 90 degrees of elevation with the arm in a forward position relative to the body (think anterior to frontal plane…remember frontal plane…abduction/adduction) These exercises are great for pain free exercises and decreasing chances of shoulder impingement Shoulder Clients need to concentrate on strengthening rotator cuff and scapula muscles For example…rowing exercising (seat row, etc.) are great for increasing rhomboid and trapezius strength Overhead pressing activities and bench press should be used cautiously (decline bench may be better = inside safe zone) Upright row should be used cautiously as well (rowing elbows too high can aggravate the impingement type pain) Some cardio equipment may be a problem as well (versaclimbers place the arm above the head and could cause impingement aggravation) Racket sports should be used with caution as serving overhead or smashing a shot from high above and down could cause aggravation Shoulder Anterior Instability This is when the glenohumeral joint moves too far forward, which then can cause injury such dislocation Following dislocation, re-dislocation is a high possibility (90% in young active individuals, 3050% in middle aged individuals…why the difference?) This is a difficult rehabilitation areas due to the laxity and instability of this area structurally Shoulder Movement and Exercise Guidelines Indications for strengthening instability are similar to impingement (strengthen rotator cuff and scapula muscles) Use similar exercises like in 21.5-9 (pg. 545-546) Movements that are contraindicated and could lead to dislocation: Greater than 90 degrees of elevation Hands and arms behind plane of shoulder Follow safe zone guidelines: Activities below 90 degrees of elevation of the shoulder (see figure 21.10 pg. 548) Arms anterior to frontal plane of the body (see figure. 21.10 pg. 548) Shoulder Rotator Cuff Repair Carried out when damage to the rotator cuff tendons-most often the tendon of the supraspinatus muscle-occurs These tears cause altered joint mechanics and usually require arthroscopic surgery. Two days to six weeks in a sling, but surgeon decides on recovery time Shoulder Ultimately clients may choose a conservative approach based on exercise or choose surgery Allow for exercise modifications regardless of choice to protect structures Even with treatment completed clients should try to remain in safe zone in activities Exercises outside of the safe zone are contraindicated Shoulder Movement and Exercise Guidelines Often discharged from formal rehabilitation three to four months following the surgery Contraindicated exercises listed in table 21.4, pg. 547 Contraindicated exercises High resistance training and low-repetition upper extremity strengthening Exercises outside of the safe zone Examples of exercises: Shoulder press Bench press Behind the neck lat pulldown Racket sports swimming Shoulder Movement and Exercise Guidelines Exercises 21.5-9 are also applied for strengthening after rotator cuff repair, but usually not until four to six weeks after surgery Table 21.4 provide contraindicated activities Overhead lifting and push ups/bench press are contraindicated (can result in overload of cuff) Lower body aerobic exercises are well suited (walking, running, etc.) Shoulder Conditions Requiring Shoulder Exercise Modification Rotator Cuff Repair Rotator Cuff Tendonitis Glenohumeral joint instability (prior dislocation, etc.) Acromioclavicular joint injury (separation) Glenohumeral joint osteoarthritis) See Table 21.5 (pg. 550) for “Shoulder Exercise Modifications” Shoulder So…let’s take some time and go through the pictured exercises on pg. 545-546 of your text and Table 21.5 on pg 550 Let’s get to it! Knee Anterior Knee Pain Common knee issues include: Chondromalacia Iliotibial band friction syndrome Irritated plica Patellar tendonitis Client with these issues commonly describe pain from prolonged sitting and walking up and own stairs Lots of times diagnosis is based upon overuse, biomechanical issues, and muscular imbalances Rehabilitation focuses on reducing pain and inflammation, correcting biomechanical faults and optimizing tissue function Knee Movement Exercise Guidelines Increase quadriceps strength as it improve functional activities (walking up and down stairs) and increasing patellofemoral function and reduces knee pain Deep squats, closed kinetic chain activities or exercises requiring knee flexion more than 90 degrees should be used cautiously Aerobic activities that require deep squatting or lunging should be avoided (contraindicated) Cycling or water based activities can be used to maintain client’s aerobic base It is common for anterior knee pain clients to use some form of taping or patellar support Knee Anterior Knee Pain Movement contraindications (table 21.7, pg. 553) Exercise contraindications Closed chain knee movements with > 90 degrees of knee flexion Open chain knee movements 0 to 30 degrees of knee flexion Closed chain: full squat, full lunge Open chain: end range leg extension, stair stepper with large steps Exercise indications Closed chain: ¼ to ½ squat and leg press Open chain: partial lunge; leg curl, stair stepper with short, choppy steps Knee Anterior Cruciate Ligament Reconstruction Exercise after ACL reconstruction is vital to recovery ACL controls knee motion and proprioceptive feedback Recent reconstruction technology advances have allowed for a speedier recovery from ACL tears A graft of the central third of the patellar tendon or the hamstring is usually the graft source Emphasis on reducing inflammation Knee Movement and Exercise Guidelines Post-operative contraindications include: Immediate active or resistive knee flexion