Program Relationship Low Back Pain Background: Non-adherence to home exercise programmes may lead to delayed progress in recovery and diminished clinical outcomes in patients. Aims of Study: To determine the adherence rate and attributing factors to non-adherence to home exercise programmes in patients with low back pain (LBP). Method: A total of 250 patients with LBP receiving treatment in 5 different out-patient physiotherapy clinics in Lagos State South West, Nigeria participated in this survey. They were required to complete a 27- item questionnaire which collected information on characteristics of participants and home exercise programme, adherence with treatment programme and instructions for carrying out the exercises. Gamma correlation and Chi-square were used to detect the correlation and significant difference of selected variables respectively. The level of significance was set at p< 0.05 Result: Ninety-four (37.6%) respondents performed home exercise programme the recommended number of times daily. There was no significant relationship (p> 0.05) of participants’ characteristics, frequency and duration of exercise per session, total number and manner of recommending the home exercise programme and pain rating respectively with adherence to home exercise programme. Eighty-nine (35.6%) respondents complained of tiredness after the day’s work. Chi-square showed significant association (p<0.05) of the prescribed home exercises programme, the actual exercise carried out at home with their perception to home exercise programme Conclusion: Home exercise programmes may interfere with normal life and daily routine in patients with LBP. It is recommended that home exercise programme be patient centred I.e. fit into individual daily routine to overcome identified barriers.
1. INTRODUCTIONLow back
pain (LBP) is responsible for huge personal and societal costs, and is major
cause of work disability (Moffett and McLean, 2006). Epidemiological reviews
suggest that it is rising among Africans and therefore a concern for healthcare
professionals (Louw et al, 2007). Systematic reviews
also provides evidence of the benefits of exercise in effectively decreasing
pain and improving function in Low Back Pain patients (Sarig-Bahat,
2003; Hayden et al, 2005; Kay et al, 2005). Home
exercise programmes are often instructed individually and prescribed by
physiotherapists to be performed at home by the patients (Pilar Escolar-Reina et
al, 2010).For an exercise regimen to be successful, the patient must
have the knowledge and skill to perform the regimen as well as an intention to
do so (PeterandNick, 2004). Although home-based exercises vary greatly in
the methods of delivery and content (Moffet et al,
2006), different programmes appear to have similar effects on patients (Slade and Keating, 2006; 2007). Scientific
evidence suggests that inadequate adherence to home-based exercises may
attenuate the treatment's efficacy (Hayden et al, 2005; Kolt and McEvoy, 2003). Also many recurrent cases of LBP
could have been avoided if patients had adhered to their home exercise
programmes (Middleton, 2004). It has been reported that adherence to exercise
is often a serious issue for patients with LBP (Slade and Keating, 2006;
2007). Most home programmes for LBP are prescribed by physiotherapists (Poitras
et al, 2005). A problem frequently faced by physiotherapists is that patients may fail to recover from their injury in spite of the fact that there is no apparent pathological basis for this poor outcome (Bassett, 2003). This may mislead physiotherapists to wrongly think the treatment programme is not fulfilling the needs of the patients, a decision that is based solely on their physical status (Bassett, 2003). However, had the patients' psychological and behavioral responses to their injury and treatment been taken into account then it is possible poor treatment adherence might have been detected. Poor adherence to physiotherapy is a problem with up to 65% of patients being either non adherent or partially adherent to their home programmes, and approximately 10% of patients failing to complete their prescribed course of physiotherapy (Basset, 2003). Non-compliance to exercise regimen is a major obstacle to the effective delivery of health care. Estimates from the (WHO, 2003) indicate that only about 50% of patients with chronic diseases living in developed countries follow treatment recommendations which put health at risk (APA Highlights Newsletter, 2004). In particular, low rates of adherence to therapies for asthma, diabetes, and hypertension are thought to contribute substantially to the human and economic burden of those conditions (Harris, 2010). Compliance rates may be overestimated in the medical literature, as compliance is often high in the setting of a formal clinical trial but drops off in a “real-world” setting. Several systematic reviews provide evidence of the benefits of exercise among people with chronic back pain (WHO, 2003). Therefore,
