Suggestions regarding musculoskeletal and biomechanical issues for the Nail-Patella Syndrome individual

(Revised June 2003)

 

 

 

I.                     Introduction

 

 

A.      Disclaimer-the information presented in this handout are suggestions only.  Each participant must first seek the advice of their physician before starting any kind of exercise regime where a thorough evaluation can be performed to determine what is appropriate for them.  Attendance of the presentation does not qualify the participant in any way to perform any of the suggested information without physician approval and proper supervision.

B.      Purpose-To provide individuals with a comprehensive fitness program.  The individual, along with supervision of their health care provider, can select what is most appropriate for them.  Some activities may not be appropriate and therefore should not be done. 

C.      Intent-To provide the individual with the basic knowledge and components that make up a fitness program.

D.      Recommendation-Due to the extreme variability in NPS characteristics, it is highly recommended that individuals have a MRI or scan done to determine the configuration of their joints before engaging in any exercise program.  It has been found that muscles/tendons, ligaments and even bony parts are often missing or misplaced.  Because of this, exercises would need to be modified to accommodate this.  The exercises presented in this document can be further modified for this purpose and some may not be appropriate at all.  This reinforces the importance of first consulting with your physician before engaging in any exercise program.

 

 

II.                   Handout

 

**STABILIZATION-this must be discussed before we begin discussion of flexibility and strengthening.  The shoulder blades are the stabilizers for the upper extremities and the pelvis is the stabilizer for the lower extremities. You must position the shoulder blades in place before starting the exercise for the upper extremities and also position the pelvis before starting the exercise for the lower extremities. By doing this, this allows one end of the muscles about to be exercised to be fixed in place so that you can either stretch or strengthen from there.  You will get maximum benefit if one end is anchored, so to speak, as compared to allowing both ends to move around freely.  This will make sense when you get to each exercise below. When you see the words “pull your shoulder blades down and in” and “pull up and in with your abdominal muscles”, this is the STABILIZATION needed to perform the exercises correctly.


 

A.     Flexibility

 

Stretching is a very important part of a well rounded fitness program.  It should not be overlooked.

 

When to stretch:

Stretching should be done before and after any physical activity to help prevent injury.  It is highly recommended for everyone to stretch DAILY.

 

How to stretch:

The correct way to stretch is to hold the stretch position of the muscle or muscles for a relaxed, sustained duration of time, at least 30 seconds.  STABILIZATION is important here.  Each stretch requires certain areas to be stabilized in order to fully stretch the desired muscles.  Do not stretch to the point of pain, it should feel tight, not painful. Bouncing is not appropriate, a sustained stretch is more beneficial.  Do not hold your breath while stretching, it may raise your blood pressure.  It’s a good idea to first walk around to warm up the muscles before stretching.  Since duration of the stretch is the important factor, 30 seconds, it is not necessary to do more than 3 to 5 repetitions.  Therefore, stretching does not take very long to complete.  It is the duration of the stretch, not how many, that is important.

 

Benefits of stretching:

Increases range of motion of joints

Decreases muscle tension

Prevents injuries such as strains

Prepares the body for more physical activity

Helps circulation

 

1.       Supine overhead upper extremity with simultaneous single hip flexor stretch-                                        

Lay on back, straighten one leg and pull up and in with your stomach muscles then squeeze the buttock tight on that extended leg.  Raise your arms overhead also and stretch.  After several repetitions, switch and do the opposite leg.

    

    

  

 

2.       Prone press-up

Lay on stomach and slowly raise up to prop on elbows.  Do this several times.

    

 

 

 

3.       Hamstring stretch

Lay on back next to an open door.  Place one foot on the frame of door and slowly straighten the leg.  Keep other knee bent then switch legs and repeat.

     

 

 

 

4.       Double knee to chest

Lay on back and slowly bring both knees toward chest and hold there.  Can place your hands under the calf instead of what is pictured if pushing down on knees is painful.

     

 

 

 

5.       Standing wall heel cord stretch

Face a wall and place one foot back with heel down and knee straight.  Bend front knee and slowly lean into wall.  Keep stomach pulled up and in.

    

 

 


 

6.       Prone quad stretch

Place a rope around your ankle and hold onto it with hands.  Lay on your stomach and slowly bend your knee then gently pull further with rope for further stretch.

     

 

 

 

B.     Strengthening

 

Adequate strength is necessary for people to carryout daily activities without difficulty. Strengthening specific muscles helps to strengthen, shape and tone the body.

 

When to strengthen

Strengthening should be carried out when a weakness has been determined in specific muscles and muscle groups.  Weak muscles contribute to difficulties in completing daily, recreational and athletic activities.  Weak musculature also contributes to an increase risk of injury to the body.