until six weeks after surgery Hamstring grafts preclude immediate post-operative active or resistive knee flexion until approximately three to four weeks following surgery For either graft discharge can be as early as four to six weeks During rehab open (straight leg raises, leg curl, extension, abduction, etc.) and closed kinetic chain (lunges, squats, leg press, etc.) activities are recommended and important Leg extension exercises should be performed with a range of motion of 90 degrees of knee flexion to 45 degrees of knee extension to decrease stress on ACL (adhere to this for a minimum of six months to a year) Knee Open chain vs. Closed chain Open chain Exercises that have the distal aspect of the extremity terminating free in space. Ex: leg curl/extension, hip flexion/extension Closed chain Exercises that occur with the distal part of the extremity fixed to an object that is either stationary or moving. Ex: leg press, squat, step-ups, barbell bench press Knee Movement and Exercise Guidelines (Table 21.7, pg. 553) Movement contraindications Exercise contraidications Open chain knee movements with <45 degrees knee flexion Active hamstring exercise (those with hamstring graft) for four to six weeks End range of leg extensions Exercise indications ¾ squat and leg press Step-up Leg curl Stiff-legged deadlift Elliptical trainer Knee Total Knee Arthoplasty Total knee replacement…generally due to year of stress and repetitive load on the knee (degeneration on the joint surfaces of the distal femur and proximal tibia) Prosthetic components are inserted to cover worn areas at the ends of both the femur and tibia Rehab is immediate with range of motion the focus Emphasis on range of motion Knee TKA Movement and Exercise Guidelines Contraindications Movements greater than 100 degrees of flexion are risky and can cause undue stress on knee Exercises requiring kneeling (bent-over dumbbell row, lunges too deeply Indications Exercises using less than 90 degrees knee flexion postures are recommended in both open and closed kinetic chain exercises Cycling Swimming Endurance-based activities that minimize joint impact loading Specific resistance exercises such as leg press, calf raise and knee flexion with low resistance and high reps Knee TKA (movement and exercise guidelines) Movement contraindications (Table 21.7, pg. 553) Exercise contraindications Closed chain knee movements wth > 100 degrees knee flexion Kneeling Full squat Full lunge Exercise indications ¼ to ½ squat and leg press Partial lunge Leg extension and leg curl Stationary bicycle Aquatics, swimming Hip Trainers will encounter very few hip injuries or procedures Hip is much more stable than shoulder or knee joint Hip Hip Arthroscopy Post-procedure Focus on restoration of ROM, strength, and gait Total time to return to activity is about 16 to 32 weeks but is determined by the extent of the surgical repair Hip Hip arthroscopy Movement and exercise guidelines (Table 21.8, pg. 557) Movement contraindications Forceful hip flexion Hip abduction and rotation (early phase of rehabilitation) Exercise contraindications Ballistic or forced stretching Exercise indications Aquatic walking Hip Total Hip Arthroplasty (Hip Replacement) Usually recommend if non-surgical procedures do not work Replacement of hip provides about 15 years of pain free movement Two types of prostheses Cemented Affixing the femoral and acetabular components with bone cement Uncemented Allow direct attachment of the prosthetic components to the bone Hip Cemented allows for immediate post-op weight bearing Uncemented need six to twelve weeks wait time before weight bearing after surgery THA restrictions No hip flexion greater than 90 degrees No hip adduction past neutral No hip internal rotation Hip Movement and Exercise Guidelines (Table 21.9, pg. 558) Trainer should first contact surgeon to see if there are any other restrictions for exercise Weight bearing status: ROM limitations Posterolateral approach: Immediate full weight bearing Anterolateral approach: Restricted weight bearing for ≥ 6 weeks Transtrochanteric approach: Restricted weight bearing for ≥ 6 weeks Posterolateral approach: Flexion > 90 degree, abduction, medial rotation Anterolateral approach: Extension, adduction, lateral rotation Transtrochanteric approach: Extension, adduction, lateral rotation Functional movement precautions Moving in and out of a chair, hip flexion (putting shoes on) Turning away from surgical hip Turning away from surgical hip Arthritis Two primary arthritis classifications Osteoarthritis Degenerative joint disease Progressive destruction of joint’s articular cartilage Rheumatoid Arthritis Systemic inflammatory disease affecting not only the joint surface, but also connective tissue (capsules and ligaments) Arthritis Osteoarthritis Movement Exercise Guidelines (Table 21.10, pg. 559) Movement contraindications High-impact activites Exercise contraindications running Snow skiing Jogging Exercise indications Bicycle Stair stepper Elliptical trainer Aquatics, swimming Arthritis Rheumatoid Arthritis Movement and Exercise Guidelines (21.11, pg. 560) Movement contraindications High-impact cardiovascular exercise Neck flexibility or strangthening in clients with history of neck

flexibility exercises Isometric exercise (for the unstable joint) Water aerobics Stationary bicycling Arthritis Common Modifications to Exercise Common affected areas are cervical spine, shoulders and wrists Cervical spine Shoulders Avoid neck stretching or manual resistance in that area Avoid impingement prone positions (upright row) Wrists Increase diameter of bar, dumbbell or handle to offset weakened grip May add a padding to a dumbbell bar