patient’s adherence is
of considerable importance to physical therapy because treatment outcome partly
depends on it. The efficacy of physical exercises can only be established when
patients comply with the exercise regimen (Sluijs et
al, 1993). Hence, this study was
designed to evaluate the predictive factors of adherence to frequency and
duration of home exercise programme in low back pain. 2. METHODSA cross – sectional descriptive survey was carried out on patients with low back pain who were receiving treatment in out-patient physiotherapy clinics from three selected hospitals in Lagos, South West Nigeria. The hospitals are Lagos University Teaching Hospital, National Orthopaedic hospital, Lagos State University Teaching Hospital, General Hospital Marina, General Hospital Gbagada and Federal Medical Centre Ebute- Metta. Ethical approval was sought and obtained from the Committee on Research and Ethics of the College of Medicine Lagos University Teaching Hospital, Idi-Araba Lagos, Nigeria. All the respondents gave their informed consent. Subjects with low back pain of mechanical origin who had been receiving physiotherapy treatment for low back pain for at least one month after intervention were included in the survey. Patients younger than 18 years or older than 80 years, patients with cognitive deficit, co – morbid conditions, patients who were unable to attend all treatment sessions of physiotherapy, and patients who stopped home exercise programme by physiotherapist’s prescription were excluded from the study. 2.1. QUESTIONNAIRE DESIGNA 27-item self-administered questionnaire titled “Predictive Factors of Adherence to Home Exercise Programme” (PFA- HEP) Questionnaire was employed as the survey instrument. The initial draft of the questionnaire was adopted from previous related studies (Chappell and Williams 2002; Medina- Mirapeix et al 2009) and served as the working document for development of the final draft by a four man focus group. Prior to distribution, the questionnaire was sent to two physiotherapy educators in the College of Medicine, University of Lagos who are experts in questionnaire design to determine the content validity. The questionnaire had five sections. Section A sought information on demographic data such as age, gender, education level, work participation, sick leave or off work. Section B collected information on previous physiotherapy treatment, home exercise programmes in the previous treatment, numerical pain rating scale, extent of limitation due to pain, type of exercise given, total number of exercise given, the agreed number of days to perform the HEP, times per week, how long per session and how many times or repetitions per session. Section C was on compliance from the patients patient’s point of view and sought to elicit information about the agreed number of HEP given, extent at which the patients adhered to HEP, reasons for missing HEP, extent at which HEP had affected the patient- physiotherapist behaviour in clinical encounters such as clarity of doubts, information about illness and usefulness of the advice. Section Dgleaned data on way home HEP was given, level of clinical supervision of the exercises, follow – up received and extent of review of the HEP. The questionnaires were distributed and given to each respondent individually by the researcher (OBF) by personal visitation to all the hospitals involved in the study. 3. DATA ANALYSISData were summarized using descriptive statistics of
frequencies and percentages. Gamma correlation was used to detect the
correlation between ordinal variables and Chi-Square was used to determine the
association between other selected variables. Data collected were analyzed
using the SPSS version 17 (SPSS Inc., Chicago, Illinois, USA). The alpha level
was set at 0.05. 4. RESULTS4.1. CHARACTERISTICS OF PATIENTS A total of 250
copies of the questionnaires were distributed and all were returned and
completed satisfactorily, giving a response rate of 100%. The descriptive information
of all respondents is presented in table 1. Females and males accounted for 64%
and 35.6% of the sample population respectively., The mean age of the subjects
was 58.2±9.5 years with majority 126 (51%) above 59 years. Fewer number of
respondents 33(13.2%) were off work or on sick leave at the time of the study
(Table1). Majority of respondents 181 (72.4%) had no contact with physiotherapy
treatment prior to present episode of LBP (Table 1). Ninety-six (38.40%) of the
respondents had tertiary education and 129(51.60%) were in paid employment.