 

How to strengthen

Always warm up, stretch before beginning your strengthening exercises.  Proper technique while strengthening is very important.  Proper positioning on Cybex/Nautilus/Universal gym equipment etc. is necessary to avoid injury.  Where applicable, be sure to always have the axis of motion on the equipment in line with the axis of the body part being exercised.  When lifting from a standing position, be sure to: 1)  feet hip width apart.  2) equal balance forward and behind. 3)  keep knees in line with the feet.  4)  keep knees slightly bent, not locked.  There should be no pain while performing strengthening exercises.

If using free weights, proper body positioning is very important to strengthen the intended musculature and to avoid injury.  Again, as previously mentioned  STABILIZATION is vitally important to strengthen correctly.

An important comment to note here is that strengthening via the use of free weights is more beneficial when beginning a strengthening program.  Free weights strengthen individual muscles when isolated and if there is any imbalances, free weights do a better job.  Larger strengthening equipment such as cybex/nautilus/universal gym, all tend to work groups of muscles and are usually completed bilaterally. This bilateral workout tends to allow the stronger muscle groups to dominate thereby not helping to strengthen the weaker group.  Larger strengthening apparatus serve a better purpose later in the strengthening regime.

 

How often

Three times per week with at least a days rest between workouts.  If you choose to workout daily with strengthening exercises, then complete upper body strengthening one day followed by the lower body on the next day.  This method would allow a days rest for each part of the body.


 

Sets and repetitions

A set is a fixed number of repetitions.  Best strength gains are achieved when 1 to 5 sets per exercise are completed.  3 sets of 10 repetitions are considered beneficial for the average person.  If more endurance is desired then increase the repetitions to 15, 20, 25 and even higher per set while keeping the resistance lower.  Both strengthening and endurance are achieved by doing this.

For NPS, it is RECOMMENDED that higher repetitions(for endurance) with lower resistance be carried out particularly for the knee joints.  This MINIMIZES the compressive forces on the joint thereby reducing irritation and still allowing strengthening and endurance to occur. SPEED is also a very important issue, the faster the repetitions the better for minimizing the time that compressive forces are acting on the joint.  This same approach can be used for any other joint where there may be abnormal joint mechanics taking place.

 

How much weight

Use as much weight as you can tolerate for 10 repetitions.  The last repetition should be fairly difficult to perform but done so correctly.  Once you are able to do more then 10 repetitions comfortably, then increase the resistance by the smallest increment available.  You may need to drop down in your repetitions to 6 or 8 reps and progress back up to 10 repetitions.  You can progress to 2 sets of 10, then onto 2 sets of 15 or 20 reps and even higher reps to get the endurance component while still strengthening.

 

CAUTION

Do not hold your breath while working with weights.  Always exhale while performing the exertion portion of the exercise.  Always relax other muscles not involved in the exercise. Therefore, you will not substitute other muscles for help and take energy away from the muscles you are trying to strengthen.  It is best to work the larger muscle groups first and progress downward to the smaller muscles.  This is because the smaller muscles fatigue sooner than the larger ones and you could tire out before finishing your program.

 

1.      Upper Extremity

 

a.       Supine triceps

Lay on back with knees bent.  Hold weights in your hands and point your elbows toward the ceiling and keep them there.  Fully extend the elbows and repeat.  Keep shoulder blades placed down and in.

     

 


 

 

b.       Supine chest press

Lay on back with knees bent.  Hold weight in both hands at chest level and extend your arms up and down toward the ceiling.  Keep your shoulder blades down and in.  This exercise can be performed on a bench where you can drop your elbows lower to get more stretch across the chest before lifting upward.

      

 

 

c.       Prone scapular retractions

Lay on stomach with a towel roll under forehead.  First squeeze down and inward with your shoulder blades then lift hands off surface a few inches and hold. Relax then repeat.  You can progress to holding a weight in your hands.

   

 

 

d.       Sitting abduction raises with elbows bent

Sit up tall in chair with good posture and with weights in hands.  Starting with weights at shoulder height, raise upward then downward to starting position and repeat.  Keep your shoulder blades down and in and keep your stomach pulled up and in.

 


 

e.       Arm chair push-ups

Sit up tall on the front edge of a chair using good posture.  Place your hands on the arm rests.  Place your feet on floor behind the knees and lean forward and push down with your hands into arm rests and attempt to stand.  Do not need to stand up, this is just to work out the tricep muscle in the back of the upper arm.  This maneuver is also good for WHEELCHAIR BOUND people as it teaches them the proper body positioning, for transferring from the chair to another location.

