EXERCISES ON PATELLOFEMORAL PAIN SYNDROME IN AMATEUR

SQUASH PLAYERS ”

6 Brief resume of the intended work :

6.1 INTRODUCTION

Squash is a high-intensity sport that requires high-speed movements around the court

while maintaining control over ball placement and being aware of the spatial orientation of

the opponent. In order to hit the ball, squash players need large range of joint motion and

velocity of limb action.

Injury risk factors in squash include the physical demands of the sport, the speed,

size and physical properties of the ball, court surfaces, the confined area of play and close

proximity of players while swinging a racket. The general injury prevalence among squash

players is about 45%. [1]

A critical review of squash epidemiological studies indicated that squash players most

commonly report acute soft-tissue injuries at hospital emergency departments. Lower-limb

injuries account for the majority of the injuries sustained by squash players. The knee and

ankle joint are reportedly the most commonly injured body regions in squash. Some of the

factors that may increase your risk of injury include age, poor fitness level, poor technique -

puts unnecessary strain on joints and muscles.[1]

In this sport, 58% of injuries affected the lower limb. Injuries in squash players most

frequently affected the knee, lumbar region, ankle and muscles, especially the calf . Squash

players face up more injuries (59%) in comparison with the tennis (21%) and badminton

(21%) ones. On the other hand, injuries to the lower limbs in squash are common and relate

to the acute physical stresses increase in the nature of the sport, as well as the more chronic

overuse type of injuries. Since players are active for most time of the game, they may face

more sport injuries.[2]

A study showed that knee injuries seen in squash players are collateral ligament (33%),

patello femoral (23%), patella dislocation, meniscal (19%), cruciate ligament (6.8%)

traumatic synovitis (9%) other (6.7%) [2]

Patellofemoral pain syndrome (PFPS) is described in the literature as anterior knee pain,

caused by aberrant motion of the patella in the trochlear groove, which results from

biochemical and/or physical changes within the patellofemoral joint (PFJ). PFPS exists

without gross abnormality of the articular cartilage. It is a problem of chronic overload of

the muscles of the lower extremity.[3]

Patellofemoral pain syndrome (PFPS) is a common musculoskeletal complaint

characterised by pain in front of the knee which is provoked by activities such as walking up

and down stairs, sitting with flexed knees for long periods, running, kneeling and squatting[4]

Patellofemoral pain syndrome (PFPS) is usually due to weakness of vastus medialis

obliqus (VMO) resulting in abnormal patellar tracking.[5]

Pain at the front of the knee or ''behind the knee cap'' is a common problem for many

sports people and can be very debilitating. This condition has a number of names including

''Patello-femoral Pain Syndrome'' & "Runners Knee". The problem occurs between the

patella (kneecap) and the femur (thigh bone). Under normal circumstances, the kneecap

presses against the lower portion of the thigh bone when the knee is in a bent position.[6,7]

Patellofemoral syndrome (PFPS) is one of the most common joint complaints and affects

athletes and non-athletes alike. PFPS patients report of symptoms of anterior knee pain,

aggravated by functional activities. Patellar crepitation, swelling and locking are other

symptoms.[8]

During running or any step, squat or landing & jumping activity, the kneecap moves up

and down or ''tracks'' against the thigh bone and in so doing, acts as a fulcrum, which

provides a mechanical advantage for the front thigh muscles (the quadriceps). High forces

are produced between the kneecap and thigh bone during such activities. Decreased soft-

tissue flexibility is also evident in adolescents due to the inability of soft tissues to

accommodate the rapid growth of skeletal structures such as the long bones.[9,10]

There is a commonly accepted concept that conservative rehabilitation induces symptom

relief for PFPS patients. Different treatments can be tried to reduce the pain and difficulties

experienced during daily activities, including drugs, electric modalities and massage.

Exercise regimens to strengthen the muscles surrounding and supporting the knee are other

options.[10]

Young squash players are now participating at relatively more competitive levels of

play compared with 20 years ago. This shift in focus among young people from enjoyment

of physical activity to competitiveness is placing high demands on the musculoskeletal and

physical systems. Injury risk factors in squash include the physical demands of the sport, the

speed, size and physical properties of the ball, court surfaces, the confined area of play and

close proximity of players when swinging a racket.[11]

As with many musculoskeletal conditions, multiple biophysical agents, such as

ultrasound, electrical stimulation, and ice, are also often used to treat individuals with PFPS.

Therapeutic ultrasound is one of many rehabilitation interventions available for reducing

pain and inflammation. “Ultrasound is a form of mechanical energy consisting of high

frequency vibrations”. These vibrations result in acoustic streaming and radiation forces,

both of which enhance the flow of particles from one side of a cell membrane to the other.