However, there was no significant relationship of the level of adherence to HEP
with the highest educational attainment(C=0.01; p=0.80) and the employment
status of the respondents (C= 0.00; p=0.99) (Table 2).Two hundred and ten (84%)
of respondents were not given home exercise programme
in previous episodes of physiotherapy treatment (Table 2). However, there was
no significant relationship between prescription of HEP in previous episodes of
pain and the level of adherence to HEP (C= -0.03; p=0.81) (Table 2). 4.2. CHARACTERISTICS OF HOME EXERCISE PROGRAMMERespondents were prescribed different types of HEP, with the majority 86(34.4%) given modified press- up (Table 3). Most of respondents,218(87.2%) do HEP every day of the week (Table 4). The total number of exercise given to respondents were grouped into three with the majority 242(98.8%) given 1-3 exercises (Table 5). There is however no significant correlation between total number of exercise and the level of adherence to HEP (C=0.14; p=0.88) (Table 4). The number of times per day agreed to carry out HEP by respondents showed that the majority 247(98.8%) performed the exercises 1-3 times daily (Table 4), though there was no significant relationship between number of times per day the exercise was performed and adherence to home exercise programme (p=0.22) (Table 5). The duration of exercise per session were grouped with majority182 (72.8%) performing the exercise for 10-15minutes (Table 4). There is however no significant relationship between the duration of exercise per session and adherence to home exercise programme (C=0.08; p=0.92) (Table 4). Number of exercise repetition per session were also grouped from 1-15 with 5 intervals. Most respondents 121 (48.4) repeated the HEP 6-10 times per session (Table 4). However, there is no significant relationship between number of repetitions per session and adherence to home exercise programme in LBP (C=-0.17; p=0.85) (Table 4). 4.3. COMPLIANCE WITH TREATMENT PROGRAMMEThe majority 94
(37.6%) of respondents complied with the agreed number of times each day, 85
(34.0%) respondents did HEP everyday but not the agreed number of times, 59
(23.6%) respondents did the HEP occasionally but missed a few days, 7 (2.8%)
respondents did the HEP when feeling unwell and 2 (0.8%) respondents did the
HEP often but missed few days and same goes for respondents who never did HEP
(Figure 2). Majority 218 (87.2%) of respondents opined that the agreed amount
of HEP was about right (Table 5). There was however no significant correlation
between opinion about agreed amount of HEP and adherence to HEP (C= 0.29;
p=0.77) (Table 5). The majority 178 (71.2%) was of opinion that the amount of
HEP they do at home was about right (Table 5). A proportion of
respondents identified between one and eighteen factors each that led to
non-adherence while some left this section blank. The reasons most respondents,
89 (35.60%) gave was: ‘I feel too tired’ (table 6). Other less commonly stated
reasons are shown in the table 6. One hundred and fifty-six respondents (62.4%)
indicated the belief that HEP helped a great deal in reducing Low Back Pain
(Table 7). The majority of respondents 231 (92.4%) reported the
physiotherapists clarified their doubt and answered questions whenever they
asked (Table 7). However, there was no significant relationship between
clarification of doubts and answering of questions and adherence to HEP (C=
-0.35; p=0.63) (Table 7).Two hundred and thirty two (98.8%) respondents
reported that physiotherapists’ gave information about illness (Table 8).The majority
232 (98.8%) justified the usefulness of physiotherapists advice (Table 8). 4.4. INSTRUCTIONS FOR CARRYING OUT THE EXERCISESHome exercise programme were given verbally to most 247 (98.8%) of
respondents while 3 (1.2%) were given in written form (Table 7). There was no
significant relationship (C= -0.35; p=0.54) between way HEP was given and
adherence to HEP (Table 7). Exercises of most respondents 238 (95.2%) were
supervised at the clinic. Follow-up exercise was received by 198 (79.2%). One
hundred and twenty-two (48.8%) of respondents HEP were reviewed regularly
(Table 8). Chi –Square analysis showed statistically significant relationship (X2 =
127.85; p= 0.00) between agreed
amount prescribed at the clinic and the amount respondents actually do at home.