 

f.         Standing bicep curls

Stand with weights in both hands held at your sides.  Bend one elbow with palm up and then turn the palm down and straighten the elbow. Keep thinking “palm up and palm down” as you work the biceps.  You can do one arm at a time or do both at same time or alternate one up while the other down as pictured.

 

 


 

2.       Trunk and pelvis

 

a.       Posterior pelvic tilts

Lay on back with knees bent.  Pull up and in with abdominals to posteriorly tilt the pelvis.  Two pictures are shown here only to visually demonstrate the posterior tilt.  The second picture is the pelvis posteriorly tilted causing a flattened back.

                          

                         

 

 

b.       Posterior pelvic tilt for upper abdominals

Lay on back with knees bent.  Pull up and in with your abdominals which flattens the back, tilting the pelvis posteriorly and perform a small curl up and repeat.

 

 

 

c.       Posterior pelvic tilt for lower abdominals

Lay on back with knees bent.  Pull up and in with abdominals as above, then while maintaining this, lift one leg up slightly then place it back down.  Repeat with the same leg and complete before moving onto the other leg.

    

 

 


 

d.       Sidelying hip abduction with knees bent and over pillow

Lay on your side with a pillow between your thighs.  First pull up and in with your abdominals then raise your upper thigh up and outward from the pillow and return.  Do same for other leg.

    

 

 

 

e.       Sidelying hip adduction

Lay on your side and bend your top leg and place the foot in front of bottom leg.  Keep the bottom leg straight.  First pull up and in with abdominals then lift bottom leg up a few inches then return.  Do same for other leg.

 

 

f.         Prone gluteus lift with knee bent and over a pillow

Lay on stomach with a firm pillow under your pelvis and forehead resting on a towel roll.  Bend one knee then squeeze that buttock tight then lift that leg upward a few inches and hold for 3 seconds and relax. Repeat and do same for other leg.

 

 

 

g.       Prone gluteus lift with leg straight

Lay on stomach with forehead resting on a towel roll.  Squeeze one buttock tight then lift that leg upward a few inches and return and repeat. Do same for other leg.

 


 

h.       Prone opposite arm and leg lifts

Lay on stomach with forehead resting on a towel roll.  Squeeze buttock tight on one side and lift leg upward at the same time you pull your shoulder blade down and in on opposite arm and lift arm upward as pictured. Arm and leg should be lifted upward at the same time.  When done, then do same for other leg and arm.

 

 

 

 

3.      Lower Extremity

 

a.       Quad sets

Sit up tall with both legs straight.  Pull up and in with your stomach muscles then tighten both your thigh muscles as if you are trying to push the back of your knees downward.  You can place your hand there to feel the back of knee push downward.  Hold the contraction for up to 5 to 10 seconds.

 

 

b.       Short arc quads

Sit up tall with a firm roll under one knee.  Turn that foot slightly outward.  Beginning with the knee bent over the roll, fully straighten the knee then relax and repeat.  Do same for other leg. Make sure to hold your stomach up and in.

     

 


 

c.       Straight leg raises

Lay on your back with one knee bent and other one straight.  Pull up and in with the abdominals then lift the straight leg up parallel with the other thigh then lower and repeat.  To facilitate more of the inside(medial) muscles, turn the foot outward on the straight leg before you lift.  Do same for other leg.

      

 

 

d.       Standing double leg mini squats

Stand with your back to a wall and your feet approximately 6 inches from the wall.  Feet are shoulders width apart and perform a slight squat.  Hold this position until you feel fatigue in the quad muscles just above the knee.  Repeat.  Keep stomach tucked in and shoulder blades down and in.

 


    

e.       Mini step-ups, forward,  sideways and backwards

Place a phone book on floor and stand facing it.  Shift your weight to one heel and step up onto the phonebook with the other foot using good posture form and holding your stomach muscles up and in.  By being on your heel this prevents you from “pushing off” and making the exercise easier.  Step up and then down repeatedly until you feel fatigue in the front thigh muscles then do same for other leg.  As pictured below, you can do this by stepping sideways and also backwards.  The backward one is the most challenging.

 

                                           

 

 

C.    Cardiovascular Endurance

 

Cardiovascular exercise, also known as “aerobic” exercise, is probably the most important aspect of a total fitness program.  Strength and flexibility are also important but it is aerobic exercise that keeps the heart and lungs strong and more efficient.  Aerobic training also keeps body fat levels down.  Aerobic activities are those activities that demand oxygen and that utilize large muscle groups in a continuous, rhythmic fashion.  Aerobic exercise causes the body to burn fat for its fuel during the activity.  Examples of aerobic exercise are walking, swimming, indoor and outdoor bicycling, treadmill, stairstepping machine etc.  Of course, jogging and running are also aerobic but are much harder on the joints.  Before engaging in any aerobic activity, it is important to first warm up by completing general stretching or flexibility exercises and brief walking to prepare the body.  Before starting any aerobic training, it is best to first check with your doctor.  This is particularly true if you have a history of heart disease or are over the age of 35 and/or have not engaged in any regular exercise. If you have any other concerns regarding your present health status, it is best to check with your doctor.