Thus, ultrasound increases cell permeability. As a result of stable cavitation ultrasound also

“exerts mechanical stresses on the surrounding cells or other structures. Pulsed ultrasound is

generally recommended for treatment of pain and inflammation in acute stages, while the

continuous ultrasound is recommended for treatment of restricted movement.[12,13]

Open kinetic chain (OKC) exercises are single joint movements that are performed

in non-weight bearing with a free distal extremity. In contrast closed kinetic chain (CKC)

exercises are multi-joint movements performed generally in weight bearing with a fixed

distal extremity. The treatment often includes quadriceps femoris muscle strengthening

exercises in an open kinetic chain (OKC) or closed kinetic chain (CKC).[14]

A study showed that OKC and CKC exercises promoted a reduction in the pain

intensity and improvement of the functionality in PFPS bearers. The force unbalance

between the vastus medialis oblique (VMO) and the vastus lateralis (VL) muscles, which

are the main dynamic stabilizers of the patella is considered the main factor that causes the

symptoms onset. [14]

6.2 Need for the study :- The reviews of literature on PFPS have found some evidence that exercise

therapy might help to reduce the pain of PFPS. There are many studies that talk about the

effect of OKC and CKC exercises on PFPS but there are hardly any literature available on

the combined effect of ultrasound and exercises on PFPS, So the aim of this study is to find

out whether exercise therapy along with ultrasound has any effect in the reduction of pain of

PFPS in amateur squash players.

6.3 Hypothesis :-

Null hypothesis: There will be no effect of ultrasound and open versus closed kinetic chain

exercise in patellofemoral pain syndrome in amateur squash player.

Experimental hypothesis: Ultrasound and open versus closed kinetic chain exercise will

help to reduce pain and improve muscle strength of patellofemoral pain syndrome in

amateur squash players.

6.4 Review of Literature:-

Outcome measures:-

Tugba Kuru, Elif Elçin et al(2009) :Validity of the Turkish version of the Kujala

patellofemoral scoring patellofemoral pain syndrome. There has been no functional

assessment scale validated for Turkish patients with patellofemoral pain syndrome. Internal

consistency of the Turkish version of the Kujala patellofemoral score showed good

reliability and test-retest results showed high reliability, suggesting that it is an appropriate

functional instrument for Turkish patients with patellofemoral pain syndrome. Cronbach’s

alpha calculated for internal consistency of the Kujala patellofemoral score was 0.84.

Correlation coefficients of the items to estimate test-retest reliability ranged from 0.613

(p=0.004) to 1.000 (p=0.000), with the mean correlation coefficient of 0.944 (p=0.000). [17]

Roos em, Klässbo M, Lohmander Ls.womac et al(1999): Osteoarthritis index. Reliability,

validity, and responsiveness in patients with arthroscopically assessed osteoarthritis.

Western Ontario and MacMaster Universities. Test-retest reliability, internal consistency,

validity, and responsiveness were determined in 52 patients with arthroscopically assessed

cartilage damage of the tibio-femoral knee joint. The Swedish version of WOMAC is a

reliable, valid, and responsive instrument with metric properties in agreement with the

original widely used version.[22]

Bert m. chesworth e lsie g. culham et al(1989): Validation of Outcome Measures in

Patients with Patellofemoral Syndrome. The purpose of this study was to determine the

reliability and validity of the following outcome measures in a group of 18 patients with

patellofemoral pain syndrome, the visual analog pain scale (VAS), a functional index

questionnaire (FIQ), selected temporal components of gait on level walking and ascending

stairs, knee joint angle on downhill walking, and electromyographic activity of the

quadriceps during stair climbing. Subjects were tested at initial assessment (time 0), after 24

hours (time I), and after clinically significant improvement, following a course of treatment

(time 2). Using the intra-class correlation coefficient (r,), the VAS (r, = 0.603) and FIQ (r, =

0.483) exhibited a poor day-to-day reliability (time 0 versus time 1).[20]

Squash injuries:-

L Meyer Q Louw et al(2007): Prevalence of musculoskeletal injuries among adolescent

squash players in the Western Cape. The aim of the study is to determine the prevalence of

musculoskeletal injuries among adolescent squash players in the Western Cape. Injury data

were collected for 106 players at three schools randomly selected from a list of the top 10

schools in the Western Cape high school squash league of 2005. An adapted structured self-

administered questionnaire based on a previously validated musculoskeletal injury

questionnaire was used to collect the data. The main variables investigated were prevalence,

mechanism and injury site of musculoskeletal squash injuries. Authors concluded that a

relatively high prevalence of squash injuries was found.[1]