Also, there was a significant relationship (X2 = 30.312; p= 0.00) between perception of respondents about
home exercise programme and amount respondents
actually do at home (table 9). 5. DISCUSSIONOne hundred percent response rate was obtained from this study unlike previous studies (Medina- Mirapeix et al 2009; Escolar- Reina et al, 2010). This may be due to the mode of distribution of the questionnaire which was by personal visitation to all the hospitals involved. The fact that there was no significant positive relationship between HEP and each of educational attainment, employment status, duration per session, opinion about agreed amount of HEP shows adherence to home exercise programme is neither influenced by how wealthy or educated an individual is. This showed that an individual’s opinion about the home exercise programme or the number of times such a programme is performed per week would not affect his or her adherence. This finding disagrees with that of Hartigan et al, (2000) who concluded that educational attainment has positive influence on adherence to home exercise programme. It also disagrees with Sluijs et al, (1993) who reported non – compliance occurred most frequently among highly educated than non- educated. In this study, it was observed that HEP had negative non-significant relationship with each of previous episodes of LBP, pain rating, total number of exercise given, times per day, repetition per session, and mode of translation of instruction for the programmes and patient’s opinion about the exercise given. This showed that patient’s previous experience of LBP or the instruction about exercise sessions and the way instruction was given to a patient about a home programme would not affect their adherence to it. These findings disagree with those of Sluijs and Knibbe (1991) and Shoo et al, (2004) who concluded that as pain frequency and intensity decreases, adherence to HEP also decreases and that during times of remission when symptoms are absent, patients lack relevant cues to continue with treatments. The difference between the findings of this work and those of the previous studies might be due to methodological differences. This study is a survey while the previous ones were prospective interventional studies. However, it can be deduced from this study that patient’s previous experience of pain and exposure to home exercise programme would negatively affect their adherence to home exercise programme. This finding does not also agree with those of Chappell and Williams (2002) and Escolar- Reina et al (2010) who concluded that the higher the number of home exercise programme given to a patient, the less likelihood of adherence to them. However, in this study a negative non-significant relationship was observed between repetition and adherence. The difference between this study and that of the later is that their study was assessed at pre and post-intervention phases while this was a onetime survey of adherence. Martinet al, (2005) reported that even when information is communicated effectively and comprehension is initially high, much of what is conveyed during the medical visit is forgotten within moment of leaving the doctor’s office. Jackson, (1992) also opined that optimal verbal communication does not exist, and the verbal communication between physicians and patients is often filled with medical terms and often impedes patients’ comprehension and retention of information. The finding that there was no significant relationship between previous experience of LBP and adherence to home programme however disagrees with Medina- Mirapiex et al, (2009) who reported that participation in HEP in previous episodes of LBP is a predictor of HEP. Also, the finding that level of pain did not significantly affect adherence to home progrmme disagrees with previous report by Sluijs et al, (1993) who concluded that level of pain is strongly associated with level of adherence. The finding of Escolar-Reina et al, (2010) showed that the more the number of home programmes, the less likelihood of adherence. However, in this study the highest number of home programme given to the majorities was ranged between one and three unlike in the later study where patients were given up to eight exercise programmes. This might have contributed to the non-significant relationship observed in this study. The reasons given for non-adherence to home exercise programme by respondents in this study is consistent with previous study (Sluijs et al, 1993). Sluijs et al, 1993 further concluded that the barriers patients perceive, was the strongest factor in noncompliance to home exercise programme. The most frequent reported barrier was tiredness after a day’s job as most of them were on paid employment. This have also been previously documented as barrier of adherence to home exercise programme (Sluijset al, 1993; Medina- Mirapiex et al, 2009). The fact that patients’ belief on the importance and helpfulness of physiotherapy HEP to the samelioration of their symptoms influence their adherence shows that adherence to home exercise programme is not determined by their perception of the importance of such programme to their health and alleviation of their symptoms. This finding disagrees with that of Chappell and Williams, (2002) on rates and reasons for non–adherence to home physiotherapy in paediatrics. There was also significant relationship between recommended amount of prescribed home exercise programme and the amount they actually do at home. Their noncompliance could be due to the fact that majorities were ranged between ages 59 and above and due to pathological and physiological effects of ageing which might have caused barriers in carrying out the prescribed exercises even though, they were given few number of home programmes. This corroborates Escolar-Reina et al, (2010) who earlier reported that when home exercise requires longer time of execution or includes exercises which are difficult to perform, adherence level will be low. 6. CONCLUSION AND RECCOMMENDATIONBased on the findings of this study, it is concluded that home exercise programme are frequently prescribed to patients with LBP in a range of 1-3 per session and at 6-10 repetitions in this environment and that patients with Low Back Pain in this environment agreed that home exercise programme helps a great deal and do it according to prescription but some perceived barriers affected their participation. It is hereby recommended that home exercise programmes should be prescribed individually to fit into
personal daily routine without interfering with normal lifestyle. Also, home
exercise programme should be patients centered with
regular review and evaluation to overcome identified barriers because it was
seen from this study that the recommended amount of physiotherapy given at the
hospital does not determine the amount patients actually perform at home. Considering
the fact that a lot of barriers can influence adherence to home exercise programme in patients with low back pain, further studies
may concentrate on given the home exercise programme
individually and follow up to determine the rate of adherence throughout the
period of prescribed exercise. Table 1: Sex, Age, Employment Status and First Contact with PT of Respondents