 

Key components of an aerobic workout are:

1.       Know your target heart range.

2.       Type of activity-choose an activity which is BEST SUITED for you based on your medical history and your interests.

3.       Duration-it is best to carryout your aerobic activity for at least 20 minutes or longer to achieve aerobic benefits.

4.       Frequency-it is best to complete your aerobic activity 3 times per week or more in order to gain any benefit.

5.       Progression-aerobic exercise should be progressed by either increasing the intensity or the duration or a combination of the two in order to further your progress and condition your cardiovascular system.

 

Determining your target heart range:

               220 – age = MHR (Maximal heart rate)

               MHR x .5 = 50% of maximal heart rate (for beginners)

               MHR x .8 = 80% of maximal heart rate

50 to 80% of your maximal heart rate is considered a safe target heart range to exercise aerobically in, unless otherwise indicated.

 

Monitoring your heart rate:

Your pulse should be monitored regularly to ensure that you are exercising properly in your target heart range and progressing as you should.

 

Counting your pulse:

Place your first 2 fingers on your opposite wrist just below the thumb.  You should feel a pulsating sensation, this is your pulse. Count the beats for 6 seconds and multiply that number by 10, this is your heart rate per minute and this rate should fall in your target heart range. 

As you become more fit, your heart rate will drop at the same workloads.  You will need to either increase the duration as long as your heart rate is still in your target heart range or increase the intensity of the activity to keep your pulse in your target heart range.

 

How to choose the right aerobic activity:

You must consider your interests and also your present health status.  Some activities are not appropriate for certain health conditions, for example, jogging or running on arthritic knees.  It is also equally important that you choose an activity that you like, therefore, you will be more likely to continue the activity indefinitely. 

 

Benefits of aerobic exercise:

1.       Helps to decrease body fat

2.       Helps to reduce cholesterol levels

3.       Builds endurance

4.       Lowers the resting heart rate

5.       Increases the ability of the heart to supply oxygen to the body

6.       Increases lung capacity

7.       Helps with blood pressure control

8.       Reduces stress and tension

 

Do not be afraid to choose several different activities for your aerobic conditioning.  This will allow you to use different muscles and offer variety to your program.

 

Remember that you do not have to complete your whole program at one time.  You can choose to do your aerobic workout on certain days and do your strengthening exercises on other days.  Stretching is best to be completed daily and you should always warm up before and after your aerobic activity and strengthening exercises. 

Just before meal time is a good time to complete an aerobic workout since it helps to curb your appetite.

   


               

 Examples of aerobic exercise are:

1.       Ergometer-also known as indoor bicycle.  For NPS knees, it is best to place the seat high enough so that there is little bend in the knee when the pedal is up but still keeping the foot on the pedal when the pedal is down.  This position will minimize compressive forces on the knee joint and emphasize use of the vastus medialis muscle which helps to pull the patella away from the outside of the knee where it can cause pain.  The same principle can be applied for outdoor biking.

 

2.       Walking-While walking, this is an opportunity to practice good posture technique.  Also, good walking shoes with good arch support and cushioning.

 

3.       Swimming-This activity offers the least weight bearing through the joints because of the buoyancy of the water.  Arthritis sufferers benefit from this activity. Stretching, strengthening and aerobic conditioning can be completed in the water.  POOL TEMPERATURE is very important.  If swimming laps and you can tolerate being in cooler water, pool temperature from 82 to 86 degrees is okay for swimming laps.  If performing strengthening exercises such as arthritis classes, therapeutic pools etc., then pool temperature around 90 to 92 degrees is more beneficial. If have a heart condition, check with your doctor first to see if 92 degree water temperature is a contraindication for you.

 

 

D.    Posture

 

Exhibiting proper posture for sitting, standing and while doing your everyday activities is very important.  It helps to maintain an equal balance of the muscles on the skeleton.  As we age, gravity takes it toll on our bodies and if we do not use proper posture practices, muscles imbalances begin to occur throughout the body and can be one of many reasons for pain and can contribute to injuries. Poor posture produces a forward head, forward or rounded shoulders, very little curvature in the low back or just the opposite with extreme swayback, locked in knees for standing and flat feet. These are just a few of the more common observations.

Indicated below are examples of poor posture and good posture.  Awareness and simple cues can begin to correct poor posture along with corrective exercises.  NPS people can benefit tremendously from this knowledge as it is known that there are bone and muscle structure differences in the body.