K. Steininger, Dr. med. and R. E. Wodick, et al(1987): Sports-specific fitness testing in

squash. The field test was performed in a squash court. Six light bulbs were connected to a

programming device causing individual bulbs to light up in a given sequence. The players

were instructed to react to the flashes by running towards and striking balloons mounted in

the vicinity of the bulbs. The results show that a valid estimate of fitness can be derived

from measurements involving exercise closely resembling that which is specific for the

sports activity in question. Improved training advice and guidance may result from such

studies.[18]

M. D. Chard, and S. M. Lachmann et al(1987): Racquet sports patterns of injury

presenting to a sports injury clinic. The purpose of this study was to investigate and

compare the pattern of injuries presenting to a sports injury clinic in players of the racquet

sports squash, badminton and tennis. In an 8-year retrospective study, 631 injuries due to the

racquet sports of squash (59%), tennis (21%) and badminton (20%) were seen in a sports

injury clinic, males predominating (58 to 66%). So the study concluded from detailed

assessment of 106 cases showed many to be new, infrequent, social players. Poor warm-up

was a common factor in new and established players.[2]

Burton L. Berson et al(1981): An epidemiologic study of squash injuries. A retrospective

investigation of squash-related injuries incurred at a private and a public club in New York

was undertaken to gain insight into the incidence and nature of such injuries. Telephone

interviews were conducted with 200 randomly selected individuals to obtain their entire

injury history. Sixty-nine of the 155 squash players contacted sustained injuries during their

participation. Some had multiple injuries. This resulted in an overall injury rate of 44.5%.

Nearly one-half of the injuries involved the lower extremity, with the lower leg being

injured most often. Forty-seven percent of the injuries seen were considered disabling

because the patients were out of action for more than two weeks after injury. Only rarely

will an injured squash player become permanently impaired.[21]

PFPS and interventions:-

Heintjes EM, BergerM et al(2009): Conducted a study to find out exercise therapy for

patella femoral pain syndrome. This review aims to summarize the evidence of effectiveness

of exercise therapy in reducing anterior knee pain and improving knee function in patients

with PFPS. From 750 publications 12 trials were selected. All included trials studied

quadriceps strengthening exercises. The study concludes that exercise therapy is more

effective in treating PFPS than no exercise was limited with respect to pain reduction, and

conflicting with respect to functional improvement. There is strong evidence that open and

closed kinetic chain exercise are equally effective.[7]

Brosseau L, Casimiro L, Welch V, et al(2009): Therapeutic ultrasound for treating

patellofemoral pain syndrome. To assess the effectiveness and side effects of ultrasound

therapy for treating patellofemoral knee pain syndrome. All randomized controlled trials

(RCTs), controlled clinical trials (CCTs), case-control and cohort studies comparing

therapeutic ultrasound against placebo or another active intervention in people with

patellofemoral pain syndrome were selected according to a prior protocol, Ultrasound

therapy was not shown to have a clinically important effect on pain relief for people with

patellofemoral pain syndrome. These conclusions are limited by the poor reporting of the

therapeutic application of the ultrasound and low methodological quality of one of the trial

included. No conclusions can be drawn concerning the use, or non-use, of ultrasound for

treating patellofemoral pain syndrome. More well-designed studies are needed.[13]

Anil Bhave, Erin Baker et al(2008): Conducted a study Prescribing Quality Patellofemoral

Rehabilitation before Advocating Operative Care. The study has classified patients in three

categories of pain level: acute, sub-acute, or chronic. Authors conclude that Prescribing

Quality Patellofemoral Rehabilitation before Advocating Operative Care, in the acute phase,

the goal of therapy is to reduce inflammation, increase patellar mobility, and improve

quadriceps strength. If lateral structures are tight, then pulsed ultrasound are useful to break

up scar tissue and improve flexibility.[15]

Cristina Maria Nunes Cabral1, Angela Maria de Oliveira Melim et al(2007): Effect of a

closed kinetic chain exercise protocol on patellofemoral syndrome rehabilitation. The

purpose of this study was to verify the efficacy of quadriceps femoris muscle strengthening

exercises in a closed kinetic chain (CKC) in the treatment of patellofemoral syndrome. The

10 PFPS patients performed quadriceps femoris strengthening exercises using a leg-press

with progressive increase in resistance during eight weeks, twice a week. The results of the

present study permit the suggestion that the proposed quadriceps femoris strengthening

exercises with ROM control should be prescribed for PFPS patients since, they improve the

knee functional level. Moreover, progressive resistance increases according to the pain level

should be used in patients with muscle skeletal disorders to protect the joints.[9]

Guilherme Lotierso Fehr1, Alberto Cliquet Junior et al(2006): Effectiveness of the open

and closed kinetic chain exercises in the treatment of the patellofemoral pain syndrome. The

aim of this study was to analyze the therapeutic effects of the open kinetic chain and closed

kinetic chain exercises to treat the patellofemoral syndrome. 24 volunteers were randomly

divided in two groups: group (I) performed the OKC exercises; group (II) performed the

CKC exercises. Both groups were submitted to eight consecutive weeks of treatment

consisting of three weekly sessions performed in alternate days. The results found in this

study suggest that according to the conditions of the trial, the OKC and CKC exercises

provoke no changes in the patterns of the EMG activation in the VMO and VL muscles.[16]

Ann-katrin stensdotter, paul W. Hodges,et al(2003): Quadriceps Activation in Closed

and in Open Kinetic Chain Exercise. The aim of this study was to examine whether the

quadriceps femoris muscles are activated differently in open versus closed kinetic chain

tasks. Ten healthy men and women extended the knees isometrically in open and closed

kinetic chain tasks in a reaction time paradigm using moderate force. Surface

electromyography (EMG) recordings were made from four different parts of the quadriceps

muscle. The onset and amplitude of EMG and force data were measured. Authors concluded

that, exercise in closed kinetic chain promotes more balanced initial quadriceps activation

than does exercise in open kinetic chain. This may be of importance in designing training

programs aimed toward control of the patellofemoral joint.[14]

Danielle A.W.M. Vander Windt (1999): Ultrasound therapy for musculoskeletal disorders

a systematic review. The objective of this review was to evaluate the effectiveness of

ultrasound therapy in the treatment of musculoskeletal disorders. Data from the original

publications were used to calculate the differences between groups for success rate, pain,

disability and range of motion. Statistical pooling was performed, if studies were

homogeneous with respect to study populations, interventions, outcome measures and

timing of follow-up. Study concluded there is a little evidence to support the use of

ultrasound therapy in the treatment of musculoskeletal disorders.[23]

7.6 Methodology

Intervention to be conducted on participants:-

Subjects who fulfill the inclusion and exclusion criteria will be included in the study

and an informed consent will be taken from each of the subjects prior to participation.

Instructions are given to the subjects about techniques performed.

A total of 30 subjects will be divided equally into 2 groups by random lottery method.

Group A (n=15) Group B (n=15); Group A will receive closed kinetic exercises and

ultrasound, Group B will receive open kinetic exercises and ultrasound.

As to the dynamic CKC exercises (450 leg press) and the OKC exercises (quadriceps

table), one repetition maximum (RM) of the quadriceps for each subject is found. The

treatment protocol consists of three weekly physiotherapy sessions performed along eight

weeks in alternate days and standard progressive resisted exercise programme (PRE)

protocol is followed for strengthening quadriceps. Review to be taken after every two month

and outcome measures are taken before and after the treatment.

Testing procedure:- Group A: To the group submitted to the CKC protocol in both static and dynamic,

the subjects would perform during the semi-squatting exercise in its eccentric phase

(down) and in the concentric phase (up). From the stand up position, the volunteers

will perform five repetitions of the squatting and rising movements, and one minute

rest will be granted between each set. Exercises will be performed for five

repetitions and gradually progressed, exercises are static exercise of the quadriceps

with the knees at a 200 angle, static exercise of the quadriceps with the knees at a 400

angle, Semi squatting (00 to 500), Leg press (00 to 500). After exercise subject will

undergo ultrasound therapy with an intensity of 1W/cm2 for 8 minutes using a pulsed

mode 1: 1 ratio with frequency of 1MHz.

Group B:  To the group submitted to the OKC protocol, the data collections would

perform on a quadriceps table. The volunteers will remain seated having their

lumbar and thoracic spine supported hips and knees at a 900 flexion. Next, they will

perform five repetitions and gradually progress according to progressive resisted

exercise programme (PRE). Exercises are extension movement (concentric phase),

and flexion of the knees (eccentric phase), and one minute rest will be granted

between each set. After exercise, the subject will undergo ultrasound therapy with

the intensity of 1W/cm2 for 8 minutes using a pulsed mode 1: 1 ratio with frequency

of 1MHz.(24)

These criteria were adopted following the studies performed by Steimkamp et al.

and Escamilla et al, who suggested these angles as the most safe to perform the OKC and

CKC exercises.(14)
